1. Outline
The paper deck (hereafter, “deck”) is capable of accommodating as many as 2500 sheets of
paper (A4, LTR, B5; 105 g/m
2
) at one time, and is designed to feed paper in response to control
signals from its host copier’s DC-CPU.
The lifter of the deck is driven by the deck lifter motor (M101), and the deck picks up and feeds
paper using the drive from the deck pickup motor (PM101).
2. Pickup Operations
The paper set in the deck is lifted by the lifter, and held to a specific pickup position by the
lifter.
When the Start key is pressed and, as a result, the deck pickup clutch (CL102) turns on, the
drive of the deck pickup motor (PM101) rotates the pickup roller to pick up paper. At this time, the
pickup/feed roller and the separation roller make sure that only one sheet of paper is picked up;
then, when the deck pickup sensor (PS101) detects the paper, the deck pickup solenoid (SL101)
turns on to move the pickup roller away from the surface of the paper.
The paper is then moved to the copier’s registration roller and made to arch for removal of any
skew. The registration roller controls the paper so that its leading edge will match the image on the
photosensitive drum.
