<p>By exchanging the print head cartridge of an inkjet (bubble jet) printer (1) with a CCD image sensor (2), an apparatus capable of scanning and digitising optical images - the reverse process of printing - is provided. While a document is fed into the printer (1), the printer (1) is commanded to 'print' by a host computer (4), passing the print head platform which holds the CCD image sensor (2) across the document horizontally and feeding the document vertically. As the CCD image sensor (2) is scanning the document, images on the document are digitised and fed to the host computer (4). The CCD image sensor (2) and its support circuitry are in a similar housing as the print head cartridge, making it easily exchangeable. The printer (1) recovers its normal function when the print head cartridge is put back.</p> |
