Abstract
According to various illustrative embodiments, an apparatus, method, and system for variable rate fuser release fluid application are described. In one aspect, the apparatus comprises a supply of release agent material. The apparatus also comprises a release agent metering roller supported for contact with the supply of the release agent material. The apparatus also comprises a variable speed drive arranged to effect movement of the release agent metering roller in an endless path at different surface velocities. The apparatus also comprises a donor roller supported in contact with the release agent metering roller and a fuser roller of a contact fuser, the donor roller arranged to convey release agent material from the release agent metering roller to the fuser roller at various rates depending on a surface velocity of the release agent metering roller, wherein the variable speed drive is operative independently of the fuser roller.
