Pick-Up From The Cassette Feeding Module-A2; Pick-Up Operation - Canon NP6218 Service Manual

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.
