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 the Separator Solenoid.

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 to 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.
