Abstract
A method for aligning a printhead to compensate for printhead roll when an image receiving member moves laterally during printing has been developed. The method includes generating at different times a plurality of marks in a process direction with different inkjets in a printhead and identifying relationships between marks in each plurality. Lateral motion is thereby detected and removed from the analysis identifying the magnitude of the roll corresponding to the locations of the marks in the pluralities of marks.
