Abstract: An apparatus and method of manufacturing a fluorosilicone composite for a variable data lithography imaging member surface layer. Examples of the fluorosilicone composite include a first part and a second part, the first part having fluorosilicone, carbon black, silica and butyl acetate, the second part having a platinum catalyst, a crosslinker, butyl acetate and an inhibitor. The first part may also include a dispersant (e.g., a polyoxyalkylene amine derivative) that removes a need for shaking the dispersion by paint shaker and instead allows a more manufacture friendly roll ball milling process. The dispersant will also help in stabilizing the fluorosilicone composite for scaled up production.

Abstract: An apparatus comprises a frame having a first frame section connected to a second frame section. The frame also has at least one physical connection that allows the first frame section to move relative to the second frame section. A first roller is connected to the first frame section. The first roller has a crowned outer surface surrounding an axle. Also, first connectors connect the first roller to the first frame section. The first connectors allow the first roller to rotate around the axle and allow the first roller to move in a direction parallel to the axle. A second roller is also connected to the second frame section. At least one biasing member is connected to the first frame section and the second frame section. The biasing member applies a bias to cause the first frame section to move away from the second frame section. A belt substrate contacts the first roller and the second roller. A latch is connected to the first frame section and the second frame section.

Abstract: Fixing belts, fixing devices and methods of making fixing belts are provided. An exemplary embodiment of the fixing belts includes an inner layer comprising a first surface forming an inner surface of the fixing belt and a second surface opposite to the first surface, the inner layer comprising a first polymer; an intermediate layer overlying the second surface of the inner layer, the intermediate layer including a third surface, a first end face and a second end face opposite to the first end face, the intermediate layer comprising silicone rubber; and an outer layer including a fourth surface forming an outer surface of the fixing belt, the outer layer overlying the third surface, the first end face, the second end face and portions of the second surface disposed outward from the first end face and second end face, the outer layer comprising a second polymer. The outer layer seals and protects the intermediate layer from exposure to a liquid release agent applied to the fourth surface.

Abstract: This is a mandrel used to fabricate seamless belts including those used in electrophotographic marking systems. The mandrel has a center core unit with two circular caps on each side. In between the caps is sandwiched a deformable O-ring which is outwardly deformed upon tightening of the two caps together. Once a tubular sheet is placed over the mandrel, the elastomeric O-ring will hold the sheet in place for further processing.
