Pick-Up From The Multifeeder - Canon NP6320 Service Manual

Pick-Up from the Multifeeder

The multifeeder pick-up roller is driven by the main motor (M1).
When the multifeeder paper sensor (Q1) identifies copy paper and the Copy Start key is
pressed, the multifeeder clutch (CL2) goes ON and the pick-up roller starts to rotate to pick up the
paper.
When the copy paper reaches the registration roller, the multifeeder clutch (CL2) goes OFF
and the pick-up roller stops.
At the same time, the multifeeder solenoid (SL3) goes ON to transmit the drive of the main
motor (M1) to the cam mechanism, thereby lowering the multi-feeder holding tray to prevent dirt
on the next copy paper in the multifeeder tray.
The multifeeder solenoid (SL3) goes OFF as soon as the first copy paper moves past the pre-
registration paper sensor (Q2); at the time, the multifeeder holding tray returns to the normal pick-
up position.
Note:
The degree of arching for pick-ups from the multifeeder may be adjusted in the service mode
(C04).
