IMAGE TRANSFER AND PAPER SEPARATION

Image Transfer
The Image Transfer Corona applies a DC negative corona emission to the underside of
the paper thereby attracting the positively charged toner onto the surface of the paper
to form a visible, developed image of the original. The Corona Unit is provided with a
Corona Wire cleaning mechanism: the operator has only to pull out the Lever on which
the Cleaner is mounted from the front of the copier, which cleans the Wire.
Paper Separation
The Paper Separator Corona showers the underside of the paper with both positive and
negative charges so that the paper can be easily separated from the PC Drum. In
addition, two Paper Separator Fingers physically peel the paper off the surface of the
PC Drum. (For details, see PAPER SEPARATOR FINGERS.)
The Image Transfer/Paper Separator Coronas Unit is provided with a Pre-Image
Transfer Guide Plate that determines the angle at which the paper comes into contact
with the PC Drum and keeps an optimum distance between the paper and the PC Drum
so that the image may be properly transferred onto the paper.
The Image Transfer/Paper Separator Coronas Unit is grounded via a high capacity resis-
tor, which improves its efficiency to discharge to the PC Drum side, thus reducing the
output current from High Voltage Unit HV1.
