■ Cassette Pickup Assembly

● Overview
Paper inside a cassette is lifted up by the Lifting Plate.
When pickup takes place, the Cassette Pickup Solenoid (SL1) is turned ON so that the
Pickup Roller is moved down. When the Pickup Roller comes in contact with the surface of
paper, the paper is picked up by rotation of the roller.
Only a single paper picked up is moved to the feed path by the Feed Roller and the
Separation Roller, and moved as far as the Registration Roller by the Vertical Path Roller.
If the Cassette Pickup Sensor (PS13) is ON when starting pickup (in the case that the
succeeding paper is also picked up when a paper is picked up and fed), the feed speed is
decreased.
The Vertical Path Roller, Pickup Roller, Feed Roller, and Separation Roller are driven by the
Cassette Pickup Motor (M8).
