In an electrophotographic printing machine, a photoconductive belt is supported by a belt support frame. The frame is mounted slidably in the printing machine. In this way, the photoconductive belt may be readily removed from the printing machine. When the belt module is removed from the printing machine, the supports are designed to be movable so as to relax the tension on the photoconductive belt enabling the photoconductive belt to be readily removed from the support frame for subsequent replacement. As the frame is slidably removed from the printing machine, it actuates a camming mechanism which pivots the corona generating devices away from the surface of the photoconductive belt. This prevents damage of both the corona generating devices and the photoconductive belt. After a new photoconductive belt is placed on the support frame, the support frame is returned to the printing machine. As the support frame slides into the printing machine, it actuates the cam which returns the corona generating devices to the operative position with respect to the photoconductive belt. In this way, the photoconductive belt may be readily removed from the printing machine and replaced. A system of this type automatically positions the photoconductive belt with respect to the various processing stations within the printing machine and cams the processing stations from their operative position to an inoperative position preventing damage of the photoconductive belt.
