A drum maintenance system for use in an imaging device includes a sump having a bottom surface and a plurality of sidewalls which are arranged to accommodate a volume of release agent. A roller applicator is rotatably supported a first distance above the sump and partially submerged in the release agent in the sump. A foam layer is positioned on the bottom surface of the sump beneath the roller applicator that has a first thickness that is greater than the first distance such that the foam layer is compressed between the roller applicator and the bottom surface of the sump. A filter is sandwiched between the foam layer and the roller applicator. The compressed foam layer provides a compliance force that presses the filter against the roller applicator. The filter is configured to permit rotation of the roller applicator positioned on top of the foam layer while being pressed against the roller applicator by the foam layer.
