ABSTRACT:
Apparatus and method for minimizing heating effects and reducing power surges in the fuser element of a copier/duplicator by providing a reduce power, soft turn-on operation during single copy machine cycles followed by a full power turn-on at entry of the copy paper into the fusing station. An adaptive fusing circuit is disclosed so that each of multiple modes of machine operation are properly timed with the fuser soft power-on and full power turn-on features. Available machine modes of operation include chain feeding and large document copying using both a fixed and a movable optical scanning system.
