Energy saving fixation scheme that allows high speed fixation of toner

Different from traditional method of fixing toner on paper by adding pressure from rolls on and under the paper, this scheme increases heat conduction efficiency considerably and shortens fixation time, by changing the lower roll to a belt and widening contact area of the roll. This greatly curtails warm-up time from standby point (Sleep Mode), thus realizing energy saving and miniaturization.of the fuser unit In addition to that, by optimizing temperature distribution, further speed-up and energy saving is realized at the same time.

 “High-Speed Free Belt Nip Fusing (High-Speed FBNF) Technology” keeps evolving

The free belt nip fusing technology, which gained excellent reputation for realizing compactness and energy conservation, is applied in many Fuji Xerox products and is continuing to evolve. In recent years, high-speed printing has been realized due to improvement in the life span and reliability of products, and better energy-saving technologies. From a technical point of view, a highly efficient heat lamp has been applied to improve heat efficiency. In addition, heat distribution has been evened during warm-up, stand-by, and paper-feed modes by setting the lamp at an optimum location, resulting in lower power consumption. Furthermore, a material with a low friction coefficient was newly developed and used as the sliding material in the fusing belt to stretch the life span of the part and reduce power consumed by the drive motor. ApeosPort C7550 I (50 color copies per minute - A4 long-edge feed), a multifunctional color device that applies the high-speed free belt nip fusing technology, requires only one-fourth the warm-up time that is required by DocuCentre C500 (12.5 color copies per minute - A4 long-edge feed, a device that uses the traditional fusing technology. This high-speed free belt nip fusing technology realized both speed and energy conservation and became the main factor in winning the 16th Energy Conservation Awards held by the Energy Conservation Center (in Japan) (total of 12 models - ApeosPort C7550 I and 5 other types).
