Abstract:
1. 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; an adhesive connecting the non metallic porous compressible layer to the bottom surface of the sump; and a filter layer connected to the porous layer with another adhesive layer and the filter layer being sandwiched between the applicator and the porous layer.
