Abstract
A printer detects inoperative inkjets during printing of three-dimensional objects. The printer includes an area where a printhead ejects material in a predetermined pattern and a profilometer is operated to measure the ejected material in the area. The measurements are used to identify inoperative inkjets or inkjets that operate errantly.
