1. An articulating sheet guide, for use in connection with a printing system having a process direction, a media sheet source, and a media sheet having opposite top and bottom surfaces, the media sheet having a leading edge and an opposite trailing edge, the media sheet having a predetermined width along the leading edge, the articulating sheet guide comprising:
a primary media transport adjacent the media sheet source; a secondary media transport downstream of the primary media transport; a link having at least one elongated element, the link having a front surface facing generally upstream of the process direction and an opposite rear surface, the link extending from a proximal end to a distal end, the link proximal end being pivotally mounted on the printing system for pivotal movement on a pivotal axis of the link from a starting position adjacent the primary media transport toward the secondary media transport to an ending position, wherein the link comprises exactly four bars; and at least one link pocket disposed transversely to the process direction on the link front surface, the link pocket being adapted to receive the media leading edge; so that the primary media transport will move the media sheet from the media sheet source toward the link, the link pocket will receive the media leading edge adjacent to the primary media transport, the media sheet movement will cause the link to move pivotally, the media sheet will move along an arcuate path guided by movement of the link pocket resulting from the pivotal movement of the link, the link pocket will guide the media sheet into engagement with the secondary media transport and, thereafter, the link pocket will release the media leading edge. |
