  • Patent number: 5241159
    Abstract: A fusing roller is provided that has multiple pattern groupings of heat elements of different heating capacities located adjacent heat sensors within the fusing roller. The individual heat elements of the same grouping are of the same heating capacity, while individual heat elements not of the same grouping are of different heating capacity. The difference in heating capacity is due to the differences in coil length of the various heat elements. By controlling the flow of current to any one or more groupings of heat elements, a specific fusing temperature range can be applied to designated areas about the peripheral surface of the fuser roller, thereby maintaining these areas of the fusing roller at a desired fusing temperature.
