Abstract: An imaging system in a copier is modified so as to scan original documents at speeds differing from the image medium speed through the exposure zone so as to anamorphically reduce or enlarge the projected image. A two process scanning operation results in an output image reduced or enlarged in two dimensions. Resolution is maintained by forming an effective imaging width of approximately 1 mm by using a combination of a lens array providing a narrow irradiance profile with an optically aligned slit of smaller width. Magnification values of from 0.50 to 1.5 are thereby enabled.

Abstract: An electrophotographic reproducing machine having a photoconductive belt, a fixed platen for supporting an original document, and a translatable carriage having, fixedly mounted thereon in fixed relation to each other, a corona generating device for charging the belt, a document scanner for scanning the document on the platen and producing a latent image thereof on the belt, a transfer device for transferring the latent image from the belt to a dielectric sheet, and a roller about which the belt is entrained. One end of the belt is held, so that, as the carriage is translated, the belt is charged and the document is scanned and a latent image is formed onto the stationarily held portion of the precharged belt near the carriage roller. The other end of the belt is attached to a takeup roll which keeps the belt taut around the carriage roller as the carriage moves in the scanning direction.
