Cassette paper size and presence detection
The device detects the size of the paper that is loaded in the cassette and the presence of the cassette.
The DC controller monitors the on/off status of the paper-width and paper-length detection switches.
The switches are interlocked with the paper side and rear-limit plates. The switches are functioning when
the cassette is installed. The DC controller detects the paper size and the cassette presence according
to the switch status.
