Claim:
1. A non-transitory computer readable medium embodying programmed instructions executable by a processor, the instructions operable to direct the processor to: dry a colorant applied to a print medium in contact with a portion of an outside surface of a thermally conductive drum utilizing a plurality of radiant energy sources that are disposed across from the portion of the outside surface of the drum; apply a coolant to an interior surface of the drum utilizing a plurality of cooling jets to remove heat from the drum, wherein the cooling jets direct the coolant onto regions of the interior surface of the drum that are substantially opposite to areas on the outside surface that receive a peak heat flux from the energy sources; measure a temperature of the drum; determine a difference between the temperature of the drum and a target temperature; and vary an application of the coolant to the drum based on the difference to maintain the drum at the target temperature.
