D. Deck Lifter1. Lifter OperationThe lifter of the deck is connected to the reel by means of a cable, and is driven bythe deck lifter motor (M102). The lifter is moved up and down by switching the directionof the rotation of the motor.When the deck (compartment) is pushed into the copier, the deck OPEN switch(SW102) is pushed, and the lifter moves up. Then, the lifter stops when the deck lifterposition sensor (Q110) detects the top surface of the copy paper stacked on the lifter.In consideration of such faults as when the deck fails to stop moving up after thesensor lever has blocked the deck lifter position sensor, a deck lifter upper limit sensor(Q102) is provided to prevent damage to the deck.The lifter starts to move down when the deck OPEN switch (SW100) is pressed, andstops when it leaves the sensor lever of the deck paper supply position sensor (Q103),i.e., the falling edge of the sensor signal.When copy paper has been supplied in this position, the lever of the deck papersupply position sensor is pushed, and the lifter moves farther down until the copy papermoves away from the sensor lever.At this time, the lifter repeats moving down until the deck lifter lower limit switch(SW103) is pressed each time copy paper is supplied (maximum paper supply position).CHAPTER 8 PAPER DECK-A18-8 COPYRIGHT © 1997 CANON INC.
