Paper Separating Mechanism

• A loop formed in the paper between the Separator Fingers and Paper Take-up Rollers.
The turning force of the Paper Take-up Rollers overcomes the block of the Separator Fin-
gers, causing the top of paper to ride over the fingers and be fed out of the tray into the
copier.
• When there are only two sheets of left in the tray and if the friction force of the Paper Lift-
ing Plate is low, the bottom sheets of paper is taken up and fed into the copier with the
top sheets of paper. To prevent this situation from occurring, there ia a Friction Plate pro-
vided on top of the Paper Lifting Plate.

Paper Empty Detection

• There is a Paper Empty Sensor provided on the 2nd Drawer Control Board. It detects a
paper empty condition of the cassette.
• When paper is loaded, the actuator is raised and blocks the sensor.
• If there is no paper loaded, the actuator drops in the hole in the Paper Lifting Plate, thus
unblocking the sensor.
