Abstract
A method including printing a calibration pattern with a wide array printhead having a plurality of printhead dies. The method includes scanning the calibration pattern with a scanbar having a width less than a width of the wide array printhead by indexing the scanbar to a plurality of selected positions across a width of the calibration pattern and providing a scanned calibration image at each selected position, the calibration images together providing a scan of the full width of the calibration pattern, and measuring alignment between successive printhead dies based on the calibration images.
