6.15.5 TRANSFER BELT CLEANING
Some toner may adhere to the transfer belt when paper jams occur. The adhered
toner must be removed to prevent the rear side of the copy paper from getting dirty.
The cleaning blade [A] scrapes off any toner remaining on the transfer belt. This is
a counter blade system.
Even if the toner is not completely removed due to paper dust stuck on the transfer
belt cleaning blade [A], the positively charged cleaning bias roller [B] attracts the
remaining toner. The bias roller cleaning blade [C] scrapes toner off the cleaning
bias roller.
The surface of the transfer belt is coated to make it smooth and prevent the
transfer belt from flipping the cleaning blade.
The toner collection coil [E] transports toner cleaned from the transfer belt to the
waste toner collection bottle. The agitator [D] moves the toner to the collection coil,
and prevents the toner in the cleaning unit from forming clumps.
