An electro-optic imager, used for exposing photosensitive media imagewise, wherein a linear array of scanning elements is scanned across a portion of the image, to produce a first region or band of image or information, and then translated in a direction parallel to the linear axis of the scanning elements for another scanning operation to produce a subsequent band, slightly overlapping the previous band. The translation, relative to the photoreceptor, of the scanning array is made very reproducible by establishing the position of a moving member by reference to that of a stationary notched or indented member or members, and the resultant image is made very uniform by adjusting the data controlling the imager within the region of redundant imaging to compensate for minor but known imperfections in this stationary member.
