3.3.1 Plate-up Function of the Paper Tray
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 pressure to the feed roller and to give the paper feeding
performance.
When the paper tray (Tray1 cassette) is installed to the machine, the plate is lowered.
If the main motor drives in this situation, the driving reaches the lift gear 46 through some
gears. This driving also reaches the plate up plate and it pushes up on the plate ASSY.
Fig. 2-19
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.
Fig. 2-20
When the tray is pulled out from the machine, the pressure plate is returned to the original
position. When the tray is put into the machine, the above operation is performed from the
start again.
