Abstract: This invention relates to media sensors for multipurpose (MP) trays. MP trays are, typically, located along a side of a printer and allow the user to install a variety of media, such as transparencies, which can be printed by the printer. Such structures of this type, generally, provide immediate visual/audio feedback to the user regarding whether or not the media was properly installed in the MP tray.

Abstract: An imaging media tray is provided for use in an imaging system having a housing. The tray includes an imaging media holding portion adapted and constructed to retain imaging media in position for processing by the imaging system. At least one tray closure element is movably connected directly to the imaging media holding portion. The at least one closure element is movable between a first, open position permitting insertion of imaging media into the imaging media holding portion without movement of the imaging media holding portion with respect to the housing of the imaging system, and a second, closed position in which the imaging media is in position for processing by the imaging system. In an embodiment, the at least one tray closure element is provided as a door having a generally rectangular cross-section including a top, a bottom, a left side, and a right side. The left and right sides of the door have a height that is substantially less than a length of the top and bottom.
