Document belt vacuum manifold

In a document handling system in which documents are moved on an apertured belt over a vacuum manifold to an imaging station of a copier, the vacuum manifold surface engaging the backside of the belt contains narrow, spaced apart, shallow grooves extending in the direction of movement of the belt. Vacuum is applied to the belt only through these grooves, to reduce belt/manifold friction. These manifold surface grooves have light reflective bottom surfaces closely spaced below the back of the belt to underlie the belt apertures and reduce their printout through translucent documents. The apertures in the vacuum belt are only in narrow bands overlying the grooves in the vacuum manifold. The apertures in the vacuum manifold are also preferably transversely spaced from the vacuum belt apertures so that they are not aligned during the belt movement.
