Pickup/feed operation
The HCI operation picks up paper in the cassette one sheet at a time and feeds it to the device. This
section describes the pickup/feed operation for the 1 x 500-sheet HCI and the top cassette of the 3 x 500-
sheet HCI. The pickup/feed operation for the center and bottom cassettes of the 3 x 500-sheet HCI is
the same as the top cassette.

●
The DC controller operates the HCI driver PCA when it receives a print command from the
formatter.
●
The HCI driver PCA performs the pickup/feed operation for the HCI. The PCA picks up the paper
and feeds it to the device entrance.
The following table lists the assigned electrical component codes for the 1 x 500-sheet HCI cassette
and the 3 x 500-sheet HCI cassettes.
