(4) 2nd Cassette Side Door Detecting Sensor (PC23)
This sensor detects whether the 2nd cassette side door is closed or not. The sensor uses a photointerrupter. The side
door is normally closed except when removing jammed paper.
When the side door is closed, the projection of the side door engages with the photointerrupter of the 2nd paper cassette.
Since the light emitted from the LED of the photointerrupter is blocked by the projection, the photointerrupter turns OFF.
Thus, the output of the photointerrupter is “H”.
When the side door is opened, the projection of the side door comes off the photointerrupter. Thus, the light from the LED
passes in the photointerrupter and the photointerrupter turns ON. Thus, the output of the photointerrupter is “L”.
(5) 2nd Cassette Paper Size Detection
The paper size for the 2nd paper cassette is set by the switch on the 2nd cassette paper size detecting board (PWB-S2).
The switch is a rotary encoder with four output lines. The output levels of the four output lines vary with the rotational
angles of the switch. These four outputs are fed to the control circuit on the main board and decoded to detect the paper
size being selected.
