Cassette 1 Right Door Detecting Sensor (PC23)
o
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:
n
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:
n
The projection of the side door comes off the photointerrupter.
Thus, the output of the photointerrupter is "L".
