HCI cassette media-size detection and cassette-presence detection

The HCI controller detects the size of paper loaded in the cassette by monitoring the HCI cassette
media size sensors. It determines whether A4-R or Letter-R is loaded and notifies the formatter through
the DC controller. It also detects whether the cassette is installed to the 3,500-sheet paper deck by
monitoring the HCI cassette open detection switches and notifies the formatter through the DC
controller.
The cassette media-size detection and the cassette-presence detection are not performed during Sleep
mode.
