Abstract

Proposed is a dip coating chuck that holds a photoreceptor substrate by contact with an expandable air bladder. As shown in the accompanying figure, variable sized chuck 10 comprises a plurality of bladders 14, 16, and 18. The bladders 14, 16, and 18 accommodate substrate diameters in the range of 30 to 60 millimeters. Specifically, bladder 14 holds a 30 millimeter substrate. Bladder 16, holds a 40 millimeter substrate, and bladder holds a 60 millimeter substrate. Bladders 14, 16, and 18 are shown in a relaxed (closed) state. However, multiple air passages 20, 22, and 24 connect to valves 26, 28, and 30 to inflate the bladders to their expanded (chucking) positions 15, 17, and 19. One skilled in the art will recognize that other bladder sizes or combination of bladders can be accommodated for other substrate sizes.
