IMAGE TRANSFER
5.2 IMAGE TRANSFER AND PAPER SEPARATION OVERVIEW
[E]
This model uses a unique transfer belt unit instead of the transfer and
separation corona unit. The transfer belt unit consists of the following parts:
[A] Transfer belt
A belt (length: 321 mm) with high electrical resistance which holds a high
negative electrical potential and attracts the toner on the OPC drum onto
the paper. Also the electrical potential attracts the paper itself and helps
paper separation from the OPC drum.
[B] Transfer bias roller
Applies transfer voltage to the transfer belt.
[C] Transfer belt lift lever (driven by a solenoid)
Lifts the transfer belt to contact the transfer belt with the OPC drum.
[D] Transfer power pack
Generates the constant transfer current.
[E] Transfer belt cleaning blade
Removes toner attached on the transfer belt to prevent the rear side of the
paper from being stained.
[F] Discharge plate
Discharges the remaining negative charge on the transfer belt and feeds it
back to the transfer power pack to control the transfer current and keep it
constant.
