Paper Feed and Separation

The paper feed unit employs an RF system.

In a conventional FRR system, double feed of paper is prevented by reverse rotation of the separating

roller.

However, paper separation of the RF system is assisted by the resistance of a friction roller [A] with a

torque limiter (reverse drive is not performed).

When the paper feed tray is set in the machine, the tray bottom plate is lifted up, and the pick-up roller

[B] contacts the top of the stuck paper.

When the transport motor (M1) [C] and the paper feed clutch (CL1) [D] is switched ON, the rollers

rotate, and then the paper is supplied to the mainframe by the paper feed roller [E] and vertical

transport roller [F].

The paper feed sensor [G] detects the leading edge and trailing edge of the paper to control the feed

timing and determine a paper jam.

The roller holder functions as a paper guide and roller clip ring. The roller holder prevents the paper

from winding up.
