There is an endless demand for improved image quality and higher speed in printer applications. To meet market requirements, in 2003 we launched DocuColor 1256 GA, the world’s first VCSEL-based electrophotographic printer utilizing a 780 nm single-mode \(8{}\times{}4\) VCSEL array. The printer features 2,400 dots per inch (dpi ) resolution, which is still the highest level in the industry, and a speed of 12.5 pages per minute (ppm ). A two-dimensional VCSEL array makes it much easier to increase the pixel density and printing speed by simultaneously scanning the 32 beams on the photoconductor in the light exposure system . Adopting VCSELs as a light source also contributes to reduced power consumption, because the operating current of VCSELs is extremely small and the wall-plug efficiency is very high. In this chapter, we explain the key technologies of VCSELs in light exposure system of laser printer, as well as their required characteristics to assure high image quality.

The authors wish to acknowledge their colleagues who developed the \(8{}\times{}4\) VCSEL array, as well as the xerography engineers of FUJI XEROX, without whom it would not have been possible to realize the VCSEL-based printer product. The authors would like to specially thank Chikaho Ikeda, Hiroaki Tezuka, Jun-ichi Ichikawa, and Takaaki Sakakibara for the VCSEL-ROS development.
