Abstract
An apparatus detects inoperative inkjets during printing of three-dimensional objects. The apparatus includes a supply of substrate that is pulled to a position opposite a printhead to enable a test pattern of material to be formed on a portion of the substrate. That portion is then pulled past a laser sensor, which generates measurement data of the material on the portion of the substrate bearing the test pattern. These measurement data are analyzed to detect inoperative inkjets.
