PAPER DELIVERY
6.8.3 PAPER SEPARATION FROM THE DRUM
Air knife
The air from the air knife fan
motors [A] separates the paper
from the drum.
The air knife fan motors start
blowing air when the print start
key is pressed or when master
cutting is finished. The paper
passes under the exit pawl and
is delivered to the delivery table.
Exit pawl air pump
Drive from the main motor is
transmitted to the pump gear [A].
When the gear [A] rotates, it
drives the piston [B] back and
forth.
The piston moves forward and
pushes a jet of air out through the
nozzle [C]. This jet of air helps to
separate the paper from the
drum.
