Abstract
Methods and apparatus for moving media along a media path employ an increase in the force with which a gripping surface contacts the media in order to compensate for wear experienced by the gripping surface. The force is increased as a function of a measured variable which can be the number of revolutions of a feed roller on which the gripping surface is defined. The variable can alternatively be elapsed time, or can be a number of sheets of media that pass a given point on the media path. An apparatus in accordance with the present invention includes a wear compensator which is configured to cause the increase in force with which the gripping surface contacts the media.
