Apparatus and methods for fusing developer are disclosed. A developer fuser may include a first heating element for transferring energy for fusing developer to a media. The developer fuser may have a controller for controlling the power applied to the first heating element. Upon initiation of a copy process, the power applied to the first heating element may be set to a set-up power level determined, at least in part, by a physical characteristic of the media. The power applied to the first heating element may be further varied in response to a first temperature sensor to maintain a fixing temperature during the copy process. The fixing temperature may be determined, at least in part, by the physical characteristic of the media.
