C. Detecting the Presence/Absence of Paper in the Deck

1. Detecting the Presence/Absence of Paper in the Deck

The presence/absence of paper inside the deck is detected as follows by the deck
paper 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.

2. Detecting the Size of the Deck

The service person is expected to enter the deck size.
D. High-Speed Pick-Up
When pick-up occurs from the right deck, the pick-up motor (M2) rotates at a high
speed when picking up the first sheet so as to save on the first copy time; the period of
high-speed rotation is as follows:
• After the first sheet has reached the pick-up vertical path sensor 0 (PS24) and until it
arches against the registration roller.
The rate of high-speed rotation is about twice the speed of normal rotation.
