Abstract
An agglomerate spot cleaning blade is supported to cleaning housing, thereby forming a substantially enclosed chamber, in sealing engagement with respect to the photoreceptor surface. Contact is maintained between a cleaning brush, located within a cleaning housing, and a blade, whereby rotating brush fibers remove accumulated agglomerate debris particles from the blade. A substantially air-flow free environment is maintained for removal of residual toner and debris from the photoreceptor surface and the blade, without the need for a separate vacuum/air removal system assist, or a separate manual maintenance step.
Claims14
A printing machine of the type having a latent image recorded on a surface developed with toner, wherein the improvement comprises:
- a housing defining an open end, said housing being positioned with the open end adjacent to the surface;
- a brush, rotatably supported within said housing in contact with the surface, for removing toner and debris from the surface;
- and
- a blade adapted to remove toner and debris therefrom, said blade being supported on said housing adjacent the open end to form a substantially continuous surface with said housing in a sealing engagement with the surface to maintain a substantially air-flow free environment within said housing.
