ABSTRACT:
The present invention relates to a xerographic printer capable of reproducing microfilm or microfiche images over a broad enlargement range. The printer includes a light housing completely enclosed except for an aperture in the bottom wall. Microfilm or fiche images are successively presented adjacent this aperture. The walls of the housing are coated with a diffusely reflective material and cause light from a flash illumination source mounted within the housing to diffusely illuminate the surface of the image adjacent the aperture.
