Abstract

A printer system includes (a) an f-.theta. lens producing lateral color aberration; (b) three laser light sources, each producing a light beam for use with said f-.theta. lens; and (c) modulators modulating these laser light beams at different data rates from one another. The ratio of the different data rates is being used to compensate for the lateral color aberration produced by the f-.theta. lens.
