CHAPTER 5 PICK-UP/FEEDING SYSTEMCOPYRIGHT © 1999 CANON INC. CANON NP6317 REV.0 APR. 1999 PRINTED IN JAPAN (IMPRIME AU JAPON) 5-1I. PAPER PICK-UP ASSEMBLY AND FEEDERA. OutlineWhen the pick-up clutch solenoid (SL1) engages, main motor (M1) turns the roller, feeding asheet of copy paper to the registration rollers. The number of rotations of the pick-up roller varieswith the length of the copy paper.The copy paper is fed by the registration rollers so that its leading edge is in line with theleading edge of the toner image on the photosensitive drum. It then passes through the transfer,separation, feed, fixing and delivery stages to the copy tray.The copy paper is sensed by paper sensor (Q2 and Q5). If it does not reach or pass the sensorswithin the specified period, the DC controller PCB judges that a jam has occurred and causes theJAM indicator on the control panel to flash.The cassette paper sensor (Q11) senses whether there is paper in the cassette. If there is not, theCASSETTE PAPER EMPTY signal (CPEP) goes '0', causing the ADD PAPER indicator on thecontrol panel to go ON.Figure 5-101Pick-up rollerSL1Control ring
