Patent ID: 8292398

Claim:
A method for analyzing image data of a test pattern generated by a printer comprising: identifying a first cross-process position for each printhead in a plurality of printheads in a printer, the first cross-process positions being identified with reference to image data of a test pattern printed by the plurality of printheads on a media substrate as the media substrate passes the plurality of printheads in a process direction; identifying a second cross-process position for each printhead in the plurality of printheads; calculating a printhead cross-process position error between the identified first cross-process position and the identified second cross-process position for each printhead; comparing a maximum printhead cross-process position error to a predetermined threshold; and operating a plurality of actuators with reference to the calculated printhead cross-process position errors to reposition the printheads in the plurality of printheads in response to the maximum printhead cross-process position error being equal to or less than the predetermined threshold.
