6-5. Paper Size Detecting Mechanism

• Both the width (in the crosswise direction) and length (in the feeding direction) of the
paper are detected and the copier CPU determines the paper size based on the combi­nation of the two readings.

• The width (CD) of the paper is detected when the lever that is operatively connected to
the Edge Guide activates or deactivates the Paper Size (CD) Detection Sensor.

• The length (FD) of the paper is detected when the lever that is operatively connected to
the Trailing Edge Stop actuates or deactuates the switches on the Paper Size (FD)
Detection Board.

6-6. Paper Separating Mecha nism

• A loop is formed in the paper between the Separator Fingers and the Paper Take-Up
Roller. The turning force of the P aper Take-Up Roller overcomes the block of the Separa­tor Fingers, causing the top sheet 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 Lift­ing Plate is low, the bottom sheet of paper is taken up and fed into the copier with the top
sheet of paper. To prevent this situation from occurring, there is a Friction Plate provided
on top of the Paper Lifting Plate.

• Before the Paper Take-Up Roller contacts the paper, the Paper Take-Up Roll holds the
paper down so that the paper remains stationary before its being taken up by the Paper
Take-Up Roller.

6-8. Paper Take-Up Retry Control

• To minimize the occurrence of paper misfeed, the Paper Take-Up Solenoid is energized a
second time to carry out a paper take-up retry sequence if a sheet of paper fails to reach
the Synchronizing Roller Sensor (for the 2nd Tray) or the Paper Take-Up Sensor (for the
3rd to 5th Tra y) within a giv en period of time after a paper tak e-up sequence has been ini­tiated. This sequence is repeated a predetermined number of times.
