DESCRIPTION

HP C2858A and C2859A DesignJet 650C plotters provide graphic displays of computer pro- gram output data. They operate with a number of computer systems and graphic terminals, using either RS-232-C or Centronics external controllers. With one of several optional, mod- ular input/output (MIO) cards installed, the plotter can operate: with an HP-IB external con- troller, within a Novell Ethernet or Token ring network, as a TCP/IP host workstation, with a LAN Manager, with Ethertalk and with Apple LocalTalk. The C2858/9A DesignJet 650C plotters will accept drawing data from Computer Aided De- sign (CAD) software programs supporting the HP-GL (vector), the HP-GL/2 (vector), HP RTL (raster), and PJL languages. HP-GL/2 is available with Kanji character sets when the Kanji ROM SIMM is installed. Postscript is also available when the PostScript ROM SIMM upgrade is installed. The HP C2858/9A DesignJet 650C plotters (see Figure 1-1) are large-format, color and monochrome, ink-jet plotters designed to plot monochrome plots on commonly available opaque bond paper, translucent (Japanese tracing) paper, vellum, or special inkjet-compat- ible drafting film. Quality color output is only supported when using HP special inkjet paper. C2858/9A DesignJet 650C plotters can produce plots on single-sheet media or roll-feed me- dia. Large format plots of high resolution and quality are generated for applications such as computer aided design (CAD), computer aided manufacturing (CAM), mapping, mechani- cal and architectural drawings, and general drafting. Five high-capacity ink cartridges are provided with the C2858/9A plotters. Selectable pen- width settings are modified to ISO standard pen widths. The cartridges simultaneously scan across the media providing 300 dpi resolution in draft and final modes, 300 dpi addressable resolution for color in enhanced mode and 600 dpi addressable resolution for monochrome in enhanced mode. C2858A plotters can plot on media sizes ranging from International Standards Organization (ISO) sizes A1 through A4, American National Standards (ANSI) sizes A through D, and architectural media sizes C and D. Model C2859A plotters can plot on media sizes ranging from International Standards Organization (ISO) sizes A0 through A4, American National Standards (ANSI) sizes A through E, and architectural media sizes C through E. Roll-feed capability allows the plotters to perform long-axis plotting in lengths up to 50 feet. 1-2 Product Information, Figure 1-1.

Installation and Configuration 3-3, USER INFORMATION AND OPERATION MEDIA GUIDELINES Guidelines on media handling are: The leading edge must be straight and each side must be loaded evenly. If the leading edge is jagged, trim it with the media knife (located in the manual holder at the back of the plotter) using the track on top of the plotter as a guide. If media is curled, load it with the curl up. The exception to this is film media, which must always be loaded with the plotting side (matte side) down. Roll media must be flush with the right edge of the core. Film should be handled by the edges or when wearing cotton gloves. Load film with the matte side down (shiny side up). MEDIA TYPE AND PRINT QUALITY DesignJet 650C plotters have several combinations of plotting modes. Each mode is depen- dent upon the color/monochrome setting, media type, and print quality settings input through the front panel. Interaction between the settings produces the ten modes. Each mode has a unique combination of print resolution, number of passes and resultant ink-drying time. Media Type is set through the front panel when media is loaded into the plotter. The front panel display prompts the user to select for sheet or roll loading and then to scroll through the menu and select for one of the five media types listed below. The menu selection should be set to match the media type being used. Opaque bond (paper) Film Special paper Vellum Translucent A front panel button allows you to plot in one of three Plot Quality modes. Continuous press- ing of the button toggles through the modes and the associated LEDs are lit indicating the current print quality mode selection. The Plot Quality modes are: Draft Final Enhanced 3-4 Installation and Configuration, Real-time switching between plotting modes is not supported. If the user selects another mode while plotting, the plotter waits until the current plot is finished and then switches to the newly selected mode. MEDIA CUTTING AND STACKING Automatic and manual cutting of plots is available on the C2858/9A. In roll media opera- tions, the user can choose between continuous plotting or cutting plots off the roll automati- cally as they are completed. Automatic cutting When roll media is loaded, whether or not queueing is ON, the plotter automatically cuts plots and drops them into the media bin. When queueing and nesting are ON, the plotter cuts each nest. The automatic cutter can be programmatically disabled. When cutting is disabled, the plotter draws tick marks at the plot margins to indicate the end of a plot or nest. The automatic cutter can be enabled programmatically or by cycling power. Manual cutting The front panel Form Feed/Cut button can be used to feed the media out and cut it after a plot is completed. Media stacking Unattended stacking of cut sheets is provided by the adjustable media bin. The user must adjust the movable shelf of the bin according to the length of the cut sheets. Bin capacity is 20 sheets. Manual cutter A manual cutter is provided with the plotter for hand- cutting of media and is stored in the manual holder on the back of the plotter. Installation and Configuration 3-5, USABLE MEDIA SIZES Media of different types and sizes can be used on the plotters. Refer to Table 3-1 for the media sizes usable on each plotter. Table 3-1.

Wide Roll LOADING ROLL MEDIA If the spindle is already loaded into the plotter, remove the spindle by opening the roll cover and pulling on both ends of the spindle to remove it from the plotter. To load roll media into the plotter, put a roll of media on the plotter spindle and insert the spindle in the plotter by performing the following steps: WARNINGBe sure that the plotter wheels are locked to preventthe plotter from moving while loading roll media. To lock the wheels, press the locking levers on the wheels to the down position. 1. Standing the spindle on the end opposite the large, scalloped media stop, pull the scalloped media stop to release the spindle from the used roll. Set the spindle aside. Turn the used roll over and slip the endcap out with your finger. See Figure 3-2. 2. Slide the roll onto the spindle with the leading edge winding clockwise. Push the endcap into the media core, making sure the tabs are flush against the edge of the roll. See Figure 3-3. 3-6 Installation and Configuration, (C) C2847-10(UM) Removing the Media Stop and Endcap Figure 3-2. (C) C2847-16(UM) Sliding the New Roll onto the Spindle Figure 3-3. Installation and Configuration 3-7, 3. Open the roll cover and insert the spindle, with the endcap at the left and the media stop at the right. Firmly push on both ends. See Figure 3-4. Roll Cover Pinchwheel Lever (C) C2847-31(UM) Installing the Spindle Figure 3-4. 4. Once the roll is in place, push the media all the way to the right, so that it’s flush against the media stop. 5. Ensure that the pinchwheel lever at the right of the plotter is down. 6. Turn the plotter ON, if it is not already ON. 7. Grasp the leading edge of the media and pull about one foot (30 cm) of media out from the roll. Check the leading edge of the media. If it appears uneven, or to ensure a straight edge, the edge will need to be trimmed. WARNINGThe cutter blade is very sharp. Use caution when using thecutter to trim or cut media. Keep hands away from the blade when cutting. Retract the blade into the cutter after use. 8. Trim the leading edge if it’s uneven. Pull it over the top of the plotter and lay it over the cutting track. Using the cutter located in the holder at the back of the plotter, cut off the first few inches of the media. See Figure 3-5. Return the cutter to the holder. 9. Load the leading edge, aligning the right edge with the perforated line on the entry platen. Push the media in until it buckles slightly as it hits the stops inside the plotter. Let go when the plotter begins to pull the media in.

Installation and Configuration 3-11, If difficulty in loading sheet media is experienced, an alternate method of loading is possible. Do the following: 1. Ensure that the pinchwheel lever is down and the roll cover is closed. 2. Raise the window on the plotter. 3. Insert the sheet into the plotter until the leading edge hits the stops inside the platen area. Align the right side of the sheet with the perforation line on the entry platen. 4. While holding the sheet against the stops and aligned with the perforation line, lower the window on the plotter. Let go as soon as the plotter begins to pull the media in. Perform steps 4 through 6 of the sheet loading procedure on the previous page to set the plot- ter for the media type being used. UNLOADING SHEET MEDIA To remove an unplotted sheet, press the Form Feed/Cut button and remove the sheet when the plotter is finished feeding it out. Another way to remove unplotted sheet media is to raise the pinchwheel lever at the right, remove the sheet, and lower the lever. CLEARING MEDIA JAMS To clear a media jam, first press the Form Feed/Cut button to see if the plotter will cut, and advance the media out. Should the jam remain, turn the plotter OFF and raise the pinchwheel lever and window to the up position. WARNINGThe steel encoder strip and automatic cutter blade inside theplotter are very sharp. Use caution when inserting hands into the plotter to clear media. If necessary, push the ink-cartridge carriage and the cutter carriage away from the jammed media. Handle only the solid plastic part of the ink-cartridge carriage and the extension on the left end of the cutter carriage. Carefully remove the jammed media from the plotter. When finished, lower the window and pinchwheel lever before turning the plotter back ON. 3-12 Installation and Configuration, PEN CHECKING Ink usage for cartridges may vary depending upon the ratio of color versus monochrome plotting and the extent of each color used. Cartridge replacement is necessary only when any of the following conditions occur: Pen Checking is ON and you elect to replace the cartridges when the plotter prompts you. Poor plot quality indicates an out of ink condition or the cartridges appear clogged. When Pen Checking is ON (default), the plotter checks the pens both before and after each plot for proper electrical contact and nozzle function. If either of the problems exist, the plotter displays the message “Service pens/Continue”, You may elect to either ignore the message and continue by pressing the Down Arrow or select “Service pens” by pressing the Up Arrow button. If you select “Service pens,” the display tells you whether a pen needs to be replaced (nozzles aren’t working) or reseated (poor electrical contact). The defective pen position is indicated by a flashing icon in the front panel display. When Pen-checking is OFF, the plotter does not check the pens for the above problems; the only way you’ll be able to tell if you need to replace or reseat a pen is if your print quality is poor. Use the ink level indicators on the cartridges to check ink levels. Perform the following steps to change the current pen checking selection. 1. Press Enter button and use the arrow buttons to scroll to the Utilities menu. 2. Press Enter button and use the arrow buttons to scroll to “Menu Mode”. Press the Enter button. 3. Use the arrow buttons to toggle to “Full” and press the Enter button. 4. Use the Previous button to return to the Status display. 5. Press Enter button and use the arrow buttons to scroll to the Plotter setup menu. Press the Enter button. 6. Using the arrow buttons, scroll to “Pen check” and press the Enter button. 7. Using the arrow buttons to toggle the options, select the option you want (“OFF” or “ON”) and press the Enter button. Installation and Configuration 3-13, Figure 3-9 shows you how to visually check the ink level in a cartridge. Checking the Ink Level Figure 3-9. ACCESSING PENS Press the Access Pens button to access the pen carriage when you need to replace, reseat, or clean pens. The pen carriage will move into the platen area to allow easy access to the pens. Each time the pen carriage moves out from its service station so that you can access the pens, the pen nozzles are exposed to the air. If the pen nozzles are exposed to the air (except during plotting) for more than a few minutes at a time, they are susceptible to clogging and drying. Each time you remove a pen from its slot and then put it back, the plotter performs the pen alignment procedure automatically. REPLACING PENS The pens should be replaced in response to a Pen Checking prompt or poor plot quality. Four high-capacity ink cartridges are used in the plotter. Pen life expectancy is dependent on the type of media and plotting mode used. To replace the pens, perform the following steps: Note The four pens must be loaded in their designated pen slots in the carriage. Use the color label on the cartridges and color dots on the carriage to match positions. The plotter should be powered on when changing pens. If you se- lected “Service pens” from the display, skip step 1. 3-14 Installation and Configuration, 1. Press the Access Pens button. The pen carriage moves out from the pen service sta- tion at the left of the plotter and stops in front of the slot in the bail. 2. When the pen carriage stops and the display reads “Open window to access pens,” open the window. Note If you don’t open the window within 30 seconds after the message is dis- played, the pen carriage returns to the pen service station. 3. Refer to the plotter display. The display indicates, via flashing icon(s), which pen position(s) is/are detected to be in need of servicing. The four icons represent the following pen positions: outer left = Y (yellow), inner left = M (magenta), inner right = C (cyan), outer right = K (black). Note In monochrome mode, only the black pen icon will appear solid, while the remaining icons are outlined. In color mode, all pen icons will appear solid. 4. Place your hand on top of the pen you are replacing and press down slightly as you pull the pen toward you. See Figure 3-10. 5. Lift the pen out of its slot. Installation and Configuration 3-15, 6. Remove the protective tape from the new pen. Insert the pen into the empty pen slot. 7. Press down slightly and push the pen away from you until it snaps into the pen slot. See Figure 3-11. Installing a Pen Figure 3-11. 8. Repeat steps 4 through 7 for each pen being replaced. 9. Close the plotter window. When “Load media to align pens” is displayed, load good quality media into the plotter. Special paper must be used to properly align the color pens. The pen alignment procedure takes about three minutes to complete. Note The plotter tests the pens to ensure proper operation. The test runs approxi- mately one minute and the display indicates the pens being tested. After test- ing, the pen alignment procedure is automatically performed. Allow the alignment procedure to complete before resuming normal plotter operation. SELECTABLE INK-DRYING TIMES User-selectable ink-drying times are available on the DesignJet 650C plotters through the front panel menus. Dry time determines how long the plotter waits before cutting the plot. Users should be cautioned that insufficient dry time can result in plot smearing as plots are stacked in the media bin. Dry time choices are accessible through the Plotter setup menu. 3-16 Installation and Configuration,

Chapter 5 Functional Overview INTRODUCTION

This chapter contains a simplified description of the HP C2858A and C2859A DesignJet 650C plotters circuits and mechanical functions. Mechanical and Printed Circuit Assembly (PCA) overviews present a functional description of how the plotter operates. Introduction .5-1 Simplified Description of Circuits .5-2 Mechanical Overview .5-3 Printed Circuit Assembly (PCA) Overview .5-5 Main PCA .5-5 Carriage PCA .5-6 Interconnect PCA .5-7 Front Panel PCA .5-7 Drop and Bail Sensors .5-8 Power Supply PCA .5-8 Functional Overview 5-1, SIMPLIFIED DESCRIPTION OF CIRCUITS HP C2858A/59A DesignJet 650C circuits communicate with an external controller by way of either a Centronics or an RS-232-C interface. If an approved modular input/output (MIO) printed circuit assembly (PCA) is installed, the circuits can communicate by way of an HP- IB interface or be connected to a network. The main processor reads Centronics, HP-IB, and Ethernet communications through the port it uses to read memories (ROM or DRAM). RS-232-C communications are handled by a universal, asynchronous, receiver-transmitter (UART) and baud rate generator built into the processor support application-specific inte- grated circuit (ASIC). HP DesignJet 650C plotters accept plots in Hewlett-Packard Graphics Language (HP-GL), Hewlett-Packard Graphics Language 2 (HP-GL/2) or Hewlett-Packard Raster Transfer Lan- guage (HP RTL) form. The main processor converts the plot into an internal format and stores the entire plot in its dynamic random-access memory (DRAM). Then it transfers the plot a swath at a time into the swath RAM by way of the processor support ASIC. On the main PCA, the processor support ASIC is designed to manipulate swath data into the actual firing order for the pen nozzles on the four pen cartridges that are mounted on the car- riage assembly. The processor support ASIC receives pixels from the physical swath RAM and sends them serially to the carriage ASIC. A main processor on the main PCA controls all plotter operations with the help of the proces- sor support ASIC and the servo processor. Communications between the servo processor and the main processor take place through registers in the processor support ASIC. The processor support ASIC provides pulse-width-modulated signals to the Y-axis motor driver and the X-axis motor driver to drive the Y-axis (carriage) motor and the X-axis (paper) motor. The linear encoder connected to the carriage PCA gives the processor support ASIC feedback about the position of the carriage. The X-axis motor encoder on the X-axis motor gives the processor support ASIC feedback about the position of the X-axis motor. In addition, the processor support ASIC contains a DRAM controller that generates multi- plexor control and enable strobes for the DRAM row and column addresses during a memory access. The DRAM controller also arbitrates between a memory request and a refresh re- quest, and it performs the refresh operation. The servo processor communicates with the main processor through registers in the proces- sor support ASIC. The servo processor writes information into the registers and sends an in- terrupt to the main processor. The main processor then reads the registers and the interrupt is automatically cleared. Using this procedure, the servo processor provides the main processor with information from the plotter sensors. The sensors give the main processor the ability to check status conditions. 5-2 Functional Overview, The servo processor controls the servo motors, front panel, fan, electrically erasable read-on- ly memory (EEROM), and the stepper drive. It sends configuration information to the car- riage processor via its serial port. The EEROM stores plotter calibration and configuration information while power is OFF. The stepper drive moves the stepper motor. The stepper mo- tor is used to raise the pen wiper for wiping pens or to operate the pen service station. A line sensor on the carriage PCA provides the servo processor with information used to align the pens. It also provides a media edge sensing capability to the plotter (for width mea- surement). The carriage ASIC controls the firing of the pens. It receives pixel data from the processor support ASIC over a synchronous serial channel. It contains a 100-bit shift register (one bit per pen nozzle), which performs a serial-to-parallel conversion on the data. It contains tim- ing, sequencing, and delay circuitry to ensure that pen nozzles are fired in the correct se- quence and at the correct time. It also contains fire waveform generators to create the fire- pulse waveforms used to fire the pens. Pen drivers provide the power necessary to fire the pens under the control of the carriage ASIC. During pen testing, the processor support ASIC provides a means to generate a fire position pulse when the carriage is docked in the service station. The carriage ASIC will receive this signal and fire selected nozzles. If a drop is sensed by the drop detector each time a nozzle is fired, the nozzle is working properly. The independently generated fire position pulse is also used for warm-up pulse generation and for firing to clear clogged nozzles. MECHANICAL OVERVIEW The Y-axis (carriage) motor is mounted under the plotter’s right endcover. It is electrically connected to the interconnect PCA, which contains a Y-axis motor driver. Its drive shaft is mechanically connected to the carriage by way of a small drive belt, double pulley, and main drive belt. When the carriage motor rotates, it moves the carriage assembly. An optical en- coder, located on the carriage assembly, provides position feedback for Y-axis servo control. The line sensor, also mounted on the carriage assembly, is used to detect and measure lines when performing pen alignment and the accuracy calibration. The line sensor is also used to detect media width and skew during media loading. The X-axis (paper) motor is also mounted under the right endcover and is electrically con- nected to the interconnect PCA which contains an X-axis motor driver. It has a worm-style pinion gear which meshes with a gear at the right end of the drive roller. When the paper mo- tor rotates, it moves the drive roller and, consequently, the media. The encoder mounted on the motor sends feedback about the X-axis motor position to the main PCA. Functional Overview 5-3, An internal cooling fan is supplied with +12 V. It is switched ON and OFF by the servo pro- cessor and is mounted in the electronics enclosure at the rear of the plotter. The fan is primari- ly used to cool the power supply PCA when plotting. When the plotter is not plotting, the fan is switched OFF. At high temperatures, the fan is switched ON. The window sensor is a switch mounted on the right sideplate at its top front edge. Feedback about the window’s position (up or down) is sent to the main PCA through the front panel. An optical pinch wheel sensor is mounted on the lower rear portion of the plotter’s right side- plate and is electrically connected to the main PCA. When the pinch arms are raised, a cam in the pincharm lift mechanism interrupts the beam of the optical sensor, and, when the pin- charms are lowered, the beam is not interrupted. Thus, the position of the pincharms can be determined from the electrical state of the sensor. The media sensor is also an optical sensor and is mounted toward the right end of the entry platen. A reflective label, located under the cutter enclosure, provides a reflective surface for the sensor. A base intensity level for reflected light is determined for the sensor in the absence of media. This intensity level is stored in the EEROM. It is calculated when a new main PCA with a blank EEROM is first powered-up, or after the EEROM has been cleared. When media is loaded, a difference between the new intensity level and the base intensity level indicates that media is present. This sensor provides a leading and trailing edge-sensing capability (for media length measurement) to the plotter. The media sensor is electrically connected to the main PCA. The drop sensor is an infrared detector mounted in the service station. It is used to test that the nozzles in the pen cartridge are operating properly. It is part of a drop-detection system that measures the time from the firing of a nozzle to the sensing of a drop (typically < 900 sec). The operation of the sensor system depends upon an illuminated infrared optical path, in which the received power is modulated a small amount by a drop passing through an aperture on the way to the waste containment system. The illumination is provided by an infrared LED which is regulated by an automatic power control to provide a fixed operating point in the optical receiver photo-diode. The automatic power control compensates for contamination, device aging, and environmental effects. An optical sensor mounted on the primer assembly is used to determine the initial position of the primer assembly cam. When the stepper motor that drives the primer assembly rotates in one direction, it obtains the values for selecting each pen for priming. When rotated in the opposite direction, a clutch engages a diaphragm to provide the vacuum for priming. An optical sensor on the service station housing is used to determine the position of the bail. When the bail is in the “down” position, the photo beam is interrupted by a small plastic flag actuated by the bail. When it is up, the photo beam path is clear. The resulting BAIL logic level is sent to the main PCA by way of the service station cable. The service station cable assembly consists of the drop detect and bail sensors, the stepper motor and the primer sensor. 5-4 Functional Overview, PRINTED CIRCUIT ASSEMBLY (PCA) OVERVIEW MAIN PCA There are two clocks on the main PCA. The main clock provides a 31.85 MHz signal directly to the main processor. The 31.85 MHz is divided by the main processor, and the resulting signal is provided to the processor support ASIC. A separate clock provides a 12 MHz signal to the servo processor. In order to perform its functions, the main processor must have access to its memories (ROM and DRAM). To create plots at the direction of an external controller, it must be able to com- municate with the controller by way of its interfaces (MIO, Centronics, and RS-232-C). To address the ROM or DRAM interface, the main processor places the appropriate address on the address bus and reads or writes the data directly. Data is passed to the main processor by a transceiver in the case of ROM or DRAM SIMM data. MIO or Centronics input and output data pass through another transceiver on its way to the main processor. The main PCA ROM contains the following types of information: Programs Program constants Character sets Demonstration plot The main PCA DRAM is used to store the following types of information: Variables Temporary constants Plots As a plot is received from an external controller by way of one of the plotter interfaces, it is stored in DRAM. When the complete plot is in DRAM, the main processor converts it, one swath at a time, to a format suitable for storage and sends it to swath RAM by way of the processor support ASIC. A swath is 96 dots high and extends from border to border across the width of the plot. The processor support ASIC extracts the plot data from the swath RAM, converts it to pixels, and sends the pixels serially by way of the trailing cable to the carriage ASIC on the carriage PCA. Functional Overview 5-5, CARRIAGE PCA The carriage PCA contains an application-specific, integrated circuit (ASIC) that controls the operation of the pens and pen drivers that switch power pulses from the ASIC to fire the pens. It also provides feedback to the main PCA as to the current position of the carriage as- sembly. A line sensor module mounted on the carriage PCA monitors the lines produced by the pens and is used for pen alignment. The line sensor also provides an edge sensing capabil- ity used to identify the media loaded in the plotter. Voltage sense circuitry senses deviations in the pen voltages supplied to the print heads and sends signals to the voltage regulators on the interconnect PCA. The carriage processor and the print control ASIC on the carriage PCA are driven by a 12.288 MHz, on-board clock. At power-on time, the main PCA reset circuit delays the operation of the print control ASIC until the +5 V reaches a steady state. The line sensor module is used to calibrate the writing system for mechanical tolerances as well as to sense the left and right edges of the media. It consists of a photo-diode device whose photo-current is amplified by a transimpedance amplifier connected to the PCA through a ZIF connector. The resulting voltages are coupled and then measured by an eight- bit, analog–to–digital (A/D) converter whose bits are sent serially to the carriage micropro- cessor. Illumination of the surface being read by the line sensor is provided by two green, high-intensity LEDs. A dual lens, unity conjugate ratio system directs the light from the illu- minated surface to the sensor-phase plate combination. A temperature sensor IC is used to measure ambient temperature near the print heads. Energy used to fire the pens is based on temperature. This temperature reading is also used to deter- mine when to switch the fan ON. Normally, the fan only runs when plotting. At high tempera- tures, it is left ON. A linear encoder detects pen carriage position as the carriage assembly moves along the en- coder strip. The linear encoder IC is connected to the carriage PCA via a 5-pin ZIF connector. The carriage processor operates at 12.288 MHz. The clock signal is generated by a crystal- oscillator circuit internal to the ASIC. The primary task of the processor is to configure the print control ASIC and read data to control pen energy and pen calibration. It communicates with the servo processor on the main PCA using a serial port. The print control (carriage) ASIC receives pixel data from the processor support ASIC on the main PCA via a synchronous serial channel and on–board line driver. Signals from the print control ASIC fire the nozzles in the print heads. Whenever a print head nozzle is fired, a com- parator outputs a pulse to a counter in the carriage microprocessor. 5-6 Functional Overview, The dual-voltage, remote sense circuitry sends a + or – sense signal to the dual voltage regu- lators on the interconnect PCA when the voltage to the print heads deviates from the opti- mum pen voltages. The regulator will then adjust the voltage to bring it back to the optimum value. Pen voltages are ON when printing a swath and briefly at power-up, but OFF when idle or accessing pens. INTERCONNECT PCA The interconnect PCA contains an X-axis (paper) motor drive, a Y-axis (carriage) motor drive, a switching pre-regulator, two linear regulators for the black and color pen voltages, and direct paths for the MIO lines to the main PCA. The drivers and the voltage regulator receive +24 Vdc via the main PCA. The pre-regulator steps down the +24V to +19.5V for the two linear regulators. The two linear regulators output voltages from +9 to +15V and receive + and – sense signals that originate at the carriage PCA and then routed through the main PCA on their way to the interconnect PCA. When the pen voltages delivered to the pen car- tridges deviate above or below their respective values, the sense signals will cause the volt- age regulator outputs to move to counter the deviation. Part of the pen shutdown circuitry resides on the interconnect PCA. The pens are shutdown when the +5V falls below a certain value (during power-up/down), when the carriage ASIC asserts shutdown during an access pens command, between swath printing or when idle. The interconnect PCA receives PA and PB drive signals for the paper motor driver and the carriage motor driver from the processor support ASIC on the main PCA. PA and PB are pul- se-width-modulated (PWM) signals. The PA signal to the paper motor driver causes the pa- per motor to drive the paper up and out of the front of the plotter. The PB signal to the paper motor driver causes the paper motor to drive the paper down, over the entry platen and out of the the plotter. The PA signal to the carriage motor driver causes the carriage motor to drive the carriage toward the right side of the plotter. The PB signal to the carriage motor driver causes the carriage motor to drive the carriage toward the left side of the plotter. FRONT PANEL PCA The front panel consists of a 2-row by 20-character, vacuum-fluorescent display (VFD), seven LED indicators, and a 10-button key pad. The servo processor on the main PCA writes serially to the VFD and the LEDs and reads the key pad on its input/output lines. It provides for local control, configuration and testing of the plotter and serves to display various plotter conditions. Functional Overview 5-7, DROP AND BAIL SENSORS The drop sensor is located in the drop detect assembly. Its purpose is to detect ink drops dur- ing pen testing. The drop sensor contains a detector system capable of detecting the presence of a drop shortly after one is fired into the detector. In order for the drop to be fired into the detector, the pen must be positioned over the sensor. An infrared LED sends a beam across an aperture. The beam is received at the other side by a photo-sensitive diode. When a drop passes through the beam, it causes a disturbance in the reception. The slight modulation in power output by the receiving diode is amplified by the pre-amplifier, further amplified by the amplifier, and sent to the processor support ASIC on the main PCA. The processor sup- port ASIC can measure the time between the firing of a print head nozzle and reception of the amplified, drop-detect signal, typically less than 900 microseconds. The bail sensor consists of a photo-emitting diode and a collector. When the bail is down, the path between the diode and the collector is interrupted by a small plastic flag, and the BAIL signal is 0 V. When the bail is lifted, the path between the diode and the collector is clear, and the BAIL signal is +5 V. The bail signal is sent to the servo processor on the main PCA. POWER SUPPLY PCA An auto-ranging power supply for the DesignJet 650C plotter is located in the electronics enclosure assembly. It accepts and automatically adjusts to an ac input of 90 V through 264 V and produces regulated voltages of +5 V, +12 V, and –12 V and an unregulated +24 V. These voltages produced by the power supply are used as follows: +24 V Motor drivers and voltage regulator on the interconnect PCA. (Regulated +9 to +15 V for pen circuits on the carriage PCA). +12 V Fan power, MIO and RS-232 driver. –12 V RS-232 driver. +5 V IC power and sensors, drop sense PCA. In the primary portion of the supply are contained fusing and input protection circuitry, line filters, and a rectifier. The primary output is converted to a pulse-width-modulated (PWM), unidirectional current by a flyback dc-to-dc converter. The secondary portion of the power supply contains the four secondary windings of the trans- former that convert the PWM current in the primary to four ac voltages which are rectified to the +5 V, +12 V, –12 V and +24 V dc voltages required by the plotter. Standard +12 V and –12 V regulators are included in the secondary portion of the power supply. 5-8 Functional Overview,

ADJUSTMENTS

There are no electrical or mechanical adjustments required on the HP C2858A and C2859A DesignJet 650C plotters.

CALIBRATIONS

DesignJet 650C plotters have several calibration procedures that must be performed under certain conditions. Refer to Table 7-1 to determine when calibrations are required. Table 7-1. Calibration Requirements Indications or Repairs Performed Calibration Required Hardclip limits not within specification Sheet Length Calib Platen (drive) roller is replaced Accuracy Calib X-axis motor/encoder is replaced Accuracy Calib Config Plot X-mark distance is not Accuracy Calib 500mm (1mm.); mono on inkjet film Media sensor is replaced Media Sensor Calib Plotter does not detect media presence Media Sensor Calib Plotter tries to load media, none present Media Sensor Calib Drop Sensor is removed or replaced Drop Detect Calib Pen checking constantly rejects pens Drop Detect Calib Pen service station is removed or replaced Drop Detect Calib Carriage or Carriage LED is replaced Edge Sensor Calib Edge detect failures occur Edge Sensor Calib Bail failures occur during media loading Bail Calib EEROM is cleared or replaced All in the following order: 1. Media Sensor Calib 2. Bail Calib 3. Drop Detect Calib 4. Edge Sensor Calib 5. Accuracy Calib 7-2 Adjustments/Calibrations, All calibration procedures are accessible through the front panel menu structure. Procedures accessed by users are available through the “Utilities” main menu. These procedures include Pen Alignment and Accuracy submenus. The Accuracy submenu contains two lower subme- nus, Restore Factory settings and Recalibrate procedures. The Config Plot function, also lo- cated in the “Utilities” menu, is used in conjunction with the Accuracy procedures for com- parison purposes. Procedures reserved for service use are available through the “Service Tests” menu, which is a subset of the “Utilities” menu. SHEET LENGTH CALIBRATION This calibration uses the X-axis to correct for tolerances in x-axis components that are used to measure media length during media loading. Perform this calibration if the hardclip margins are not within the 2 mm specification. Sheet Length Calibration is accessible through the “Service Tests” menu. To perform the sheet length calibration, do the following: 1. Press Enter at the “Status” display. 2. Use the arrow buttons to scroll to the “Utilities” main menu. Press Enter. Either the Short or Full menu mode will access the “Service Test” submenu. 3. Simultaneously press the Enter and the Up Arrow buttons to access the “Service Test” submenu. 4. Scroll to the “Sheet Length Calib” submenu. Press Enter. 5. Messages in the plotter display will inform you to load cut-sheet media in a land- scape orientation. Any standard size or type of media may be used. 6. The plotter will scan across the media, accurately locating the media edges. 7. The sheet must then be removed, rotated 90, and reloaded into the plotter. 8. The media edges are again scanned and the calibration is completed. 9. Check the margins by measuring the hardclip limit borders on the Configuration Plot. Adjustments/Calibrations 7-3, ACCURACY CALIBRATION Performance of these accuracy procedures allow you to either restore the plotter to the facto- ry accuracy settings or to recalibrate the plotter to the current environment. Accuracy calibra- tion constants are stored in the plotter EEROM. When performing the accuracy calibration from the “Service Test” menu, the factory correction value will be recalculated. This will be the new factory default calibration value. The calibration performed from the “Utilities” menu will calculate a new user calibration value. This value will override the factory value until the plotter is reset from the “Resets” submenu. Once reset, the plotter will use the factory default until another user calibration is run. Check the accuracy calibration whenever the: Before performing an accuracy calibration, run a configuration plot. An accuracy calibration is needed if the distance between the centers of the “X” marks on the configuration plot is not 500 mm (20 in.) 1 mm (0.04 in.) under normal environmental conditions. Media expansion and thickness can affect endpoint accuracy. The plotter endpoint accuracy is specified on ink- jet polyester film only, at 0.2% of the specified vector length. If the measured accuracy, media thickness, or environmental conditions vary greatly from the factory standards, recalibrate the plotter using the following procedure. To perform the accuracy calibration, use the following steps: Note ‘User’ and ‘service’ accuracy calibration procedures are similar. Follow the appropriate ‘user’ or ‘service’ noted paths in the steps. 1. Place a sheet of media over the top of the plotter for 10 minutes to let it stabilize to the environmental conditions. Use a sheet approximately 24 x 36 inches (61 x 91 cm). Roll media may also be used. Use polyester film when performing the Accuracy Calibration from the “Service” menu. If using inkjet polyester film, load the film with the matte (dull) side down. 2. Load the media. If using D-size media, load the short edge as the leading edge in C2858A plotters and the long edge as the leading edge for C2859A plotters. The C2859A can also use E-size media. Both plotters can use polyester film roll media for this procedure. 7-4 Adjustments/Calibrations, 3. Press Enter at the “Status” display. 4.

DIAGNOSTICS

Several types of built-in diagnostic and service tests reside in the DesignJet 650C plotters. These troubleshooting aids include power-on self tests and mechanical initialization rou- tines. In addition, worded error messages; system error codes; and internal service menu tests are provided. POWER-ON SELF TESTS HP C2858A/9A DesignJet 650C plotters will automatically perform a series of internal self tests, as well as certain initialization sequences, whenever the plotter is switched ON. These self test and initialization sequences are described in the following paragraphs. As the plotter moves through the tests, a series of dots will quickly appear on the display. During a failure condition, a failure analysis may be performed by either noting the number of dots present on the display or interpreting the worded message or system error code message displayed. POWER-ON SELF TEST Self-tests normally run when the plotter is switched on are: 1. Servo processor initialization. The display will read “Servo processor initialized” when initialization is complete. If the servo processor cannot initialize, replace the main PCA. 2. The main processor initializes. One dot “.” will be displayed when complete. If this portion of the test fails, replace the main PCA. 3. The main processor to servo processor communication path is tested. If this portion of the test fails, replace the main PCA. 4. The ROM checksum is tested. Successful completion of this test will cause two dots “..” to be displayed. If this portion of the test fails, first replace the EPROMs. If re- placing the EPROMs does not correct the error, replace the main PCA. 5. The main processor initializes certain firmware modules and communicates with the carriage processor. If these tests pass, three dots “...” will be displayed and the “Pa- per” LED will be turned ON. 8-2 Troubleshooting, !# ! "!" "! " " "!" ! * " # " " #!""! ! " " # " #!""! ! " & " " ! $ !!

" "(* " % MECHANICAL INITIALIZATION During mechanical initialization, the following tests are performed: 1. The window sensor is checked. The initialization will not continue unless the win- dow is in the “down” position. 2. The bail sensor is checked and the pen primer assembly is initialized. 3. The Y-axis is initialized. First the left stop is found, then the right (contact with the cutter is made). The carriage then parks in the service station. 4. The pinch wheel position sensor is checked. If the optical sensor does not see light, the plotter will act as if the pinch wheel lift lever is UP. 5. The media sensor is checked. If the optical sensor does not see light, the plotter will act as if media is already present. A bad sensor could cause the plotter to try to load media with media present or drop media out of the plotter during the rear edge search (if sheet media is loaded at power ON). After the mechanical initialization is com- plete, the plotter is placed into a ready state (either to accept media or to plot). 6. X-axis feedback operation is checked. 7. Remainder of DRAM tested. Troubleshooting 8-3, ERROR MESSAGES AND CODES Two types of error messages can be viewed in the front panel display: WORDED ERROR MESSAGES Worded error messages indicate that a user error or an internal error has occurred. Some error messages require action to clear, and others are only displayed until the next operation is per- formed by the plotter. See Table 8-1. Table 8-1. Worded Error Messages Message Error/Action Alignment error The plotter experienced an internal alignment failure. The Continue window was lifted, or the front panel was used to perform some other action while pen alignment was proceeding. Press the “down” arrow to continue. Rerun pen alignment.

Open the roll cover Reload roll and push the media roll all the way to the right so that it is flush against the media stop on the roll core. Reload, making sure that the left/right media edges are even with the left/right roll core edges. RS-232 error The RS-232-C interface is configured incorrectly. Press the Baud, parity ENTER button to clear the message from the front panel display. Check the baud rate and parity settings in the plotter’s front panel, in the hardware configuration, and in the application software configuration. Adjust the setting as needed to ensure compatibility. This error can also indicate a framing error caused by the wrong number of start/stop bits sent or the wrong data word length. The plotter expects 1 start bit, 7 data bits, 1 parity bit, and 1 stop bit. RS-232 error The RS-232-C interface is configured incorrectly. Press the Handshake ENTER button to clear the message from the front panel display. Check the handshake settings in the plotter’s front panel, in the hardware configuration, and in the application software configuration. Adjust the settings as needed to ensure compatibility. Service pens Pen checking is ON and an error has been detected. Press the Continue UP ARROW if you want to service the pens (replace or reseat). Press the DOWN ARROW if you want to continue without servicing the pens. Sheet misaligned Sheet media is skewed. Remove it and reload it so that the Reload sheet left/right edges being loaded into the plotter are square. The leading edge must be straight. Switch power off A servo shutdown has occurred in the X-axis. The drive roller Check media path cannot move or the roll feed spindle cannot freely rotate. The plotter may be jammed with media. Switch the plotter’s power OFF. Check the media path and clear it if necessary. If necessary, troubleshoot the X-axis mechanics and circuitry.

Check the drop sense cable connections. Replace the drop sensor. 0f0000 Firmware error. Notify the HP Response Center or the nearest HP Sales and Support Office. 8-10 Troubleshooting, DISPLAY DATA PLOT Display data is a plot feature, located under the “Utilities Menu’, that allows you to plot the first and last 1000 bytes of graphic instructions of a plot file sent. This feature can be used to ensure proper data reception. The instructions will be plotted in ASCII. format. To use the Display Data feature, do the following: 1. Remove any media from the plotter and make sure the plot queue is empty. 2. Enter the “Utilities” menu and select “Display Data”. A front panel message will instruct you to send the plot file to the plotter. 3. When the plot file has been completely sent, press the front panel Enter button. 4. Load a sheet of A or A4 size media (portrait orientation). The first 1000 bytes of the plot file will be plotted. 5. Remove the sheet and load another sheet of A or A4 size media. The last 1000 bytes of the plot file will be plotted. SERVO CONTROL SYSTEM FAILURES All 0300XX error codes indicate a failure of the hardware or associated electronics of the X-axis (Paper axis) or the Y-axis (Carriage axis) servo control system. An X-axis shutdown may cause either a system error code or the worded display “Power Off Check media path”. For the X-axis shutdown, first check for binding in the X-axis mechanics due to a paper jam. Also check to see if the supply roll is out of media. Tape which secures the media to the roll may cause a jam as it is pulled through the drive roller system. Removing the two screws which attach the worm gear to the drive roller should allow the drive roller to be manually spun. If it does not, it is probably jammed. Other areas to check would be the X-axis motor encoder, interconnect PCA, and main PCA. Use the X-axis motor encoder and X-axis motion control tests, found in the service menu, to help troubleshoot. A Y-axis shutdown may cause either a system error code or the worded display “Power Off Check pen path”. For a Y-axis shutdown, first check for binding in the Y-axis mechanics. Binding may be caused by a paper jam. When the plotter is switched OFF, the carriage can be manually moved along the Y-axis. Check for any areas where the carriage may be binding. Also check the reduction pulley, small drive belt, small belt tensioner, main belt, main idler, and carriage bushings. In addition to mechanical binding, a problem in the servo feedback and motor drive systems should also be checked. Check the encoder strip, interconnect PCA, main PCA, and carriage. Use the Y-friction, Y-encoder, Edge detect, and Cutter tests, found in the service menu to help troubleshoot. Excessive Y-axis friction can be caused by binding in the Y-axis or in the cutter. Use the Y-friction test, found in the service menu, to determine it the problem is caused by the cutter. Troubleshooting 8-11, TROUBLESHOOTING TIPS Certain failures, such as the media sensor and pinchwheel sensor, will not allow access to the service menu after the normal initialization process occurs. The front panel will be locked at this point. To alleviate this situation, perform the following steps: 1. Unload media (if present). 2. Switch OFF the plotter. 3. Simultaneously press the ENTER and UP ARROW buttons while switching ON the plotter. Performing the above steps will cause the plotter to stop short of complete initialization. The display will read “STATUS: Initializing”. The “Service Tests” menu can now be accessed from the “Utilities” menu in the normal way. After a repair has taken place, consider if any calibrations were affected. The demonstration plot and configuration plot can be used to help diagnose problems. Proce- dures for running the demonstration plot are given in chapter 3 of this manual. The demon- stration plot has no special diagnostic features built in, but can be used to look at overall print quality including smoothness and straightness of lines, arcs, circles, and characters. Proce- dures for running the configuration plot are given later in this chapter. ROM CODE REVISION LEVEL When powered on, the plotter scans the ROM SIMM slots from top to bottom in sequence and determines the presence of any code revision level upgrades. If any upgrade modules are present, the plotter executes the first code upgrade encountered and overrides the code level resident in the ROM on the main PCA. Typically, any ROM SIMM code upgrade will be a higher level than that on the main PCA. The only way this could be reversed is if new main PCA ROMS were installed while an older revision level ROM SIMM was left in the plotter. This latter situation should be avoided and checked whenever new ROMS are installed on the main PCA. If a code upgrade ROM and an enhancement ROM (ie: KANJI) are both installed, the code upgrade ROM must be in the upper ROM slot. If the code upgrade ROM SIMM is placed in the wrong slot, the plotter will lock up, displaying a two dot pattern. Firmware code revision levels can be checked using the Utilities main menu and Statistics submenu accessible through the front panel menu structure. 8-12 Troubleshooting, SERVICE TESTS HP DesignJet 650C plotters have numerous internal service tests that can be used in trouble- shooting. To access the service tests menu, perform the following steps: 1. Switch the plotter ON. Note Certain plotter failures that can occur will prevent the plotter from reaching the “STATUS Ready for Media” state. If one of these problems occurs, switch the plotter OFF. Press and hold down the ENTER and the UP ARROW buttons while switching the plotter ON. This will allow access to the service tests. 2. Press the ENTER button. 3. Use the ARROW buttons to scroll to the “Utilities” menu display. Either the Short or Full menu mode will access the “Service Tests” submenu. 4. Press the ENTER button. 5. Simultaneously press the ENTER and the UP ARROW buttons to access the “Service Tests”submenu. 6. Use the ARROW buttons to scroll through the test selections. 7. Press the ENTER button to begin a specific test when the desired test is displayed. Note If no button is pressed for 1.5 minutes, the front panel will return to the “Status” menu. In some cases a quick press of a button may not be recognized by the proces- sor. When pressing a button, be sure to press it deliberately and all the way to the bottom of its travel. If the plotter hangs up during a test, cycle plotter power and restart the test. In some cases the plotter may revert to the “STATUS” message upon exiting a test. To return to the service menu, perform the above steps. Service test names, descriptions, and the assemblies tested are listed in Table 8-3. Troubleshooting 8-13, Table 8-3. Service Tests Test Description Assemblies Tested EEROM (Clear) Allows you to either clear or test the EEROM EEROM. Clearing defaults all set-up values, Main PCA clears calibration values and calculates a new EEROM checksum. The EEROM should only be cleared in event of a checksum failure. After clearing, cycle power without media, and do the following calibrations in the order listed: bail calibration, media sensor calibration, drop detect sensor calibration, edge sensor calibration and accuracy calibration. It is recommended that a configuration plot be run from the Utilities menu for setup reference. Reconfigure front panel set-ups. EEROM (Test) Reads all EEROM constants into RAM for temporary storage. Writes and then reads the numbers, AA(hex) and 55(hex) into the EEROM. The EEROM constants are restored when the test is complete. THE TEST MUST BE ALLOWED TO COMPLETE. Switching the power OFF during the test will cause all EEROM constants to be lost. EXIT by pressing the ENTER button. Serial I/O Verifies the RS-232 interface’s ability to send Main PCA and receive data The special loopback connector (P/N 07440–60302) must be used with this test. If a connector is not available, you can place a jumper between pins 2 and 3 of the plotter RS-232 port for the test. Any display other than “PASS TEST PRESS ENTER” indicates the test failed. Refer to the system error code table for error code interpretation if a system error is displayed. To EXIT press the ENTER button.

'$&! % & &*& !% ! & ! & &% %&!$ & Draft Mode should not be used when performing the configuration plot as the patterns drawn will be different than described above. To run the configuration plot, perform the following steps: 1. Switch the power ON. 2. Load D-size or E-size media (either sheet or rollfeed). 3. Ensure that the plotter is in the Full (long) menu mode. 4. Ensure that the plotter is in the “Final” as opposed to the “Draft” mode. 5. From the “Status” menu display, press the ENTER button. 6. Using the ARROW buttons, scroll to the “Utilities” menu. 7. Press the ENTER button. 8. Using the ARROW buttons, scroll to the “Config Plot” menu. 9. Press the ENTER button. Troubleshooting 8-19, 10. The “busy” LED on the front panel will light to show that a configuration plot is being generated, the pens will be tested at the service station, and the configuration plot will automatically run to completion. BAR PATTERN ANALYSIS The configuration plot has several special diagnostic features built in. The four sets of color bars printed along the top represent the four specific pen locations being checked. Each pen position is tested for missing nozzles, nozzle directionality and vertical line straightness. A 10X magnifier should be used to look at the patterns. Perfect patterns should be parallel lines equally spaced. Some slight errors in direction (meaning the ink dots are not being fired straight) are due to nozzle imperfections and cannot be fixed. Others may be caused by nozzle contamination. These can sometimes be corrected by cleaning the nozzles. The solid area fill checks for ink flow problems. There should not be any white space or fad- ing of color through the pattern. The lower portions of the bars can be used to check nozzle directionality and vertical line straightness. If a problem occurs, try wiping and/or replacing the pen. The vernier scales show how well pens are aligned to each other. The center lines should match. If they don’t, a pen alignment is needed. Horizontal lines next to the vernier scales are composed of separate line segments created with different nozzles. A missing segment indicates a defective nozzle. Patterns of missing segments indicate a poor connection between the pen and the pen carriage. Use the samples below to assist you in analyzing possible print quality problems. 1. Problem: Nozzle pattern out with corresponding light band. Cause: Defective pen interconnect. 2. Problem: One nozzle out on pen, missing nozzle. Cause: Defective pen nozzle. 3. Problem: Pen short, diagonal pattern of nozzles out. Cause: Defective pen. 4. Problem: Intermittent printing, lines not straight. Cause: Defective pen. 8-20 Troubleshooting, READING THE EEROM TEXT BLOCK Contents of the EEROM IC are printed during the configuration plot in hexadecimal form. Sample portions of the EEROM contents block and the pen nozzle test block are presented in the following pages of this chapter to assist you in interpreting the configuration plot results. To read the EEROM contents block, perform the following steps. 1. Examine the sample EEROM memory map (Table 8-4) to find the memory address of the data you want to read. 2. Locate the position of the memory address in the contents text block using the memory location key in Table 8-5. 3. Read the contents of the memory address from the configuration plot EEROM text block. Suppose you are interested in knowing the factory platen correction factor. Examining the EEROM memory map you would find that the memory address of the factory platen correc- tion factor is 60. Using the memory location key, Table 8-5, you would locate address 60 just to the right of the “60” entry. On the sample contents block, Table 8-6, address 60 contains the factory platen correction factor of hexadecimal number 50. ANALYZING THE PEN NOZZLE TEST BLOCK The blocks of numbers on the lower right portion of the plot can be used to determine particu- lar pen nozzle problems. From left to right, the blocks represent the black, magenta, cyan and yellow pens. Each block has a matrix of 5 digit codes. These codes are used to determine a pen nozzle pass or fail condition. Each code digit represents a pen “squirt” test. For the black pen, all the codes in the block should read 00001, indicating a good pen. If any of the nozzle position codes read a code of 2 or higher, that pen nozzle is defective. For the color pens, the codes should read 00005. A code of 5 indicates the pen nozzle passed 5 out of 5 tests. A code of A means the pen nozzle passed 5 out of 10 tests, while a code of 8 means 8 of 10 tests passed. A code of B in the matrix means that particular pen nozzle has failed the test. Troubleshooting 8-21, Table 8-4.

Chapter 9 Product History INTRODUCTION

This chapter describes the differences between earlier versions of the HP C2858A/C2859A DesignJet 650C plotters and the latest version documented in this manual. Versions are iden- tified by their serial number and the date codes on their printed-circuit assemblies (PCAs). Introduction .9-1 History of Assemblies by Serial Number .9-2 History of Printed Circuit Assemblies (PCAs) .9-3 Product History 9-1, HISTORY OF ASSEMBLIES BY SERIAL NUMBER C2858A and C2859A plotters use a serial number format as follows: USAxxyyyyy where; US indicates country of manufacture, A indicates the plotter revision level, xx indi- cates the month (1-9, A, B, C) and week (1-4) of manufacture, and the remaining digits (y-y) are the individual sequential numbers of the plotters as they are manufactured. Table 9-1 is a quick-reference table that lists, by plotter serial number, the assemblies that differ from those documented in this manual. Also referenced are Item Numbers under which these differences are described in this chapter. Table 9-1. Assembly Reference by Serial Number Prefix Serial Number Prefix Assemblies Items NO CHANGES Table 9-2 lists the assemblies, other than PCAs, under each item in this chapter. Table 9-2. Item Description Item Assemblies NO CHANGES 9-2 Product History, HISTORY OF PRINTED-CIRCUIT ASSEMBLIES Hewlett-Packard’s PCAs have three major identification features: Part Number. PCAs having the same part number are directly interchangeable. If a PCA is revised in any way that makes it non-interchangeable with previously issued PCAs of a particular part number, a new part number is assigned to the revised PCA. Revision Letter. This letter identifies the most recent revision to the etched circuit pattern. The original issue is identified with the letter A. If the master art work for a printed circuit board is revised in order to alter performance or manufacture, the revision letter is changed to the next letter in the alphabetical sequence. Assembly Date Code. The date code on the PCA is a four-digit number which identifies the assembly level by date code. The PCA date code is changed when a component or component part number is changed which alters the performance of the PCA. The first two digits represent the last two digits of the current year and are derived by subtracting 60 from the current year; the last two digits represent the week in that year, ie: 3302 = second week in 1993. Any digits following a hyphen in the date code represent the division that manufactured the printed circuit assembly. Table 9-3 is a quick-reference table that lists PCAs by part number and date code. Listed next to the part number and date code of the PCAs are the Items located in this chapter that de- scribe the differences between the PCA in question and the level of that PCA described in the main body of this manual.
