Bypass Feed Paper Size Detection
Paper size width detection is performed by the bypass width sensor (rotary switch).
The bypass feed size switch has a rotation plate which rotates together with the side fence of the bypass feed table, and detects the paper size.
Paper portrait/landscape is determined by the length sensor.
Two feelers [A] for the bypass length sensor [B] are added to the rear of the tray to prevent false detection of paper length caused by floating at the rear of paper when long paper is set without pulling out the bypass tray extension.
Bypass Feed Paper End Detection
To detect bypass feed paper end, a paper detection feeler and bypass feed paper end sensor are provided.
When the paper is set, the bypass feed paper end sensor switches ON (interrupt), and paper set is detected.
When there is no more paper, the detection feeler falls into a hole in the bypass feed table, the bypass feed paper end sensor switches OFF (pass), and paper end is detected.
Bypass Paper Feeder Drive
The paper feed roller, Reverse roller and pick-up roller are driven by the bypass/duplex motor.
