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.
