Fuji Xerox LED Print Head Wins Technology Award

The Imaging Society of Japan Recognizes Its High-Quality and High-Resolution Images

TOKYO, June 11, 2009 - A high-resolution LED (light-emitting diode) print head developed by Fuji Xerox Co., Ltd. won The Imaging Society of Japan’s Technology Award yesterday. The LED print head with self-scanning light emitting device is incorporated into Fuji Xerox’s color multifunction devices and color printers.

The development of a 1,200 dpi self-scanning LED together with a dedicated ASIC (application-specific integrated circuit) has overcome the issues presented by conventional LED print heads and also has realized high resolution. The Imaging Society of Japan, in presenting the award, recognized the contribution of Fuji Xerox’s LED print head to the advancement of electrophotographic technology.

About the Award-Winning LED Print Head
LED print heads require neither a polygon mirror nor the motor to rotate the mirror, which enables a size reduction as well as noiseless operation. While they have such advantages, conventional LED print heads had difficulty in realizing higher image quality due to numerous light-emitting elements, which cause fluctuations in the amount of light resulting in unevenness in color density.

Fuji Xerox has responded to these issues by developing a 1,200 dpi, high-resolution self-scanning light-emitting device (SLED^*1) along with a technology, DELCIS^*2, which enables precise integrated control of all light-emitting elements by a single high-performance ASIC. Furthermore, Fuji Xerox adopted lenses with uniform optical characteristics to create a simple-structure, high-resolution LED print head (1,200 x 2,400 dpi) (Figure 1), which has realized downsizing as well as high-quality images equal or superior to those produced via laser raster output scanner (ROS) systems.

* 1 Self-Scanning Light Emitting Device: A device that can emit light in sequence from its elements.

*2 Digitally Enhanced Lighting Control Imaging System: An LED exposure control technology that uses proprietary SLEDs. Highly precise correction of the amount of light is achieved by ASIC’s integrated control of all SLEDs, resulting in a high resolution of 1,200 x 2,400 dpi. DELCIS is a registered trademark in Japan.

Products Incorporating the LED Print Head
Fuji Xerox incorporated this LED print head in four models of its full-color digital multifunction devices which was recently launched in Malaysia (ApeosPort-III C3300/C2200, DocuCentre-III C3300/C2200), and in key products such as the color printer DocuPrint C2250

Fuji Xerox’s LED print head has dramatically reduced its size and weight compared to the conventional laser ROS system allowing more room for a device’s paper ejection (equal to the space for one paper tray) where a finisher capable of stapling can be loaded (Figure 2).
