Thermal conservation assembly for roller fuser

Abstract

in an electrophotographic copier including a fuser having a heated fuser roller, a thermal conservation assembly for minimizing thermal losses and facilitating roller maintenance and removal. The assembly includes first and second heat reflective members which are mounted for pivotal movement between a first position wherein the members are in close proximity with the fuser roller in order to minimize thermal losses and a second position wherein said members are out of proximity with said roller in order to facilitate access to the roller for maintenance and removal. In roller fusers having a pair of heated fuser rollers such as for duplex copy fusing, each roller is provided with a movable thermal conservation assembly.
