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
approximately12 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.

turncanbecausedby:
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.
Note: Lubricate the rod and the carrier rod bearing
surfaces with grease P/N 99A0394.

A problem with the maintenance station can cause
carrier movement problems at the right margin. Go
to the “Maintenance Station Service Check” on
page 2-7.
If the carrier does not move toward the cartridge
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.
