Abstract
The requirements for optical character generation for a commercial electrophotographic high-speed printer—more than 10,000 1pm—are given. They lead to the conclusion that the principal elements of a character generator will he a laser, an acousto-optic deflector and a polygon mirror.
The arrangement of a character generator which has been realized in a commercial printer is described in detail. Its performance characteristics are calculated and compared to experimental results.
