Paper Feed/ Transport Section
The paper feed unit employs an RF system.
In a conventional FRR system, transport of 2 sheets at a time is prevented by reverse rotation of the
separating roller, but in the RF system, paper separation is assisted by the resistance of a separating
roller with a torque limiter (reverse drive is not performed).
When the paper feed tray is set in the machine, the pressure release lever is pressed, the Friction roller
comes in contact with the paper feed roller, and the pick-up roller contacts the top of the paper (to
prevent paper remaining, when the paper feed tray is withdrawn, the arm returns and contact with the
rollers is released).
The machine enters paper supply standby mode when the tray bottom plate moves up. When the paper
feed motor is switched ON, the rollers rotate and paper is supplied.
The roller holder functions as a paper guide and roller clip ring. The roller holder prevents the paper
from winding up.
