A method of operating a printer enables a controller in the printer to operate electrical motors for aligning printheads in the printer with greater accuracy. The method includes generating a test pattern on media with a plurality of printheads, identifying a first position for each printhead in the plurality of printheads from test pattern image data, operating an electrical motor operatively connected to one of the printheads to move the printhead in a first direction in the cross-process direction by a predetermined distance, generating a second test pattern on the media, identifying a second position for each printhead, comparing the second position of the printhead with the first position of the printhead to measure a distance moved by the printhead, identifying a first calibration parameter with reference to the predetermined distance and measured distance, and operating the electrical motor with reference to the first calibration parameter. |
