Service approach Repair of the multifunction finisher normally begins with a three-step process: 1 Isolate the problem to the major system (the host computer, the network and/or server, or the multifunction finisher system). 2 Determine whether the problem is located in the multifunction finisher, the print unit, or the copy/ scan unit. 3 Troubleshoot the problem using “Basic troubleshooting process flowchart” in chapter 4. Repair is usually accomplished by assembly-level replacement of field replaceable units (FRUs). Some mechanical assemblies can be repaired at the subassembly level. Hewlett-Packard does not support replacement of components on the printed circuit assemblies.

This signal is transmitted from the printer on occasions at power on. The power-on sequence consists of the following actions: Figure 6. Power-on sequence 1 Moves slide: The booklet bin slide motor (M10) drives the slide to move from the standby position. The slide returns to the standby position when the home position is detected. 2 Folding action: The staple-fold motor (M7) drives one cycle of folding action. 3 Moves swing guide vertically: The paddle motor (M2) drives the swing guide to move vertically. 4 Rotates paddler: The paddle motor (M2) drives the paddle to complete one cycle of rotation. 5 Moves stapler: The slide motor (M8) drives the stapler to move from the standby position. The stapler returns to the standby position when detecting the home position. 6 Performs alignment: The front aligning plate motor (M4) and the back aligning plate motor (M5) drive the front and back aligning plates to perform one cycle of alignment. 7 Moves stack-feed roller vertically: The transfer motor (M1) reverses to cause the upper stackfeed roller to move vertically. 8 Moves delivery tray vertically: The shift motor (M6) drives the stacker bin (bin 1) to move from the home position. The stacker bin returns to the home position when it is detected by the full loading sensor (P124). 9 Rotates stacker bin: The delivery motor (M3) drives the delivery belt to complete one cycle of rotation after the stacker bin has descended approximately 25 mm (1 inch). The stacker bin then returns to the home position. 24 Chapter 2 Theory of operation C8088-90902 Basic operation The multifunction finisher ejects paper from the printer either face down or face up. Operations such as job offset are performed when paper is ejected face down. The booklet unit inside the multifunction finisher folds the paper stack before ejecting it. The sequence of operations is controlled by the finisher controller PCB. Video controller PCB DC controller PCB Multifunction finisher Finisher controller PCB Figure 7. C8088-90902 Basic operation Basic operation 25 Simple stacking Flipping action (face-down delivery): l Figure 8. After the paper is reversed, the paper is pulled into the processing tray and ejected face down to the delivery tray. Simple stacking (face-down delivery) Face-up delivery: l Figure 9. The paper is pulled into the processing tray and ejected face up to the delivery tray. Simple stacking (face-up delivery) 26 Chapter 2 Theory of operation C8088-90902 Job offset Job offset is accomplished by pulling sets of sheets forward or backward for sorting. Two aligning plates are used to alternate between the forward and backward directions. Sheets are fed between the delivery rollers onto the processing tray, where a paddle feeds them toward the stopper. The swing guide is in the “up” position during alignment or when a sheet is pulled onto the processing tray. The swing guide is in the “down” position during stack feeding, stack delivery, or stapling. At power on, the finisher controller PCB drives the aligning plate (front) motor and the aligning plate (back) motor to return the two aligning plates to the home position. Note The offset specification is 20 mm, or 0.79 inch (10 mm, or 0.39 inch per side).

C8088-90902 Basic operation 27 Stapling The multifunction finisher staples the specified number of sheets of paper, and the staple position depends on the staple mode and paper size. Paper width Paper width X 1/2 Side stitching (two staples) Landscape image (front) of the device Paper width Paper width X 1/2 Portrait image stapling (back) Figure 11. Saddle stitching (two staples booklet) Staple positions When the multifunction finisher is turned on, the finisher controller PCB drives the slide motor to return the stapling unit to the home position. The stapling unit moves toward the front of the stapler frame, and stops at the slide home-position sensor on the slide PCB. The slide motor is driven a specified number of pulses, and the stapling unit moves to rear standby position and enters the standby state when it reaches the back of the multifunction finisher.

Stapling unit 28 Chapter 2 Theory of operation C8088-90902 Booklet-making Paper fold rollers and the paper pushing plate fold paper in the multifunction finisher. When the rollers start to rotate, the paper pushing plate pushes the paper stack into the gap between the paper fold rollers. When the paper stack is fed approximately 10 mm (0.4 inch) by the rotation of the paper fold rollers, the paper pushing plate returns to the home position. The paper fold rollers and booklet delivery rollers deliver the paper stack to the booklet tray. Half of each paper fold roller is uncovered (the center and the left and right ends are covered). The upper paper fold roller touches the lower paper fold roller at the center and at both ends to feed a paper stack without causing creases. The covered portion of the upper paper fold roller touches the covered portion of the lower paper fold roller, allowing a paper stack to be folded while being fed.

Booklet making (3 of 3) 30 Chapter 2 Theory of operation C8088-90902 Electric circuitry A 16-bit microprocessor is installed on the finisher controller PCB to control the finisher operation sequence and Jet-Link communication with the video controller PCB. The finisher controller PCB drives solenoids and motors in response to the commands received from the video controller PCB through the Jet-Link communication line. The finisher controller PCB also reports information about sensors and switches to the video controller PCB through the Jet-Link communication line. The following are important functions of the IC chips installed on the finisher controller PCB: Figure 16. C8088-90902 l IC21 (CPU) : controls the operation sequence l IC25 (EEP-ROM): backs up the adjustment values l IC23 (flash memory): stores sequence programs l IC1/IC4 (communication IC): communicates with the printer Signal flow between the multifunction finisher and the video controller Electric circuitry 31 Power supply The multifunction finisher power supply adopts a remote switching system. At power on, the printer issues a command to the video controller PCB. The video controller PCB then sends a power-on signal (PWRON-IN signal) to the power supply. When the PWRON-IN signal is at the “H” (high level), the power supply circuit supplies +24 V power and +5 V power to the finisher controller PCB. The +24 V power drives the feed motor, delivery motor, and solenoid. The +5 V power drives sensors, IC chips, and the finisher controller PCB. Figure 17.

other problems, to discover the causes for multifunction finisher malfunctions and errors. Basic troubleshooting process flowchart (page 82) illustrates the primary steps for troubleshooting. An answer to a troubleshooting question allows troubleshooting to proceed to the next primary step. If an answer indicates that additional testing and correction is needed, proceed to the appropriate section in this chapter and follow the directions there. After completing the additional testing and correcting the problem, proceed to the next primary step. Note Always follow this process in sequence. Failure to do so can result in increased repair time, difficulty, and expense. This list describes the basic questions to answer and provides the corresponding troubleshooting sections that define the problem(s). Table 14. Primary steps for troubleshooting Troubleshooting with control panel messages (page 88) Does the printer perform the initialization and power-on sequence? This section contains the procedures for correcting power supply problems. Paper-path test (page 101) Is it possible to perform a paper-path test? This section contains information about troubleshooting paper path and print media problems. Information pages (page 106) Is the media in use acceptable for this multifunction finisher? This section contains information about how to identify print media problems and correct them. 80 Chapter 4 Troubleshooting C8088-90902 Preliminary operating checks Make sure that the conditions in the following lists are met before troubleshooting a specific multifunction finisher problem. Installation environment l The multifunction finisher is plugged in, and specified power is delivered. l Supported print media is being used. l The multifunction finisher is positioned on a solid, level surface. l The line voltage does not vary more than 10 percent from the nominal rated value specified on the power-rating label. l The operating environment for the multifunction finisher is within the temperature and humidity specifications. See “Specifications” in chapter 1. l The multifunction finisher is not exposed to direct sunlight (sudden changes in the multifunction finisher environment can cause media handling problems). Document checks l The selected tray contains media that has been loaded and adjusted correctly. l The selected tray contains the correct amount of media. l The recommended paper is used. l The document is not damp. l The document is not dirty. l The number of sheets being stapled or folded are within specifications. Unit checks C8088-90902 l The paper guide wire is connected. l The attachment rod assembly is connected. l The Jet-Link connector is connected. l The green solid light is the visible LED. l The gap between the printer and the multifunction finisher is level.

See page 50. 2 Lift the interlock switch flag (callout 1) to activate the interlock switch. 1 Figure 76. C8088-90902 Service mode configuration Using the diagnostics tool 85 Switch locations 1 Set the DIP switches (callout 1): • DIP switch 1: set to 0 for self-running mode • DIP switches 2, 3, and 4: set for paper size • DIP switch 5: set for job size • DIP switches 6, 7, and 8: set for the finishing option Note The SW1 (callout 2), SW2 (callout 3), and SW3 (callout 4) switches are located below the DIP switches. 1 2 Figure 77. 3 4 Switch locations 86 Chapter 4 Troubleshooting C8088-90902 Power supply switch To turn on the power supply switch, pull the power supply switch (callout 1) toward you. Note You must turn on the power supply for each testing configuration, and the power supply switch must be off when testing is complete. 1 Figure 78. Power supply switch Paper delivery Face-down delivery 1 To perform face-down delivery (flipping paper), turn on the power supply while pressing SW1 for about three seconds. Face-up delivery C8088-90902 1 To perform face-up delivery (straight paper path), turn on the power supply while pressing SW1 and SW2 simultaneously for about three seconds. 2 Press SW1 again to start the multifunction finisher. 3 Feed paper manually or send a job from the printer to perform the selected option. 4 Set all of the DIP switches to OFF when the job is finished. Using the diagnostics tool 87 Troubleshooting with control panel messages Event log Use the event log to diagnose and troubleshoot multifunction finisher errors and intermittent failures. You can either print or display the event log from the control panel. (Select PRINT EVENT LOG or SHOW EVENT LOG.) The event log is a last in-first out (LIFO), ordered listing of the last 50 entries. The printed event log contains four columns that show event number, page count, error code, and description. The description gives detail to the error messages. The information is useful for troubleshooting. The event log should contain details about the following: l critical errors l jams l sensors sensing out-of-range l deleted jobs l unexpected paper size errors l complex page errors l buffer overflow errors l NVRAM changes l diagnostics tests Interpreting the event log Each individual entry in the log is called an “error,” while all errors that occur at the same page count are called an "event." For details about each error that comprises an event and to better understand the event, see “Multifunction finisher message tables” on page 93. Events usually conclude with a time-out or with no response from the device (error 66.xy in the event log). Turn the multifunction finisher off, and then turn the multifunction finisher on. Use the event log tables in this section to associate errors on the event log with control panel error messages. Follow the recommended action listed in the event log table starting on page 93 for each error or event. 1 Check the event log for specific error trends in the last 10,000 printed pages. 2 Ask the customer for any observed error trends. (For example, do jams tend to occur in a specific area of the multifunction finisher?) 3 Record any specific error trends. 4 See “Multifunction finisher message tables” on page 93 and follow the recommended actions. 88 Chapter 4 Troubleshooting C8088-90902 Sample event log Figure 79. C8088-90902 Sample event log Troubleshooting with control panel messages 89 Control panel messages Be sure to read the exact text of the control panel message, including the error message number and the text, in order to locate the error message in the tables. The printer control panel stores enhanced information. Printer messages that appear on the control panel provide six categories of information. Each message category is assigned a priority. If more than one condition occurs at the same time, the highest priority message appears. When it has been cleared, the next priority message appears, and so on. The messages and their priorities are: Note l Status messages—Status messages communicate the current state of the printer to the user. Whenever the device is ready and online, the device status message READY appears unless warning messages are pending. When the device is performing a task, such as a reset or a test, the associated device status message appears. When the task is complete, the message returns to READY, depending on the current state of the printer. l Warning messages—Warning messages are messages that are important enough that the user must acknowledge them, but not serious enough to cause the printer to stop the printing process. They are usually transient in nature but they can affect the output, and so a record of their occurrence is important. Warnings generally alternate with the READY status message and remain on the control panel until the user touches Continue or presses Stop. Warnings appear in most recent order (LIFO) with duplicates removed. l Error messages—Error messages communicate to the user that some action must be performed, such as adding paper or clearing a jam. Some errors are considered autocontinuable, because the printer shows the error message appears on the control panel for 10 seconds, and then the printer clears the message and continues normal operation. Pressing a control panel key during the 10-second period cancels the auto-continue feature and initiates the function of the key that was pressed. Error messages are limited to 19 seven-bit characters (or 9 two-byte characters) per line up, and to two lines. Unlike status and warning messages, error messages stop the printing process. The user has to either fix the problem or give the device a different command. If the user can continue past the error conditions without actually fixing the problem, then the user should be able to perform the task by touching Continue. If only one option is available when the user touches Continue, printing should continue by applying the option shown. If more than one option is available, the options are listed with the most logical option listed first and highlighted. l Critical error messages—Critical error messages communicate printer failures to the user. Generally, turning power off and then on is required in order for the printer to resume normal operation. If the critical error persists, then the printer probably requires maintenance and the user will have to request a service call. Critical errors are not auto-continuable. l Optional paper-handling accessory warning messages—These messages are similar to the warning messages described above, except that they relate to the multifunction finisher. By default, the message is all that appears if the multifunction finisher does not provide any additional help. The prompt at the bottom of the control panel does not appear. l Optional paper-handling accessory error messages—These messages are similar to the error messages described above, except that they relate to the multifunction finisher. By default, the message is all that appears if the multifunction finisher does not provide any additional help. The prompt at the bottom of the control panel does not appear. Print a configuration page to identify the input or output device that is configured. Notice that the error format only identifies the Jet-Link device number and the device type; it does not identify the input or output device. 90 Chapter 4 Troubleshooting C8088-90902 Device error conditions Operating errors include: l stacker bin full l booklet bin full l staples low l stapler out of staples l too many sheets to staple l too many sheets to make a booklet Open door errors include: l device detached from printer l stapler door open or not closed correctly l top cover open or not closed correctly Paper jam errors include: l paper not reaching a sensor within a specific time l paper stopped at sensor Hardware malfunctions are: C8088-90902 l classified by cause and location of failure l the result of a failing sub-assembly Control panel messages 91 Event log messages Note The error formats for event log messages includes 13.xy.zz for jam conditions, and 66.xy.zz for hardware malfunctions. Event log messages include: l 13: Jam condition l 66: Hardware malfunction • x: Indicates how the paper-handling controller identifies the Jet-Link position at boot-up • y: Indicates the device type 0: paper-handling controller 1: input device 2: output device 3: other • zz: Indicates a jam or hardware malfunction that is identified by an internal numerical error code. Note The internal numerical error code matches the service LED pattern. 92 Chapter 4 Troubleshooting C8088-90902 Multifunction finisher message tables Within the groupings listed below, the alphabetic error messages are listed first, followed by the numeric error messages.

If a jam occurs, a JAM IN LEFT ACCESSORY message appears on the printer control panel. Jams Jams can occur when the following conditions exist: l Paper trays are not loaded correctly. l The print media does not meet the specifications listed in the HP LaserJet Printer Family Print Media Guide. l The media is in poor condition. l The multifunction finisher needs to be cleaned. Send a print job from the problem source(s) to the problem destination(s). Try to recreate the jam errors by performing a paper-path test. See page 101. When evaluating print jobs, make sure that all of the appropriate settings are selected. Keep in mind that application settings take priority over driver settings, which take priority over the printer control panel settings. If a single setting is not present in the application, but is set in the driver, that setting overrides the control panel settings. Clearing jams Note Open and close all multifunction finisher covers to clear the jam message. After removing a sheet of paper, you might need to check other areas for the presence of other paper. All portions of a jammed piece of paper must be removed, or you might experience repeated jams. If the jam persists, try the following: l If PostScript is installed, use the JAM RECOVERY=ON menu item under the PostScript Menu. The multifunction finisher will attempt to automatically recover from jams. l Initiate a form feed from the computer or from the printer control panel. A form feed might flush out any paper or envelopes left in the multifunction finisher. l Check to make sure you have located and removed all scraps of paper from inside the multifunction finisher. Clearing repeated jams C8088-90902 1 Do not use previously printed paper or torn, worn, or irregular paper. 2 Check the media specifications. If it is outside of the recommended specifications, problems might occur. See the HP LaserJet Printer Family Print Media Guide. 3 Clean the multifunction finisher. Jam troubleshooting 105 Information pages To print an information page, see the use guide that came with the printer. Sample configuration page Figure 81. Sample configuration page 106 Chapter 4 Troubleshooting C8088-90902 Media troubleshooting Media defects can cause jams and image defects. If the previously described conditions are corrected and do not eliminate the problem, continue to investigate the media as the source of the defect. Problems with print media are sometimes difficult to detect. Follow a standard troubleshooting procedure to help isolate media-related problems. The steps to follow are: 1 See “Determine the problem source: print media or multifunction finisher” on page 107. 2 See “Isolate a paper path” on page 107. 3 See “Isolate a media brand” on page 108. 4 See “Isolate a media type” on page 108. 5 See “Specifications” on page 14. Determine the problem source: print media or multifunction finisher When determining the cause of a multifunction finisher failure, a distinction must be made between problems that relate to the multifunction finisher itself and problems that involve print media. Often, a problem that seems to be related to the multifunction finisher is actually a matter of poor print media selection or handling. To determine whether a problem is caused by the multifunction finisher or by the media, try the following actions to remedy the situation: l Turn media over in the tray to print on the reverse side. l Rotate sheets 180 degrees (end to end) to feed with a different leading edge. If the symptoms cease, or change in some way, assume that the problems are caused by the print media. Isolate a paper path Use the straightest paper path Some problems can be avoided by using the straightest available paper path. Determine whether the problem is caused by the duplexing process Paper that has just passed through the multifunction finisher can show increased media curl. Media curl increases image dropout, and creates pickup and stacking problems. When the second pass is made, print media might not meet the specifications for moisture and curl. Dry paper can hold static charges that affect print quality and stacking of the duplexed page. Media shrinkage resulting from a second pass through the multifunction finisher can cause image misalignment on the duplexed page. Isolate the source of the jam Define the source of the media that jams. Determine where media jams occur Check where media stops when a jam occurs. C8088-90902 Media troubleshooting 107 Determine whether the multifunction finisher is experiencing misfeeds or multifeed jams The following are some possible causes of misfeeds or multifeed jams: l The media might be too smooth. l The media might be too heavy or too light. l The media does not meet the specifications of the multifunction finisher. l The media might be loaded incorrectly. Turn over the sheets in the paper tray to determine if inream curl is causing misfeeds. l The customer might be fanning media before loading it into the tray. l The customer might be adding media in small amounts. Do not add small amounts of media or mix types of media in the tray. l The multifunction finisher or media storage environment might be too humid or too dry. Isolate a media brand If the multifunction finisher jams with only one brand of media: l Try switching media brands. l If the paper ream in use appears to be old, open a fresh ream of the same paper and load it into the printer. If the problem disappears, investigate storage and handling conditions. Isolate a media type When jams and other problems occur frequently, it is often because the customer is using a special paper. Customers must only use print media that conforms to all Hewlett-Packard specifications, and should always test media before purchasing large quantities. Media should be tested before storage to verify quality printing results. Then, if problems arise, storage or handling conditions can be isolated as the most likely cause. Some types of media that might cause problems are: l adhesive labels l envelopes l transparencies l preprinted forms and letterhead l embossed media l perforated paper l chemically treated paper l synthetic paper l coated paper l other special media 108 Chapter 4 Troubleshooting C8088-90902 Calibration and adjustments Table 21.
