Abstract
A pressure roller for a media processing device has enhanced temperature uniformity and resists temperature increases when subjected to elevated temperatures, enabling greater dimensional stability of the pressure roller in fluctuating temperatures. The pressure roller includes a hollow cylindrical member, an elastomeric layer, and an endbell on each end of the hollow cylindrical member. A chamber is defined by an inner wall of the hollow cylindrical member and the endbells in which a volume of fluid is contained to absorb heat from the hollow cylindrical member.
