Abstract
A heat and pressure fusing assembly including an ink contamination-free release agent management (RAM) system is provided for supplying and applying release agent material onto an outer surface of a heated fuser roller suitable for fusing toner filled-in areas of a preprinted form. The ink contamination-free RAM system includes a housing defining a sump containing release agent material, a donor roller mounted partially within the sump for contacting, and applying release agent material onto, a surface of a heated fuser roller, and a metering roller mounted within the sump for moving and transferring a layer of release agent material from the sump onto the donor roller. The metering roller has a low energy surface layer made of PerFluoroAlkoxy (PFA) for preventing ink contaminants reaching the donor roller from transferring onto the metering roller, thereby preventing poor application of release agent onto the metering roller, and image defects resulting from such poor application.
