Claim One:
1. A method for analyzing image data of a test pattern generated by a printer comprising: identifying an origin position in the test pattern image data with reference to an origin identified by test pattern template data stored within a memory of the printer; identifying first inkjet positions for printheads that produce the test pattern in the test pattern image data with reference to first inkjet positions for the printheads identified by the test pattern template data stored within the memory of the printer; identifying last inkjet positions for printheads that produce the test pattern in the test pattern image data with reference to last inkjet positions for the printheads identified by the test pattern template data stored within the memory of the printer; identifying spatial differences between the first inkjet positions in the test pattern image data and the first inkjet positions identified by the test pattern template data stored within the memory of the printer; identifying spatial differences between the last inkjet positions in the test pattern image data and the last inkjet positions identified by the test pattern template data stored within the memory of the printer; and operating an actuator to move at least one printhead used to produce the test pattern in response to the identified spatial difference corresponding to the first inkjet or the last inkjet of the printhead not being within a predetermined range.
