Electrostatographic reproduction machine including optics assembly

Abstract

In an electrostatographic reproduction machine having a charged imaging member and an optics assembly for forming a properly registered latent image on the charged imaging member, a quick and precise optics assembly realignment tool mounted removably within the machine for realigning the optics assembly, after repair or remanufacture of such optics assembly. The realignment tool includes a generally rectangular frame having four sides forming four corners, and three non-adjustable position leg members, that are formed integrally with the frame at three of the four corners for initially locating and referencing the frame relative to a reference surface within the machine. The tool also includes one adjustable position leg member mounted slidably for adjustable movement at a fourth corner for initially compensating for any runout of the reference surface, so as to achieve a properly aligned optics assembly within the machine. The tool further includes first and second adjustable position finger members mounted slidably on a first and a second, opposite sides, of the four sides, and between leg members, for firmly setting an aligned position of a second carriage of the optics assembly relative to a first carriage thereof. The first and the second adjustable position finger members, and the adjustable position leg member, are mounted slidably within a first and a second slot portions in a bottom surface of the frame. Further, the adjustable position leg member and the first and the second adjustable position finger members, each include means for firmly binding each to the frame so as to cooperatively with the non-adjustable position leg members, firmly set positions of the first and the second carriages respectively, when properly aligned, relative to the reference surface within the machine.
