Technologies of Low Energy Consumption Fuser

Abstract

In electrophotographic machines, a fuser portion consumes almost all electric power. And the power consumption at standby state is larger than that of operation state. Therefore fusers that can be heated-up rapidly have been developed to reduce electric power. Strong heaters and fusers with low heat capacity are required for quick warm-up fuser systems. On the other hands, in the low heat capacity fuser systems, excess temperature rise at the both ends portion of the fuser roller inevitably occurs when smaller sized paper is continuously printed. This phenomenon reduces printing productivities. This paper introduces recently announced energy-saving type fusers.
