A segment and heater fuser roll is disposed for a printing device including a plurality of heating elements in a preselected order relative to a voltage return. A plurality of voltage taps are disposed for applying selected power to ones of the plurality of heater elements. The heater elements vary in power density per unit length.

Apparatus and method for a multi-tap series resistance heating element in a belt fuser

An improved fuser includes a heater that enhances uniform heating by altering the localized resistance which alters the localized power output of a resistive trace at the point of contact with a conductor trace in order to provide extra heating and thereby compensate for heat loss at the resistive trace/conductor trace junction.

Multi-tap series ceramic heater cold spot compensation

A printing machine adapted to print an image on a plurality of different predefined sized sheets, including: means for selecting a sheet of a predefined size to be imaged; means for recording image; means for developing the image; means for transferring the image on the sheet; and a fuser for fusing the image onto the sheet, the fuser includes an endless belt having a plurality of predefined sized fusing areas being selectively activatable, and wherein the plurality of predefined sized fusing areas are arranged in a substantially parallel manner along a process direction of the belt; and means for activating one or more of the plurality of predefined sized fusing areas to correspond to one of the selected predefined sized sheet.
