Abstract:
1. A method for reducing the formation of wrinkles in a continuous web of print media in a printing system, comprising: providing a non-rotating transport member having an operative surface; providing an air clamp; disposing the air clamp proximate to a leading surface of the transport member to control the air flow in the gap between the operative surface of the transport member and a first side of the web of print media; using the transport member to deflect the web of print media moving through the printing system such that the web of print media has a non-linear profile in a direction perpendicular to a media travel path as the web of print media leaves the transport member; providing a roller having an arcuate profile downstream of the transport member such that the web of print media contacts the first section and the third section of the roller prior to contacting the second section of the roller, and wherein the web of print media wraps around the roller with a high wrap angle; and using the roller to deflect the web of print media in a direction opposite to that of the deflection of the web of print media by the transport member, thereby spreading the web of print media in a cross-track direction to reduce the formation of the wrinkles in the web of print media as it travels over the roller.
