An apparatus for first aligning by trial and error, and then mounting or fastening a subsystem of an electrostatographic copier or printer such that the subsystem thereafter can be removed, serviced, and then remounted or reinstalled in precise alignment without further need of such initial trial and error aligning thereof. The apparatus include an aligning device for initially aligning by marking an aligned position through a first alignment and screw mounting aperture in the mounting portion of the subsystem, and for forming a laterally sealed cavity with such mounting portion. The device has front and back sides, a screw or bolt mounting apertures therethrough, a backside recess, and adhesive introduction perforations therein. The apparatus also include a mounting or fastening means such as a mounting screw, and an adhesive for permanently bonding the aligning device to the mounting portion, thereby also permanently aligning and marking the aligned position through the mounting portion such that the subsystem thereafter can be removed, serviced, and then remounted or reinstalled in precise alignment without further need of such initial trial and error aligning thereof.
