Bypass tray

[A] Operation of drawer pickup roller
When a paper is set on the bypass tray, the bypass sensor (S8) detects it and judges that there is paper
on the bypass tray, and the bypass feeding is performed in preference to drawer feeding.
When the bypass pickup solenoid (SOL1) is turned ON, the driving force of the main motor (M4) is
transmitted to the bypass pickup clutch and bypass feed clutch. The bypass pickup roller starts to be
rotated and lifted down by the drive from the bypass pickup clutch, and the paper on the bypass tray is
transported to the bypass feed roller.
[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 more than two sheets of paper are fed from the bypass
pickup roller, since the friction between two sheets of paper is smaller than that of between a sheet and
the separation pad, the lower sheets are not transported any further while the uppermost paper is trans-
ported by the feed roller.
The paper transported by the bypass feed roller reaches the registration roller. After the paper is
aligned with 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.
