Abstract: A fuser heater member for an electrophotographic imaging device, including a heater member. According to an example embodiment, the heater member includes positive temperature coefficient (PTC) material disposed along a width of a fuser nip of the fuser assembly; first and second electrodes disposed along disposed surfaces of the PTC material; an intermediate layer disposed over the second electrode; and at least one resistive trace disposed along the intermediate layer along the width of the fuser nip. The heater member includes a plurality of wire segments coupled to the first and second electrodes and the resistive elements for use in generating heat from at least one of the PTC material and the at least one resistive trace during a fusing operation.

Abstract: A method and system for fusing toner to media sheets in an imaging device. The system includes a fuser heater having a first heating element and a second heating element, the fuser heater providing heat to a fuser nip; and heat control circuitry coupled to the fuser heater for passing current through the first and second heating elements of the fuser heater to generate heat therefrom. The system further includes a controller coupled to the heat control circuitry, the controller controlling the heat control circuitry for passing current through the first heating element during a warm up operation and passing current through the second heating element during a fusing operation following the warm up operation, the fusing operation fusing toner to a sheet of media.
