CHAPTER 5 PICK-UP/FEEDING SYSTEMCOPYRIGHT © 1999 CANON INC. CANON NP6317 REV.0 APR. 1999 PRINTED IN JAPAN (IMPRIME AU JAPON) 5-5D. Pick-Up from the MultifeederThe multifeeder pick-up roller and holding plate are driven by the main motor (M1). The pres-ence/absence of paper is monitored by the multifeeder paper sensor (Q1).When the Copy Start key is pressed, the multifeeder solenoid (SL3) turns on temporarily,causing the claw 1 to disengage from the control ring. When the multifeeder pick-up roller rotates,the holding plate starts to move up; the pick-up roller continues to rotate even after the multifeedersolenoid turns off.A specific time (Note 1) after the leading edge of paper has reached the pre-registration sensor,the multifeeder solenoid turns on once again, causing the claw 2 to engage with the control ringgear and, ultimately, stopping the control ring.The multifeeder solenoid turns off once again as soon as the registration roller starts to rotate.This causes the claw 2 to disengage from the control ring gear. When the multifeeder pick-up rollerrotates, the holding plate starts to move down. When the control ring makes a full turn, the claw 1engages with the control ring to stop the ring.Note 1:May be varied using 'C4' of service mode.Figure 5-104Lifter plateLifter plateLifter plateMultifeederpick-up rollerMultifeederMultifeedersolenoid (SL3)Claw 2Claw 1Control ringCamCamView A A
