Low force drum maintenance filter

A drum maintenance system for use in an imaging device wherein marking material is transferred from an imaging drum to a print sheet, the system comprising:

• a sump including a bottom surface and a plurality of sidewalls which are arranged to accommodate a volume of release agent for application to the imaging drum;
• an applicator rotatably supported above the bottom surface of the sump;
• a non metallic porous compressible layer connected to the bottom surface of the sump and compressed between the applicator and the bottom surface of the sump such that the vertical compressive force does not impede nominal rotation movement of the applicator during a drum maintenance operation;
• a shield extending from the bottom surface toward a top of the sump between and spaced apart from the applicator, the non metallic porous compressible layer, and a sidewall of the sump, the shield being spaced from the sidewall a distance to define a cavity between the sidewall and the shield, the shield including at least one opening that fluidly connects the cavity to the sump.

• and
• a shield spaced apart from the applicator and the non metallic porous compressible layer, the shield being positioned between the applicator and one of the side walls of the housing, the shield being spaced from at least one of the sidewalls to define a portion of a reclaimed release agent flow path therebetween, the reclaimed release agent flow path being configured to receive release agent diverted from the imaging drum, and the shield includes an electrically conductive grounding element for connection to ground potential.
