Table 1-18 HCI pickup-and-feed operation components (continued) 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.
