Abstract (en)
Method and apparatus for operating and regulating a heat soucre (103) in a reproduction machine, particularly for a fuser in a copier. The machine is operable in at least 3 modes, a warm-up, a stand-by, and a copy mode. The amount of energy supplied to the heat source (103) depends on the present mode of the machine and the actual temperature T of the fuser: The supplied power is at level P1 during the warm-up mode until T >/= T1 (T1 is a given temperature). Then, power is reduced to P2. In stand-by mode, power is increased to P2 + DELTA P1, if T < T2 (T2 is a given operating temperature), and decreased to P2 - DELTA P1, if T >/= T2. In the copy mode, power is increased to P2 + DELTA 2 if T </= T2 and increased to P2 + DELTA P3 if T DELTA T2.
