Original stopper
On this machine’s original paper feed system, the
leading edge of the original is separated by the air knife
and the paper is fed by the belts with air suction.
The original guides move the original to the center, and
the original stopper brings the leading edge of the
original to the correct position.
A handle is provided on the original stopper. If the
handle is pushed in, a click is released from the notch of
the side plate and the pinion gear turns along the rack.
When the original stopper is set according to the size
decal of the side plate, the leading edge of the original is
positioned on the recycle arm sensor and the original set
