Abstract
An apparatus detects inoperative inkjets in a printhead. The apparatus includes a rotating member having a light transmitting surface layer onto which material is ejected by the printhead. A light source directs light into an edge of the light transmitting surface layer at a position on the circumferential perimeter of the surface layer and an optical sensor generates image data of the surface of the surface layer of the rotating member. Inoperative inkjets are detected with reference to the image data of the surface of the surface layer of the rotating member.
