ABSTRACT:
A method and mechanism are provided for supporting and stacking a liquid ink printed sheet moving along an in-track path and direction in a liquid ink printing system and having a flat, cross-track dimension "D1" defined by a first edge and a second and opposite edge of such sheet. The mechanism for the method includes an output tray defining and providing a stacking surface for holding the liquid ink printed sheet in a stack; and a first member having an edge supporting portion and an edge guiding portion for supporting and guiding the first edge of the liquid ink printed sheet, the first member being mounted at a first position having a first desired height distance above the stacking surface, and the first member extending along the in-track path and direction. The mechanism for the method also includes a second member having an edge supporting portion and an edge guiding portion for supporting and guiding the second and opposite edge of such sheet, the second member being mounted at a second position having the first desired height distance above the stacking surface, and being spaced a cross-track distance "D3", that is less than "D1", from the first member, and the second member extending along the in-track path and direction. Finally, the mechanism for the method also includes a system for rotating the first member and the second member for buckling the liquid ink printed sheet downwardly through the first desired height distance, and through the cross-track distance "D3" onto the stacking surface of the output tray.
