Abstract
Heat is transferred away from the rollers and base of a printer heater by introducing chilled water into the rollers and the base. The paper upon which print has been applied remains at an elevated temperature so that the drying of the print is not delayed. A conventional roller is modified by having an annular cavity formed in its interior and providing fluid communication between the cavity and a chiller. A conventional base is modified by the addition of a serpentine passageway formed in its interior and providing fluid communication between the passageway and the chiller. Cold water provided by the chiller to the roller prevents breaking down of oil in the bearings of the roller. Cold water provided by the chiller to the base carries the heat from the base, increasing the safety of the workplace and extending the working lifetime of the base and its related parts.
