Abstract
A printer detects malfunctioning ejectors during printing of three-dimensional objects or two-dimensional printed matter. The printer operates the printhead or printheads in the printer to form convex drops of material on a substrate. A camera is positioned to minimize light reflections from the substrate into the camera. The camera is configured to generate image data of the light reflected from the substrate and specularly from the convex drops on the substrate. A controller analyzes the image data to identify malfunctioning inkjets.
