4.5 PULL TRACTOR SENSOR POSITION ADJUSTMENT

Perform this adjustment when you replace or disassemble the platen, rear paper guide, platen roller shaft,
tension roller shaft, or pull tractor sensor. If the sensor position is incorrect, the sensor is always on. Figure
4-4 illustrates the pull tractor sensor position adjustment.
When you assemble the pull tractor sensor or rear paper guide, make sure:


The pull tractor sensor lever is touching the rear paper guide frame, but the sensor is off.


The distance between the sensor lever and sensor switch is approximately .08 inch (2 mm).
