Apparatus for reducing wrinkles in moving web

An apparatus for moving a continuous web of print media comprising:

• a roller having an axis of rotation and a diameter, the roller including a first section, a second section, and a third section, the second section being located between the first section and the third section as viewed along the axis of rotation, the roller including a profile as viewed along the axis of rotation in which the diameter of the roller in the first section and the diameter of the roller in the third section are each greater than the diameter of the roller in the second section;
• a vacuum assembly having a plurality of vacuum manifolds arranged in an arcuate configuration to provide a first section, a second section, and a third section, the second section being located between the first section and the third section, the arcuate configuration of the vacuum assembly including an extremum point located in the second section, the plurality of vacuum manifolds providing a vacuum force proximate to the first side of the movable print medium;
• and
• the vacuum assembly being positioned along a media travel path immediately upstream relative to the roller, the first section, the second section, and the third section of the configuration of the plurality of vacuum manifolds corresponding to the first section, the second section, and the third section of the roller such that the contour of the arcuate surface causes the web of print media, after leaving the vacuum assembly, to have a non-linear profile in a direction perpendicular to the media travel path so 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.
