CHAPTER 2 THEORY OF OPERATION
The plate ASSY in the paper tray is pushed up with the motor drive and not with the spring in
order to maintain the constant paper feeding performance regardless the number of sheet
remained in the tray.
When the paper tray (Tray1 cassette) is installed into the printer, the lift gear 46 is rotated, and
the motor drive is transmitted to the plate ASSY so that it is pushed up.

When the feed roller is pushed up, the hook is released by the lift arm, and the rotation of the
clutch gear is stopped. Then, the pressure plate is stopped to push up.
When a paper jam occurs, the nips between the pressure roller and feed roller TR and
between the pinch roller and regist roller are released, which allows you to remove the jammed
recording paper easily.
