Cassette pickup
The sequence of steps for the cassette-tray pickup operation is the following:
1. When the product starts or the tray closes, the lifting mechanism lifts the paper stack so it is ready.
2. After receiving a print command from the formatter, the DC controller rotates the pickup motor,
which causes the cassette pickup roller, cassette feed roller, and cassette separation roller to
rotate.
3. The DC controller drives the cassette pickup solenoid, which rotates the cassette pickup cam. As
the pickup cam rotates, the pickup arm moves down, and the cassette pickup roller touches the
surface of the paper stack. The cassette pickup roller then picks up one sheet of paper.

NOTE: The lift-up operation lifts the lifting plate to keep the stack surface of the media at a pickup
position. The lifting spring helps support the lifting plate depending on the media size and amount.
