Patent ID: 7756428

Claim:
A method for handling media sheets, the method comprising: providing a plurality of hardware components including: a first image marking engine operative to mark media sheets; a second image marking engine operative to mark media sheets; a first media sheet delivery path allowing for the transportation of said media sheets marked by the first image marking engine to a first destination; a second media sheet delivery path allowing for the transportation of said media sheets marked by the second image marking engine to a second destination, wherein the first and second destinations may be a single destination or separate destinations; using at least one of said first and second delivery paths including a hyper module for selectively transporting a series of diagnostic media sheets in both forward and reverse directions through a first recursive loop in said forward direction through the plurality of hardware components, wherein said hyper module selectively transports said series of diagnostic media sheets from said first image marking engine to said second image marking engine and from said second image marking engine to said first image marking engine, within a system during a diagnostic sequence whereby a fault is detected; and, transporting said series of diagnostic media sheets through a second recursive loop, wherein said second recursive loop is a subset of said first recursive loop excluding at least one hardware component of the plurality of hardware components from said first recursive loop to determine if said fault is isolated to said excluded at least one hardware component; and, selectively continuing to exclude at least another hardware component from the plurality of hardware components with at least another subsequent recursive loop until said fault is isolated, wherein said at least another subsequent recursive loop is a subset of each previous recursive loop.
