  • Document scanning apparatus with oversize document handling capability
    Patent number: 7136199
    Abstract: A document scanning apparatus which is capable of scanning an oversized document. In one embodiment the document scanning apparatus includes a base unit, an optical scanning device located within the base unit, and a cover freely removable from the base unit. The apparatus further includes a document positioning device configured to move a document with respect to the optical scanning device when the document is positioned between the base unit and the cover.

  • Method for discovering power consumption in hardcopy output device by adding idle power consumption to outputting power consumption of hardcopy output device
    Patent number: 7103787
    Abstract: The power consumption of a hardcopy output device is discovered. A page count value is gathered from the hardcopy output device. The page count value represents a number of hardcopy pages output by the hardcopy output device. The page count value is multiplied by a page power consumption value to approximate the outputting power consumption of the hardcopy output device.

  • Document reproduction
    Patent number: 6669316
    Abstract: A document is reproduced by capturing an image of the document, generating a set of vector commands, and creating a duplicate document from the vector commands. The image is captured by scanning or other suitable means. The set of vector commands is generated by identifying vectors within the raster image and for each vector identified within the raster image, generating at least one vector command for replicating the identified vector. The duplicate document is created by executing the set of vector commands on an output device. The set of vector is either delivered directly to the output device or stored to a file and the file delivered to the output device.
