Controlling The Attraction Mechanism - Canon CLC 1120 Service Manual

CHAPTER 7 PICK-UP / FEEDING SYSTEM
C. Controlling the Attraction Mechanism
The copier's transfer drum is designed to retain copy paper on the transfer drum sheet using
static charges.
During copying operation, the attraction roller solenoid (SL6) remains on for a period of time
equal to the length of the copy paper to bring the attraction roller in contact with the transfer drum
sheet. At this time, the attraction brush turns on, causing the transfer drum sheet to attract the copy
paper.
Reference:
1. In the case of a mono-color copy, the copy paper is separated before the transfer drum
completes a full rotation. As such, SL6 remains on at all times without turning off.
2. In the case of retaining two sheets of paper, SL6 does not turn off between the first and
second sheets.
