Abstract
A method and apparatus for preventing excess spin of idler rollers after a sheet of paper or other media has passed a media guide with the idler rollers including a retard function within plastic idler rollers. The retard function is provided by adding a retard flexure molded into the idler roller. This adds a brake which stops excess over spin of the idler rollers.
