500-sheet paper feeder cassette media-size detection and cassette-presence
detection
The paper feeder controller determines the size of paper loaded in the cassette and also whether the
cassette is installed to the paper feeder by monitoring the PF cassette media width switch and the PF
cassette media end switch.
The PF cassette media width switch and the PF cassette media end switch contain three sub-switches
each. The paper feeder controller detects the size of paper and the presence of cassette according to
the combination of the sub-switches and notifies the formatter.
