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.
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.
●
There is a mechanism provided that automatically cleans the corona wires at a
given timing, thereby preventing uneven charging caused by a dirty wire.
