Abstract: A translateable media height sensor assembly for measuring a media stack height in an imaging forming device. The assembly includes a support and drive and insertion assemblies mounted thereon. The insertion assembly includes a translateable plunger having mounted thereon a sensor and a translateable probe. At a home position the sensor is actuated by a flag on the support placing sensor output in a first state. During measurement, the drive assembly translates the insertion assembly toward a media stack and the sensor output changes to a second state and a counter is started. The probe encounters the media stack and stops while the plunger and the sensor continue to translate with the probe engaging the sensor causing the sensor output to again change state and stop the counter. The insertion assembly retracts back to the home position where the flag actuates the sensor causing the sensor output to change state.

Abstract: A method using a media height sensor assembly for measuring a media stack in an imaging device. The assembly includes a support and drive and insertion assemblies mounted thereon. The insertion assembly includes a translateable plunger having a sensor and a translateable probe. At a home position, the sensor is actuated by a flag on the support placing a sensor output in a first state. During measurement, the drive assembly translates the 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 translates in a direction opposite to that of the plunger. As the plunger reaches the media stack, the probe causes the sensor output to again change state stopping the counter. The insertion assembly is retracted to the home position where the flag causes the sensor output to change state.

Abstract: A method of using a 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 a measurement cycle, 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 translates in a direction opposite that of the plunger. As the plunger reaches the media stack, the probe causes the sensor output to again change state stopping the counter. The insertion assembly is retracted to the home position where the flag causes the sensor output to change state.
