2.7.5 TRANSFER BELT CLEANING MECHANISM

Some toner may adhere to the transfer belt when paper jams occur, or when the
by-pass feed table side fences are set in the wrong position. The adhered toner
must be removed to prevent the rear side of the copy paper from getting dirty.
The cleaning roller [A] is always in contact with the transfer belt. It collects toner
and paper dust adhering to the surface of the transfer belt. This is because a
positive bias is applied to the cleaning roller and this attracts the negatively
charged toner on the transfer belt.
A counter blade system cleans the cleaning roller. The cleaning blade [B] scrapes
off toner collecting on the cleaning roller [A]. The gear [C] moves the agitator plate
[D] from side to side to transport toner to the toner collection coil [E]. Toner cleaned
off the transfer belt is transported to the waste toner collection bottle by the coil.
