Pickup/Feed Control - Canon PF-D1 Service Manual

Pickup/Feed Control

Pickup/feed control of the Paper Feeder uses the same mechanism as printer.
Rollers in the Paper Feeder are operated by the PF Feed Motor (M20) via gears.
Pickup/feed control sequence of the Paper Feeder is shown below:
1. Lift-up operation is performed when power is turned ON or the door is closed to lift up the Lifter Plate to a position where
paper can be picked up.
2. The DC Controller receives the print start command and drives the PF Feed Motor (M20).
3. The PF Pickup/PF Feed Rollers start to feed paper by operating the PF Pickup Clutch (CL20).
The following shows an outline drawing of the electrical components and a list of electrical components.
