Pick-Up
from Multifeeder
The
multifeeder
pick-up
roller
is
controlled by the main motor (Ml).
When
the multifeeder
paper
sensor
(al)
identifies
copy paper and the COPY
START
key is pressed,
the multifeeder
clutch (CL2) goes ON and the pick-up roller
starts to rotate to pick up the paper.
When
the copy
paper
reaches
the
registration
roller,
the multifeeder
clutch
(CL2)
goes
OFF
and the pick-up
roller
stops.
At the same
time,
the multifeeder
solenoid
(SL3)
goes
ON to transmit
the
drive
of the main motor
(Ml)
to the cam
mechanism,
thereby
lowering
the multi-
feeder
holding
tray to prevent
dirt on the
next copy paper in duplex.
The multifeeder
solenoid
(SL3) goes
OFF as soon as the first copy paper moves
past the pre-registration
paper moves
past
the preregistration
paper
sensor
(Q2); at
the time, the multifeeder
holding tray returns
to the normal pick-up position.
