Abstract
An input roller pushes the media through the electrophotographic device at a given linear velocity. An output roller pulls the media through the electrophotographic device after the media leaves the input roller. The output roller has a linear velocity greater then the input roller's linear velocity. In-between the input and output rollers is a variable media path having an arcuate shape. A compressible media guide is placed along the concave side of the variable media path. As the media is pulled faster by the output roller, the variable media path decreases. The compressible media guide begins to compress thereby creating a constant tension in the media as it passes through the electrophotographic device. By keeping the media under a constant pressure, the likelihood of deformations is greatly reduced.
