Abstract:
1. A universal fuser heating apparatus capable of receiving an input AC line voltage generated by a power source, said AC line voltage falling within a first low AC line voltage range, a second low AC line voltage range or a high AC line voltage range, said universal fuser heating apparatus comprising: a first resistive trace for receiving an AC line voltage falling within one of said first and second low AC line voltage ranges; a second resistive trace for receiving an AC line voltage falling within the high voltage range, one of said first and second resistive traces being formed over a substrate while the other of said first and second resistive traces is formed so as to at least partially overlap said one resistive trace; and structure for coupling at least one of said first and second traces to the power source in dependence upon whether the AC line voltage generated by the power source falls within said first low AC line voltage range, said second low AC line voltage range or said high voltage range.
