ABSTRACT:
A sheet media handling system for aligned feeding of sheet media of different widths is disclosed. This sheet media handling system caters to a wide-format printer which has two media trays, a main tray and a bypass tray positioned above the main tray. In such a printer, a larger width sheet medium in the bypass tray is insufficiently supported when a stack of smaller width sheet media is present in the main tray. Such a situation may result in skewing or jamming of the larger width sheet medium. The sheet media handling system overcomes such a problem by having a secondary pressure plate in addition to a primary pressure plate. This secondary pressure plate is moveable independently of the primary pressure plate so that the secondary pressure plate is operable to provide appropriate support for the partially supported larger width sheet medium in the bypass tray.
