ABSTRACT:
Release material applicator structure for utilization in a heat and pressure fuser including a fuser roll structure for fixing toner images to support sheets. The release material employed is solid at room temperature and liquid at the operating temperature of the heated fuser roll structure. It is disposed in a sump and contacts the fuser roll structure. A collector bar is supported by the sump such that it is disposed adjacent to the fuser roll structure and coextensive therewith. When the liquefied release material reverts back to its solid form it accumulates on the collector bar and the bar maintains contact of the release material with the fuser roll structure.
