Abstract
In one non-limiting embodiment an apparatus for controlling a fuser in an imaging apparatus includes a first fuser roller and a second fuser roller in parallel, adjacent orientation and configured to receive sheet media therebetween. The apparatus further includes an electrical voltage source applied across the fuser rollers. The apparatus also includes a voltage difference measuring device configured to measure a difference in the electrical voltage across the first and second fuser rollers when sheet media is received between the first and second fuser rollers, and to generate a voltage difference signal in response thereto. The device includes a controller which is configured to receive the voltage difference signal and to generate a fuser parameter control signal in response thereto. The apparatus also includes a fuser control device responsive to the fuser parameter control signal.
