An imaging system includes a substrate cooler that reduces the temperature of a substrate bearing a dried ink image. The substrate cooler has a plurality of rollers, at least one actuator operatively connected to the plurality of rollers, and a controller operatively connected to the at least one actuator. The controller is configured to operate the at least one actuator to move the rollers relative to each other to vary a length of a path along which the substrate moves past the substrate cooler.)
