PAPER SEPARATOR FINGERS
After image transfer, an AC corona emission is applied to the underside of
the paper by the Paper Separator Corona to neutralize the paper so that it
can be easily separated from the PC Drum. To further ensure that the paper
is positively separated from the PC Drum, there are two Paper Separator
Fingers attached to the Imaging Unit. They physically peel the paper off the
surface of the PC Drum.
To prevent the Paper Separator Fingers from damaging the surface of the
PC Drum, they are kept in the retracted position whenever they are not at
work. As illustrated below, the Fingers are brought into contact with, and
retracted from, the surface of the PC Drum by the Lever which is operated
by Separator Solenoid SL1.

The Paper Separator Fingers are also moved over a given distance to the
front and rear so that they will contact wider areas of the surface of the PC
Drum, thus preventing localized damage of the PC Drum surface.
This lateral movement is done by the Lever connected to the Cleaning Blade
and, when the Cleaning Blade is moved, the Separator Fingers are also
moved back and forth.
