Pick-Up from
Multifeeder
The
multifeeder pick-up
roller
is
controlled
by
the
main motor
(M1
).
When
the multifeeder
paper sensor
(Q1)
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
(M1)
to
the
cam
mechanism,
thereby lowering the
multifeeder
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 sensor
(Q2);
at
the
time,
the multifeeder holding
tray returns to
the
normal
pick-up
position.
