Waste Toner Collection
All the waste toner that is generated during the cleaning of the Drums and belts, 
as well as the depleted Developing Powder from the Developer Housing Assemblies 
are transported into the Waste Cartridge by the Auger.
Although only one Drum and Developer are shown in the illustration for 
simplification, each section has its own collector.
