Transfer belt cleaning process

The residual toner on the surface of the transfer belt is removed after the paper transfer process. See
"Printer theory of operation" on page 1-14 for transfer belt cleaner unit location.
The belt cleaner brush is a semiconductor-type fur brush. The cleaning roller is charged by voltage FCBV.
The resistance of the cleaning brush against the cleaning roller charges the brush. The brush in turn
contacts the surface of the rotating transfer belt. The negatively charged toner adheres to the positively
charged (FCBV) brush, which cleans the transfer belt. The cleaning brush does not contact the transfer belt
during the imaging process.
Waste toner, adhering to the surface of the cleaning roller, is removed by the cleaning blade, routed by the
waste toner feeder to the waste toner container where it is deposited.
