Abstract
A test image printer of an inkjet printer causes a test image, including a mark with a predefined shape and usable to correct an image captured by an image capturing device, and a test pattern usable to inspect a plurality of nozzles, to be printed on a recording medium. An image capture controller controls the image capturing device to capture an image of the test image printed on the recording medium. A corrector compares the image of the mark captured by the image capturing device, to the predefined shape of the mark, to calculate a correction value, and corrects the image of the test pattern, captured by the image capturing device, based on the calculated correction value. An inspector inspects the plurality of nozzles based on the image of the test pattern corrected by the corrector.
