Abstract

Apparatus is disclosed for locating an imaging lens array formed of a plurality of gradient index optical fibers on a print head having a linear array of light sources, such that the light sources are readily spaced from a photosensitive surface a distance equal to the total conjugate of the imaging lens array and the optical fibers are accurately spaced from the light sources in a direction along their optical axes so as to be midway between the light sources and the photosensitive surface.
