Feeding Paper from the Paper Tray
The paper loaded in the paper tray is transported towards the Feed Roller and Retard Roller by the
Nudger Roller and then transported towards the Turn Roller Assembly by the rotation of Feed Roller
and Retard Roller. The Nudger Roller and the Feed Roller rotate by the drive that is provided by the
Paper Handling Motor through the Feed Roller Clutch.
The Retard Roller is pushed by the spring pressure beneath it, and presses against the Feed Roller to
separate the paper by using rotation resistance.
When there is paper overlap, the brake force of the Torque Limiter that is linked to the Retard Roller
separates the top most paper from the rest and feeds it.
The Bottom Plate Assembly is a mechanism that works with the Gear attached to the side of the paper
tray. As long as the coupled Gear is not released, the device can maintain a specified position without
rising/descending. Paper is fed at this position.
When the top level of the paper stack drops as paper is being fed, the Nudger Roller descends, the
Lever releases the Gear, and the Bottom Plate Assembly rises.
