C. Detecting the Presence/Absence of Paper in the Deck1. Detecting the Presence/Absence of Paper in the DeckThe presence/absence of paper inside the deck is detected as follows by the deckpaper sensor (PS32/PS35).When the deck runs out of paper, the paper detecting lever leaves the paper sensor(PS32/PS35), causing the DC controller PCB to assume the absence of paper.Figure 5-307 (paper present)Figure 5-308 (paper absent)2. Detecting the Size of the DeckThe service person is expected to enter the deck size.D. High-Speed Pick-UpWhen pick-up occurs from the right deck, the pick-up motor (M2) rotates at a highspeed when picking up the first sheet so as to save on the first copy time; the period ofhigh-speed rotation is as follows:• After the first sheet has reached the pick-up vertical path sensor 0 (PS24) and until itarches against the registration roller.The rate of high-speed rotation is about twice the speed of normal rotation.Paper sensor Paper detecting leverPaper sensor Paper detecting leverCHAPTER 5 PICK-UP/FEEDING SYSTEM5-19COPYRIGHT © 1997 CANON INC.
