Washer On The Drum Assembly’s Lower Right
Mounting Screw May Cause Dog-earing On Prints
Phaser Xerox Office Group Service Bulletin SB 607
2. Retighten the rear screw to 25 in-lbs.
3. Tighten the lower screw (without washer) and torque to 25 inlbs.
4. Tighten the front screw to 25 in-lbs.
When troubleshooting a persistent dog-ear print problem, ensure
the Stripper Carriage Assembly works correctly and the stripper
blade is not damaged. Also ensure an appropriate paper is being
used.
LOWER RIGHT DRUM SCREW USES NO WASHER
A washer added to the lower right screw that holds the Drum
Assembly to the Chassis on the right side prevents the right
Labyrinth Seal from seating in its proper location. This can cause
the Stripper Carriage to also not be properly located. In very rare cases this results in prints on lighter-weight papers having one
corner folded over on the leading edge (dog-ear) as they are
stripped from the Drum. Occasional dog-earing is normal.
WHAT TO DO
When servicing a drum assembly ensure there is no washer on the
lower right drum mounting screw. Update your service manual’s
Drum Disassembly/Assembly Procedure indicating all the drummounting screws use washers except the lower right screw.
No washer
PARTS STRATEGY
Do not replace the Drum Assembly to correct a dog-ear print
problem. Remount the assembly and ensure the screws are
correctly installed and tightened.
TE
s8400-160a
The proper sequence for tightening the right-side drum screws is:
1. Loosen the three drum screws.

Printhead engineering has developed new drift compensation alg orithms
that improve reliability of the Phaser 8400 printer’s printhead. All printers
serial-numbered below RPC044426 need to have their printhead’s firmware
updated via a downloadable snippet file. Printers RPC044426 and above
already have the new algorithm built in.
The snippet file and a readme file are packaged as files 8400_fw_update.exe
(PC) or 8400_fw_update.dmg (Mac). They are available at:
Follow the readme instructions to download the snippet to a printer.
About a year or so after the printer was manufactured, a printhead that is
not updated will exhibit numerous, random missing jets. The missing jets
may clear with a cleaning cycle but other jets drop out. Downloadi ng the
update file to the printer resolves this problem. There is no means to
determine the printhead’s firmware version. Only downloading the snippet
to the printer will tell you if the printhead firmware is up-to-date or not.
Following the download, the printer prints a download status print.
WHAT TO DO
As you service a Phaser 8400 printer,
check its serial number. If it is between
RPC030017 to RPC044425, download the
printhead firmware update snippet to
the printer. For update tracking
purposes, indicate in your Tech Notes
when you have updated a printer. Also
mark the underside of the exit door with
a “PH” to indicate the printer has been updated.

INSUFFICIENT AC POWER CAN CAUSE 37,002 THRU 37,013
PEST FAULT CODES
AC power supplied by power sources such as uninterruptible power
supplies (UPSs) or DC-to-AC inverter systems may not supply correct
voltage to properly power up the printer. Likewise, other devices
sharing the same AC circuit can cause AC voltage sags that cause the
printer to fail its AC heater PEST tests (Print Engine Self Test).
In both cases the printer may produce any of the following disconnected
heater errors:
• Printhead jet-stack 37,002.47 or 37,003.48
• Reservoir heater, 37,004.40 or 37,005.41
• Drum heater error 37,006.42
• Preheater error 37,008.44
• Ink melters errors 37,009.45 thru 37,013.40
SOLUTION
Verify the AC power source when you troubleshoot a printer exhibiting
any of these errors. Try powering up the printer on a different AC circuit
on a different breaker. Turn off other devices, such as laser printers and
coffee makers on the same circuit.

CAUSE
The printer features several heaters controlled by printer electronics and
powered by AC electricity. The printer itself can power up despite
insufficient or irregular AC voltage but it may fail its AC heater tests.
This is due the test not measuring sufficient current flowing through the
heater at the moment the test runs.
Devices sharing the AC circuit shared with the printer, such as a laser
printer pulse-heating its fuser, a coffee maker heating its warming plate
via a thermo-breaker, or a space heater turning on, may be placing heavy
intermittent demand on the AC circuit. This sudden inductive demand
creates momentary AC voltage sag that causes the PEST test to fail.

TECHNIQUES FOR TROUBLESHOOTING THE 50V POWER
SUPPLY FAULT ERROR CODE
37,016.4x - PEST_FAULT_HM_CLUTCH_DISCONNECT
Despite the “clutch disconnect” message, thi s error code indicates that the
50V power supply failed its PEST test. (The 5 0V supply is loaded with the
head maintenance wipe r clutch in order to test; hence the message when
the test fails.) Follow these steps in the order listed to find a short that is
causing the 50v supply to fail:
1. Checking for a short in electronics module. Turn off the printer and
wait 30 seconds for power supply capacitors to
circuits within the electronics module may occur if the
capacitors are not allowed to fully discharge.
NOTE: It is possible that the power supply is not shorted but instead is
out of spec, which lead s to an error conditio n. You can measure the

• Power Control to I/O board (J800 - gray ribbon cable on right side)
• Power Control right (J400 – 16 wire, multi-color)
• Printhead data interface (J130 – gray ribbon cable on top side)
• Wave amp signal (J790) short gray ribbon cable located on left side)
• Power Control left (J390 – 34 wire, multi-color)
• Y-Axis motor (J280)
3.
Turn on power to the printer.
4. If the PE and PS indicators do not flash, the short is in side the
electronics module. Replace the electronics module and retest the
printer. If PE and PS indicators flash, continue with the next step.
5. Checking for short on the I/O board. Turn off the printer and wait 30
seconds for power supply capacitors to discharge.
6. Unplug the front panel connector (J220) on the I/O board. This
removes the front panel from the I/O board.
7. Plug in the Power Control to I/O board connector (J800). This step
adds the I/O board back to the working electronics module - nothing
else is connected.
8. Turn on power to the printer. If the PE and PS indicators do not flash,
the short is on the I/O board or related cabling.
If the 50V PS LED (viewed thru the cooling grill below the power cord
receptacle) illuminates, the short is on one of the external devices you
unplugged earlier. In this case, systematically tur n off the printer,
plug a wiring harness back in, and turn the printer on until the 50V
supply fails.
Typically, the power supply should measure 50v (47 to 52v).

Troubleshooting Dead or Hung Printers SB637 637
Phaser 8400Xerox Office Group Service BulletinSB 637
1. Turn off the printer. Wait for it to completely shut down. Unplug
the printer’s AC power cord.
2. After at least 30 se c onds, reconnect the power c or d and turn on the
printer.
• If the printer powers-up correctly, try printing the
Configuration Page or Startup Page (or any embedded page).
If the embedded pages print normally, the problem has been
solved.
Techniques For Troubleshooting Printers That Are Hung
At Power-Up Or Appear Dead
Dead or hung printers can fail to power-up for a variety of reasons
ranging from improper AC power source to defective components.
The following steps can help resolve dead or hung printers:
1. Verify the printer is in a hung conditi on
2. Eliminate corrupted data in the printer’s mem ory
3. Isolate the printer from the network
4. Isolate the hard drive (if installed )
5. Verify the power source
Verify The Printer Is Hung
The printer can take several minutes to reach its operating temperature.
Cold environments require more time. If the printer appears to be hung
(unable to respond), ope n the front cover.
• If the front panel message changes from “Warming Up ” to “Close
Front Cover to Continue”, the printer is not hung. Instead, it may
be in the process of warming up, canceling a large job, or even
processing a job.
• If the printer does not power-up correctly, go to the next
procedure.
Isolating Network Issues
Corrupted network traffic, print files, or printer drivers ca n cause the
printer to hang. Use the following procedure to isolate the printer from the
network:
1. Disconnect all communication cables from the printer, power
down the printer for 30 seconds, and then turn on t he printer.
• If the printer does power-up, try printing an embedded page
such as the Configuration page or Startup.
• If the embedded pages do not print, there may be
corrupted data in the printer’s RAM. Complete the
procedure “Eliminate Corrupted Data from RAM”.
• If the embedded pages print normally, go to Step 2.
• If the printer does not power-up correctly, proceed to the
“Isolate the Hard Drive” topic.
2. Try printing an embedded page when the printer is connected to
the network.
• If the embedded pages print normally, go to Step 3.
• If the front panel message does not change after opening the front
cover, the printer is hung (unable to respond).
Eliminate Corrupted Data From Memory
If there is corrupted data in the printer’s memory, the printer may be
unable to generate embedded pages. Use the following procedure to
eliminate the corrupted data:
Service Manual UpdateError! Reference source not found.SB 637 Page 1 of 4
• If the printer stops responding while connected to the network,
there may be corrupt network information getting to the
printer.
3. Send a print job to the printer using the network connection. If the
printer stops responding only after sendi ng the print job, the file or
printer driver may be corrupted. Try to isolate the file and/or
reinstall the printer driver. Reviewing the printer's Network Logs
(front panel Troubleshooting menu > Network Log Pa ges) can
offer clues to a network event that might be confusing the printer.
Page 2 of 4
Phaser 8400Xerox Office Group Service BulletinSB 637
Phaser 8400Xerox Office Group Service BulletinSB 637
Isolate the Hard Drive (if installed)
If the printer is a DX model equipped with a hard drive, corrupted files on
the hard drive may prevent the printer from completing its start-up
sequence. Use the following procedure to isolate problems to the hard
drive. Observe ESD precautions:
1. Turn the printer off.
2. At the rear of the printer, open the access panel (held in place with
two thumbscrews). The hard drive mounts to the access panel.
3. Disconnect the wide, gray data cable from the Hard Drive
Assembly.
4. Turn on the printer.
• If the printer powers on normally, the hard drive must be
replaced.
• If the printer fails to power on go on to the next procedure.
Verify the Power Source
Verify the printer is plugged into a stable power so urce that can supply
enough current for the printer’s initial warm-up. Always plug the printer
directly into a known-to-be- good outlet. If other devices are plugged into
the same circuit, there may not be enough power available for the printer.
The printer can tolerate AC power level fluxuations (brown-outs) . But it
cannot tolerate loss of A C cycles (blips, interruptions) or AC fre que nc y
changes. Also, the printer power must be a standard sinewave waveform.
Note: Many DC-to-AC inverter systems, gas-powered AC generators, and
uninterruptible power supply devices do not output proper
sinewave-shaped AC power. This makes them unsuitable as power
sources for the printer. Likewise, many of those devices cannot
output the current necessary to power the printer.
If the printer is unable to power on, use the following procedure to verify
the power source:
1. Disconnect the printer from the suspect outlet.
2. Plug the printer directly into a stable, known- to-be-good wall
outlet. If possible, monitor the line voltage. For testing purposes,
do not use any of the following:
• Circuits that connect to several other devices.
If the power-up problem only occurs when the printer is plugged
into a surge protector, power strip, UPS, or one specific outlet, then
the problem is with that device or outlet.
3. Verify that both ends of the power cord are firmly plugged in.
4. Turn on the printer.
• If the printer powers on normally, the problem has been
solved.
• If the printer does not power on, go to Step 5.
5. Did the printer start power cycling (turning off and on) after a
power surge from an electr ical storm or power outage?
• If yes, turn the printer off and unplug it. After waiting at least
2 hours, plug the printer into a stable, known-to-be-good wall
outlet and turn it on.
• If no, complete the next procedures found in the printer
Service Manual.
6. Check for illuminated LEDs on the printer’s power supply. Refer
to Service Manual topic “Verifying Power Supply Operation” for
locations of the LEDs. Refer to Service Ma nua l topic "Printer Fails
to Power-Up: PS, PE and the 3.3 V Indicator LEDs are Not
Illuminated" for troubleshooting instructions.

JetFix Snippets Available To
Correct Weak And Missing Jets SB640 640
DOWNLOADABLE SNIPPETS EFFECTIVE FOR CLEARING
WEAK OR MISSING PRINTHEAD JETS
A technique, referred to as JetFix, has been developed that is
effective in clearing stubborn weak or missing jets that a printer’s
regular printhead purge cycle cannot clear. The technique consists
of raising the printhead drive voltage to 255, printing several solid
fills of the missing jet color, returning the drive setting to its default
128 setting, and then performing a printhead clean/purge cycle.
The technique is effective about 50% of the time in clearing a
stubborn weak or missing jet.
This technique has been encapsulated into two sets of downloadable
snippet files to simplify performing the technique. One set of files is
for the Phaser 8400. The other set is for the 8200, 860 and 850. (The
technique is not very effective in the Phaser 840 because of the age
of the printheads).
Each set consists of four snippets; one for each ink color. When a
printer receives a JetFix snippet it will print five double-coverage
solid fills and then perform a printhead clean/purge cycle.
Note: It is normal for the solid-fill prints to show many light
stripes; this will clear with the purge cycle.
If process should be interrupted by a power glitch or a hang, powerdown the printer, wait 30 seconds, and turn on the printer. The 255
Head Adjust setting automatically will be overwritten by the 128
value retrieved from the printer’s NVRAM on power-up.
Phaser 850, 860, 8200, 8400 XeroxOffice Group Service Bulletin SB 640
WHAT TO DO
Before replacing a printhead for a weak or missing jet issue (not
caused by non-Xerox ink) upload the appropriate JetFix snippet to
the printer. Use the snippet that corresponds to the jet’s missing
color. JetFix is effective in clearing printheads with one or two
missing jets that cannot be cleared using the printer’s “Eliminate
Light Stripes” cleaning cycles.
Obtain the snippets from the Customer Support Resources website:

PIVOT PLATES CRACKING RESULTS IN INSUFFICIENT
DRUM OILING
Cracking of the drum maintenance pivot plate results in the pivot
plate not pushing the drum maintenance unit forward enough to
provide sufficient oiling of the imaging drum during a print cycle.
The result is poor ink transfixing and poor print quality.
The pivot plate may crack at either the left end or the right end or
both. This results in a print quality defect, such as dropout or smear,
at the corresponding left or right sides of the prints.

Wiper Belts. Printers manufactured since September 12 are also
being built with wide-style wiper drive belts. The narrow wiper
drive belts shipped on the earlier printers are prone to a
phenomenon called “wiper chatter.” Wiper chatter can lead to jet
color mixing following a printhead cleaning cycle. The color
mixing usually clears after a few prints. Using wide belts requires
that firmware code Ver 4.302 be installed on the printer.

Blurry Prints Caused by Oil-Contaminated Drum
Encoder
OIL ON THE ENCODER WHEEL CAUSES DRUM
ROTATION POSITION PROBLEMS
Oil on the drum encoder’s disk produces erroneous positioning
signals to the electronics
module. This results in the
drum rotating at the wrong
speed during imaging. The
resulting prints appear
blurry, with the image
distorted in the Y-axis,
vertical direction. Figure 1
illustrates the problem.
Horizontal, X-axis printhead
movement is not affected.
Figure 1
The problem is caused by oil
migrating from the drum
assembly’s bearing and
contaminating the encoder
disk as shown in Figure 2.
By design the encoder disk
is immune to some
contamination, but too much
contamination overwhelms
the system.

Jam Open Front Cover (C3T) after Replacing or
Reinstalling the Process Drive Assembly
PROCESS DRIVE ASSEMBLY ALIGNMENT PROBLEM
After replacing the process drive assembly, pivot plate or the drum
maintenance camshaft (or any other procedure requiring the removal
of the process drive assembly), the printer may experience jams from
Tray 2. The jam occurs with paper in the preheater and C3T jam errors
(strip flag timeout during transfix) recorded in the Jam History. In
many cases, Tray 1 (MPT) prints with no jams.
These symptoms indicate that the transfix load module is incorrectly
timed and is therefore not advancing the paper to the strip flag within
the correct timeframe. Therefore the printer reports a front cover jam
and records the C3T jam error.
WHAT TO DO
The majority of the time, the problem is that the drum maintenance
camshaft is out of position by one or two teeth. Correct by:
1. Rotate the drum
maintenance camshaft
clockwise to tilt the
printhead forward to its
home position. (This
disengages the
printhead and its tilt
gear from the camshaft.)
2. Pin the process drive
assembly to keep its two
missing tooth gears in their disengaged positions.

Printer Produces Gradually Lighter Prints
INFORMATION: PRINTERS BELOW SERIAL-NUMBER
WYP142312 AND WYN142344 BENEFIT FROM PRINTHEAD
FIRMWARE UPDATE
Printhead engineering has developed new drift compensation algorithms
that maintain the print quality/density of the Phaser 85xx printer’s printhead.
All printers serial-numbered below WYN142344 (Phaser 8550) and
WYP142312 (Phaser 8500) benefit from having their printhead’s firmware
constants updated via a downloadable snippet file. Printers above the serial
number break already have the new algorithm built in.
The snippet file and a readme file are contained in file 8500-8550_phfw-update.zip. The file is available at:
Follow the readme instructions to upload the snippet to a printer.
As the printhead ages over the years, the prints it produces will gradually
become lighter and lighter. There is no means to determine the printhead’s
firmware constants settings. Only downloading the snippet to the printer will
tell you if the printhead is up-to-date or not. Following the download, the
printer prints a download status print.
WHAT TO DO
As you service a Phaser 8500 or 8550 printer, check its serial number. If it
is below WYP142312 or WYN142344, download the printhead u pdate
snippet to the printer. For update tracking purposes, indicate in your call

Back Channel Trace and Diagnostics using a
USB-to-Serial Adapter
USING A USB-TO-SERIAL PORT ADAPTER TO OBTAIN A
BACK CHANNEL TRACE OR TO RUN PHASER 850
DIAGNOSTICS
Many newer Laptops or PC’s do not have serial ports available. An
alternate method of communicating with the printers is available by
using a USB-to-Serial Port Adapter and its software to communicate
in a serial manner.
WHAT TO DO
Obtain a USB-to-Serial Port Adapter and software for your Laptop
or PC and Load the software as per the instructions provided.
An example of how to load and operate the Port Adapter is
provided below.
Obtaining a VX Works Trace using a USB Adapter – This method
was tested with a Phaser 850. You can also use the adaptor for
running external Diagnostics after modifying the Diags.INI file.
NOTE The instructions contained in this service bulletin were
developed using a Belkin USB/Serial Adapter, P/N F5U109
and the Windows XP O/S. Other USB-to-Serial adapters are
available; however software installation procedures may vary
by brand.
NOTE Xerox is not responsible for any changes made to your laptop
or PC setup to make the adapter software function properly.

1. Load the software from the CD and reboot the PC. Follow
the instructions included with your adapter to install the
necessary software.
2. Connect the USB/Serial adapter to an available USB port on
your PC. Attach the port adapter to the 9 pin Serial cable
(012-1535-00) and the diagnostic pig tail (012-1543-00), and
plug it into the service port on the back of the printer
3. Configure the USB port for diagnostics. For Windows XP, go
to [My Computer] - [Control Panel] - [System], select the
[Hardware] tab, and then select [Device Manager]. Click on
the “+” next to [Ports (COM & LPT)], then right click on the
USB-to-Serial Port device and select [Properties]. Make a
note of the port number (usually COM3 or COM4)
NOTE Check the USB/Serial adapter instructions for
acceptable COM ports. Some adapters may require
that the adapter use COM3 or COM4.
4. Click on the [Port Settings] tab. Set “Bits per second” to 19200,
and set “Flow control” to Hardware, then click [OK].
5. Set up a Hyper Terminal port on the PC. Click [Start] -
6. Name the new connection with the model number of the
printer. Configure the new connection using the COM port
configured in step 3, then click [OK]. Set “Bits per second” to
19200, and set “Flow control” to Hardware, then click [OK].
7. From the Hyper Terminal tool bar, click on [Transfer] and
select [Capture Text]. Click on [Browse], and in the browse
window, navigate to the desktop (or another file where you
wish to save your diagnostic results). Enter a file name for
your trace and click [Save].
8. For the Phaser 850, 860, and 8200 put rear panel DIP-switch 3
in the down position and turn on the printer. For the Phaser
8400/8500/8550 & C2424, no switch is needed. Follow the
Solid Ink PrintersXerox Office Group Service BulletinSB 723
instructions in the service manual for performing a
backchannel trace.
9. The backchannel trace should be displayed in the Hyper
Terminal window. When you have captured the necessary
trace data, click [Transfer] – [Capture Text] – [Stop] to end
data capture. This data will be saved as a text file to the
location specified in step #7, and may now be faxed or emailed to EHS for help with troubleshooting problems on
power up or other out of the ordinary problems where
normal diagnostics may not run.
PHASER 850 DIAGNOSTICS
To run diagnostics using a USB-to-serial adapter you must edit the
DIAGS.INI file to launch the correct baud rate and COM port. Edit
the file with a program such as WordPad. You will also need to
verify that your USB/Serial adapter software supports the COM
port you want to use. Some manufacturers may require that the
adapter is used on COM1 through COM4.
It is recommended that the NO-Floppy diagnostics from the
Partners Web site be used for easy diagnostic operation. Always
place switch 1 only in the down position on the Phaser 850 printer to
run diagnostics.
The following are the settings that need to be changed in the
DIAGS.INI file. Set the Port for the Com port you wish to use. The
baud rate is normally set at 19200. Save the file and launch
diagnostics.
PORT0 = COM1 baud: 0 = 9600
PORT1 = COM2 baud: 1 = 19200
PORT2 = COM3 baud: 2 = 38400
PORT3 = COM4
NOTEBeginning with the Phaser 860, all printers have
built-in diagnostics capabilities and do not require the
use of external diagnostics.

9,035.43 THRU 9,038.46 INK STICK COUNT FAULTS AND
FALSE INK OUT MESSAGES. SOME INK STICKS MAY NOT
RELIABLY ACTUATE INK OUT SENSORS
Features on the bottom of genuine Xerox Phaser 8500/8550 brand ink
sticks actuate the Ink Out Sensor located at the forward end of each ink
stick channel of the printer’s ink loader. The printer reads each sensor
to determine if an ink stick is present and also to count each stick as it
passes by the sensor.
Some ink sticks may not reliably depress an Ink Out Sensor’s flag. This
can lead to false Ink Out messages as well as Ink Stick Count faults.
Using Phaser 8400 ink sticks in a Phaser 8500 or 8550 will also cause
9,03x.4x ink stick count faults. The Phaser 8400 ink sticks do not have
the features required to actuate the ink out flags.
WHAT TO DO
When you service a Phaser 8500 or 8550 printer for:
• a persistent Ink Out message
• 9,035.43 Cyan Ink Stick Count Fault
• 9,036.44 Magenta Ink Stick Count Fault
• 9,037.45 Yellow Ink Stick Count Fault
• 9,038.46 Black Ink Stick Count Fault
Test the Ink Out Sensors for proper operation.
Inspect the Ink Sticks.
TESTING THE INK OUT SENSORS
Use this procedure to test if an Ink Out Sensor’s flag works correctly.
1. Remove ink sticks from the ink loader’s channels.
2. Place the printer in Diagnostics Mode by:
Service method
a. Turning on the printer and as
XEROX appears on the
screen, press and hold the
Back and Help button until
Beginning Service Mode
Initialization appears.
b. Scroll to and execute test
Monitor: Sensors
3. Insert the clean eraser end of a pencil thru the lowermost oval slot.
(The eraser end of a pencil closely simulates the bottom rail shape of
a Xerox ink stick.)
4. Slide the pencil down the white channel guide until the sensor is
tripped. A sensor change is displayed on the control panel. When
the flag is depressed, the front panel will read <color> Ink Present H. When released, the reading will change to L. The test will only
display a reading when a sensor change occurs. If a flag is stuck, no
sensor reading will be displayed on the front panel.
5. If the sensors are not working properly, follow standard service
procedures and replace the ink loader assembly.
6. If the ink out sensors work correctly, identify the ink stick(s)
being used in the printer.
IDENTIFYING INK STICKS
If Genuine Xerox Phaser 8500/8550 Ink Sticks are being used, check
for defects in the ink sticks and replace. If no defects are found,
replace the ink loader assembly.
• If Phaser 8400 Ink Sticks are being used, they will not properly
actuate the ink loader sensors. Do not use Phaser 8400 ink sticks
in a Phaser 8500 or 8550 printer.

SUBJECT: Criteria to Determine if Printhead Failure
Caused by the Printer Being Tipped While Hot
OPERATIONAL GROUPS: ALL
PROBLEM
Several problems can be associated with a Printhead that tipped
while hot including Massive Jet Loss, Ink Reservoir Overflow, and
Ink in the Air Purge Hose.
CAUSE
Tipping the printer while the Printhead is still hot. The printer
should be powered off and allowed to cool for 30 minutes before
moving.
SOLUTION
Overview
The solid-ink printer, while in its powered-on state, contains
liquefied ink. Only when the printer has been turned off and
allowed to cool for 20-to-30 minute does this ink solidify. Once the
ink has solidified can the printer be safely moved or shipped.
While its ink is in a liquid state, tipping or tilting the printer allows
ink to infiltrate upper portions of the printhead. This ink infiltration
causes serious, multiple jet loss and well as ink overflows. The ink
blocks the flow of pressurized air thru the purge hose into the
printhead during a cleaning cycle; purges become ineffective.
Similarly, air in the reservoirs is block by the ink so it cannot vent
out as ink is melted into the reservoir. Since the ink cannot
displace the trapped air, it backs up the ink reservoir funnel and
overflows.
Tipping the printer allows ink in the reservoir chambers ...
to flow thru the hole surounding the ink level sense probe ...
into the upper air chamber ...
where it can block the ink hose port.

Ink Reservoir Overflow
Following an ink melt cycle, look for:
• An abnormally raised level of ink in a reservoir (shown in
the Magenta reservoir). Ordinarily the ink level is
maintained even with the filters in the reservoir (as shown
in the Black reservoir). Ink should not rise above the
filters.
• If the ink level rises high enough it overflows and leaks
between the metal reservoir funnel and the plastic
insulating panels. (See Figure 4).
Ink in Air Purge Hose
Look for:
Ink in the purge hose where it connects to the printhead. This is a
sure sign the printer was tipped while hot. Ordinarily the hose
appearance is uniformly translucent. See Figure 3.

Look for:
• Ink accumulations under the printhead or on the
printhead’s circuit board. Successive ink melt cycles and
overflows cause ink to accumulate under the printhead.
SERVICE BULLETIN
Massive jet loss
Look for:
• Many missing jets in the same color. May be in multiple
colors. See Figure 6.
• If there are ink accumulations under the printhead (Ink
Reservoir Overflow), then the printer was probably tipped
while it was in a typical user setting.
• Ink accumulations often lead to printhead movement faults
such as 7,010.43. (See Figure 5)
Figure 5.
The ink melted to fill the reservoir cannot immediately displace the
air trapped in the reservoir. Instead the ink backs up in the ink
reservoir funnel and overflows. Since the ink overflows between
the metal reservoir and the printhead’s plastic panels it is not
immediately apparent that the overflows are taking place. Only
after numerous ink melt cycles, which may be hours or days later
after the printer was tipped, does the problem reveal itself.
Multiple missing jets may occur during high-coverage printing due
to ink starvation. Since the ink is not refilling the reservoir, the
printer prints to the point that there is not enough ink to supply the
jets and they run dry. This failure will look similar to the illustration
in the next topic, Massive Jet Loss.
• If the lost jets occur when the printer is powered up, but
there are no indications of Ink Reservoir Overflow as
described earlier, then the printer was probably tilted (while
still hot) after it was shut down.
Air bubbles form in the ink when the ink cools and solidifies
following the shutdown. A power-up cleaning cycle flushes the airbubble laden ink out of the printhead. If the purge hose is block by
ink and cannot properly pressurize the printhead, then the purge
cannot flush out the air bubbles that formed in the ink when the ink
solidified. The jet loss is due to air bubbles in the printhead due to
an ineffective purge cycle.

Product: Phaser 8560
Operational Groups: DMO
PART NUMBERS FOR DEVELOPING MARKETS
ORGANIZATION’S PHASER 8560W PRINTER
A version of the Phaser 8560 with a different set of ink shapes is being
introduced in the DMO. It is labeled Phaser 8560W. The table below
lists the parts relevant to servicing this printer.
The yield on these ink shapes is approximately 1300 pages per stick.
Record these part numbers in your service manual. These updates will
be reflected in the next electronic update to the service manual.
Customers observe excessive ink consumption due to printhead
cleaning cycles.
CAUSE:
This behavior is most likely caused by Energy Star mode being enabled
and active. Energy Star mode forces machines to lower their printhead
temperatures below the freeze-off temperature level. Upon wake-up, the
machine will consume significant amount of ink while performing a
purge cycle.
Note:
Energy Star mode is only activated at the factory when the specific
model is ordered.
SOLUTION:
When troubleshooting a machine exhibiting the above behavior; use the
following steps:
1. Validate that the machine is an Energy Star model by the following
methods:
8560
During power-on the machine will display the Energy Star logo on
the control panel. It follows the XEROX splash screen.
8560MFP
Note the Energy Star label applied to the front of the machine.
2. Print a Service Usage Profile and inspect the Print Head Clean
Source (Token 282). Evaluate the CAP category, as it will be
incremented every time the machine initiates an EnergyStar purge.
3. After validating the issue is related to the Energy Star behavior;
follow these steps:
a. Explain to the customer that ink is being consumed because
their machine is cleaning the printhead before printing. Autopurging only occurs if the machine is turned off and on, or has
remained idle long enough to go into Energy Star mode.
b. Explain to the customer that we can fix the problem by disabling
Energy Star, but their machine will no longer comply with the
newest EnergyStar standard (TEC). The machine will still meet
the previous EnergyStar standard.
c. Disable Energy Star; ONLY
at the customer’s request.
Disabling EnergyStar mode
8560:
a. Select the Printer Setup menu via the control panel
b. Select the Printer Controls menu
c. Select Power Saver: On
d. Change Power Saver to OFF
Note:
The Power Saver menu item is only available on printers that
have had Energy Star mode activated by the factory.
8560MFP:
a. Locate the “8560MFP_ESTAR_OFF.ps” file on the Xerox
Driver/Utilities website and download to a local computer.
b. Open the “Readme.txt” file for download instructions.
c. Download the “8560MFP_ESTAR_OFF.ps” file.
d.
e. To verify that Energy Star has been disabled; monitor the
machine for 5 minutes. The machine should stay in READY
mode during this timeframe. If the machine enters STANDBY
mode, this means that EnergyStar is still active. The previous
step must be repeated until EnergyStar is disabled.
ERRATIC BEHAVIOR IN PRINTERS AND MFPS CONFIGURED
WITH 768 MBYTES OF RAM
Printers configured with 768 Mbytes of RAM (one 512 MB and one 256
MB RAM DIMM) may experience erratic behavior such as hanging on
power up, hanging or restarting during printing, or restarting when
coming out of Power Saver mode.
CAUSE
The presence of a 512 MB DIMM in Slot 1 (top slot) together with a 256
MB DIMM in Slot 2 (bottom slot) triggers the erratic behavior.
Dual-rank 512 RAM DIMMs (noted by the code HDY in the part
number printed on the DIMM) in the top slot exhibit the most erratic
behavior. Single-rank 512 RAM DIMMs (noted by the code HY in the
part number printed on the DIMM) in the top slot perform better but
are still prone to hangs and restarts.
RAM HANDLING TIPS
• Use static electricity safeguards when handling RAM. Ground
yourself to the printer frame before touching RAM DIMMs.
• Use proper techniques to remove RAM DIMMs from their
connector.
• Use a single fingertip to release the plastic connector latch at
each end of the RAM DIMM.
• Gently press slightly outward on the latch to release it.
• Release the latches one end at a time. The RAM DIMM will
pop forward when released.
SOLUTION
Ensure that the 512 MB RAM DIMM is installed in Slot 2 (bottom slot).
In testing no erratic behavior has been noted when the 512 MB RAM
DIMM is installed in Slot 2.
The erratic behavior has only been noted in printers with a 512 and a
256 RAM DIMM installed. Other DIMM combinations such as 512
alone, 512/512, 256 alone, and 256/256 performed as expected.
When you encounter a squeaking bushing, replace both bushings.
The replacement bushings must securely engage the ground plane to
avoid static build-up.
PROBLEM: SQUEAKING DURING PRINTING DUE TO DRY
BUSHINGS
A small number of printers may start to produce a squeaking noise
during printing due to defective bushings installed in the printer's rightside frame. The bushings will likely fail (squeak) early in the printer's
life. Most likely within less than 1,000 prints. The problematic bushings
are only installed in the right-side frame and support the take-away
roller shaft and the duplex-roller shaft.

604K54910
The 7,010.43 error code indicates the printer is having difficulty tilting
the printhead forward from the parked position to the print position.
There are several printer systems involved in tilting the printhead so
troubleshooting the error can be challenging. The printer does not
directly sense the printhead's tilting position. Instead it applies drive
current to the process drive motor, and monitors the motion of the
motor's rotation encoder for "following error". For a particular drive
voltage the encoder should rotate at a particular rate as the printhead
(driven thru the process drive, the DM camshaft, and the head tilt gear
train) tilts forward. If the printer does not see the expected encoder
readings it assumes a tilt failure.
These instructions are also useful for troubleshooting the less common
7,007.49, 7,008,41, and 7,009.42 error codes.
• When you encounter a 7,010.43 error, determine when the
7,010.43 fault occurs.
• Does it occur during boot-up the first time the printer
attempts to tilt the printhead forward? If so, go to topic
"Fails on First Tilt".
• Does it occur later in the boot process after successfully
tilting a few times but failing when it begins to start a
cleaning cycle? If so go to "Fails on Subsequent Tilt".
FAILS ON FIRST TILT
When the printhead fails to tilt forward on the first tilt, it is often due to
something physically interfering with the printhead movement:
1. On rare occasions, you may find the printhead appears to be
stuck to the wiper blade. This can occur if the printer was
improperly shut down while performing a printhead cleaning
cycle.
2. In this case:
a. Allow the printhead to heat up to soften the ink.
b. Gently separate the printhead from the wiper.
c. Manually lower the wiper (by rotating the wiper drive
gear) and set the printhead into the print position next
to the drum.
3. Is the printhead being centered by the X-axis motor? Does it
stay centered? Watch the left-right motion of the printhead.
Also watch for smooth left-right movement; if the nose-cone
threads are stripped, the printhead movement may be jerky
and irregular. When the printhead is tilted forward in the print
position, the X-axis nosecone is always in contact with the
printhead's stub shaft. When the printhead is tilted backwards
into its parked position, the X-axis nose cone is retracted away
from the printhead (no contact).
The printhead should travel all the way to the left (home) and
then halfway back to be centered to the drum. Once centered,
the printhead can then tilt forward. If the printhead does not
move left-right:
a. Check for ink in the roll block (from an ink overflow).
If you find ink in the roll block, power the printer up in
Service Diagnostics and run the Exercise Heaters: All
Heaters On test. This will soften the ink and allow you
to remove the ink block (it will be hot!) to clean it.
c. Does the motor rotate? If not either the motor is bad
and must be replaced or the motor drivers in the
electronics module are bad and the electronics module
must be replaced.
d. Does the X-axis motor hold the printhead in the
centered positioned? If it does not, either the motor is
failing or the motor drivers (in the electronics module)
are bad.
4. At the left side of the printer verify that the printhead X-axis
return spring hook is correctly located in the printhead's leftend stub shaft at the center of the roll block (shown in the
photo above). Ensure the spring and spring hook are not
obstructed or interfering with the printer frame.
5. Verify that the process drive assembly is correctly timed as
described in the topic "Homing the Process Drive Train" in the
service manual and Service Bulletin 714.
Check for ink in
the roll block
b. Does the X-axis motor rotate? If the printhead is not
pushed right-left, remove the x-axis motor and restart
the printer.

Ensure none of the process drive mounting posts are broken. If
you encounter a broken post, repair it using the 604K55230
Broken Post Repair Kit. Refer to Service Bulletin 766. In
Europe you can optionally use repair kit 604K54910.
6. Is one of the printhead restraints cracked? It may be necessary
to remove the restraints to verify whether cracks are present.
Check the printhead
restraints for cracks
7. Inspect the gray printhead data cable. Has the data cable choke
coil fallen behind the printhead? The choke coil should be
attached by Velcro. Also verify that the printhead heater
wiring harness, next to the gray ribbon cable, is also properly
dressed and restrained.
8. Is each printhead restraint lock arm lowering when the wiper
assembly is lowered? Verify that the printhead is centered and
not in contact with the lock arms. If the spring-loaded lock
arms do not freely move, replace the printhead restraint.

9. Check for ink spills or shards in the roll block and under the
printhead. At the left side of the printer examine the roll block
and printhead stub shaft for evidence of ink. Remove the
waste tray and examine the area under the printhead for ink
accumulations. Also look for ink shards under the DMU.
Look for shards of
ink in the waste tray
cavity
10. If there is evidence of ink under the printhead, there could be
ink in the printhead tilt gear train. Remove the printhead and
inspect the tilt gear train for shards of ink.

11. Inspect the drum maintenance (DM) cams for cracks. Most
often it is the right cam that cracks. Remove the DMU and lift
the pivot plate out of the way to inspect the right cam. Note: It
is possible to have a cracked cam that still functions normally.
Even so, replace a cracked DM camshaft when you find one.
Check for cracked DM
cams
12. If the DM camshaft was previously removed it is possible that
the left-end bushing fell out of place from the inside of the leftside frame. Verify the bushing is in place. If the bushing falls
out of place, it usually ends up under the Y-axis motor body.
Break in the new roller by doing the following:
a. Turn off the printer
b. Remove the left and right covers.
c. Manually raise the DMU into contact with the drum by
lifting it by its handle. Hold it against the drum.
d. Rotate the drum for about 50 revolutions by turning the
drum pulley on the left end of the drum.
e. Reassemble the printer and test.
2. Inspect the DM cams for cracks. (Illustrated in Step 11 of
previous topic.) Most often it is the right end cam that cracks.
Remove the DMU and lift the pivot plate out of the way to
inspect the cam. Note: It is possible to have a cracked cam that
still functions normally if the cam has not spun out of position
on the shaft. If a cam is cracked, replace the camshaft
assembly.
3. If the drum maintenance camshaft was replaced, it is possible
the right side ground plane was bent or bulged-out. This
ground plane bulge can force the right end bushing and DM
gear against the process drive gear train adding friction load
into the system.
FAILS ON SUBSEQUENT TILT
When the printhead fails on a subsequent tilt, it is usually caused by
something adding more drag or friction into the tilt drive system. The
printhead tilts forward at certain times during power–up but faults while
making the precise positioning needed for a printhead clean cycle.
Was a new Drum Maintenance Unit recently installed? The oil roller of
new DMU may be stiff, especially if cold. During the printhead tilt cycle
the DMU is lifted against the drum. If it is too stiff it may exert extra
drag into the system.

The ground plane should
be flush against the
black side frame
Note for removing a bushing from a ground plane: Use a
rotating, twisting motion on the bushing instead of pulling it.
4. Check the action of the printhead overload spring. When the
p
g
printhead is tilted back it presses down against the overload
spring. As the printhead tilts forward the spring pushes up
against the printhead. If the spring is dragging against another
object such as the X-axis return spring or the printer frame that
can change the load on the tilt system and the printer may
declare a fault. Inspect the overload spring for interference and
a smooth lift action.

Ensure the printhead
overload spring moves
freely and does not

5. A lack of grease on drum maintenance cams-to-pivot plate
contacts points could induce more drag into the system.
Remove the paper preheater to inspect the contact points.
Grease if necessary (use Nye Rheolube 368, part number
070E00890). You will need to remove the Y-axis motor to
access the left end of the pivot plate if greasing the contact
points is needed.
Ensure the points where
the drum maintenance
cams contact the pivot
plate are lubricated
Page 6 of 7
CHECK THE HEAD TILT ENGAGE MECHANISM
1. Verify the head tilt engage mechanism engages and
disengages. When the head tilt has been reset (by manually
rotating the drum maintenance camshaft one revolution) the
two arrows on the left side of the printer frame point at each
other indicating head tilt is disengaged. (This is described in
the Adjustments and Calibrations chapter of the service manual.)
The arrows point to each
other when the tilt
mechanism is disengaged.
Remember: the printhead must be centered to the drum prior to
rotating the drum maintenance cam to reset printhead tilt
engagement. If the printhead is not centered use a small flatblade screwdriver to turn the X-axis motor shaft to center the
printhead.
Head tilt solenoid
2. All printers except the 8400 feature the head tilt solenoid.
Verify that when the head tilt solenoid fires the head tilt
mechanism is engaged. If necessary, use service diagnostics
Exercise Menu: Tilt Solenoid. When tilt is engaged, the
indicator arrows will not then point at each other. For the 8400
slightly raising the printhead wiper will engage the head tilt
mechanism.
3. Verify that the wiper is not misaligned (left end too high
relative the right end) and prematurely engaging head tilt.
Wiper alignment is described in the service manual under the
topic Wiper Alignment.
4. As a very last resort if all other troubleshooting does not resolve
the problem, then perform a PS and PE NVRAM reset. Restart
the printer in service diagnostics mode as described in the
service manual. Navigate to the Function Menu and execute
the Clear PS NVRAM and Clear PE NVRAM functions. This
erases all the printer's stored network and engine settings.
Then run the Set PE NVRAM to Defaults function before
exiting diagnostics mode.
Issue. Under certain circumstances some solid ink printers may
produce a false 7,010.43 head tilt error. The issue involves an
accumulation of multiple part tolerances. This accumulation results in
too much load error on the printer's process drive motor.
Solution. Flash the printer with updated code.
Less than 1% of printers are likely to encounter this tolerance stack-up
condition.
A code update will be effective in cases in which a new factor has been
introduced to the printer such as a recently replaced drum maintenance
unit. Usually the fault occurs when the printer awakens from Power
Saver mode and may be intermittent in nature.
If a printer is emitting 7,010 head tilt error codes for something
physically wrong in the printer the code update will not correct the
fault condition.
WHAT TO DO
Determine if the 7,010 fault code is being caused by something wrong in
the printer. Refer to Service Bulletin 768. Some common causes are:
• Ink in the rollblock from an ink overflow (in such a case the
printhead may need to be replaced)
• Ink shard in the printhead tilt gear
• Cracked/malfunctioning printhead restraints
• Cracked drum maintenance cam
• Stripped gears in the process drive assembly
• Cracked left or right printhead restraint
• Broken process drive mounting posts (repair using 604K55230
Post Repair Kit)
• Failing x-axis motor or motor drivers (x-axis motor can't
maintain printhead's x-axis position)
If there is no apparent reason for the 7,010 fault then flash the printer.
UPGRADING PRINTER FIRMWARE
If the printer is currently in a Ready state:
1. Upload the "Ready state" file appropriate for the model of printer.
Wait for the upload to complete – DO NOT interrupt the upload.
2. The printer will restart. Allow it to boot up to Ready.
The Error state update file will work on printers in their Ready state as
well as printers in an Error state. It just turns off the "Firmware Upgrade
in Progress" caution page prior to flashing the printer.
Keep in mind the update will only fix printers exhibiting false 7,010 head
tilt faults. It will not mask a true head tilt fault caused by an electromechanical malfunction of some kind.
If the printer is currently in an error state. The printer cannot be
directly flashed while it is in a fault state. In that case you must power
the printer up in a Manufacturing mode. To do this:
1. Power-off the printer.
2. Jumper the top two pins
of the Factory Only
connector with a 2 mm,
two-pin jumper
(commonly used on hard
disk drives).
3. Power-up the printer.
The control panel will be
black/white inverted.
Wait for the printer to
display Ready on the
control panel.
4. Upload the "Error state" update file appropriate for the model of
printer. Wait for the upload to complete – DO NOT interrupt the
upload.
5. The printer will restart. Allow it to boot up to Ready.
6. Power-off the printer.
7. Remove the jumper.
8. Power on the printer.
Alternate method to power-up printer to Ready state.
If the printer is producing head tilt faults because it is detecting to much
load you may be able to get the printer to temporarily power up to Ready
by reducing the load on the process drive.
1. Power-off the printer.
2. Remove the Drum Maintenance Unit (DMU).
3. Remove the Drum Maintenance Pivot Plate from the printer.
4. Plug the Pivot Plate back into the I/O board (J860) so the printer
thinks the pivot plate is installed.
5. Insert the DMU into the pivot plate so the printer thinks the
DMU is installed.
6. Power up the printer.
If the printer powers-up to ready you can flash the printer. This is a
good indication that the code upgrade will resolve the 7,010 error issue.

Меры электробезопасности
Источник питания
Для принтеров, рассчитанных на питание от источника 115 В, нельзя
использовать питание с действующим значением более 135 В между
проводами питания или между любым из проводов питания и землей.
Для принтеров, рассчитанных на питание от источника 230 В, нельзя
использовать питание с действующим значением более 254 В между
проводами питания или между любым из проводов
Используйте только рекомендованные кабель и разъем электропитания.
Данное руководство рассчитано на квалифицированного сервисного
инженера.
Подключайте трехпроводный кабель питания (вилка с контактом
заземления) только к заземленной электрической розетке. Если нужно,
обратитесь к квалифицированному электрику для установки
электрической розетки с заземлением. Если аппарат будет отсоединен

Меры безопасности по предотвращению электростатического
разряда
Некоторые полупроводниковые элементы и соответствующие узлы, на
которых находятся эти элементы, чувствительны к электростатическому
разряду. К таким элементам относятся интегральные схемы (ИС),
большие интегральные схемы (БИС), полевые транзисторы и другие
полупроводниковые приборы. Описываемые ниже меры позволят
снизить вероятность повреждения этих элементов статическим
электричеством.
Убедитесь, что на шасси или печатную плату не
также соблюдайте все остальные меры предосторожности.
■Непосредственно перед тем, как дотронуться до узла, содержащего
полупроводниковые элементы, снимите электростатический заряд со
своего тела. Это можно сделать, дотронувшись до заземленной
поверхности или надев на запястье антистатический браслет,
соединенный с заземленной поверхностью. Кроме того, ношение
заземленного браслета позволит избежать накопления на теле
дополнительного статического заряда. Для того чтобы избежать
поражения
электрическим током, обязательно снимите заземленный
браслет перед тем, как подать питание на аппарат.
подается питание, а
■После того, как чувствительный к электростатическому разряду узел
будет вынут из антистатического пакета, кладите его только на
заземленную токопроводящую поверхность. Если антистатический
пакет проводит электрический ток, вы можете соединить его с
заземлением и использовать как токопроводящую поверхность.
■Не используйте распыляемые вещества, содержащие фреон. Они
могут создавать статический заряд, достаточный для повреждения
некоторых устройств.
■Никогда невынимайтесменныйэлементилиэлектрический узел из
защитной упаковки, пока не будете готовы его установить.
■Непосредственно передснятиемзащитногоматериала с выводов
устанавливаемой детали, прикоснитесь этим материалом к шасси
или к цепи, в которую будет установлено устройство.
■При работе с распакованнымиустанавливаемымидеталямисведите
свои движения к минимуму. Движения, которые приводят к трению
деталей одежды друг о друга, или поднимание ног с покрытого
ковром пола могут привести к созданию электростатического заряда,
способного повредить устройство, чувствительное к статическому
электричеству.
■Обращайтесь с интегральными схемами и модулями EPROM
аккуратно, старайтесь не погнуть их выводы.
■При установке или вставке деталей на печатные платы будьте
особенно внимательны при выборе положения установки.

Средний срок службы комплекта обслуживания барабана зависит от
емкости этого комплекта. Например, комплект стандартной емкости
позволяет создать 10000 отпечатков, независимо от используемых
цветов. Комплект обслуживания барабана большой емкости для
моделей 8400 и 8550/8560 позволяет отпечатать 30000 страниц при
степени заполнения до 20% и 20000 страниц, когда степень заполнения
превышает 20%. Модели Phaser 8500 не поддерживают комплект
большой емкости для 8550/8560.

Убедитесь, что принтер установлен на устойчивой невибрирующей
поверхности. Посоветуйте пользователю соблюдать осторожность и
не встряхивать принтер при загрузке материала для печати или при
закрывании передней дверцы. Во время работы чернила
расплавляются и могут вытечь из резервуара печатающей головки, и
привести к появлению дефектов печати.
