PAPER FEEDING SYSTEM
10 - 8
[B] Paper separation
This model is equipped with a separation pad which works to prevent multiple paper feeding. The sepa-
ration pad is pushed to the bypass feed roller by the spring force. The bypass feed roller is rotated syn-
chronously with the bypass pickup roller. When two or more sheets of paper are fed from the bypass
pickup roller, since the friction between two sheets of paper is smaller than that between a sheet and
the separation pad, the lower sheets are not transported any further while the uppermost one is trans-
ported by the feed roller.
The paper transported by the bypass feed roller reaches the registration roller. After the paper is
aligned by the registration roller, the bypass pickup solenoid (SOL2) is turned OFF to stop the bypass
pickup roller and bypass feed roller, and the bypass pickup roller returns to its original position.
