Cassette media-size detection and cassette-presence detection
The paper feeder detects the size of the paper loaded in the paper feeder cassette by monitoring the paper
feeder cassette media end switch and the paper feeder cassette media width switch. It also detects the
presence of cassette by monitoring the switches. The paper feeder controller notifies the formatter through
the DC controller when it determines a cassette is absent.
