45% to 55%. The following guidelines should be helpful when evaluating the paper-storage environment: ■ Paper should be stored at or near room temperature. ■ The air should not be too dry or too humid (due to the hygroscopic properties of paper). ■ The best way to store an opened ream of paper is to rewrap it tightly in its moisture-proof wrapping. If the MFP environment is subject to extremes, unwrap only the amount of paper to be used during the day's operation to prevent unwanted moisture changes.
Envelopes that have double side seams Double side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style might be more likely to wrinkle. Be sure that the seam extends all the way to the corner of the envelope, as illustrated. Envelopes that have adhesive strips or flaps Envelopes that have a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives that are compatible with the heat and pressure in the MFP.
Labels CAUTION To avoid damaging the MFP, use only labels that are recommended for use in laser printers. Never print on the same sheet of labels more than once or print on a partial sheet of labels. Label construction When selecting labels, consider the quality of each component: ■ Adhesives: The adhesive material should be stable at 200°C (392°F), the MFP's fusing temperature. ■ Arrangement: Only use labels that have no exposed backing between them.
Supported types and sizes of print media The following table lists the types of media that the MFP supports.

4 Maintenance This chapter contains information about the following topics: ● Cleaning the MFP ● Calibrating the scanner ● Performing preventive maintenance ● Managing the print cartridge ● Setting the real-time clock ● Configuring and verifying an IP address ● Upgrading the firmware 55
Cleaning the MFP To maintain print quality, clean the MFP thoroughly whenever print-quality problems occur and every time you replace the print cartridge. WARNING! Avoid touching the fusing area when cleaning the MFP. It can be hot. CAUTION To avoid permanent damage to the print cartridge, do not use ammonia-based cleaners on or around the MFP except as directed. Cleaning the outside of the MFP ■ Clean the outside of the MFP if it is visibly marked.
Running the cleaning page In order for the cleaning page to work properly, print the page on copier-grade paper (not bond, heavy, or rough paper). To run the cleaning page 1 Press MENU. 2 Scroll to and touch CONFIGURE DEVICE. 3 Touch PRINT QUALITY. 4 Touch PROCESS CLEANING PAGE.
Cleaning the ADF delivery system Clean the ADF only if it is visibly marked or dirty, or if you are experiencing a decrease in copy quality (such as streaking). To clean the ADF delivery system 58 1 Open the scanner lid. 2 Locate the white, vinyl ADF backing. 3 Locate the white, vinyl calibration strips. 4 Clean the ADF backing and the calibration strips by wiping them with a clean, damp, lint-free cloth.
6 Close the scanner lid. To clean the ADF rollers You should clean the rollers in the ADF if you are experiencing misfeeds or if your originals show marks as they exit the ADF. CAUTION Clean the rollers only if you experience misfeeds or marks on the originals, and you notice dust on the rollers. Cleaning the rollers frequently could introduce dust into the device. 1 Open the scanner lid. 2 Locate the rollers near white, vinyl calibration strips.
4 Close the scanner lid. 5 Pull the release lever to open the ADF cover. 6 Locate the rollers. 7 Wipe the rollers with a clean, water-dampened, lint-free cloth. CAUTION Do not pour water directly onto the rollers. Doing so might damage the device. 60 8 Locate the separation pad. 9 Wipe the pad with a clean, water-dampened, lint-free cloth.
10 Close the ADF cover.
Calibrating the scanner Calibrate the scanner to compensate for offsets in the scanner imaging system (carriage head) for ADF and flatbed scans. Because of mechanical tolerances, the scanner's carriage head might not read the position of the image accurately. During the calibration procedure, scanner offset values are calculated and stored. The offset values are then used when producing scans so that the correct portion of the document is captured.
Performing preventive maintenance The MFP requires periodic maintenance to maintain optimum performance. A control-panel message alerts you when it is time to purchase the preventive maintenance kits. Separate maintenance procedures are required for the printer-portion of the MFP and for the ADF. Printer preventive maintenance You should replace certain parts when the PERFORM PRINTER MAINTENANCE message appears on the control-panel display.
The ADF maintenance kit After feeding 85,500 pages through the ADF, the MFP alerts you to order a document feeder kit. This message appears approximately one month before the kit needs to be replaced. Order a new kit when this message appears. After feeding 90,000 pages through the ADF, a REPLACE DOCUMENT FEEDER KIT message appears on the control-panel display. Replace the ADF maintenance kit at that time.
Managing the print cartridge This section provides information about HP print cartridges, their life expectancies, how to store them, and how to identify genuine HP supplies. Information also appears about non-HP print cartridges.
Checking the supply level You can check the supply (toner) level by using the control panel, the embedded Web server, HP Toolbox software, or HP Web Jetadmin.

Complete the following steps to update the HP Jetdirect firmware by using HP Web Jetadmin. 1 Open the HP Web Jetadmin program. 2 Open the Device Management folder in the drop-down list in the Navigation panel.
5 Theory of operation This chapter presents an overview of the relationships between major components in the MFP, and includes information about the following topics: ● Basic operation ● Formatter system ● Engine-control system ● Laser/scanner system ● Image-formation system ● Pickup, feed, and delivery system ● Scanner system 77
Basic operation All high-level MFP processes are routed through the formatter, which stores font information, processes the print image, and communicates with the host computer.
Sequence of operation (scanner) Period (sequence) Description Power on During this time, the scanner motors rotate, the MFP checks the status of all the sensors, the scanner lamp is illuminated, the optical scan head moves from its home position, the scanner calibrates, and then the optical scan head returns to its home position. Initialization The period of time after the initial power-on sequence and before the MFP is ready to scan or copy.
Formatter system The formatter is responsible for the following procedures: ■ Controlling Sleep mode ■ Receiving and processing print data from the various MFP interfaces ■ Monitoring control-panel functions and relaying MFP-status information (through the control panel and the network or the bidirectional interface) ■ Developing and coordinating data placement and timing with the dc controller PCA ■ Storing font information ■ Communicating with the host computer through the network or the bidire
NOTE The REt settings that are sent from software programs or printer drivers override the control-panel settings. EconoMode The EconoMode setting uses up to 50% less toner than standard mode printing by reducing the dot density. However, using EconoMode does not extend the life of print-cartridge components. EconoMode, which can be thought of as “draft mode,” can be selected from the control panel (PRINT QUALITY menu) and through some software programs and printer drivers. The default setting is OFF.
Flash memory Two flash memory slots are available for storing forms, fonts, and signatures. Firmware flash memory card The firmware is contained on a flash memory card on the formatter. Do not remove this flash memory card. A remote firmware upgrade process is available, which overwrites the firmware on the flash memory card. Nonvolatile memory The MFP uses nonvolatile memory (NVRAM) to store I/O and print-environment-configuration information.
Scanner interface The formatter receives data from the scanner to produce copies and to send scanned data in e-mail format.
Engine-control system The control system consists of three PCAs: the power supply PCA, the power-factor correction PCA, and the dc controller PCA. This system controls the laser/scanner, image-formation, and pickup-andfeed systems. The microprocessor on the dc controller PCA controls the operating sequence of the printer. DC controller PCA The dc controller PCA controls the operation of the MFP and its components.
Figure 5-1 DC controller PCA block diagram Engine-control system 85
Motors and fans The MFP print engine has 10 motors: two brushless dc motors, one dc motor that has brushes, four fan motors, and three stepping motors. The MFP print engine also has four cooling fans. Table 5-1 Print-engine motors describes the function of each motor, and Table 5-2 Print-engine fans describes the function of each fan.
Ambient-temperature detection The MFP contains a sensor that measures the air temperature of the surrounding environment. The MFP automatically adjusts the temperature settings in the fuser to adjust for changes in the ambient temperature. Engine power supply circuit The engine power supply consists of the fuser-control circuit, the high-voltage circuit, and the lowvoltage circuit.
Fuser control The fuser-control circuit controls the fuser components. The two fuser heaters provide the high temperatures that permanently bond the toner to the media. The fuser thermistor monitors the fuser temperatures. The thermal switch detects abnormally high fuser temperatures and interrupts the supply of voltage to the fuser if the temperature is determined to be too high.
Fuser over-temperature protection To protect the fuser from excessive temperatures, the MFP has the following three protective functions: ■ The CPU monitors the voltage of the thermistor. If the fuser temperature reaches 240º C (464º F) or higher, the CPU turns off the relay (RL101) to interrupt the power to the fusing heater.
Figure 5-4 Fuser circuit 90 5 Theory of operation
High-voltage power supply The high-voltage circuit produces the voltage biases that are applied to the primary charging roller, the developing cylinder, the transfer charging roller, the fuser sleeve, and the pressure roller. Figure 5-5 High-voltage power supply circuit The primary charging voltage (bias) applies a uniform negative charge to the photosensitive drum in the print cartridge. Two types of primary charging bias are used: the primary charging dc negative voltage and the primary charging ac bias.
electrostatic image on the primary charged photosensitive drum. See Image-formation system. The electrostatic image cannot be seen until toner is deposited on the drum. The developing voltage (bias) causes the toner to adhere to the electrostatic image that the laser/ scanner assembly created on the photosensitive drum. Two types of developing biases are used: the developing dc negative bias and the developing ac bias. The high-voltage circuit on the power supply generates both biases.
Figure 5-6 Low-voltage power supply circuit Engine-control system 93
Overcurrent/overvoltage protection If a short-circuit or other problem on the load side causes an excessive current flow or generates abnormal voltage, the overcurrent/overvoltage protection systems automatically cut off the output voltage to protect the power supply circuit. If the overcurrent or overvoltage protection system are activated and the power supply circuit does not generate dc voltage, it is necessary to turn the power off, correct the problem, and then turn the MFP on again.
Laser/scanner system The laser/scanner produces the latent electrostatic image on the photosensitive drum in the print cartridge. The main components of the laser/scanner assembly are the laser driver PCA, the scanner motor, various mirrors, and the focusing lenses. Figure 5-7 Laser/scanner assembly The laser scanner uses two laser diodes to scan two lines simultaneously, producing high-speed laser scanning.
photosensitive drum. The modulated laser beams generate the latent electrostatic image on the photosensitive drum according to the image data signals that are received from the dc controller PCA. Laser/scanner control The laser/scanner-control circuit on the laser driver PCA turns the laser diodes on and off according to image-data signals that the dc controller PCA sends.
Figure 5-8 Laser-control-circuit block diagram Laser-emission control simply turns the laser diodes on and off. Automatic power control limits the amount of light that the laser diodes emit. Horizontal-synchronization control determines the starting position for the horizontal direction of the image. Image-mask control prevents laser beams from striking the non-imaging areas of the drum, which is approximately 5 mm (0.2 inch) along the vertical edges and 8 mm (0.3 inch) at the top and bottom.
Image-formation system The image-formation system consists of the print cartridge, transfer-charging roller, and fuser. When the formatter sends a print command, the engine controller drives the main motor to rotate the photosensitive drum, primary-charging roller, developing cylinder, transfer-charging roller, and pressure roller. The primary charging roller applies a uniform negative charge to the photosensitive drum surface.
Print cartridge The print cartridge contains the primary-charging roller, photosensitive drum, and developing cylinder. The print cartridge has built-in memory that records the number of rotations and the toner level. This information is passed to the dc controller, which sends an alert when the remaining printcartridge life reaches a low threshold. Cartridge memory The cartridge memory is EEPROM built into the cartridge, so that the MFP can detect the cartridge conditions.
Writing timing ■ When printing is completed ■ When the dc controller PCA receives a command from the formatter The memory data that the memory controller sends also contains the status of any error that has occurred during the read/write operation. When the error status is sent, the dc controller PCA makes up to four attempts to read the operation.
4 Pre-transfer—The pre-transfer roller applies bias to prevent toner on the photosensitive drum from adhering to the pre-transfer upper guide. 5 Transfer—During the transfer process, the toner image on the drum surface is transferred to the paper. The transfer charging roller applies a positive charge to the back of the paper and causes the negatively charged toner on the drum surface to be attracted to the paper. After separation, the drum is cleaned and conditioned for the next image.
Pickup, feed, and delivery system The pickup-and-feed system consists of various rollers that the printer motors drive. The MFP uses tray 1 (the manual feeding tray) and a cassette in tray 2 as media sources. The printed media is delivered to the output device that is installed. The output device can be the standard output bin, the 3-bin mailbox, or the stapler/stacker. Only one output device can be installed. Three additional 500sheet feeders can be added to the MFP.
Figure 5-12 Motor, clutch, and solenoid locations Pickup, feed, and delivery system 103
Figure 5-13 Sensor and switch locations The pickup, feed, and delivery system is divided into two parts: 104 ■ The pickup and feed block contains the paper path from each tray and stops at the fuser entrance. ■ The fusing/reversing/delivery block contains the paper path from the fuser entrance to the output device.
Figure 5-14 Pickup, feed, and delivery system Pickup-and-feed block The following functions occur in the pickup-and-feed block: ■ Detecting media presence ■ Detecting media size ■ Detecting when media enters the paper path from the trays ■ Lifting the tray 2 paper plate ■ Preventing multifeeds ■ Adjusting the distance between pages ■ Correcting page skew Pickup, feed, and delivery system 105
Printing from tray 1 The tray 1 paper sensor (PS105) detects the presence of media in tray 1. When the dc controller PCA receives the print command, the printer starts the initial rotation phase, which consists of the main motor warm-up, scanner motor warm-up, high-voltage control sequence, and fuser warm-up. When the initial rotation phase ends, the tray 1 pickup solenoid (SL102) is activated. The cam rotates, the paper-tray lifter rises, and the media comes in contact with the tray 1 pickup roller.
Printing from tray 2 When the dc controller PCA receives print command, the main motor (M101) and scanner motor start their rotation. When the main motor reaches its prescribed speed, the feed-roller clutch (CL101) and tray 2 pickup solenoid (SL101) are activated. (The main motor rotation drives the tray 2 pickup roller, tray 2 feed roller, tray 2 separation roller, and paper-feed rollers.) The pickup solenoid activates the tray 2 pickup roller, which rotates once and picks up the media in the tray.
Media-size detection The MFP has three media-size detection systems: ■ Cassette (tray 2) media-size detection ■ Media-length detection ■ Media-width detection Cassette media-size detection The media-size detection switch (SW102) has two functions: it detects the presence of the cassette, and it detects the size of the media that is loaded in the cassette. This switch has upper, middle, and lower components that act together to detect the cassette presence and the media size.
the pickup roller to swing down, and the pickup roller contacts the surface of the paper stack. One sheet of media is fed into the MFP.
Lifter-driver operation The lifter driver keeps the media stack surface at a specific level in order to have a stabilized pickup operation regardless of the size of the media in the tray 2 cassette. The dc controller PCA operates the lifter-driver motor (M103) for 30 milliseconds. The motor stops when the paper-stack-position sensor (PS107) detects the media.
Distance-between-pages adjustment When a multiple-page print job is sent, the dc controller uses the pre-feed sensor (PS102) to maintain a uniform distance between the pages. If the distance between pages is too small or if the pages overlap, the dc controller turns off the feed clutch (CL101) and stops the next sheet of paper. After a specified time, the dc controller turns the clutch on to allow the paper-feed process to continue.
Media-skew prevention The MFP uses a registration shutter on the registration assembly to prevent skewed media from entering the MFP. When the leading edge of the skewed media contacts the registration shutter, the shutter does not open. The feed roller continues to rotate and the media begins to sag. When the entire leading edge comes in full contact with the shutter, the media skew is corrected and the registration shutter opens. When the shutter opens, the media can continue into the printer paper path.
Figure 5-21 Media sags until the entire leading edge contacts the shutter Figure 5-22 Skew is corrected, and the shutter opens Pickup, feed, and delivery system 113
Feed-speed control To ensure that the toner fuses sufficiently, the dc controller adjusts the speed at which media is fed according to the media type that the formatter specifies.
Fusing and reversing/delivery block After the toner is fused to the media, the media enters the reversing/delivery unit. The MFP can deliver the media to the output bin either face-up or face-down, depending on instructions from the formatter. To stack pages of a multiple-page print job in the correct order, the pages must be flipped over in the reversing unit before they are delivered to the output bin. This is the default setting.
Figure 5-24 Face-down delivery: media enters the reversing unit After a specified length of time, both motors stop, and the reversing motor begins rotating counterclockwise. Then, M106 drives the intermediate rollers and the delivery rollers, which guide the media into the output bin. When M106 begins rotating, the reversing-separation solenoid releases the reversing rollers, and the media begins traveling in the opposite direction.
edge of the media, SL105 turns off and the face-up deflector returns to its home position. When the paper-delivery sensor (PS109) detects the trailing edge of the media, M106 stops rotating.
Jam detection The MFP uses the following sensors to detect the presence of media and to check whether media is being fed correctly or has jammed: ■ Pre-feed sensor (PS102) ■ Top-of-page sensor (PS103) ■ Fuser-delivery sensor (PS108) ■ Paper-delivery sensor (PS109) ■ Reversing paper-sensor (PS110) ■ Reversing unit paper-jam sensor (PS111) The microprocessor on the dc controller checks for jams by timing the media as it moves past these sensors.
Fuser-delivery delay jam If the fuser-delivery sensor (PS108) does not detect the leading edge of the media within a specific period of time after the top-of-page sensor (PS103) detects the leading edge, the microprocessor on the dc controller PCA determines that a fuser-delivery delay jam has occurred. The time varies according to the length of the media. The transport process stops and a 13.XX.YY JAM message appears on the control-panel display.
Reversing stationary jam (face-down delivery only) If the reversing-paper sensor (PS110) does not detect the trailing edge of the media within a specific time period after the fuser-delivery sensor (PS108) detects the trailing edge, the microprocessor on the dc controller PCA detects that a reversing delay jam has occurred. The transport process stops and a 13.XX.YY JAM message appears on the control-panel display. For more information about jam messages, see Resolving control-panel messages.
Residual-media jam If the top-of-page sensor (PS103), the fuser-delivery sensor (PS108), or the reversing-unit jam sensor (PS111) detects the leading edge of the media at the start of initial rotation, the microprocessor on the dc controller PCA identifies a residual-media jam. In addition, if the fuser-delivery sensor (PS108) does not detect the leading edge of the media, within 2.
Printing from the 500-sheet feeder The MFP supports up to three additional 500-sheet feeders (trays 3, 4, and 5). Figure 5-27 Paper path with 500-sheet feeders installed The paper-feeder driver controls the 500-sheet feeder operation sequences. An 8-bit microprocessor in the paper-feeder driver controls the 500-sheet feeder sequences and the communication with the dc controller PCA. The paper-feeder driver drives the solenoid in response to the pickup command.
Figure 5-28 500-sheet feeder I/O block diagram 500-sheet feeder pickup and feeding The pickup and feeding processes for the 500-sheet feeder are identical to the processes for tray 2 in the print engine. See Figure 5-29 500-sheet feeder pickup and feed diagram to identify the individual switches and sensors for the 500-sheet feeder.
Figure 5-29 500-sheet feeder pickup and feed diagram 124 5 Theory of operation
Duplex-printing unit The optional duplex-printing unit (duplexer) adds another reversing sequence to print on both sides of a page. NOTE The MFP cannot print on both sides of paper that is 180 mm (7.1 inches) or shorter.
Figure 5-31 Duplex printing control Duplex printing jam detection The duplex printing unit uses the duplex-unit-pickup sensor (PS122) to detect jams. The microprocessor on the dc controller PCA determines a jam situation if the sensor indicates that paper is present at an unexpected time or that paper is not present at the expected time. The microprocessor on the dc controller PCA notifies the formatter that a jam has occurred. When a jam is detected, the transport process stops and a 13.XX.
Duplex-unit-pickup delay jam If the duplex-unit-pickup sensor (PS122) does not detect the leading edge of the paper within a specific time period after the duplex feed motor (M107) starts driving, the microprocessor on the dc controller PCA determines that a duplex-unit-pickup delay jam has occurred.
3-bin mailbox feed and delivery system When the 3-bin mailbox (MBM) is installed, it receives print media from the print engine and delivers it to one of its three bins.
Figure 5-32 3-bin mailbox operation Pickup, feed, and delivery system 129
Stacker mode When configured for stacker mode, the 3-bin mailbox fills the bottom output bin (bin 3) first and then fills the next highest bin. Figure 5-33 Media flow when using the stacker mode Mailbox mode When configured for mailbox mode, the 3-bin mailbox stacks print media in each bin as determined by the print job specifications. For example, one user might have all jobs delivered to the bottom bin, and another user might have all jobs delivered to the top bin.
Feed-stationary jam If the inlet sensor (PS1501) does not detect the trailing edge of the media within a specific time period after it detects the leading edge, the microprocessor on the MBM-driver PCA determines that a feed-stationary jam has occurred. Residual-media jam If the inlet sensor (PS1501) detects the presence of media during the initial WAIT period, the microprocessor on the MBM-driver PCA determines that a residual-media jam has occurred.
Stapler/stacker feed and delivery system When the stapler/stacker is installed, it receives print media from the print engine and delivers it to the stapler or stacks it in the output bin.
Figure 5-34 Stapler/stacker operation Pickup, feed, and delivery system 133
Staple mode When the print job specifications require stapling, the pages of the document are gathered inside the unit. A jogger aligns the pages horizontally, and a paddle aligns the pages vertically. When all pages of a job are gathered, a clamp compresses the stack and a staple is attached. After the document is stapled, the jogger guides spread apart to release the stack, and the stapled document falls into the stacker bin.
Feed-stationary jam If the inlet sensor (PS1301) does not detect the trailing edge of the media within a specific time period after it detects the leading edge, the microprocessor on the MBM-driver PCA determines that a feed-stationary jam has occurred.
Figure 5-36 Stapler unit operation 136 5 Theory of operation
Scanner system The scanner system adds copying and sending functions to the standard MFP printing function. The scanner assembly consists of an automatic document feeder (ADF) and a flatbed scanner glass surface. Original documents that are fed through the ADF are delivered to the ADF output bin, which is underneath the ADF input tray. Printed copies are delivered to the output device that is attached to the print engine. The scanner unit has built-in duplexing capability for scanning two-sided documents.
Figure 5-38 Scanner assembly electrical structure 138 5 Theory of operation
Motors and fans The scanner assembly has five motors and two fans. Three of the motors are stepping motors, which drive the components inside the scanner assembly. The remaining two motors are dc motors, which drive the two fans.
Figure 5-40 Scan carriage movement 140 5 Theory of operation
ADF feed system Pages from the original document enter the ADF from the ADF input tray. A separation roller and separation pad work together to separate the top sheet from the stack. The page passes through a set of registration rollers and two sets of feed rollers that advance the page. A set of delivery rollers delivers the page to the ADF output bin. A bin-full sensor detects when the ADF output bin is full, and stops the feed mechanism until the bin is emptied.
ADF pickup jam If the leading edge of the media did not reach the registration sensor within a specific period of time, the scanner controller PCA determines that an ADF pickup jam has occurred. ADF jam Jams can occur in three places inside the ADF: at the registration senor, read sensor, and exit sensor.

Removal and replacement strategy This chapter describes how to remove, replace, and reassemble the major assemblies of the MFP. Replacement is generally the reverse of removal. Notes are provided to assist with any difficult replacement procedures. To identify the left side and right side of the MFP, face the control panel. WARNING! Unplug the power cord from the power outlet (at the wall receptacle) before attempting to service the MFP. If you do not follow this warning, severe injury can result.
Before performing service ■ If possible, print a menu map and configuration page. See Information pages. ■ Remove all of the accessories and print media, the print cartridge, and tray 2 from the MFP. ■ Unplug the power cord from the power outlet at the wall receptacle. ■ Place the MFP on an ESD mat, if one is available. If an ESD-protected workstation is not available, discharge body static by grasping the MFP chassis before touching an ESD-sensitive component.
Screws that are used in the MFP The following table describes the screws that are used in the MFP and provides guidelines to help determine where each type of screw is used. The screws can vary in length depending on the thickness of the material that is being fastened. Always note where each type of screw is located and replace each one in its original location. NOTE When you are disassembling the MFP, place the screws into the chassis holes from which they were removed.

7 Troubleshooting In order to use the information in this chapter, you should have a basic understanding of the HP LaserJet printing process. Explanations of each mechanical assembly, the MFP systems, and the basic theory of operation are contained in chapter 5 of this manual. Do not perform any of these troubleshooting processes unless you understand the function of each MFP component.
Troubleshooting process When the MFP malfunctions or encounters an unexpected situation, information on the control panel alerts you to the situation. This section contains an initial troubleshooting checklist that helps to eliminate many possible causes of the problem. The subsequent troubleshooting flowchart helps you to diagnose the cause of the problem. The remainder of the chapter provides steps for correcting the problems that have been identified.
5 6 If the configuration page prints, check the following items. a If the page prints correctly, then the MFP hardware is working. The problem is with the computer that you are using, with the printer driver, or with the program. b If the page does not print correctly, the problem is with the MFP hardware. See Functional checks. At the computer, check to see if the print queue is stopped, paused, or set to print offline.
Troubleshooting flowchart This flowchart highlights the general processes that you can follow to quickly isolate and solve MFP hardware problems. Each row depicts a major troubleshooting step. A “yes” answer to a question allows you to proceed to the next major step. A “no” answer indicates that additional testing is needed. Proceed to the appropriate section in this chapter, and follow the instructions there.
Table 7-1 Troubleshooting flowchart 1 Is the MFP on and does a readable message appear? Power on After the control-panel display is functional, go to step 2. Yes 2 Control-panel messages 3 Event log Information pages No Does the message Ready appear on the control-panel display? Yes No If an error message appears, see Resolving control-panel messages. After the errors have been corrected, go to step 3. Open the DIAGNOSTICS menu and print an event log to see the history of errors with this MFP.
Power-on checks The basic MFP functions should start up as soon as the MFP is plugged into an electrical outlet and the power switch is pushed to the on position. If the MFP does not start, use the information in this section to isolate and solve the problem. Power-on troubleshooting overview Turn on the MFP power. If the control-panel display remains blank, random patterns appear, or asterisks remain on the display, perform power-on checks to locate the cause of the problem.
3 If necessary, replace the dc controller. See DC controller. 4 If necessary, replace the engine power supply. See Engine power supply. NOTE It is important to have the control panel functional as soon as possible in the troubleshooting process so that the control-panel display can be used to help locate MFP errors.
Control-panel messages Messages appear on the control-panel display to relay the normal status of the MFP (such as Processing Job), or an error condition (such as CLOSE TOP COVER) that needs attention. Resolving control-panel messages lists messages that require attention, or that might raise questions. Messages are listed in alphabetical order, with numeric messages at the end of the list. Not all messages are listed because some (such as Ready) are self-explanatory.

NOTE The MFP has two separate maintenance kits: one is for the print engine, and the other is for the ADF.
Usage page The usage page provides information about the page sizes and number of pages printed, copied, and sent. The usage page contains the following information: 418 1 Usage Totals: Printed indicates types of pages that have been printed, copied, and faxed; the number of singlesided pages that have been printed, copied and faxed; the number of duplexed pages that have been printed, copied and faxed (if a duplexer is installed); and the total number of pages that have been printed, copied and faxed.
PCL or PS font list Use the font lists to see which fonts are currently installed in the MFP. (The font lists also show which fonts are resident on a hard disk or flash DIMM.) The PS font list shows the PS fonts installed, and gives a sample of those fonts. The following describes the information that can be found on the PCL font list: ■ Font gives the font names and samples. ■ Pitch/Point indicates the pitch and point size of the font.
Diagnostics menu The following table shows the items that are available in the DIAGNOSTICS menu. Values that have an asterisk are the default values. Item Options Values Explanation PRINT EVENT LOG Generates a localized list of the 50 most recent entries in the error log. For each entry, the printed event log shows the error number, page count, error code, and description or personality.
Item Options Values Explanation OUTPUT BIN 3 DUPLEX ON OFF* COPIES 1* 10 50 Specify if the duplexer is included when the test is performed. Specify how many sheets of paper from the specified source are sent when the test is performed. 100 500 MANUAL SENSOR TEST COMPONENT TEST See Table 7-22 Manual sensor test letter designations for a description of the alphabetic code that is associated with each sensor. MAIN MOTOR Tests the paper path sensors and switches for correct operation.
Item Options SCANNER TESTS LOWER LAMP SENSORS ADF INPUT MOTOR ADF INPUT REVERSE FLATBED MOTOR ADF READ MOTOR ADF READ MOTOR REVERSE ADF DUPLEX SOLENOID ADF LED INDICATOR CONTROL PANEL LED'S DISPLAY BUTTONS TOUCHSCREEN Values Explanation Use this menu to diagnose potential problems with the MFP scanner. When you touch the name of each component, a message appears on the control-panel display that indicates the manner in which the component is operating.
Individual component diagnostics From the diagnostics menu, you can run tests to check the status of various components in the MFP. During many of the diagnostic tests, the MFP enters a special diagnostics mode, which allows you to send print jobs and interact with the menus. The MFP stays in this mode until you press STOP and then touch EXIT DIAGNOSTICS at the top of the DIAGNOSTICS menu. In some cases, the MFP must re-initialize after performing a component-level diagnostic test.
Manual sensor test The manual sensor test indicates the status of the sensors and switches in the MFP. On the controlpanel display, each sensor is represented by a string of letters followed by a corresponding status for each sensor. Except for the paper-size switches, a “0” next to the letter indicates that no media is present or the switch is open. A “1” indicates that media is present or the switch is closed.
Scanner tests Use the scanner tests to verify that specific components in the scanner assembly are operating correctly. For most of the components, you must observe or listen to the component in order to verify that it is functioning as stated on the control-panel display. For the scanner sensors, you must activate the sensor and watch the condition indicator on the control-panel display to see if it changes.
Service menu Authorized HP service technicians can use this menu to gain access to MFP settings that are reserved for service personnel. The service menu is protected by use of a personal identification number (PIN). When you select SERVICE from the list of menus, you are prompted to type an eightdigit PIN code. The PIN code for this MFP is 11434504. NOTE The MFP automatically exits the service menu after about 1 minute if no menu items are selected or changed.
Table 7-23 Service menu (continued) Item SCANNER SETTINGS Explanation CAUTION The SCANNER SETTINGS are used for factory adjustments and should not be used by service personnel. Use the scanner calibration routine to adjust the scanner settings if necessary. See Calibrating the scanner. SERIAL NUMBER Select this item to update the serial number if you replace the formatter. SERVICE ID Service ID.
Service ID This information appears on the configuration page, which eliminates the need for customers to keep paper receipts for proof of the warranty. Because the MFP does not have an internal clock, the availability of the service ID date depends on the MFP being connected to a source that can provide the date, in this case a time server that is on the same network as the MFP. When the MFP is not connected to a date source, the service ID is not available, and 00000 appears on the configuration page.
Troubleshooting the embedded HP Jetdirect print server If network-connection errors occur, you can disable the HP Jetdirect print server in order to determine if the problem is with the print server or with the network. This procedure requires that you temporarily install an optional EIO HP Jetdirect print server card while disabling the embedded HP Jetdirect print server. To disable the embedded HP Jetdirect print server 1 Turn the MFP off and then on.
