Abstract
Embodiments described herein provide rollers that cool a print medium downstream of a dryer while minimizing the temperature differentials across the print medium. In some embodiments, air is directed through the interiors of different rollers in opposing directions based on a pattern to reduce the temperature differential across a width of the print medium. In other embodiments, a controller alternates a direction of the air through the interior of a roller to reduce the temperature differential across the width of the print medium.
