CHAPTER 8 PAPER DECK-L1
8-1 P
1.1 Pickup

1.1.1 Outline

The paper deck (hereafter, “deck”) is capable of accommodating as many as 2500 sheets
(A4/LTR, B5; 80 g/m2 paper) at a time, and is designed to operate in response to control
signals from the DC controller of its host machine.
The lifter of the deck is driven by the deck lifter motor (M2D), and paper is picked up and
moved by the drive of the deck main motor (M1D).

1.1.2 Pickup Operation

The paper placed inside the deck is held up by the lifter, and is kept in a specific pickup
position.
When the Start key is pressed and the deck pickup clutch (CL2D) goes ON, the drive of
the deck main motor (M1D) rotates the pickup roller to pick up paper; at this time, the
pickup/feeding roller and the separation roller serve to make sure that only one sheet of pa-
per is moved forward. When the deck pickup sensor (PS1D) detects paper thereafter, the
deck pickup roller releasing solenoid (SL1D) goes ON so that the pickup roller leaves the
stack of paper.
The deck feeding roller starts to rotate when the deck feeding clutch (CL1D) goes ON.
The picked paper is moved to the registration roller of the host machine, and is made to arch
for removal of the slack.
The registration roller is controlled so that the leading edge of paper will match the image
on the photosensitive drum.
