ABSTRACT:
An electrophotographic-type imaging station or printer includes a focusing lens positioned between the printer light source and a photosensitive medium. As the light source projects beams of light energy forming a row in a direction towards the photosensitive medium, the lens focuses each projected beam into a rectangular beam. The speed of the photosensitive medium and the operation of the light source are coordinated so that adjacent rows of generally rectangular beams are positioned in abutting relation with each other. The plurality of focused rows projected in row-at-a-time fashion onto the surface of the photosensitive medium form an informational array pattern having a resolution in a direction parallel with the direction of medium movement which is greater than the resolution of the pattern in a direction perpendicular to the direction of medium movement. By forming an informational array pattern in this manner, a desired informational array pattern gray scale may be achieved without a loss in the original resolution of the array pattern taken in a direction perpendicular to the direction of medium movement.
