Abstract
A method for calibration of an optical sensor to scan printed marks in a printer includes operating inkjets to form printed marks on an image receiving surface and activating the optical sensor after the image receiving surface moves a predetermined distance to generate scanned image data of a region of the image receiving surface that is longer than the region containing the printed marks. The method includes identifying an error between the location of the printed marks in the scanned image data and a predetermined expected location for the marks, and adjustment of the distance that the image receiving surface moves prior to activation of the optical sensor to correct the error.
