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.
