The operational sequence of the cassette lift-up is as follows:
1. The lifter motor rotates to raise the lifter.
2. When the cassette media-stack surface sensor detects the surface of the paper stack, the lifter
motor stops.
3. The lifter motor rotates again when the cassette media-stack surface sensor detects that the paper
surface is lowered during a print operation.
The paper deck controller PCA determines a lifter motor failure when the cassette media-stack surface
sensor does not detect the stack surface within a specified period after the lifter motor starts rotating.

The paper deck controller detects the presence of paper in the cassette by monitoring the paper deck
cassette media-out sensor during the following periods.
●
When the product power is turned on, until the power is turned off (except during sleep mode).
●
During the lift-up operation.
The paper deck controller determines a media-out condition when the paper deck cassette media-out
