EXTERNALLY HEATED FUSING ROLLER

摘要

Reducing variation in the surface temperature of an externally heated fusing roller in an electrophotographic machine, the variation typically occurring during the beginning of a fusing run, by detecting the beginning of a fusing run and applying a modified fusing temperature set-point characteristic to the fusing roller. The mode of the electrophotographic machine is monitored to determine whether the machine has changed operating modes, and the application of the modified fusing temperature set-point characteristic (108) to the fusing roller is ceased when the electrophotographic machine changes modes. The force with which the heating rollers engage the fusing roller is controlled within desired operating limits (110).
