PRINTER AND SUBSTRATE COOLER TO KEEP THE FLATNESS OF SUBSTRATES PRINTED IN INK PRINTERS

摘要

An imaging system includes a substrate cooler that reduces the temperature of substrates that carry dried ink images. The substrate cooler has a plurality of rollers, at least one actuator, which is operatively connected to the plurality of rollers, and a control unit, which is operatively connected to the at least one actuator. The control unit is configured to actuate the at least one actuator to move the rollers relative to one another to vary the length of the path along which the substrates move through the substrate cooler.
