	FRU	Action
2	Paper Feed Motor	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 paper feed mechanism
		With the paper feed motor cable CN7
		disconnected from the system board, check for
		approximately 4 ohms between the following pins
		on the motor:
		Pin 1 to Pin 4
		If the readings are incorrect, replace the paper
		feed motor assembly with gears. Go to the “Paper
		feed motor assembly with gears removal” on
		page 4-23.
		Although the paper feeds in a forward direction
		only, the paper feed motor turns in two directions.
		If the paper feed motor turns in one direction only,
		replace the system board. Go to the “System
		board removal” on page 4-19.
		Binds in the paper feed motor or gear train can
		cause intermittent false paper jam errors. Remove
		the paper feed motor and check the shaft for binds.
		Also check for a loose or worn motor gear.
