Abstract
A web-guiding system for guiding a web of media along a transport path comprising a drive roller rotated by a motor and a plurality of nip rollers. The drive roller includes a first section, a second section and a third section along the length of the roller, the second section being located between the first section and the third section. A diameter of a surface envelope around the exterior surface of the drive roller is substantially constant within the second section, and is larger in the first section and the third section than in the second section. The nip rollers are aligned with the second section of the drive roller, with the web of media passing between the drive roller and the nip rollers.
