Inductive sensors - adjustment
This printer uses inductive sensors in three places. One for the main timing wheel on the lower shaft,
and two are controlling the movement on 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 little LED lamp that will be lit if a magnetic object is in
front of the sensor. So by having the power turned on, and at the same time turning the shafts, the
light should go on and off.
When replacing/adjusting the sensors, the gap between the timing wheel and the sensors can be
maximum 0.6 mm. Check this for the whole revolution of the timing See figure below.
