Abstract
A method for detecting a defect in an inkjet print head within an inkjet marking device includes marking images on a rotating intermediate substrate according to an image sequence, marking a test image on at least one blank portion of the intermediate substrate, the blank portion resulting from the image sequence, evaluating the test image with a sensor, and determining whether the inkjet print head is defective based on the evaluation.
