Abstract

The essential elements of a roll fuser as shown in the figure are the fuser roll, the pressure roI1,the release agent management system, the heating lamp, and a control element. The main advantage of heatipressure roll systems is the efficient use of thermal energy. Furthermore, the soft roll fuser offers an additional advantage of high copy quality by using a soft surface on the fuser roll to conform to the contours of the toner piles on the copy instead of squashing them as in hard roll fusers. However, difficulty has been encountered in speeding up copiers that employ soft roll fusers.
