  • Printed medium with integral image locator and method
    Patent number: 6688717
    Abstract: A sheet of inkjet printed photographic images having orthogonal fiducial marks extending along a leading edge of the printed field and along a lateral side of the printed field. The fiducial marks register with the printed field and provide information regarding the location of the images in the printed field relative to the larger sheet. The registration of the lateral side fiducial mark and print field is accomplished by exercising the nozzles of the print head at each pass of the print head during the printing of the photographic image.

  • Print cutter calibration method and apparatus
    Publication number: 20030145750
    Abstract: A cutter having a plurality of stepper motor driven rollers has various components needing calibration to insure that a sheet printed with a plurality of images is properly positioned with respect to the cutter for cutting the sheet into individual prints. A calibration print having a plurality of fiducial marks is used to calibrate various components. These include adjusting the intensity of scanners used by the cutter to locate the prints, to adjust the linear distances the print is moved by drive rollers and to determine precisely the distance between critical components of the cutter.

  • Method of exercising nozzles of an inkjet printer and article
    Patent number: 6505906
    Abstract: A method providing for the exercise of one or more nozzles of an inkjet print head and simultaneously forming fiducial registration marks on a sheet of print medium. The exercising and forming of the fiducial registration marks both occur in the course of forming inkjet printed images on the sheet of print medium so that the prints and fiducial marks are in registry. Preferably exercising of the nozzles occurs at the beginning and end of each pass of the print head so that there are two such fiducial marks, one along each lateral edge of the image. A segment of a print medium including printed images and a fiducial mark composed of the exercise of the inkjet print head nozzles is also disclosed.
