An air diffusing vacuum transport belt including a first perforated layer
and a second non-perforated layer is provided for transporting image
carrying substrates without vacuum belt induced image defects. The first
perforated layer includes a top surface and a bottom surface, solid
areas, and perforated hole areas interspersing the solid areas for
directing pressurized airflow from the top surface through to the bottom
surface. The air diffusing vacuum transport belt also includes a second
non-perforated layer formed over the top surface of the first perforated
layer and covering the solid areas and the perforated hole areas. The
second non-perforated layer has an inner surface positioned over the top
surface of the first perforated layer, and an outer surface for uniformly
supporting substrates. The second non-perforated layer as such is porous
to air for diffusing pressurized airflow from the outer surface thereof
into the perforated hole areas of the first perforated layer, thereby
enabling transporting of image carrying substrates without vacuum belt
induced image defects.
