The low friction force between the sheets weakens the driving force from the cassette feed roller.
Therefore, the separation roller is driven by its own driving force and holds back any multiple-fed sheets
from the cassette.

The product picks up one sheet of paper from the MP tray.
The sequence of steps for the multipurpose tray pickup operation as follows:
1. The pickup motor reverses when a print command is received from the formatter.
2. When the DC controller turns on the MP tray pickup solenoid, the MP tray pickup roller rotates and
the lifting plate lifts.
3. As the lifting plate rises, the paper is picked up.
4. The multipurpose tray separation pad removes any multiple-fed sheets, and one sheet is fed into
the product.
