2-1-1 Paper feed/conveying section

Paper feed/conveying section consists of the paper feed unit that feeds paper from the paper cassette and the MP tray
paper feed unit that feeds paper from the MP tray, and the conveying section that conveys the fed paper to the transfer/
separation section.

(1) Paper feed section/paper cassette

Paper cassette is the universal type that is applicable to various paper sizes by adjusting the paper guides and stopper
and approximate 250 pages can be put in.
Mechanism in the paper cassette consists of the cassette actuator board that lifts the paper in order to let it touch the
pickup roller and the retard roller that prevents papers from multiple feeding. Paper that is drawn out by the rotation of
pickup roller of the paper feed unit is then sent in between the feed roller and the retard roller. Function of the built-in
torque limiter in the retard roller gives weak resistance force against the rotation. Normally, when only a page is drawn
out by the rotation of pickup roller, the paper is conveyed to the printer by the rotation of feed roller on its own. If the
pickup roller drew out two lapped pages somewhy, the upper paper is conveyed by the feed roller and the lower paper
stays due to the rotation resistant force of the retard roller because the friction force between papers is smaller than the
rotation resistance force of the retard roller and then the multiple paper feed can be prevented.
