Regulatory information
For regulatory information and requirements, FCC regulations, and the declaration of conformity,
please see the HP Multifunction Finisher use guide.
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.
Parts and supplies
Information about ordering
“Consumables and documentation” in chapter 5 contains FRU and replacement part numbers, and
contains information about products specifically designed for this multifunction finisher. Replacement
parts can be ordered from the HP Customer Support (HPCS) organization.

Power-on sequence
The multifunction finisher performs an initialization procedure when it receives the Recovery Initialize
signal. 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.

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.

Stapling
The multifunction finisher staples the specified number of sheets of paper, and the staple position
depends on the staple mode and paper size.

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.

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.

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.

Troubleshooting process
The troubleshooting process is a systematic approach that addresses the primary problems first, and
then 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).

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.

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

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.

Jam troubleshooting
Jams occur when media either does not reach or does not clear a sensor along the paper path in a
specific amount of time. 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.

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
