Chapter 1 Product Information Technology Update

Modular Ink Delivery System A modular ink delivery system is the separation of ink cartridges and printheads into individual, single-color components. Traditional inkjet printers use one black and one tri- color ink cartridge, each with integrated printheads. HP's modular ink delivery system features four separate ink cartridges-one for each primary printing color-and four corresponding long-life printheads, with tubes connecting the components. Including the standard and high-capacity black ink cartridges, there are actually nine consumables, with only eight used in the printer at one time. Product Information 1-1,

Technology Update

How It Works By separating the ink cartridge from the printheads, a modular ink delivery system allows the ink supply to remain in a permanent, fixed position. The printheads remain attached to the carriage and move back and forth, delivering ink to the page as the paper advances through the printer. Each printhead and ink cartridge is embedded with a tiny memory device called a smart chip that recognizes and stores the unique operating characteristics of the component to create a totally integrated printing system that ensures consistent, high-quality printing at the lowest cost available. A unique pressurization system maintains a constant supply of ink to the printheads. Smart chips monitor the amount of ink used by counting every drop that passes through each printhead. When the smart chips sense more ink is needed to maintain continuous printing, a plunger in each cartridge temporarily pressurizes the cartridges to deliver more ink to the printheads. With the modular ink delivery system, ink supply is instantly replenished, even at top speeds. The new, individually replaceable printheads are designed for long life and each should print 12,000 pages in black, 24,000 pages in color. As a result, you'll go through many ink cartridges before the corresponding printhead will need replacement. With their modular design, ink cartridges contain twice the ink supply of current HP cartridges, so you'll also get longer lasting cartridges. When a component approaches the end of its print life, the smart chip notifies the user through on-screen messages so a replacement can be purchased prior to the part expiring. By separating the printheads and ink cartridges, you only replace the component that is no longer usable. Printheads can be replaced one at a time without the need for costly or extensive servicing and aren't discarded when the ink is expended. HP printheads also use a wet wiping system to eliminate nozzle clogging that plagues other permanent printhead designs. Component replacement is easy. Simply pull out the used part and snap in a replacement. 1 - 2 Product Information,

Technology Update

The Benefits Cuts up to 30 percent off the printing costs of other methods § Modular design means only the component that is no longer useful is replaced. § Longer-life printheads and higher-capacity ink cartridges means less frequent replacement. Achieves color laser speed in a personal desktop printer § Printheads have 304 nozzles apiece (1,216 total, the most in the industry) resulting in faster print speeds. § Prints in 1/2-inch swath as opposed to the 1/5- or 1/3-inch swaths of integrated print cartridges. § Ink cartridge pressurization system keeps constant flow of ink to printhead. Smart chips store component information and alert user to low-ink, ink-out and printhead failure status. Product Information 1-3,

Specifications

The Centronics Parallel Cable has only 8 data lines, 5 status lines, 4 ground lines and ground connections between the host PC and the peripheral. Each of the signal lines has a corresponding bit position in a memory address (register) in the host where data is read or written. Sending data to the printer follows the sequence below: § Host places data in Data Out register § Host sends pulse on Strobe line § Printer sends pulse on Busy in response to pulse on Strobe § Printer reads data on Data Out lines § Printer sends pulse on ACK (Acknowledge) line after data is read This method of data transfer is also known as the Compatibility mode and the transfer rate of data is slow. The printer while operating in compatibility mode is capable of indicating limited printer error feedback to the host computer. Such feedback includes: § Paper jam § Out of paper § Printer on or off line § Time out Product Information 1-11,

customer can order the HP IEEE 124 Compliant Parallel Interface Cable C2950A (2 meters) or C2951A (3 meters). See Ordering Parts in Chapter 12 for ordering information. PIN NUMBER PIN ID DESCRIPTION 1 HostClk Used in a closed-loop handshake with PeriphAck to transfer data or address information from the host to the peripheral device. 2 - 9 AD1 - AD8 Host to peripheral device or peripheral device to host address or data. Data 1 is the least significant bit (bit 0). 10 PeriphClk Used in a closed-loop handshake with HostAck (nAutoFd) to transfer data from the peripheral device to host. 11 PeriphAck The peripheral uses this signal for flow control in the forward direction. PheriphAck also provides a ninth data bit to determine whether command or data information is present on the data signals in the reverse direction. 12 nAckReverse The peripheral drives this signal low to acknowledge nReverseRequest. The host relies upon nAckReverse to determine when it is permitted to drive the data signals. 13 Xflag This is used by the peripheral device to reply to the requested extensibility byte during the negotiation phase. 14 HostAck The host drives this signal for flow control in the reverse direction. It is used in an interlocked handshake with PeriphClk. Host Ack also provides a ninth data bit used to determine whether command or data information is present on the data signals in the forward direction. 16 Logic Ground Logic board ground. 17 Chassis Ground Chassis Ground. 18 Peripheral Logic High This signal is used to provide +5V high logic. 19-30 Ground These pins are tied to signal ground 31 nReverseRequest This signal is driven low to place the channel in the reverse direction. While in ECP mode, the peripheral is only allowed to driver the bi-directional data signals when nReverseRequest is low and 1284 Active is high. 1 - 1 2 Product Information, 32 nPeriphRequest During ECP mode the peripheral may drive this pin low to request communications with the host. This request merely “hints” to the host; the host has ultimate control over the transfer direction. This signal provides a mechanism for peer-to-peer communication. This signal is valid in the forward and reverse directions. 36 1284 Active Driven high by host while in ECP mode. Set low by the host to terminate ECP mode and return the link to the Centronics (uni-directional) mode The 1284 compliant cable supports the ECP (Extended Capabilities Port) mode in the transfer of data. The ECP protocol includes a series of protocols that differ from standard Centronics parallel port operation. These additional signaling methods allow the host and peripheral to negotiate any of faster transfer modes (e.g. DMA, FIFO and RLE decompression). The protocol is hardware driven and the performance is limited by the ISA bus bandwidth. The primary advantage is that once data transfer is negotiated, data can flow without the need of an acknowledge or a return status signal. This can result in a transfer rate of up to 10 times faster than that of the compatibility mode that the Centronics parallel cable supports. To transfer data, the host first goes through a negotiation phase, which allows the host and peripheral to select a mutually-supported communications mode. During the negotiation phase, the host indicates which communication mode and options it would like to use via the Extensibility Request Value. If the peripheral device does not support the requested mode or options, it sets the Extensibility Flag low and the interface returns to Compatibility Mode. Product Information 1-13,

Hewlett-Packard Limited Warranty Statement HP Product Duration of Limited Warranty Software 1 year Print Cartridges 90 days Printer 1 year Printheads 1 year Extent of Limited Warranty 1. Hewlett-Packard (HP) warrants to the end user customer that HP products will be free from defects in materials and workmanship, for a specified time after the date of purchase by the customer. The duration of this limited warranty is stated above. Certain additional conditions and limitations of HP’s warranty are stated in the user’s guide. Those conditions and limitations include: a. For software products, the warranty applies only to the media upon which the product is recorded; and b. HP does not warrant the operation of any product to be uninterrupted or error free. 2. HP’s limited warranty covers only those defects which arise as a result of normal use of the product, and do not apply to any: a. Improper or inadequate maintenance; b. Software or interfacing not supplied by HP; c. Unauthorized modification or misuse; d. Operation outside the product’s environment specifications, including duty cycle abuse or use of a mechanical switch-box without a designated surge protector; e. Use of non-supported printing media or memory boards; or f. Improper site preparation or maintenance. 3. For HP printer products, the use of a non-HP print cartridge or a refilled print cartridge does not affect either the warranty to the customer or any HP support contract with the customer; print cartridge includes both toner cartridges and ink cartridges. However, if printer failure or damage is attributable to the use of a non- HP or refilled print cartridge, HP will charge its standard time and materials charges to service the printer for the particular failure or damage. 4. If any software media product or print cartridge product proves defective during the applicable warranty period, and if the product is covered by HP’s warranty, the customer shall return the product for replacement. Product Information 1-37, 5. If HP receives, during the applicable warranty period, notice of a defect in a hardware product which is covered by HP’s warranty, HP shall either repair or replace the product, at its option. Any replacement product may be either new or like-new, provided that it has functionality at least equal to that of the product being replaced. 6. If HP is unable to repair or replace, as applicable, a defective product which is covered by HP’s warranty, HP shall within a reasonable time after being notified of the defect, refund the purchase price for the product, provided the customer returns the product. 7. The warranty is valid in any country where this product is distributed by Hewlett- Packard. Contracts for additional services such as on-site service are available from any authorized HP service facility in countries where this product is distributed by HP or an authorized importer. 8. This limited Warranty Statement gives the customer specific legal rights. The customer may also have other legal rights which vary from state to state in the United States, from province to province in Canada, and from country to country elsewhere in the world. Limitations of Warranty 1. NEITHER HP NOR ANY OF ITS THIRD PARTY SUPPLIERS MAKES ANY OTHER WARRANTY OF ANY KIND, WHETHER EXPRESS OR IMPLIED, WITH RESPECT TO HP PRODUCTS. HP AND ITS THIRD PARTY SUPPLIES SPECIFICALLY DISCLAIM THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. 2. To the extent that this Limited Warranty Statement is inconsistent with the law of the locality where the customer uses the HP product, this Limited Warranty Statement shall be deemed modified to be consistent with such local law. Under such local law, certain limitations of this Limited Warranty Statement may not apply to the customer. For example, some states in the United States, as well as some governments outside the United States (including provinces in Canada), may: a. Preclude the disclaimers and limitations in this Warranty Statement from limiting the statutory rights of a customer (e.g. Australia and the United Kingdom); b. Otherwise restrict the ability of a manufacturer to make such disclaimers or impose such limitations; or c. Grant the customer additional warranty rights, specify the duration of implied warranties which the manufacturer cannot disclaim, or not allow limitations on how long an implied warranty lasts. 3. To the extent allowed by local law, the remedies provided in this Warranty Statement are the customer’s sole and exclusive remedies. 1 - 3 8 Product Information, Limitations of Liability 1. EXCEPT FOR THE OBLIGATIONS SPECIFICALLY SET FORTH IN THIS WARRANTY STATEMENT, IN NO EVENT SHALL HP BE LIABLE FOR ANY DIRECT, INCIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER BASED ON CONTRACT, TORT, OR ANY OTHER LEGAL THEORY AND WHETHER ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Print Quality Menu Item Value Explanation PRINT QUALITY= NORMAL NORMAL: Normal mode delivers high NORMAL ECONOFAST quality output and is the recommended setting BEST for speed and quality. Normal mode is the default setting for most paper types. ECONOFAST: Draft quality printing. EconoFast mode prints faster than Normal mode and delivers comparable output. Using EconoFast will also cut down on the frequency of replacing your ink cartridges because it uses less ink. EconoFast printing is available only when you select plain paper or transparency as the paper type. BEST: High quality printing. Best mode produces the highest print quality for all paper types and eliminates the banding effect that sometimes occurs in solid areas. However, Best mode prints more slowly than Normal mode for most documents. Note 2. When printing in either Normal or Econofast mode, the printer will print bi-directionally (that is, from left to right and right to left). 3. 4. However in when printing in Best mode, the printer will print uni-directionally (that is, only from right to left). Printing in Best mode will result in slower printing, but this can solve banding problems. 2-14 Operating Overview,

Printer Diagnostic Pages

The HP2500C can test-print up to two self-diagnostic pages: the diagnostic page and extended diagnostic page. A PostScript (PS) configuration page may also be printed if the PS Personality Module has been installed. Please note that the default pick for diagnostic pages is determined by the firmware version of the printer and can not be changed. Diagnostic pages will by default always pick from Tray 2 or Tray 3 (depending on firmware rev.). Diagnostic Page The various fields on the page are as follows: § Version: firmware version of the printer. § Service ID#: born-on-date, which takes the format YYDDD, where YY indicates the year and DDD indicates the ordinal number of days in the year when the printer was first used by the customer. § Index: number of pages printed. § Built-in Bitmap Fonts: the PCL fonts that reside in the printer. Operating Overview 2-33,

Printer Diagnostic Pages

Printhead Info § Pages Printed (approximate): this takes the formatBCMY, and shows how many pages have been printed by each individual printhead. § Nozzles Disabled (<3 OK): this shows, if any, the number of printhead nozzles that are not functioning properly. If any of the nozzles are disabled, the problem may be rectified by trying any of the cleaning procedures. Disabled nozzles may also indicate printhead end-of-life. § Printhead Status: this shows the condition of each printhead. When the indicating line moves into the red zone, it means that the printhead has reached the end of its useful service life. Cartridge § Pages Printed (approximate): this takes the formatBCMY, and shows how many pages have been printed by each individual cartridge. § Ink Cartridge Level: this shows the amount of ink in each cartridge. When the indicating line moves into the red zone, it means that the ink in the cartridge is going to finish soon. 2-34 Operating Overview,

Chapter 3 Loading Paper and Paper Behavior Loading the Trays

Overview The HP 2500C/CM Printer has 3 paper trays and 1 Rear Manual Feed. Tray 1 - This tray is used as a bypass tray, and holds up to 10 sheets of paper. This tray should be used for media types and sizes that are seldom used. Tray 2 - This tray holds up to 150 sheets of paper. It is recommended that you use this tray to hold commonly-used paper. Tray 3 - This tray holds up to 250 sheets of paper. It is recommended that you use this tray to hold commonly-used paper. Rear Manual Feed - The Rear Manual Feed is designed to provide a straight paper path for printing on thicker media (up to 0.3mm), such as card stock or labels, without bending. This paper path will only allow you to print on 1 sheet at a time. Loading Paper and Paper Behavior 3-1,

After sending the print job, the LCD Panel will display the message "MNL FEED LOAD [ TYPE ] [ SIZE ]" where [ TYPE ] and [ SIZE ] is the media type and size as specified in your printer driver respectively. 3. Insert the paper media into the Rear Manual Feed at the back of the printer, making sure that the edge of the sheet is aligned with the alignment mark on the left side of the slot. Wait for the printer to grip the media before releasing it. Loading Paper and Paper Behavior 3-7,

Paper Behavior

The HP 2500C has an automatic paper size sensing capability. However, paper type cannot be automatically detected and has to be manually set via the LCD menu. (The driver selections for paper tray can be: Tray1, Tray2, Tray3, Autoselect or Manual Feed.) If PAPER SIZE or TYPE as specified in a print job does not match the LCD setting or current paper size settings, the printer will respond in different manners. The following are the various cases which may be encountered : Print Job Selected Tray 2 1. The printer will check if Tray 2 has the correct Size and Type. 2. If the Type and Size are correct but there is paper media in Tray 1, the printer will prompt to remove the media from Tray 1. 3. If Tray 1 paper is not removed, all the paper from Tray 1 will be picked and ejected, followed by a load from Tray 2. 4. If the Tray 2 Size and Type of the media does not match the print job selection: i. The printer will check Size and Type settings for Tray 3. ii. If the Tray 3 settings match the print job selection, the printer will load from Tray 3. iii. If the Tray 3 settings do not match, the printer will ask the user to load the correct media Size and Type in Tray 1. 5. If Tray 2 is Out of Paper : i. The printer will check Size and Type settings for Tray 3 ii. If the Tray 3 settings match the print job selection, the printer will load from Tray 3. iii. If the Tray 3 settings do not match the printer will ask to load the correct media Size and Type in Tray 1. The same procedure applies to print jobs selecting Tray 3. 3-8 Loading Paper and Paper Behavior,

Potential Health Effects Primary Routes of Exposures Skin, eye, oral and inhalation Acute Health Hazards Skin Contact Prolonged or repeated exposure to polyethylene glycol is not likely to cause severe skin irritation. Severe response may be caused if the skin is scratched or cut. If material is encountered at higher temperature, more intense effects as well as thermal burns are possible. Skin Absorption The material is not likely to be absorbed through the skin in harmful amount during a single prolonged exposure. There is some indication that prolonged or repeated exposure of damaged skin to polyethylene glycol may result in absorption of toxic amounts. Eye Polyethylene glycol may cause slight temporary eye irritation. Oral The toxicity for a single dose is low. No hazards anticipated from ingestion incidental to industrial exposure. Inhalation Vapors are unlikely at room temperature due to the properties of polyethylene glycol. Systemic and other effects Based on the data available, repeated exposures are not likely to cause any severe adverse effects. Findings of kidney failure and death in burn patients, as well as some studies using animal burn models, suggest that polyethylene glycol may have been a factor. The use of tropical applications containing polyethylene glycol may not be appropriate in severely burned patients of individuals with impaired renal function. Polyethylene glycol did not cause cancer in long term animal studies. 5-6 Maintenance and Ink Cartridge Safety,

Chapter 6 Functional Overview Writing System

Introduction The ink transport system for the HP 2500C consists of four sub-systems as follows: § Supply Station (where the ink supply is stored) § Ink Delivery System (which transports the ink from the supply station to the printheads) § Carriage Assembly (which moves the printheads from the service station across the paper) § Service Station (which maintains the printheads between print jobs) The ink, stored in the supply station in replaceable ink cartridges, is carried by the ink delivery system to the carriage assembly and stops in the printheads. The service station cleans the printheads and collects excess ink expelled by the printheads as they are readied for use at the beginning of each printing session, and when cleaning routines are selected from the Service menu. The Service Station also caps and stores the printheads between printing sessions to prevent the printhead’s nozzles from drying out. Functional Overview 6-1,

Thermal InkJet Technology The HP printer family uses Thermal InkJet II (TIJ II) technology. The basic principle of TIJ II is to apply heat to a tiny amount of ink until it expands and is propelled through a nozzle. The first step in the process is to fill a small reservoir, known as the firing chamber, with ink. The next step is to heat the ink with a thin-film resistor layered above the firing chamber. As the ink heats up, it expands to form a bubble. The bubble continues to expand and finally "bursts". At the instant when the bubble bursts, the ink is forced through the nozzle located below the firing chamber and out onto the paper. 6-4 Functional Overview,

Writing System

Bubble collapse begins refill. As the bubble collapses, the ink in the orifices retracts, breaking off the ejected drop of ink and drawing the meniscus into the orifice. The surface tension in the deformation of the meniscus produces the suction to draw in fresh ink to refill the chamber. Meniscus settles to complete refill. This process repeats up to 12,000 times a second and creates residual heat in the resistor. A layer of silicon is placed above the resistor to cool it by conducting away the residual heat. Functional Overview 6-5,

Paper Paths and Components

Chassis The chassis structure consists of two high strength polymeric supports held together by two sheet metal tie bars (see figure below). The two tie bars are placed a distance apart to yield a high moment of inertia. This results in a structure of high rigidity in torsion and bending. Besides structural purposes, the lower tie bar is used to mount the paper trough and the higher tie bar to hold the upper paper guides. An open structure like this can accommodate flexibility in designing for removable trough from the back. Moreover, the modularity allows ease of assembly at the top level; the carriage system is mounted at the top and the dual bin is mounted at the bottom on the two supports. The primary datum of the system is on the supports, thus minimizing the tolerance stack- up on critical subsystems like the drive, input and carriage. Polymeric material of the supports allows flexibility in complex designs to support these subsystems.Right support Upper tie bar Lower tie bar Left support Chassis Structure 6-6 Functional Overview,

Output Management Output Mechanism Schematic holder-starwheel(main) holder-starwheel(sec) carriage chassis starwheel(secondary) starwheel(main) cockle rib output shaft platen ramp separator Star-wheels There are two rows of star-wheels, main and secondary. The main row contains ten sets of active starwheels (each set consists of 2 starwheels) and two passive starwheels . Active starwheels are preloaded by starwheel springs and are driven by output roller. The linear speed of starwheels is 2 % greater than that of drive roller thus creating paper stiffness to maintain the critical parameter pps distance. Also, once the media leaves the outpinch rollers, these starwheels become the only driving force to eject the media to the output tray. Two passive starwheels (not shown in figure) are provided to control A/A4 media shape such a way that the bow shape created by ramp does not propagate into the print zone. There are four sets of secondary starwheels in between the main row starwheels and cockle ribs. Locating the outer profile of these starwheels at the tangential line connecting the main row active starwheels and cockle rib tip make sure that media is not lifted above the tangential line and also the media does not touch the chassis once it leaves outpinch roller after printing.

Star-wheel Spring It is a coil spring type loaded transversely. The objective is that the spring force is high enough to eject all the media supported and is low enough not to produce any star-wheel track marks or minimum marks within the acceptable level. Spring force (@ span 14.2 mm and deflection 1.5 mm) : 19 gm Deflection in assembled condition : 1.5 mm Allows additional deflection to accommodate paper thickness : 1.2 mm and other unusual operation (example: paper jam removal) Output Mechanism Output Ramps Four sets of ramps are used to support different media from Post Cards to Super B-size media during printing . This creates a bow-shape especially for media sizes B5,A, Letter, Legal by stressing the media thereby increasing the drying time to avoid smearing on the previous printed media. Ramp Profile The ramp has a slope in two stages with respect to horizontal or paper axis to increase the resistance gradually. 1st stage angle :21° 2nd stage angle :30° Ramp also has slope in front direction which helps media to form bow-shape. Ramp edges have been curved to reduce friction with mating platen surface. 6-8 Functional Overview,

Ramp Drive Ramps are driven by Stepper motor (Bi-polar) through gear train. Each ramp has rack tooth profile and individual pinion fitted in a shaft engages with rack tooth. The ramps can be moved in both directions (extended and withdrawn). Ramps are stopped in both directions mechanically by Platen surfaces. In the forward direction, ramps are stopped by stopper (snapped to it ) hitting the Platen surface. In the reverse direction, projection in the ramp hits the Platen surface. In reverse direction, projection in the ramp hits the Platen surface. Output roller Platen Stopper Ramp (on platen) Stopper Ramp stopper (on platen) Gear-ramp Ramp slipping mechanism Slipping arrangement is provided for the ramps. During Printer initialization as well as during resetting after Elec. Power disruption we need to bring the ramps back to their home position (withdrawn condition) as we will not know their current position. To achieve this ramps have to be overrun but at the same time the drive to the ramps should be cut-off once they have reached their home position. Axially loaded compression spring provides frictional force (400gm) to the slip-gear which transmits motion from the drive shaft to the ramp-gear. In case the resistance force from the ramps increases (due to stoppage) more than 400 gms,the spring compresses further and thereby slip-gear starts slipping. Force required to stall/ hold the ramp for slipping : 175-275 gm (measured on the face of the ramp i.e; opposite to the direction of ramp movement ) 6-10 Functional Overview,

Output Reverse Control Primary bin media pick is initiated by reverse motion of LF motor for a specified (small) angle. As our output drive is connected directly to LF motor , star wheels tend to rotate in reverse direction . This pulls back the media which is to be ejected to the print zone which may cause jamming. (Note: Media ejection is done simultaneously along with Pick to increase throughput). Hence we need a mechanism which should be able to disengage output star wheel drive during the reversal of LF motor. This is taken care by introducing Rocking gear as a part of the output drive . Rock gear engages with its mating gear only when LF motor rotates in forward direction and disengages in reverse direction. Rock gear is mounted on the arm-rocker which is stopped in defined positions in both directions by Left-support wall. Arm-rocker disengagement angle is 20°.

Output Tray Assembly Output stack sensor Output stack height has to be sensed to indicate the user that output tray is full so that user can clear the printed media. Moreover , if the output stack height reaches beyond certain limit (31mm from the seperator base to the ramp front side bottom end) it may affect the ramp extension which inturn will disturb output media drying time / holding distance. 6-14 Functional Overview,

Paper Paths and Components

Output stack sensing is based on fixed field proximity sensing using two LEDs side by side.These LEDs have both light source emitters as well as receivers. In short, it is based on the concept of fixed distance sensing and ignoring any objects that lie beyond their sensing range regardless of object surface reflectivity e.g. plain paper vs. glossy paper. (But Transparencies will affect the sensing distance, they are detected earlier by 8mm) Sensor is mounted on the carriage wall directly on top of the BOF of media (which is approx. 10mm). As BOF is the non-printed area, this is used as the reflecting surface for the light so that the variation in colour/text content of the output media does not have any influence. Fixed field sensors compare the amount of reflected light that is seen by two differently aimed receiver optical elements. A target is recognised as long as the amount of light reaching receiver seen by one receiver is greater than other. Distance of sensing( from the bottom of the sensor to paper full level) = 35mm Functional Overview 6-15,

Linefeed Accuracy A closed loop drive system was used to ensure good positional accuracy of the transmission system. This involved the use of a rotary encoder disc mounted on the drive roller shaft in conjunction with a three gears gear-train design. The mounting of the encoder disc directly on the drive shaft helps to eliminate gear and motor errors and at the same time offer direct feedback on the position of the drive roller shaft. However, errors due to encoder disc eccentricity, drive roller run-out and media-roller interface will still be present. The encoder disc is a rotary disc made from Kodak LPF7 film. A total of 1440 counts were printed on the disc at an optical diameter of 58.2125 mm. The count to count spacing is 200 LPI. This spacing translate into a linear movement of 1/300 inch on the circumference of the ∅38.808 mm drive roller. 6-16 Functional Overview,

Paper Paths and Components

To achieve linefeed of less than 1/300 inch, the spacing between counts will have to be extrapolated with the help of the HP HEDS 9730 series incremental encoder module. With this combination, the smallest linefeed increment of 1/2400 inch will be possible. Due to torque and throughput consideration, a gear ratio of 15 : 1 is used. This is achieved in two stages of 3.75 and 4. Spur gears with AGMA quality standard 10 were selected to ensure good accuracy and to help minimize servo-control problems. Also, pressure angle of 14.5° was used to reduce transmission noise. Functional Overview 6-17,

This design will clear the back of the printer for the user to removed any media that are jammed inside the printer ( For details on removable trough, refer to Replacement of Paper Trough (Chapter 9)) The PCA will always be in the upright position, as shown in figure A . When there is a paper jam and need to remove the media from the back of the printer, then the user will need to unlock the locking lever and lower the PCA. The PCA will swing down 90° and lie flat as shown in figure B.

Modular PCA The PCA is mounted on a metal ground plate and is cased up with plastic case as shown in figure C. This allowed it to ship separately from the printer itself and assemble at the DC. By doing this, the printer can be configured differently to suit the market demand by connecting the printer with different type of PCA module. The overall size of this module is 185mm x 470mm x 95mm. Brackets are provided on the printer to mount the PCA module. The module is fastened to the bracket with 4xM3 screws as shown in figure D. 95.0

A DC motor is used to supply power to provide the pick force (µN, N=mg) to drive the top media sheet(s) against the separation surface in front of the tray. The angle of the separation surface with respect to the horizontal is in such that it ensures only one sheet of media is fed through. The media is fed continuously until it reaches the set of pinch rollers at the drive roller, before the drive roller takes over the driving force. Functional Overview 6-21,

Dual Bin Skew Correction Method The TOF skew for media from dual bin is bettered by the dual bin skew correction to its required specifications. The media from the dual bin tray is fed by the dual bin pick roller until it hits the first roll of in-pinch rollers, which is stationary at that moment. The over feeding of the media will cause the media top edge to align perpendicularly to the pinch rollers and corrects itself. The drive roller takes over the drive the media into the print zone. 6-22 Functional Overview,

It supports the whole weight of the primary paper path mechanism and writing system from the top, provide mounting for the swivel PCA from the back, encapsulates the 100V power supply on the right, and provides sliding surface and datum surface for the dual bin tray at the middle. The x-y datum for the primary print mechanism on top is provided by two datum pins at the structure and its z datum is given by the height of the dual bin structure. The dual bin structure also provides datum pins for the swivel PCA and the power supply. There are two bias springs which pushes the dual bin tray to the right against the datum rail. This will determine the right margin for the media printed. Two screw bosses which provides mounting location for the primary print units also serve as the datum pins for the dual bin pick and feed mechanism, the dual bin pivot arm module, which is mounted underneath the sheet metal dual bin beam top. The material requirement for the dual bin structure has to meet grade V5 (Noryl) or better as it encapsulates the high voltage power supply module.

HP 2500C Electronics

Motor Control Overview There are four main motors in the HP 2500C printer : the Carriage Motor, the IDS Motor, the Line Feed motor and the Dual Bin motor. Additionally, there are two Service Station Motors and one Output Ramp Motor. The following diagram shows the control hierarchy of the motors in the HP 2500C: Functional Overview 6-25,

Firmware

Firmware is the collective medium comprising of the computer, the printer mechanism and the key panel that enables all three components to communicate and interact. The printer by itself does not independent capability to process printing data (such as print mode and byte stream), obtaining this data from the software-driven printer driver. The printer is thus dependent on the host for the processing and sending of job data. The HP 2500C, however, supports full duplex (bi-directional) printing and is able to give extensive feedback on print status to the host computer. This is an overview of the firmware, summarizing the flow of data: (firmware data flow diagram) The firmware operates on three layers: the physical layer, the data link layer and the application layer. 6-26 Functional Overview,

Firmware

Physical Layer On the physical layer, the firmware performs the following functions : § It supports IEEE 1284 (bi-directional) compatibility in Forward mode. § It is able to return extended status reports to the host computer in Nibble mode. § It identifies the Device ID. § It negotiates between various modes. Data Link Layer On the data link layer, the firmware will perform : § Support channeling of commands, pacing, status, device ID and print data to their respective destination devices. § Perform limited frame checking and recovery. Application Layer On the application layer, the firmware’s function is to : § Control the printing, media and pen. § Configure communication status. § Provide synchronized or asynchronized status reports. § Perform limited print mechanism error recovery. § Perform low-level device commands (e.g. change ID). Functional Overview 6-27,

Firmware

Interface with mechanism The following diagram shows the interface between the firmware and the hardware : (hardware-firmware interface diagram) § Paper Motor control is an open-looped control. The firmware does not know the exact position or the size of the paper and relies on the OOPs flag to confirm the presence of paper. § Service Station control is also an open-looped control. There is no feedback to the firmware from the Service Station. § Carriage Control is a closed-loop control. The Carriage PCA is enabled by the encoder strip to read and send data back to the firmware. § Pen information is also controlled by a closed loop. The firmware is therefore able to receives printing data such as pen firing parameters, pen ID and pen temperature from the active pen. 6-28 Functional Overview,

Firmware

Interface with Key Panel The Key Panel consists of 3 buttons and 2 LEDs. The buttons allows you to perform some rudimentary interactions with the firmware. The indication of the LEDs allows you to troubleshoot any printer problems. (See Indicator Lights (Chapter 2) for more information on the LEDs). The firmware is running if there is AC power supply to the printer even if the printer LEDs are off. The LEDs will light up when data is sent to the printer or when the Power button is pressed.

Before disassembly please ensure that the proper precautions to prevent damage by electrostatic discharge (ESD) to ESD-sensitive printer components have been taken with ESD heel or wrist straps. Ensure also that the work area is similarly free of static current. § When disassembling the printer, ensure that the capacitors are fully discharged before you handle power supply components. As a precaution, switch off the printer before disconnecting it from the power socket, and wait five seconds before commencing disassembly. 7 - 2 Removal and Replacement of Parts (without Calibration),

Important Notes about Printer Components and Disassembly

The printer has been built to a modular architecture which uses one-way snap-fit technology – that is, parts are designed so that they will only fit with each other in one direction. Please exercise care and apply only the force required to remove each component, as excessive force could damage the parts. When reassembling the printer, remember to use the correct screw type when putting the components together. Removal and Replacement of Parts (without Calibration) 7-3,

Chapter 8 Troubleshooting Troubleshooting Concepts

If there is a problem with the printer, there are several steps that can be taken to trace and resolve the problem. If you get a message on the computer screen, follow the on-screen instructions. If you did not receive an error message but suspect that something may be wrong with the printer, you can check the HP Toolbox by clicking on the Troubleshooting tab, then select the appropriate section and perform any printer diagnostics as required. If the printer is not printing, examine the following for signs of abnormal operation : § key panel LEDs § printer operation § assembly operation For each symptom, there may be more than one solution possible. Using your own experience and the information provided in this chapter, you should be able to trace the problem to its source and carry out the appropriate repairs. The design of the printer, which allows you to replace and test one component at a time, should be helpful in resolving any problems. Troubleshooting 8-1,
