Patent ID: 8757746

Claim:
A printer comprising: a media transport, mounted to a first frame, configured to transport a recording media through the printer in a process direction; a printhead module, operatively connected to a second frame and disposed adjacent to the media transport, the printhead module supporting a plurality of printheads configured to print onto the transported recording media; at least one positioner operatively connected to the printhead module to adjust a gap distance between the printhead module and the media transport; a first sensor mounted at a first end of the printhead module, the first sensor being configured to generate a first signal representative of a first gap distance at the first end; a second sensor mounted at a second end of the printhead module, and the second sensor being configured to generate a second signal representative of a second gap distance at the second end; a controller operatively connected to the first sensor, the second sensor, and to the at least one positioner, to receive the first signal generated by the first sensor and the second signal generated by the second sensor, and to send an adjust signal to the at least one positioner to move the printhead module with respect to the media transport; and a first guide and a second guide, the first and the second guides being operatively connected to the first side and the second side of the printhead module, respectively, to enable linear movement of the printhead module along a predetermined path in response to the at least one positioner adjusting the first gap distance and the second gap distance.
