Abstract
A sheet stacking system is provided which includes mechanism designed to compensate for the aerodynamic forces which act on a sheet as it passes from the printer's output port to the floor of the printer's output tray. The system includes a pair of spaced, anti-sail wings which are positioned adjacent the printer's output port so as to controlledly receive just-expelled sheets. The wings are operatively associated with the output tray's floor, and are arranged so that opposite movement thereof results in rear-to-front sequential release of a supported sheet, directing substantially vertical passage of such sheet to the top of an output stack.
