A. Cleaning operation
1. The Cleaning Blade is pressed against the surface of the Photo Conductor to remove
toner left off the surface (trailing system).
2. The toner, which has been scraped off by the Cleaning Blade, is conveyed by the Toner
Collecting Screw and collected in the Waste Toner Storage Tank.
3. The toner is then stored as waste toner in the Waste Toner Storage Tank.
The waste toner is collected together with the Toner Cartridge when the Toner Car-
tridge is replaced with a new one. The Waste Toner Storage Tank is not detachable
from the cartridge.
