2. Diagnostic Information
Use the error indicator table, symptom tables, service checks, and
diagnostic aids to determine the failing part.
Start
Service error indications show as a series of flashes of the Power
light. There is a pause between each series of flashes. If your printer
has an error indication, locate the series of flashes in the “Error
Indicator Table” on page 2-2 and take the indicated action. Unplug
the printer to clear the error indicator.
If an error indicator appears, go to the error indicator table and take
the indicated action for that error.
The printer also logs the last occurring error. If you think it may have
an intermittent error, or the error indicator lights have been cleared,
you can retrieve the error:
1. Run the “Print NVRAM Contents” on page 3-6. The last error
appears at the bottom of the page.
2. Run “Initialize Error Log” on page 3-3 to clear the error (the error
may not be the result of a current error).
3. Run the “Test Page” on page 3-7. If no error appears, go to
“Power-On Self Test (POST) Sequence” on page 2-2.

•Performthe“Test Page” on page 3-7. Look for a
break in the diagonal line of the test pattern. A
broken line indicates one or more print nozzles
are not working. Run the test again to verify the
failure. If there are even breaks in the diagonal
line similar to the pattern shown below, replace
the system board.
If there is a single break or random breaks in the
diagonal line check the following:
• Check the gold-plated contacts, on the end of
the cable that connect to the carrier, for dirt and
wear. Use only a clean dry cloth to clean the
contacts. Also check the cable for damage. You
mayneedtoremovethecablefromthecarrier
to inspect it.
• A worn rubber backer results in poor contact
between the printhead cable and the print
cartridge. Check the rubber backer for wear.
• Refer to the test page. The temperature value in
Celsius, or the message “Thermal Sensor Not
Installed” is printed. If the thermal sensor is not
installed or malfunctioning, and the printer is
operating in a warm environment> 104F (40C),
excessive ink may flow f rom the cartridge. Be
sure the thermal sensor is connected to J7 on
the system board.
If the thermal sensor is connected and a
“Thermal Sensor Not Installed” message prints,
replace the thermal sensor.
Note: Printing slows to prevent overheating and
excessive ink flow, when the temperature is
above the normal operating range, or when
printing complex graphics.
The normal operating temperature range is
60Fto90F(16Cto32C).

Encoder Sensor Test
This test disables the printer motors to let you manually move the
carrier to verify the encoder is working correctly.
To run the test:
1. Turn the printer off and place a two pin jumper on connector J6
as shown below. (Pins 1 & 2).
2. Ensure the manual paper slot is empty.
3. Press and hold the Paper Feed button while turning the printer
on and continue to hold until the Busy Light begins to flash.
• Manually moving the carrier to the left causes the Power
Light to flash.
• Manually moving the carrier to the right, causes the Busy
Light to remain on.
If the test fails power off the printer and remove the carrier
assembly without unplugging the printhead cable.
Power on the printer and check for +5 V dc at pins 1, 2 and 3 of the
encoder card connector. See “Connector Locations on page 5-1.”
1. If voltage is not present, check the printhead cable for opens to
the encoder card. If the printhead cable is good, replace the
system board.
2. If voltage is present, check the sensor on the encoder card by
monitoring pin 3 of the encoder card connector as you pass a
piece of paper through the sensor. The voltage should go from
+5 V dc to 0 V dc. Turn the power off and back on to make this
check again. If the voltage at pin 3 does not change, replace the
encoder card. If the symptom remains, replace the printhead
cable.

4. Repair Information
This chapter explains how to make adjustments to the printer and
how to remove defective parts.
Note: Read the following before handling electronic parts. When
working on the printer, always unplug the printer from the wall outlet.
High voltage is present in the power supply as long as it is plugged
into the wall outlet.
Handling ESD-Sensitive Parts
Many electronic products use parts that are known to be sensitive to
electrostatic discharge (ESD). To prevent damage to ESD-sensitive
parts, follow the instructions below in addition to all the usual precautions, such as turning off power before removing logic boards:
• Keep the ESD-sensitive part in its original shipping container (a special
“ESD bag”) until you are ready to install the part into the printer.
• Make the least-possible movements with your body to prevent an
increase of static electricity from clothing fibers, carpets, and furniture.
• Put the ESD wrist strap on your wrist. Connect the wrist band to the
system ground point. This discharges any static electricity in your body
to the printer.
• Hold the ESD-sensitive part by its edge connector shroud (cover); do
not touch its pins. If you are removing a pluggable module, use the
correct tool.
• Do not place the ESD-sensitive part on the printer cover or on a metal
table; if you need to put down the ESD-sensitive part for any r eason,
first put it into its special bag.
• Printer covers and metal tables are electrical grounds. They increase
the risk of damage because they make a discharge path from your
body through the ESD-sensitive part. (Large metal objects can be
discharge paths without being grounded.)
• Prevent ESD-sensitive parts from being accidentally touched by other
personnel. Install printer covers when you are not working on the
printer, and do not put unprotected ESD-sensitive parts on a table.
• If possible, keep all ESD-sensitive parts in a grounded metal cabinet
(case).
• Be extra careful in working with ESD-sensitiveparts when cold weather
heating is used because low humidity increases static electricity.
