CHAPTER 5 PICK-UP/FEEDING SYSTEM 5. Controlling the Single-feeder Pickup Roller The single-feeder pickup roller is controlled by the pickup clutch solenoid (SL1) and the single-feeder paper sensor (PS5). When copy paper is inserted into the single-feeder, the single-feeder paper sensor turns on and the main motor starts to rotate. The drive of the main motor reaches the signal feeder pickup roller through a gear. When the single-feeder pickup roller starts to rotate, copy paper is picked up from the signal feeder and is sent as far as the registration roller, which controls the paper so that its leading edge will match the leading edge of the image on the photosensitive drum.
