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.
