<p>A sheet feeder apparatus having a deformable separator belt and an indexable retard roller includes a device for setting the proper depth of penetration of the retard roller into the deformable belt in the form of a flat surface on the periphery of the roller. In use, a deformable separator belt is placed in the sheet feeder over the flat surface of and adjacent to the retard roller. The proer penetration depth of the retard roller into the deformable belt is subsequently set by indexing the retard roller to present a non-flat surface adjacent the deformable belt.</p> |
