CHAPTER 7 PICK-UP/FEEDING SYSTEM
7-8
B. Multi-feeder pick-up mechanism
1. Lifter plate operation
The mechanism for raising the lifting plate is illustrated in the diagram below.
During standby, the lifter plate is supported and lowered by the cams fitted onto the
front and rear of the multi-feeder pick-up roller.
When the paper roller rotates, the cams are also made to rotate, causing the lifter
plate to rise, and the paper set in the multi-feeder comes into contact with multi-feeder
pick-up roller.
A separation pad and sub pad are fitted onto the pick-up roller’s facing surface, and
through the separation process, only one sheet of paper is fed at a time to the main unit.
