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.

A process for producing a fuser member coating including a) adding and reacting a fluoroelastomer, a crosslinking agent, a polar solvent, and a fluorinated blend comprising a fluorinated copolymer surfactant and a fluorinated polydimethylsiloxane additive 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 comprises a copolymer selected from the group consisting of a fluorinated acrylate copolymer and a fluorinated polyether copolymer, and wherein said fluorinated polydimethylsiloxane additive comprises pendant fluorinated groups.
摘要:
Polyetherimide-b-polysiloxane block copolymers are useful as surface layers for fuser and fixing members in various printing devices, including electrostatographic imaging systems and ballistic aerosol marking devices. Optionally, the polyetherimide-b-polysiloxane block copolymers are fluorinated, or include at least 50% by weight siloxane.
摘要:
A donor member useful in ionographic or electrophotographic apparatuses and preferably useful in hybrid scavengeless development units, having a substrate and an oxidized transport coating including charge transport molecules, polymer binder, and an oxidized oligo arylamine salt comprising a cation of an oligo arylamine molecule and a counter anion.
摘要:
The present teachings disclose a coating that includes a inner layer having a first modulus and a first roughness; and a surface layer having a second modulus. The first modulus is greater than the second modulus. When the coating is subjected to a nip pressure the surface of the coating exhibits a surface roughness approximately equal to the first roughness.
