Abstract
In a reproduction apparatus including an image receiving member, at least one support for mounting the image receiving member for movement along a travel path, and an electronic light emitting print head assembly including a focusing lens, a simplified mechanism for accurately locating an electronic print head assembly relative to the image receiving member, which enables the image receiving member to be readily changed and which does not impact tracking of the member. The mechanism comprises a frame with the print head assembly mounted at a preselected location in the frame. A first feature is defined in the frame, the first feature including a locating surface spaced at a preselected distance from the plane through the geometric center line of the focusing lens of the print head assembly. Also, a second feature is defined by the frame, the second feature including a pair of interconnected locating surfaces, the first of the pair of locating surfaces spaced at a preselected distance from the plane through the geometric center line of the focusing lens, and the second of the pair of locating surfaces spaced at a preselected distance from the image plane of the focusing lens. The fr…
