Belt fuser having a multi-tap heating element
First Claim
1. A printing machine adapted to print an image on a plurality of different predefined sized sheets, comprising:
- means for selecting a sheet of a predefined size to be imaged;
means for recording image;
means for developing the image;
means for transferring the image on said sheet; and
a fuser for fusing the image onto said sheet, said fuser includes an endless belt having at least one heating element with a plurality of predefined sized fusing areas being selectively operatable, and wherein said plurality of predefined sized fusing areas are arranged in a substantially parallel manner along a process direction of said belt; and
means for activating one or more of said plurality of predefined sized fusing areas to correspond to one of said selected predefined sized sheet.
