1. In a system having an operating member and an article that are alignable such that the article can be processed by the operating member, a method of establishing a predetermined alignment position between the operating member and the article before processing of the article is begun by the operating member comprising, a) supporting a laser transmitter on one of the operating member and the article, and providing the laser transmitter with means for emitting a focused laser beam, b) supporting a target means for the focused laser beam from the laser transmitter, on the other of the operating member and the article, c) providing a signaling means in cooperation with the target means to produce a detectable signal when the operating member and the article are aligned, d) providing a laser beam communication site at a selected location on the target means for receiving the focused laser beam and transmitting the focused laser beam to the signaling means to enable the signaling means to produce the detectable signal when the focused laser beam is received at the signaling means, and e) moving one of the operating member and the article to a position wherein the focused laser beam from the laser transmitter is received at the laser beam communication site for transmission of the focused laser beam to the signaling means to enable the signaling means to produce the detectable signal, whereby the production of the detectable signal by the signaling means, in response to reception of the focused laser beam at the laser beam communication site, signifies the establishment of the alignment position between the operating member and the article that is processed by the operating member.
