Patent ID: 8737906

Claim:
A system for determining substrate media height comprising: a media transport having a transport surface for carrying thereon substrate media along a media path in a process direction past a print zone; a media height detector disposed upstream of the print zone, the height detector including an elongate member disposed above the transport surface and extending across the transport surface in a cross-process direction, the elongate member being slanted with respect to the transport surface with a distance between the elongate member and the transport surface decreasing as the detector extends in the process direction; and the height detector including a deflection sensor operably connected to the elongate member, the deflection sensor sensing deflection of the elongate member; a reference sensor disposed upstream of the elongate member, the reference sensor sensing the presence of the substrate media; a processing device for determining media height responsive to the time difference between the media activating the reference sensor to when the media engages the elongate member.
