Abstract
A printhead is mounted in a support frame that has reference mounting members on the sides of the frame that establish a reference plane for mounting the support frame in a printer The printhead is adjustable on the support frame relative to the reference plane about a pivot axis on the support frame and also laterally of the reference plane. A fixture is used for mounting the support frame with the reference mounting members in a known location, and the position of a print line of the printhead relative to a reference location established by a camera and monitor is adjusted until the print line is in a predetermined position. The camera provides a view of the print line relative to the predetermined position, and the printhead is adjusted on the support frame until the location of the print line viewed by the camera is at the proper position The printhead is then fixed to the support frame.
