Abstract
An apparatus detects inoperative inkjets during printing operations. The apparatus includes a supply of thermal substrate that is exposed to heat to darken the substrate. The thermal substrate is printed with materials ejected from a printhead to form a test pattern. The contrast between the ejected materials and the exposed thermal substrate are imaged by an optical sensor to generate image data that are analyzed to identify inoperative inkjets.
