ABSTRACT:
A print head position control system for a printer in which a print head moves along a track and in which a light source illuminates along the track and a photodetector receives the light to produce a control signal in proportion to the position of the print head in relation to the light. A print head mount electromechanically adjusts the position of the print head in response to the control signal, so that the path of the light automatically controls the print head path along the track.
