6. Transfer
Transfer is the process of transferring the toner image (visible image) formed on the drum surface
onto paper.
Method: A paper passing the side of the drum is
charged to the opposite polarity to the that of
toner by the corona discharge of the transfer
charger.
The toner moves from the drum surface onto
the paper.
- For smooth transfer
In the transfer bias processing of this equipment, bias voltage (+565 VDC) is applied to the
registration roller and transfer unit transport guide to prevent the charge produced by the transfer
charger from flowing into the transfer unit transport guide through the paper.
Output is controlled as follows to realizes the desirable transfability.
