Abstract

Described are techniques for preventing the forces attributable to shrinkage of print media from shifting print media on the media-carrying belt in the vicinity of the print zone. In one approach, a “hold zone” is identified immediately upstream of the print zone. In the hold zone, a mechanism is employed for securing the media to be immovable relative to the belt. The hold mechanism provides sufficient force to overcome tension transmitted to the dry portion of the media as the remaining portion shrinks. In one embodiment, the hold mechanism is a roller that pinches the media against the belt. In another embodiment, the amount of vacuum pressure applied to the belt is regulated so that the suction force applied to the media in the hold zone is greater than the suction force applied to the media in the portion upstream of the hold zone.
