Print media transport apparatus for moving print media through a printer from a high volume input tray accessory

A print media transport apparatus for transporting sheets of print media from a high volume auxiliary media input tray and for introducing said sheets into a printer media transport path extending from an individual sheet reception slot to a print zone of a printer, said apparatus comprising:

• a) a tray cabinet having an upper surface for supporting a printer thereon and having a receptacle in said cabinet for receiving a print media tray moveable into and out of said cabinet along a path extending from a first side of said cabinet toward a second side of said cabinet;
• c) means in said cabinet for moving individual print media sheets from the top of a stack of sheets in said tray toward said second side of said cabinet;
• d) a convex print media guide moveable between an operative position in which said guide extends upwardly from said cabinet and an open position in which said convex guide extends generally in the direction of movement of said print media tray, said guide being movably connected to said cabinet proximate said second side of said cabinet;
• e) a print media guide housing moveable between an operative position in which said housing extends upwardly from said cabinet and an open position in which said housing extends generally in the direction of movement of said print media tray, said housing being movably connected to said cabinet at said second side, said housing having a concave print media guide surface therein spaced from said convex print media guide, said convex guide and said concave housing surface, when in operative position, defining a curved print media path therebetween terminating at a discharge end, said housing substantially enclosing said print media guide;
• f) means for moving individual sheets of print media along said print media path;
• and
• g) a print media pre-heater affixed to one of said guide and said housing proximate said print media discharge end.
