Cassette 1 Right Door Detecting Sensor (PC23)
This sensor detects whether the Cassette 1 right door is closed or not. The sensor uses a photointerrupter. The right door is normally closed except when removing jammed paper.
When the right door is closed:
The projection of the side door engages with the photointerrupter of the Cassette 1. Thus, the output of the
photointerrupter is “H”.
When the right door is opened:
The projection of the side door comes off the photointerrupter. Thus, the output of the photointerrupter is “L”.
