CHAPTER 5 PICK-UP/FEEDING SYSTEM

III.PICK-UP FROM THE CASSETTE FEEDING MODULE-A2

A. Pick-Up Operation

When the pick-up clutch (CL1cu, CL2cu) turns on while the cassette unit motor (M1cu), the pick-up roller starts to rotate to pick up copy paper; the paper is then moved to the registration roller by the vertical path roller. (The sequence that follows is the same as when paper is picked up from the cassette in the copier.)

For pick-up operation from the cassette feeding unit, pick-up sensors (PS1cu, PS3cu) are used to check the arrival of paper, thereby deciding when to turn off the pick- up roller according to the size of paper.
