A system for handling media sheets is provided which comprises a plurality of hardware components including a first image marking engine operative to mark media sheets, and a second image marking engine operative to mark media sheets. In addition, the plurality of hardware components can include a first object delivery path operative to transport media sheets presented by the first image marking engine to a first destination, and a second object delivery path operative to transport media sheets presented by the second image marking engine to a second destination. The first and second destinations may be a single destination, separate destinations, or interchangeable destinations. One of the first and second delivery paths can be redundant. At least one of the first and second delivery paths includes a hyper module for transporting a series of diagnostic media sheets in both forward and reverse directions through a first recursive loop through the plurality of hardware components within the system during a diagnostic sequence whereby a fault is detected.
