A cleaner assembly according to one embodiment includes a cleaner blade that extends upward in a cantilevered manner and that includes a cleaning edge for contacting a surface to remove toner from the surface. A waste toner sump is positioned adjacent to a rear side of the cleaner blade for storing toner removed from the surface by the cleaner blade. A film seal extends in a cantilevered manner toward the rear side of the cleaner blade and contacts the rear side of the cleaner blade along a longitudinal length of the cleaner blade. A foam seal is positioned between the rear side of the cleaner blade and the wall below the contact between the rear side of the cleaner blade and the film seal. The foam seal extends along the longitudinal length of the cleaner blade.
