CHAPTER 5 PICK-UP/FEEDING SYSTEM
5-15 P
3.6 Moving Up/Down the Pickup Roller
The pickup roller and the feeding roller are supported by a roller holder, and the pickup
roller is moved up and down in relation to the feeding roller. In standby state, the pickup
roller is at the uppermost position; during pickup operation, on the other hand, it moves
down to reach the paper surface. It operates as follows to pick up a single sheet of paper:
1) When the pickup solenoid (SL1) goes ON, the drive of the main motor (M1) causes the
cam 1 to rotate.
2) The rotation of the cam 1 causes the pickup lever to swing.
3) The swing of the lever causes the pickup roller to move down to come into contact with
the paper, and the pickup motor (M2) starts pickup operation.
4) The rotation of the cam 1 moves up the pickup roller shaft.
