Outline; Sequence Of Pick-Up Operations - Canon NP6251 Service Manual

1. Outline

The copy paper inside the cassette is held up by a lifter so that it remains in contact
with the pick-up roller.
When the pick-up clutch (CL10/CL12) turns on, the pick-up roller starts to rotate to
feed copy paper. Thereafter, the pick-up roller releasing solenoid (SL11/SL12) turns on
and, as a result, the pick-up roller moves away from the surface of the paper.
The feeding roller and the separation roller serve to make sure that only one sheet
of copy paper is moved to the feeding path; then, the copy paper is forwarded to the
registration roller by the vertical path roller.
The registration roller serves to make sure that the leading edge of the copy paper
matches the leading edge of the image on the photosensitive drum.
