Embodiments herein include a printing or copying device that includes a media transport belt and a vacuum manifold. The vacuum manifold has an air intake positioned adjacent the media transport belt and has a vacuum blower or other air moving device that forces air out an air outlet of the manifold. The vacuum blower forces air from the vacuum manifold through the air outlet to create vacuum within the manifold. The vacuum manifold also includes transport belt openings that are sized, shaped, and positioned to allow the transport belt to pass into the vacuum manifold. The media transport belt is positioned partially within, and partially outside the vacuum manifold, such that the media transport belt is positioned to move through (within) the vacuum manifold from a first transport belt opening to a second transport belt opening.
A signature booklet making apparatus for an electrophotographic printing machine, the booklet making machine having a trimmer blade blower and high capacity waste bin. Selectively operable air ducts are provided to distribute an airflow either across the trim blade to remove trim scraps or through a bypass duct to efficiently fill the waste bin with scrap. A valving mechanism responsive to the operation of the trimmer directs the airflow to the correct duct. By selectively causing the air to flow across the trim blade the chance of forcing thin booklets into the waste chute thereby causing jams is minimized.
