Abstract
A cut sheet stacking system receives and stacks cut sheets in registry against intersecting registration surfaces. The system comprises a sheet support surface, and first and second planar registration surfaces which extend upwardly from the sheet support surface and intersect to form a 90.degree. angle of intersection therebetween. A roller having a flexible tab is rotatably mounted above the sheet support surface and is positioned to frictionally engage a topmost sheet of a stack on the sheet support surface. The roller/tab exerts a force on the topmost sheet in a direction that intersects the first and second planar registration surfaces at their point of intersection and, when rotated, imparts forces on the topmost sheet which directs it towards the intersecting first and second planar registration surfaces.
