Abstract:
A method for aligning a printhead to compensate for printhead roll has been developed. The method includes simultaneously operating a plurality of inkjets in a printhead to eject ink drops to form a plurality of marks on an image receiving member. A plurality of cross-process direction distances between one mark formed by a reference inkjet and each of the marks formed by the other inkjets is identified. A magnitude of a difference between an angular orientation of the printhead and the cross-process direction with reference to the plurality of identified cross-process direction distances indicates any printhead roll.
