Abstract
An apparatus detects inoperative inkjets during printing of three-dimensional objects. The apparatus includes a roll of substrate that extends to a take up roller. A printhead prints a test pattern on a portion of the substrate pulled from the roll and the portion with the test pattern is moved opposite a digital camera. The digital camera generates data of the test pattern on the substrate and these data are analyzed to identify inoperative inkjets in the printhead.
