5.3.2 Cassette Lifter Operation

T02-503-02 shows an outline of the movement of the cassette lifter.
When the cassette is set in the copier, the pickup roller moves down, and the lifter detect-
ing lever leaves the lifter sensor.
This condition turns on the cassette lifter motor to move up the lifter. The cassette lifter
motor stops when the cassette lifter sensor reaches a position at which it can detect the top
surface of the stack of paper placed on the lifter.
When paper runs out and, as a result, the paper detecting lever leaves the cassette paper
sensor, the machine displays a message on its control panel to indicate the absence of paper.
The following shows the notations of the cassette lifter motor, cassette lifter sensor, and
cassette paper sensor used in the machine's cassette 1 and cassette 2.
