ABSTRACT:
Sheet feeding apparatus and method for reliably feeding sheets from a column of sheets. The sheet feeding apparatus includes separation tangs each having a step-wise topography of reduced contact area for the sheets in order to reduce frictional drag on the sheets as the sheets are fed into an imaging apparatus. This allows for reliable feeding of the sheets because the reduced contact area of the separation tangs reduces contact time, as well as frictional drag, with the separation tangs. Moreover, the step-wise topography of the tangs individually separates each sheet from the column of sheets to be fed into the imaging apparatus in order to avoid multiple-feeding of the sheets.
