Patent ID: 7277654

Claim:
A power supply control system for a fuser assembly in an electrophotographic device comprising: a power supply that accommodates different input voltages having: a power supply input configured to receive one of a first voltage or a second voltage; a first circuit branch coupled to said power supply input that is designated for a first type fuser assembly, said first type fuser assembly corresponding to said first voltage; a second circuit branch coupled to said power supply input that is designated for a second type fuser assembly, said second type fuser assembly corresponding to said second voltage; and a third circuit branch coupled to said power supply input that is common to said first circuit branch and said second circuit branch; said power supply being coupled to a select one of said first type fuser assembly or said second type fuser assembly, wherein: said power supply control system is configured such that installation of said first type fuser assembly to said power supply causes the formation of a circuit from said power supply input, through said first circuit branch of said power supply, through said first type fuser assembly, back to said power supply, though said third circuit branch of said power supply to said power supply input, and said power supply control system is configured such that installation of said second type fuser assembly to said power supply causes the formation of a circuit from said power supply input, through said second circuit branch of said power supply, through said second type fuser assembly and back to said power supply, through said third circuit branch of said power supply to said power supply input.
