8.5 Cassette Pick Up Unit

8.5.1 Overview

The paper inside the cassette is held up by the lifter so that the paper remains in contact with the pickup roller.
When the cassette pickup motor goes on, the pickup roller starts to rotate to pick up paper.
When the cassette solenoid goes on, on the other hand, the pickup roller starts to leave the surface of paper.
The feed roller and the separation roller make sure that only one sheet of paper is moved ahead to the feed path to
reach the vertical path roller.
The pickup roller, feed roller, and separation roller of the cassette 3/4 are driven by the cassette pickup motor (M19),
and its drive is switched from the cassette 3 pickup assembly to the cassette 4 pickup assembly by reversing the
rotation of the cassette pickup motor.
