Lifter Movement - Canon CLC 1120 Service Manual

B. Lifter Movement
1. Outline
When the cassette is slid into the copier, the pickup roller lowers, and the light-blocking plate
leaves the lifter position sensor.
This condition turns on the lifter motor and, as a result, the lifter moves up. The lifter motor
stops when the lifter position sensor detects the top surface of the stack of copy paper on the lifter.
If the lifter position sensor does not turn on within a specific period of time after the lifter
motor has turned on, the copier will indicate 'E040' on its control panel.

Table 7-204 shows the lifter motor, lifter position sensor, and paper sensor used for each
cassette.
The CLC1120's pickup system is identical to that of the CLC1130 except that it does not have
the cassette 3. See the construction of the CLC1130.
