an image capture controller to control the image capturing device to capture an image of the test image printed on the recording medium;
a corrector to compare the image of the mark captured by the image capturing device against the predefined shape of the mark to calculate a correction value, and correct the image of the test pattern, captured by the image capturing device, based on the calculated correction value;
an inspector to perform an inspection to inspect the state of the plurality of nozzles based on the image of the test pattern corrected by the corrector;
a model specifier to specify the model of the inkjet printer based on the image of the model display portion captured by the image capturing device; and
