Action
Check the motor for binds,or loose motor pulley.
Turn the printer off and disconnect CN2 from the system board.Check
for motor pins shorted to the motor housing.If you find a pin shorted to
the housing,replace the motor. If the failure remains,replace the system
board.
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:
CN2-1 and CN2-2
CN2-3 and CN2-4
If the readings are incorrect,replace the motor.
Clean the carrier rod.
Note:Lubricate the carrier guide rod and the carrier rod bearing surface
with grease.
Check for worn,loose or broken parts. Check for obstructions blocking
carrier movement.
Carrier to carrier frame engagement should be lubricated with grease.
Be sure the carrier returns to the home position after turning the printer
on. If the carrier moves half way,or if there is an abnormal sound,turn
the printer off and disconnect CN3 from the system board. Turn the
printer on and check for 5V dc between CN3-4 and CN3-2 on the
system board. If the voltage is present,replace the home position
sensor. If the voltage is not present,replace the system board.
A problem with the maintenance station can cause carrier movement
problems at the right margin. Go to the 'Maintenance Station Service
Check' on page 3.
