Multiple images may be written simultaneously onto at least one photosensitive surface by modulating first and second laser beams in accordance with image information corresponding to first and second images. The first beam is directed onto a scanning mirror at a first angle of incidence A.sub.1, and the second beam is directed onto the same scanning mirror at a second angle of incidence A.sub.2. The first beam is focussed from the scanning mirror onto the photosensitive surface to write the first image thereon. The second beam is focussed from the scanning mirror onto the liquid crystal surface to write the second image thereon spatially remote from the first image.

An original document exposure device utilizes a bump exposure to control contrast by reducing the contrast in a reproduction image of the original document. The bump exposure is achieved by covering a portion of the field of view of the focusing system of an exposure lamp with a diffuse reflector. A portion of the exposure light is thus diffusely reflected into the focusing system and onto the photosensitive media. The degree of bump achieved is controlled by position adjustment of the reflector.
