■ Cassette Pickup Assembly
● Overview
Paper inside a cassette is lifted up by the Lifter Plate.
The Lifter Plate rises by the rotation of the Cassette 1 Lifter Motor (M11). When the Pickup
Roller comes in contact with the surface of paper, paper is picked up by rotation of the
Cassette 1_Multi-purpose Tray Pickup Motor (M05), and only a single sheet of paper is
moved to the feed path by the Cassette Feed Roller and the Cassette Separation Roller.
Then, it is moved from the Pre-registration Roller to the Registration Roller by the rotation of
the Pre-registration Motor (M06).
If the Cassette 1 Pickup Sensor (PS05) 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 Cassette 1 Pickup Roller, the Cassette 1 Feed Roller and Cassette 1 separation
Roller are driven by the Cassette 1_Multi-purpose Tray Pickup Motor (M05) while the Pre-
registration Roller is moved by the rotation of the Pre-registration Motor (M06).

Tray Pickup Motor (M05) is suspended once, and the pickup operation is executed again.
