Patent ID: 7881649

Claim:
A liquid supply system for supplying liquid to a fusing surface of a fuser member, comprising: a metering roll having a first outer surface; a donor roll having a second outer surface disposed adjacent the first outer surface to define a first nip between the first and second outer surfaces; a liquid reducing roll having a third outer surface disposed adjacent the second outer surface to define a second nip between the second and third outer surfaces; and a blade that removes liquid from the third outer surface, wherein the blade has an efficiency, b, which is the ratio of an amount of liquid removed from the third outer surface by the blade to an amount of liquid incident to the blade, and b is selectively variable from about 0 to about 1, wherein: the metering roll conveys the liquid from the first outer surface to the second outer surface; the donor roll is disposed adjacent the fuser member such that the second outer surface and the fusing surface define a third nip, and to convey the liquid from the second outer surface to the fusing surface; and the liquid reducing roll removes a portion of the liquid from the second outer surface before the liquid is conveyed to the fusing surface.
