Abstract: An aqueous ink printer is operated to insert media sheets from a first supply tray into a plurality of media sheets from a second tray on which ink images are being formed by the printer to absorb condensed vapors on media guides. The media sheets from the first tray are uncoated media and the media sheets from the second tray are coated media. In some embodiments, the inserted media sheets are printed with an ink image that has areas that contact the media guides with a greater ink density than other areas of the ink image that do not contact the media guides. Additionally or alternatively, the inserted media sheets are printed with an ink image that has areas that contact the media guides with an ink color that is different than an ink color used in other areas of the ink image that do not contact the media guides.

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.
