ABSTRACT:
Preventing the imaging forming process of an electrostatographic reproduction apparatus having a plurality of imaging modules in tandem relative to a receiver transport belt moveable along a transport path from becoming contaminated with fuser release oil. A substantially uniform layer of the pigmented marking particles from the development subsystem of the image forming process is deposited onto the photoconductive member of the image forming process during any non-imaging cycles of the process, including cycle down, non-imaging skip frames, or recovery from a receiver jam. The substantially uniform layer of pigmented marking particles acts as a barrier to block fuser release oil from the photoconductive member and as a vehicle to carry away contaminating fuser release oil.
