White LED Scanner Development

Fuji Xerox's ApeosPort-IV series and DocuCentre IV series launched in 2009 offer multifunction devices intended to provide both energy-saving performance and convenience. Fuji Xerox Advanced Technology (FXAT) introduced a new technology for these devices using white LEDs as the color scanner's light source for the first time. Although the white LED provides high energy-saving performance, it lacked sufficient characteristics and properties. In order to introduce white LEDs to scanners, FXAT had to overcome two significant issues: uneven brightness and color variations. We thus developed our unique color correction image processing technology and optical components that disperse light evenly. As a result, we achieved 1.5 times the brightness using only about one-third the power of a conventional light source, and succeeded in commercializing a high-speed, full-color scanner (70 pages per minute / A4SEF) and achieving better energy-saving performance.
