Table 1-14 Paper deck pickup-and-feed operation components (continued) Paper deck cassette media-size detection and cassette-presence detection The paper deck controller detects the size of paper loaded in the cassette and also whether the cassette is installed to the paper deck by monitoring the PD cassette media width switch and the PD cassette media end switch. The PD cassette media width switch and the PD cassette media end switch contain three subswitches each. The paper deck controller detects the size of paper and the presence of cassette according to the combination of the sub-switches and notifies the formatter.
The cassette media-size detection and the cassette-presence detection are not performed during Sleep mode.
