Abstract

In brush cleaning vacuum-backed systems for conventional xerographic copying machines, a flicker bar has been used to dislodge toner from the brush fibers. In a vacuumless system, it is necessary to use the flicker bar as an aerodynamic object 10 causing a flow restriction, and it must then be placed downstream of the exhaust vent 11. In this case, dislodged toner will be carried into the downstream side of the housing, reducing cleaning efficiency. The present proposal is to use a second flicker bar 12 in the form of a rod positioned upstream of the exhaust vent which assists in the release of toner particles from the brush housing prior to the exhaust vent.
