Abstract: Pressure rolls for apparatuses useful in printing, apparatuses useful in printing and methods of making pressure rolls are provided. An exemplary embodiment of a pressure roll for an apparatus useful in printing includes a first layer including silicone rubber, the first layer including a first outer surface, a first end face and an opposite second end face; a second layer including a polymer overlying the first layer, the second layer including a second outer surface, a third end face and an opposite fourth end face; and a sealing material bonded to and covering the first, second, third and fourth end faces. The sealing material includes a polymer that is impervious to, and chemically resistant to, a release agent comprising silicone oil.

Abstract: Apparatuses useful in printing, printing apparatuses and methods of fixing marking material on media are provided.

Abstract: Liquid delivery systems, fuser assemblies, printing apparatuses and methods of delivering release agents to fusing imaging surfaces are disclosed. An embodiment of the liquid supply systems for delivering a liquid to a fusing imaging surface of a fusing member includes a first roll having a first outer surface adapted to contact a liquid contained in a sump; a first shim adapted to contact the first outer surface and the liquid in the sump; a second roll having a second outer surface adapted to contact the liquid in the sump, the first and second rolls contacting each other at an interface; and a second shim adapted to contact the second outer surface and the liquid in the sump. At least one of the first outer surface and the second outer surface is comprised of a compressible material which is compressed along the interface.
