BRUSH CLEANER CONTOURED AIR FLOW BAFFLES (Cont~d)

A variable restriction baffle in a toner cleaning housing 1 of a copier provides a uniform air flow along the axis of the cleaning brush 2. A smoothly contoured throat 3 is provided by this baffle to minimize airflow loses due to effects of turbulance. The smooth contour also eliminates abrupt surfaces of toner to accumulate on. The throat 3 cross~section is closed gradually, as viewed downwardly from the cleaning brush 2, to increase air velocity, thus accelerating toner particles through the minimum opening. The throat cross~section is thereafter gradually opened to normalize system pressure, i.e., it is increased on the exhaust port 4 side of the throat 3.
