ABSTRACT:
A printer table including a series of angled jets for sources of air and for sources of vacuum and also including a set of locating pins. The combination enables the use of the directed jets to move a substrate into position for processing and to hold the substrate in position once located by the locating pins with the use of a vacuum. Because the substrates are very thin and the locating pins are very short, the combined use of the vacuum and directing jets effectively permit the substrate to float on air in close proximity to the table surface while not overriding the locating pins.
