2 July 1999 Development of four-beam laser scanning optical system
Author Affiliations +
A laser scanning optical system using four isolated semiconductor lasers has been newly developed for a high- speed, high-resolution digital copier and printer. This system can synchronously scan four beams, so that it can form an electrostatic latent image on a photoconductive drum four times faster than a single beam optical system.
