Abstract:
A media sheet tray includes a first media size sensor, a second media size sensor, a first circuit connected to the first media size sensor, a second circuit connected to the second media size sensor, and a switch within the second circuit. The switch can be in an open position disconnecting a continuity of the second circuit, or in a closed position maintaining the continuity of the second circuit. Media being within the media sheet tray closes the switch. Further, a combination of the first circuit connecting to the first media size sensor and the second circuit being discontinuous indicates that paper is absent from the media sheet tray.
