ABSTRACT:
A heater controller system for a fusing apparatus configured for fusing marking material to a substrate in a printing system includes a power source for supplying power to a heating element having at least two sections. The controller system further includes at least one switch configured to selectively control at least two bidirectional switches for selectively providing current supplied by the power source to at least one of the at least two sections during operation of said heater controller system in one of at least two modes of operation, each of the at least two modes of operation corresponds to a particular size of said substrate.
