COPYRIGHT © 2001 CANON INC. CANON CLC1000/1000S/3100 REV.2 MAY 2001 PRINTED IN JAPAN (IMPRIME AU JAPON) 3-1273. OPERATION AND TIMINGVI. PICK-UP/FEEDING ASSEMBLYA. OutlineThe CLC1000 uses center reference for feeding paper, i.e., paper moves along the center of the pick-up/feeding path.The pick-up system includes cassette 1, cassette 2, multifeeder, and holding tray (duplexing unit). (Forthe paper deck, see “C. Paper Deck.”)Paper from a cassette or the multifeeder is controlled by the registration roller so that its leading edgeand the leading edge of the image on the photosensitive drum match and is then sent to the transfer belt.Upon reaching the transfer belt, the paper is retained against the transfer belt by the work of the chargesfrom the transfer blade; then, transfer of the first color (Y) occurs.When transfer of the fourth color ends, the paper is moved through the separation, feeding, and fixingassemblies to reach the copy tray (Figure 3-601).The microprocessor on the DC controller PCB generates the image leading edge signal (ITOP) as soonas the registration roller turns on, and the signal is used for reading image data from the memory PCB.
