Disclosed is a xerographic printing apparatus and print cartridge including a deformable electrically conductive ring. According to an exemplary embodiment, a xerographic image rendering print cartridge includes a drive shaft, a photoreceptor drum and a deformable electrically conductive ring operatively associated with electrically connecting an inside surface of the photoreceptor drum to the drive shaft to provide a grounding electrical path.

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.

A fusing apparatus for xerographic printing includes two lamps therein. There is applied to the first lamp a first wave set and to the second lamp a second wave set, each wave set comprising a predetermined arrangement of active half-cycles for each time period. The first wave set and second wave set are related to substantially minimize simultaneous active half-cycles in each time period.
