At the turn in the transfer belt, the transfer belt drive roller [C] discharges the belt to reduce paper attraction,
and the paper separates from the belt as a result of its own stiffness.
The tapered parts [D] at both ends of the roller [E] help keep the transfer belt [F] in the center, so that it
does not run off the rollers.
Transfer Belt Cleaning
Toner collects on the transfer belt in the following cases. This toner causes streaking on the reverse sides of
prints as a result of a paper jam.
The cleaning roller [A] has a positive charge, so it can collect negatively charged toner and paper dust
from the transfer belt [B]. The cleaning roller always contacts the transfer belt.
The cleaning blade [C] scrapes toner off the cleaning roller.
