Canon NP6012F - Controlling the Pick-Up Roller

B. Controlling the Pick-Up
Roller
1. Outline
The copier has two pick-up rollers;
namely, the cassette pick-up roller and the
multifeeder pick-up roller. The drive to the
rollers is switched by a gear u&that shifts
the drive path; for this reason, the drive is
transmitted to only one of the two rollers at a
time.
2. Controlling the Cassette Pick-Up
Roller
The cassette pick-up roller is controlled
by the spring clutch,‘control ring, and pick-up
solenoid (SLl).
When the solenoid turns on, the pawl
moves away from the control ring,’ thereby
allowing the drive of the main motor (Ml) to
be transmitted to the pick-up roller.
When the pick-up roller starts to rotate,
copy paper is picked up and sent as far as
the registration roller. The registration roller,
in turn, serves to control the copy paper so
that it matches the leading’ edge of the
image on the photosensitive drum.
