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.

An electrophotographic printing machine in which successive electrostatic latent images are recorded on a moving photoconductive belt. Each latent image is adapted to be recorded in a designated region on the photoconductive belt. The designated regions are separated from one another by an inter-image zone. A test patch is recorded in the inter-image zone. The number of designated regions on the photoconductive belt is adjusted so that the size of the inter-image zone is increased enabling a portion of the latent image to be recorded in the inter-image zone without overlapping any portion of the test patch.

A multi-function, multi-segment ac plasma erase lamp is provided to selectively erase previously charged areas of a photoconductive member. The lamp performs the conventional erase function of fixed edge erase, edge shift and patch generation, while adding the functions of variable edge erase along an edge to accommodate reduction images and changes in page size. Another feature of this erase lamp is a "dark" segment which is energized but is not light emitting. Its function is to enhance the turn on time for the light emitting segments. A still further improvement is the application of a voltage to a photoresist coating applied the the lamp surface to create a field which will repel toner and dust particles from that surface of the lamp.
