Color-Fusing Technology Using Induction Heating
  DOI :  10.2352/ISSN.2169-4451.2003.19.1.art00017_1  Published OnlineJanuary 2003

A unique color-fusing technology using induction heating has been developed, which has adopted in a newly released one-pass color laser printer. The color-fusing unit consists of a thin fusing belt made of heat-resistant resin containing metal, a heating roller with low thermal capacity, a fusing roller, and a pressure roller to compress the fusing roller with the fusing belt in between. An induction heater is disposed along and adjacent to the outer periphery of the fusing belt and heating roller. The newly developed fusing belt has a low thermal capacity, with a thickness of only several hundred micrometers, and has a structure that selfheats at high efficiency since eddy currents are generated in the heating portion by electromagnetic induction. The alternating magnetic field generated by the induction heater efficiently heats both the fusing belt and heating roller. This design shortens the warm-up time of the fusing unit from cold start to only 20 seconds. This color laser printer eliminates the need to preheat the fusing unit during stand-by time by employing the induction heating technique and achieves energy saving of 90% or more compared with conventional printers.
