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.
