Abstract
A method of an embodiment of the invention is disclosed that advances media sheets through an image-forming device such that each successive pair of media sheets are advanced at least substantially adjacent to one another. The method transmissively optically senses a leading edge of each of the media sheets and a lagging edge of each of the media sheets. The method detects occurrence of an out-of-media sheets situation where a length of time after the lagging edge of one of the media sheets has been optically sensed exceeds a threshold length of time.
