Abstract

Disclosed is a method and system for fiber contamination control in hybrid scavengeless developer (HSD) housings. Thus, in a HSD housing, a series of filter wires are situated in close proximity to an electroded donor or developer roll such that any debris, for example, paper fibers, hairs, dust, or related particulate material contacts the filtering wires and is electrostatically trapped on the filter wires thereby removing the potential for the debris from contaminating the electroded roll or HSD wires of the HSD system. The filtering wires can be electrically biased to optimize their filtering performance. The filter wires are preferably incorporated into, or integral with, a toner auger transport system which delivers toner particles from a reservoir to a magnetic brush roll and thereafter to a HSD developer roll. The filter wires are preferably spaced apart by an amount of about 30 degrees as viewed from the end of the auger.
