Abstract

A fusing apparatus includes a fuser roll and a pressure roll which define a nip therebetween. An internal heat source is disposed within a interior of the fuser roll. An external heat source is disposed adjacent the fuser roll for heating an outer surface of the fuser roll. One or both of the internal heat source and the external heat source is controlled during a print job such that the thermal gradient across the fuser roll is adjusted. As a result, a temperature overshoot which generally occurs after the print job is finished can be reduced. The influence of subsequent jobs on the fuser roll surface temperature can also be accommodated.
