Patent ID: 7778580

Claim:
A liquid delivery system for delivering a liquid to a fusing imaging surface of a fusing member, comprising: 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; wherein at least one of the first outer surface and second outer surface is comprised of a compressible material which is compressed along the interface; wherein the first and second shims define a liquid passage through which the liquid is metered from the sump to the interface, and the first and second rolls are rotatable to meter the liquid through the interface to the fusing imaging surface of the fusing member.
