Abstract
A sheet feeding method is disclosed that provides two feed strokes for each feed cycle. Each sheet may be fed during the first stroke. In the event, however, that the sheet fails to feed during this first stroke, the second stroke of the cycle will enable the sheet to be fed. The sheet feeding device comprises an over-head feed roller that is biased into contact with the top sheet of a stack of sheets. The feed roller has forward courses and a backward course of travel during each feed cycle.
