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 2.6MΩ resistor, which
improves its efficiency to discharge to the PC Drum side, thus reducing the output current
from the High Voltage Unit.
