4.17 Inductive sensors - Adjustment
This Printer uses inductive sensors in three places. One for the Beam wheel on the lower shaft, and two
are controlling the movement of the paper feed mechanism.
It is possible to check if the inductive sensors are functioning, by looking at the rear end where the
cable enters the sensor. Inside the sensor is a tiny LED lamp that will light up if a magnetic object is in
front of the sensor. The light comes out through some transparent plastic around the cable.
So by having the power turned on, and at the same time turning the shafts, the light should go on and
off.
The sensors can also be tested if you open the menu choice Main Menu - Warning - Service/Diagnostic
- Test Sensors.
When replacing/adjusting the sensors, the gap between the timing wheel and the sensors should be
maximum 0.6 mm. See gure below.
