CHAPTER 10 PAPER DECK
B. Pickup

1. Outline

The paper deck (hereafter, "deck") is capable of accommodating as many as 2500 sheets of
copy paper (A4, LTR, B5; 105 g/m2) at one time, and is designed to feed copy 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
copy paper using the drive from the deck pickup motor (PM101).

2. Pickup Operations

The copy paper set in the deck is lifted by the lifter, and held to a specific pickup position by the
lifter.
When the Copy 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 cop paper. At this
time, the pickup/feed roller and the separation roller make sure that only one sheet of copy paper is
picked up; then, when the deck pickup sensor (PS101) detects the copy paper, the deck pickup
solenoid (SL101) turns on to move the pickup roller away from the surface of the copy paper.
The copy paper is then moved to the copier's registration roller and made to arch for removal of
any skew. The registration roller controls the copy paper so that its leading edge will match the
image on the photosensitive drum.
