Pull Tractor Sensor Service Check

The pull tractor sensor detects the tractor in the pull position and disables load/unload and auto tear-off. A failed sensor may prevent load/unload from functioning, with the tractor in the push position.

	FRU	Action
1	Pull Tractor	With the tractor in the push position, press
	Sensor	Load/Unload several times while alternately
		holding down and releasing the left pull tractor
		actuator. The paper should load and unload
		when the actuator is not held down, and should
		not load or unload when the pull tractor
		actuator is held down.
		If the paper does not move correctly,
		disconnect CN3 from the logic board.There
		should be continuity from CN3-1 and CN3-2
		when the left pull tractor actuator is pressed,
		and infinite resistance when the actuator is not
		pressed. Replace the sensor if necessary.
		If the sensor is good but the paper still does not
		move correctly, replace the logic board and
		reset the “Bidirectional Print Adjustment”
		on page 4-4.
