Abstract:
A method for moving print media includes providing a vacuum assembly having an arcuate profile to deflect the print media such that the print media has a non-linear profile in a direction perpendicular to a media travel path. A roller, having an axis of rotation and a diameter, and including three sections with the second section located between the first and third section as viewed along the rotational axis is provided. The diameter of the roller in the first and third sections is greater than in the second section. The roller is used to deflect the web of print media in a direction opposite to that of the deflection of the web of print media by the vacuum assembly, thereby spreading the web of print media in a cross-track direction to reduce the formation of wrinkles in the web of print media as it travels over the roller.
