Diagnostic Information

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.

Carrier Transport 
Motor

Check the motor for binds, or loose motor pulley.

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.
