ABSTRACT:
A paper handling apparatus includes a tray for supporting a stack of cut paper sheets. The tray includes at least one hinged portion. A feed roller is disposed above the tray for selectively feeding sheets seriatim from the stack of cut paper sheets. The paper handling apparatus further includes a stack flexing mechanism for pivoting the hinged portion of the tray to flex the stack of paper without bringing the paper into contact with the feed roller. This conditioning of the paper stack may reduce misfeeds or multifeeds from the paper stack.
