Paper-feeder cassette lift operation
The paper feeder keeps the paper stack surface at the correct pickup position. The cassette lift operation
occurs under the following conditions:
●
The product is turned on.
●
The cassette is inserted.
●
The paper stack surface of the cassette lowers.
The sequence occurs as follows:
1. The PD lifter motor rotates and the lifter moves up.
2. When the tray media-stack-surface sensor detects the stack surface of the paper, the PD lifter
motor stops.
3. The PD lifter motor rotates again to lift the lifter when the PD cassette media-stack-surface sensor
detects the stack surface, and then lowers during printing.
If a tray media-stack-surface sensor does not detect a stack surface within a specified period after the
PD lifter motor starts rotating, the paper feeder driver determines that the PD lifter motor has failed and
through the DC controller notifies the formatter.

The paper-feeder driver notifies the formatter if either of the paper-feeder media-stack surface sensors
fails to detect the stack surface within a specified period from when a lift-up operation starts.
