4.1.4 Pull Tractor Sensor Position Adjustment
This section describes the pull tractor sensor position adjustment. If the sensor position is incorrect, the
sensor is always on. When you replace or disassemble the platen, rear paper guide, platen roller shaft,
tension roller shaft, or pull tractor sensor, perform this adjustment. Figure 4-4 illustrates the pull tractor sensor
position adjustment.
When you assemble the pull tractor sensor or rear paper guide, check the following items:
•
Verify that the pull tractor sensor lever is touching the rear paper guide frame, but the sensor is
off.
•
Make sure the distance between the sensor lever and sensor switch is approximately 2 mm (.08
inches).
