Abstract
An apparatus detects inoperative inkjets during printing. The apparatus operates the printhead or printheads in the printer to form test pattern on a thermal substrate. The heat of the materials used to form the test pattern change the optical density of the areas where the materials land. The area where the test pattern is formed is imaged and the image data are analyzed to identify inoperative inkjets.
