ABSTRACT:
In an electrostatographic reproduction apparatus utilizing a dielectric member web supported by guide rollers for movement along a travel path in relation to electrostatographic process stations, including a web cleaning station, a web cleaning assembly is mounted so that it operates effectively to remove residual marking particles from the web without adversely effecting web tracking as it moves along its desired travel path. In a preferred embodiment of this invention, the cleaning assembly comprises a housing including a chamber adapted to store removed residual marking particles, and a member engaging the web to break the bonds between the residual marking particles and the web for sweeping such particles from the web into the chamber. The housing is mounted relative to one of the guide rollers for movement therewith as such guide roller guides the web along the desired travel path, and with the sweeping member in operative association with the web.
