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.
