Pull Tractor Sensor Service Check
Note: The pull tractor sensor detects the tractor in the pull position
and disables park/load and auto tear-off. A failed sensor may
prevent park/load from functioning with the tractor in the push
position.

Pull Tractor
Sensor
With the tractor in the push position, press
Alt+Park/Load several times while alternately
holding down and releasing the left pull tractor
actuator. The paper should park and load when
the actuator is not held down, and should not
park or load when the pull tractor actuator is
held down.
If the paper does not move correctly:
• Disconnect CN4 from the main logic
board.
• There should be 0 ohms from
CP4-1 to CP4-2 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 main logic board.
• Reset the Bidirectional Alignment, see
“Bidirectional Print Adjustment” on page
4-5.
