Transfer Belt Cleaning Mechanism
The cleaning blade [A], always in contact with the transfer belt, scrapes off toner and paper dust remaining
on the transfer belt.
Scraped off toner and paper dust falls into the toner collection tank [B] in the transfer belt unit. This toner
is not recycled. When the toner overflow sensor [C] detects toner overflow, the toner overflow indicator
lights. Up to 999 copies can be made before the toner overflow condition shuts down the machine.
