2.9 IMAGE TRANSFER AND PAPER SEPARATION
2.9.1 OVERVIEW
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
positive electrical potential to attract toner from the drum to the paper.
Also, the electrical potential attracts the paper itself and helps the paper to
separate from the drum.
[B]: Transfer bias roller and transfer belt bias brush
Applies transfer voltage to the transfer belt.
[C]: Transfer belt lift lever (driven by a solenoid)
Lifts the transfer belt into contact with the drum.
[D]: Transfer power pack
Generates a constant transfer current.
[E]: Cleaning roller and cleaning roller cleaning blade
Removes toner remaining on the transfer belt to prevent the rear side of the
paper from getting dirty.
[F]: Transfer belt cleaning blade
Removes toner from the transfer belt. Any toner that is not removed by this
blade is removed by the cleaning roller [E].
