According to various illustrative embodiments, an apparatus for redistributing release agent on a fuser surface of an image forming device is provided. The apparatus has a fuser surface for contacting a sheet of media having an image formed thereon by the image forming device, the fuser surface moving in a traveling direction; and a smoothing roll for redistributing the release agent on the fuser surface from a first post-fusing distribution to a second distribution, the smoothing roll contacting the release agent on the fuser surface at a contact area and pressing the release agent against the fuser surface to redistribute the release agent from the first post-fusing distribution to the second distribution. The smoothing roll is adapted to redistribute the release agent such that the second distribution is more uniform across the fuser surface than the first post-fusing distribution.

Apparatuses useful for printing and methods of controlling a temperature of a surface in an apparatus useful for printing are disclosed. An exemplary embodiment of the apparatuses includes a first roll including a first outer surface and at least one first heating element for heating the first outer surface; a second roll including a second outer surface; a nip between the first outer surface and the second outer surface; a first temperature sensor for sensing a pre-nip temperature at a pre-nip location; and a first voltage modulator connected to each first heating element and the first temperature sensor. The first voltage modulator receives a temperature signal from the first temperature sensor indicative of the pre-nip temperature and modulates an AC voltage supplied to each first heating element to maintain each first heating element continuously ON at a power level ranging from partial power to full power to control the pre-nip temperature.
