Abstract

Abstract A combination printer and scanner comprises a frame and a plurality of rollers mounted in the frame that define a single paper path through the frame. The combination printer and scanner further comprises an automatic sheet feeder and an automatic document feeder mounted to the frame for selectively providing clean paper print sheets and documents having text and/or graphics to be scanned, respectively, to the single paper path. A scanner station is mounted in the frame for scanning documents conveyed through the single paper path. A printer station is mounted in the frame for printing text and/or graphics on print sheets conveyed through the single paper path. A pen door is hingedly connected to the frame for opening and closing a region along the single paper path to allow access to the scanner station to permit the cleaning of a scanner window thereof. Clamping mechanisms are also provided so that the opening and closing of the pen door releases and applies tension on at least one set of rollers defining the single paper path to permit a print sheet or document jammed therebetween to be removed.
