Patent ID: 7356271

Claim:
A developer fuser comprising: a first heating element for transferring energy for fusing a developer to a media during a copy process a second heating element a controller for controlling a first electrical power provided to the first heating element and a second electrical power provided to the second heating element, wherein the controller is adapted to set the first electrical power to a predetermined first ready power level before initiation of the copy process set the first electrical power to a first set-up power level upon initiation of the copy process, the first set-up power level determined, at least in part, by a physical characteristic of the media vary the first electrical power in response to an input from a first temperature sensor to maintain a fixing temperature during the copy process, the fixing temperature determined, at least in part, by the physical characteristic of the media set the first electrical power to the predetermined first ready power level upon completion of the copy process set the second electrical power to a predetermined second ready power level prior to initiation of the copy process set the second electrical power to a second set-up power level upon initiation of the copy process, the second set-up power level determined, at least in part, by a physical characteristic of the media vary the second electrical power in response to an input from a second temperature sensor to maintain the fixing temperature during the copy process set the second electrical power to the second ready power level upon completion of the copy process.
