Cassette Size Detection/Cassette Detection - Canon PF-B1 Service Manual

Cassette Size Detection/Cassette Detection

Cassette paper size detection and cassette detection of the Paper Feeder are performed in the same way as the printer.
The Media Size Switch detects the size of paper being loaded and presence/absence of a cassette.
The switch consists of 3 microswitches, and the width is detected in accordance with the combination of ON/OFF.
For combination of the switches, see the table shown below.
When the cassette presence/paper size is changed, the DC Controller notifies the Main Controller of the status change.
