Abstract

In a toner cleaning housing 1 of a copier, a variable restriction air flow baffle is provided (here consisting of three generally V-shapedgrates 2). The air flow and toner from the cleaning brush 3 passes through the spaces between the grates 2, then through an exhaust port 4 into the vacuum sump and filter bag for this cleaning system (not shown). As shown in Figure 2, the spacing between the plural grates 2 is wider at the side of the cleaning housing 1 opposite from the exhaust port 4 side, so as to improve the equalization of the air flow from the cleaning brush 3 along its axis. The grates 2 may be inexpensively formed from sheet metal stampings, The upper surfaces of the grates 2 are all planar and downwardly

CLEANER WITH UNIFORM AIR FLOW (Cont'd)

In a toner cleaning housing 1 of a copier, a variable restriction air flow baffle is

provided (here consisting of three generally V~shapedgrates 2). The air flow and toner from the cleaning brush 3 passes through the spaces between the grates 2, then through an exhaust port 4 into the vacuum sump and filter bag for this cleaning system (not shown). As shown in Figure 2, the spacing between the plural grates 2 is wider at the side of the cleaning housing 1 opposite from the exhaust port 4 side, so as to improve the equalization of the air flow from the cleaning brush 3 along its axis. The grates 2 may be inexpensively formed from sheet metal stampings, The upper surfaces of the grates 2 are all planar and downwardly

sloping to avoid toner accumulation.
