If your printer does have a paper jam, examine it for the following before you begin the service check: • Check the entire paper path for obstructions. • Be sure not to overfill the sheet feeder. • Be sure the correct type of paper is being used. • Check for static in the paper. Parts / FRUs 1 System Board Action Check for approximately +17 V dc pulse between paper feed connector J3F-4 and ground, on the system board as the paper feed motor is running during the POST sequence. If the voltage is incorrect, replace the system board. If correct, check for motor pins shorted to the motor housing. If you find a shorted pin, replace the engine frame assembly. 2-8 Service Manual
