2-1-1 Paper feed section
Paper feed 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 paper feed conveying section that conveys the fed paper to the transfer/
separation section.
(1) Paper cassette paper feeding
Paper cassette is the universal type that is applicable to various paper sizes by adjusting the side guides and paper stop-
per and approximate 250 pages can be put in. Mechanism in the paper cassette consists of the bottom plate 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 cassette paper feed section 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 rota-
tion. 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 someway, 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.
