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.
