Abstract
A media-guiding system includes a media-guiding roller having a roller axis and an exterior surface having one or more grooves formed around the exterior surface. A media travels along a transport path past the media-guiding roller with a first side of the media facing the exterior surface of the web-guiding roller. An air source provides an air flow into one or more of the grooves, the air flow being directed between the first side of the media and the exterior surface of the media-guiding roller thereby producing a Bernoulli force to draw the media toward the exterior surface of the media-guiding roller and providing an increased traction between the media and the media-guiding roller.
