Abstract
A web-guiding system for guiding a web of media along a transport path including a web-guiding roller located in proximity to a fixed web-guiding structure having a pattern of air holes formed through its exterior surface. The web of media travels around the web-guiding roller with the web of media contacting the web-guiding roller through a wrap angle of less than 5 degrees, and travels around the fixed web-guiding structure through a wrap angle of more than 10 degrees. An air source provides an air flow through the air holes formed lifting the web of media away from the web-guiding structure such that the web of media is substantially not in contact with the web-guiding structure.
