Summary:Liquid supply systems, fusers and methods of supplying liquids in printing apparatuses are disclosed. An exemplary embodiment of a liquid supply system for supplying liquid to a fusing surface of a fuser member, comprises 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; and a liquid reducing roll having a third outer surface adapted to be disposed adjacent the second outer surface to define a second nip between the second and third outer surfaces. The metering roll is adapted to convey the liquid from the first outer surface to the second outer surface. The donor roll is adapted to be 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. The liquid reducing roll is adapted to remove a portion of the liquid from the second outer surface before the liquid is conveyed to the fusing surface.
