Latest High-speed Color Fusing Technologies

Abstract

In recent years, energy-saving technologies for electronic copiers have evolved with the revision of ENERGY STAR^® and Blue Angel Mark. However, in the area of 65 to 75cpm color high-speed machines for offices, as a result of the trade-off with maintaining the performance, the energy-saving technology cultivated with low and medium speed machines cannot be transplanted as it is, and technological innovation for improving the TEC (Typical Electricity Consumption) value is not progressing compared with low and medium speed machines. In e-STUDIO7516AC series which is a TOSHIBA TEC's high-speed machine for office use, an IH (Induction Heating) fuser meeting the specifications for high-speed machines was developed based on the IH fuser used in medium-speed machines, and the industry-leading top TEC value was achieved (as of October 2019). This article describes recent development trends in fusing technology, and IH fusing technology introduced in the e-STUDIO7516AC series.
