5.6 TRANSFER BELT CLEANING MECHANISM

[C]
Some toner may adhere to transfer belt when paper jams occur, or when the
by-pass feed table side fences are set in the wrong position causing the
erase lamp to miss some toner. The adhered toner must be removed to
prevent the rear side of the copy paper from being stained.
The cleaning blade [A] scrapes off any toner remaining on the transfer belt.
A counter blade system is used for the transfer belt cleaning. The surface of
the transfer belt is coated to make it smooth and so prevent the cleaning
blade from being flipped by the transfer belt.
The lever [B] on the front end of the cleaning blade releases the cleaning
blade when the transfer belt unit is lowered and the lever is pushed by the
transfer belt unit support prop. (The transfer belt unit is lowered when the
lever [C] is turned anti-clockwise)
When the cleaning blade is released, the edge of the cleaning blade rubs the
seal so that the seal [D] removes the toner or paper dust on the cleaning
blade edge.
