Abstract
An inkjet printer includes a dryer configured to attenuate cockle in the substrates under the heater of the dryer and reduce ink transfer from ink images during duplex printing without adversely affecting the cooling of the substrates exiting the dryer. The dryer has at least two plenums with at least one plenum opposite a heater and at least one plenum opposite an air vent. A platen covers the plenum opposite the air vent and the platen has a plurality of protuberances arranged in a non-linear arrangement so the protuberances contact substrates being carried by a plurality of endless belts over the plenum to prevent the substrates from contacting a surface of the platen. Another platen covers the plenum opposite the heater and this platen has non-linear members on its surface to support the substrates and reduce cockle while the ink is dried by the heater.
