3. Detecting Copy PaperCopy paper (last sheet) is detected for re-pick up from the holding tray.When copy paper has been stacked on the holding tray, the holding tray re-circulat-ing motor (M7) is driven to place the re-circulating lever on the top sheet of the stack.When the last sheet is picked up, the re-circulating lever falls through the holding tray,allowing the holding tray re-circulating lever home position sensor (PS19) to assume thatthe last sheet has been picked up and to generate the last sheet detection signal(HPLPD).Figure 5-617Holding trayre-circulating motor (M7)Copy paperRe-circulating leverHolding tray re-circulatinglever home position sensor (PS19)COPYRIGHT © 1997 CANON INC.
