ABSTRACT:
A cooling system is provided for a thermal print head that has a thermal dye transfer portion and a rear surface. The cooling system includes a bracket defining an open reservoir, and is attached to the print head so that the rear surface of the print head closes the reservoir. Cooling fluid is pumped into the reservoir and brought into contact with the rear surface to effect cooling of the print head. The bracket is removably attached using bolts with o-rings and a sealing gasket interposed between the bracket and print head.
