Service Checks
Carrier Transport Service Check
FRU Action
1 System Board Unplug the printer and disconnect the carrier
transport motor connector (J4) from the system
board. Plug in the printer and check for
approximately 12 V dc between (J4-1) and ground.
If the voltage is incorrect, replace the system
board. If the voltage is correct, check for carrier
transport motor pins shorted to the housing. If a
short is detected, replace the carrier transport
motor.
2 Carrier Transport Check the motor for binds, or loose motor pulley.
Motor
A noisy or chattering motor or a motor that fails to
turn can be caused by:
An open or short in the motor.
An open or short in the motor driver on the system
board.
A bind in the carrier transport mechanism.
With the carrier transport motor cable
disconnected from the system board, check for
zero to ten (0 - 10) ohms between the following
pins on the motor:
J4-1 and J4-2
J4-3 and J4-4
If the readings are incorrect, replace the motor.
3 Carrier Guide Rod Clean the carrier rod.
Note: Lubricate the rod and the carrier rod bearing
surfaces with grease P/N 99A0394.
4 Carrier Transport Check for worn, loose or broken parts. Check for
Belt obstructions blocking carrier movement.
Idler Pulley Parts
Carrier Frame Carrier to carrier frame engagement should be
lubricated with grease P/N 99A0394.
Diagnostic Information 2-5
4097-00X
FRU Action
5 Printhead Cable / Disconnect the printer and check the carrier
Home Sensor printhead connector (J1). If the connection is
good, remove the printhead carrier and rod,
without disconnecting the printhead cables. Insert
a piece of paper into the sensor. Plug in the printer
and check for 5 V dc at connection (C) located on
the rear of the sensor. The voltage drops when
paper is removed. If voltage does not change
when paper is removed, replace the home position
sensor. If the problem remains, replace the system
board.
6 Maintenance A problem with the maintenance station can cause
Station carrier movement problems at the right margin. Go
to the Maintenance Station Service Check on
page 2-7.
7 Access Cover If the carrier does not move toward the cartridge
Sensor load position when the access cover is opened,
verify that power is on. If the carrier still does not
move, check the actuator arm for binds. If the arm
is working correctly, replace the system board.
2-6 Service Manual
4097-00X
Maintenance Station Service Check
The maintenance station has two functions:
1. Cleans the printhead nozzles during the print operation.
2. Seals the printhead when it is not being used to prevent the
nozzles from drying.
FRU Action
1 Maintenance As the carrier moves to the right over the
Station Assembly maintenance station, a slot on the bottom of the
carrier engages a tab on the sled of the
maintenance station causing the cap to rise and
seal the printhead. Carrier movement to the left
uncaps the printhead. The wiper cleans the
printhead nozzles as the carrier leaves the
maintenance station. The wiper cleans the
printhead only when the carrier is moving to the
left. There should be no wiping action of the
printhead nozzles when the carrier is moving to
the right. After the cleaning operation is complete,
a tab on the maintenance station engages a tab on
the carrier, causing the wiper to lower.
Check the maintenance station for worn or broken
parts.
2 Wiper Worn wipers cause degraded print quality just after
a maintenance cleaning. Check for loose or worn
wipers.
3 Cap Worn caps cause the printhead nozzles to dry and
clog. Check for loose or worn caps.
Diagnostic Information 2-7

If your machine does not have paper jam problems, continue with
the service check. If your machine does have a paper jam problem,
examine it for the following before you begin the service check:
" Check the entire paper path for obstructions.
" Be sure there is not too much paper in the sheet feeder.
" Be sure the correct type of paper is being used.
" Check for static in the paper.
FRU Action
1 System Board Unplug the printer and disconnect the paperfeed
motor (J3) from the system board. Plug the printer
in and check for approximately 9 - 12 V dc
between (J3-1) and ground and (J3-2) and ground
on the system board. If the voltage is not present,
check for motor pins shorted to the motor housing.
If you find a shorted pin, replace the motor. If you
still have a failure after replacing the motor,
replace the system board.
2-8 Service Manual
4097-00X

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.
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 machine.
" 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 machine.
" 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 machine cover or on a
metal table; if you need to put down the ESD-sensitive part for any
reason, first put it into its special bag.
" Machine 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 machine covers when you are not working on the
machine, 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-sensitive parts when cold weather
heating is used because low humidity increases static electricity.
