2. Separating Paper
Figure 7-505
The figure shows the state immediately
after transfer to paper, and both the
separation solenoid (SL4) and the
separation push-up solenoid (SL3) are off.
The separation claw solenoid (SL4) and the
separation push-up solenoid (SL3) turn on.
This way, the separation claw roll is brought
into contact with the transfer drum sheet.
The separation claw is away from the
transfer drum sheet over a distance equal to
the thickness of the separation claw roll.
The separation push-up roll pushes up the
transfer drum sheet from inside by the work
of SL3, changing the shape of a portion of
the transfer drum sheet and, thereby,
increasing the curvature.
Thereafter, the body of the paper causes its
leading edge to separate from the transfer
drum sheet, and the separation claw slides
into the gap to start separation.
At this time, the butting lever of the
separation claw comes into contact with the
front side plate of the transfer drum unit so
as to maintain the height of the separation
claw.
