Abstract
A non-planar single sheet separator wall preferably inclined at about 25° from the vertical away from a paper stack first engages the side corners of the leading edge of a sheet of paper or other media picked from the top of the generally horizontal or downwardly inclined stack by a roller or pusher and causes the corners of the sheet to first curl upwardly along the wall before the central portion of the leading edge of the sheet engages the central portion of the separator wall. The separator wall configuration substantially eliminates downward curling of one or both leading corners of a sheet which is purposely upwardly bowed by an elastomeric pad near the center of the separator wall to reduce multi-sheet picks and separator jams.
