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 1-19 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.
