  • Publication number: 20150102085
    Abstract: A translatable media height sensor assembly for measuring a media stack in an imaging forming device. The assembly includes a support and drive and insertion assemblies mounted thereon. Insertion assembly includes a translatable plunger having mounted thereon a sensor and a translatable probe. At a home position, the sensor is actuated by a flag on the support placing sensor output in a first state. During measurement, drive assembly translates insertion assembly toward a media stack and the sensor output changes to a second state and a counter is started. The probe initially encounters the media stack and stops while plunger continues to translate. As the plunger reaches the media stack, the probe engages the sensor causing the sensor output to again change state and stops the counter. The insertion assembly retracts back to the home position where the flag actuates the sensor causing the sensor output to change state.
