Pickup/Feed Control - Canon PF-B1 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 through the Pickup Motor (M101) of the printer 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 Pickup Motor (M101).
3. The PF Pickup Roller, PF Feed Roller and PF Feed Roller 1 start to pick up paper by operating the PF Pickup Solenoid
(SL1600).
The following shows an outline drawing of the electrical components and a list of electrical components.
