Abstract
A replaceable unit for an electrophotographic image forming device according to one example embodiment includes a housing having a reservoir for storing toner. A rotatable shaft is positioned within the reservoir. A paddle is mounted on the shaft. A sensor is positioned on the housing outside of the reservoir and positioned to sense a rotational motion of the paddle when the shaft rotates. A processor is mounted on the housing and in electric communication with the sensor. An electrical contact is in electric communication with the processor and exposed on an exterior of the housing unobstructed to mate with a corresponding electrical contact when the replaceable unit is installed in the image forming device.
