ABSTRACT:
An improved release agent delivery apparatus is disclosed for use in laser printers, plain paper copiers, facsimile machines, and similar printing apparatus. The delivery apparatus comprises an absorbent textile core filled with release agent, a permeable membrane surrounding the textile core to form a sheathed wick member, and a mounting sleeve adapted to attach the sheathed wick member in operative contact with the printer. The apparatus has numerous operational advantages over existing oil delivery apparatus, including providing multiple contact surfaces for longer operational life before replacement, ease in cleaning and regeneration, improved durability and reduced wear, and more compact and versatile operation.
