C. Lifter Operation1. OperationWhen the deck is slid inside the pedestal, the pick-up roller lowers and the light-blocking plate leaves the deck lifter position sensor (PS5). The condition causes the lifterdrive clutch (CL4) to turn on, and the drive of the pedestal motor (M1) is transmitted tothe cable take-up shaft, thereby raising the lifter.The lifter keeps rising until the deck lifter position sensor (PS5) detects the top sheetof the paper stack placed on the lifter.The deck lifter upper limit sensor (PS6) serves to stop the lifter in the event that thesensor arm should block the deck lifter position sensor (PS5) for some reason.When the lifter has reached its upper limit, it is maintained in position by the work ofa one-way gear.When the deck is removed from the pedestal, the take-up gear disengages itself fromthe one-way gear, thereby allowing the lifter to lower on its own weight.Figure 8-404CHAPTER 8 PAPER DECK PEDESTALCOPYRIGHT © 1997 CANON INC.
