A layered structure, which may be used as a fuser member, comprises a first layer containing silicone; a second layer containing a fluoropolymer; and between the first and second layers, an adhesive layer comprising an aminosilane adhesive. In the layered structure, the second layer may additionally contain at least one of a polyamide-imide or a polyamide. Alternatively, or in addition, the adhesive layer may additionally contain fluoropolymer and at least one of a polyamide-imide or a polyamide.

There is disclosed a method for reusing a fuser member containing an outer layer having an original fusing surface that is deficient including: removing a portion of the thickness of the outer layer including the original fusing surface to create on the remaining outer layer a new fusing surface.
摘要:
A process for producing a fuser member coating including a) adding and reacting a fluoroelastomer, a crosslinking agent, a polar solvent, and a fluorinated copolymer surfactant to form a coating solution, and b) providing the coating solution on the fuser member to form a fuser member coating, wherein the fluorinated copolymer surfactant includes a copolymer selected from the group consisting of a fluorinated acrylate copolymer and a fluorinated polyether copolymer.
摘要:
A replaceable unit monitor assembly includes a substrate member, multiple thermal insulating stand-off members, and a monitor device mounted on the substrate member. The stand-off members mount the substrate member to an end hub of a fuser roll of a printing machine while limiting conductive heat transfer to the monitor device.
