Abstract
A thermal processor having a contaminant removal system. The system includes a heated drum for heat developing exposed heat developable media which emit airborne contaminants during the development; a plurality of rollers located about a circumferential segment of the drum to hold an exposed media in contact with the drum; an enclosure for enclosing the heated drum and plurality of rollers, the enclosure including a first upper curved member spaced from and enclosing the rollers and the upper portion of the drum and a second lower curved member spaced from and enclosing the lower portion of the drum, the first and second curved members having first ends spaced from each other and defining a film entrance region, and further having second ends spaced from each other and defining a film exit region; wherein the first upper curved member includes a curved duct having a first opening above the rollers and a second opening configured to direct gaseous fluids away from the film exit from the drum. The system further includes a top condensation trap communicating with the second opening of the duct; a bottom condensation trap; and an air flow control system for drawing ambient air from ou…
