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.
