Abstract

Provided is a document copier having an input transport mechanism and an output transport mechanism linked via a media path, the mechanisms configured to feed sheets of media through the media path. Also included is a print engine located in the media path for printing on media fed through the media path, and a code sensor arranged before the print engine in the media path, said sensor configured to capture images of a sheet surface. The copier also includes a controller for controlling the transport mechanisms, the print engine and code sensor. The controller decodes optical patterns found in the captured images to obtain one or more codes able to identify an electronic source where an electronic copy of the sheet is stored, and to print the electronic copy on a blank sheet of media with the print engine.

Claims

1. A document copier comprising:

a sheet transport mechanism configured to feed sheets of media through a media path;

a print engine located in the media path for printing on sheets of media fed through the media path;

a code sensor for sensing coded data on a surface of a source page, the source page containing the coded data and content; and

a controller for receiving sensed coded data, for retrieving an electronic document identified from the sensed coded data, and for controlling the sheet transport mechanism and the print engine to print the electronic copy on a blank sheet of media, the electronic document when printed containing the content of the sorce page.

2. The document copier of claim 1, wherein the code sensor is in the media path and the sheet transport mechanism is further configured to feed one or more source pages through the media path for sensing by the code sensor.

3. The document copier of claim 2, wherein the code sensor is arranged upstream of the print engine in the media path.

4. The document copier of claim 1, wherein the coded data comprises patterns printed on the source page and the code sensor images the source page.

5. The document copier of claim 4, wherein the code sensor includes a light source, projection and image capture optics, and an image sensor.

6. The document copier of claim 1, further including a document binding mechanism at an end of the media path for binding printed sheets together.

7. The document copier of claim 6, wherein the binding mechanism includes a glue applicator and a stamping mechanism for stamping glued sheets together.

8. The document copier of claim 1, wherein the print engine includes dual printheads arranged in a duplex printing arrangement.
