B. Pick-Up1. OutlineThe side paper deck (“deck” hereafter) is capable of accommodating 3,500 sheets ofcopy paper at once (A4, LTR, B5; 80 g/m 2 ), and picks up copy paper according to thecontrol signal from the copier’s DC controller PCB.The lifter of the deck is driven by the deck lifter motor (M102), and copy paper is fedusing the drive of the deck main motor (M101).2. Pick-Up OperationThe copy paper inside the deck is held up by a lifter and kept in place at a specificposition.When the Copy Start key is pressed and the deck pick-up clutch (CL102) turns on,the drive of the deck main motor (M101) rotates the pick-up roller to pick up copy paper.At this time, the feeding roller and the separation roller serve to make sure that onlyone sheet of copy paper is fed; thereafter, the deck pick-up roller releasing solenoid(SL101) turns on as soon as the deck paper sensor (Q107) detects copy paper, therebymoving the pick-up roller to move away from the surface of the copy paper.The deck vertical path roller starts to rotate when the deck vertical path clutch(CL101) turns on. The copy paper is then sent to the copier’s registration roller and madeto arch (so that it will not move askew).The registration roller controls the copy paper so that its leading edge matches theleading edge of the image on the photosensitive drum.COPYRIGHT © 1997 CANON INC.
