Abstract
A sheet separating mechanism and a method of separating sheets that includes a retard surface carrier that causes a retard surface to apply an alternately higher and lower friction force against the edge of an underlying sheet. The alternation of the higher and lower friction force can be coupled to a vacuum sheet feeder. The retard surface can be translated to present a next portion of the retard surface to the edge of the next underlying sheet with the translation coupled to the vacuum sheet feeder.
