Abstract: A method for estimating an amount of toner remaining in a reservoir of a replaceable unit for an image forming device according to one example embodiment includes receiving by processing circuitry pulses from a magnetic sensor. Each pulse is indicative that the magnetic sensor detected a magnet on a moving paddle positioned in the reservoir. The processing circuitry counts the number of the pulses received from the magnetic sensor. Upon receiving a request from a controller of the image forming device, the processing circuitry sends to the controller of the image forming device the count of the pulses received from the magnetic sensor and resets the count of the pulses received from the magnetic sensor.

Abstract: A replaceable unit for an electrophotographic image forming device according to one example embodiment includes an elongated body extending along a lengthwise dimension between a front and a rear of the body. The body has a reservoir for holding toner. The body includes an extension downward from the bottom of the body near the rear of the body. The extension has a downward chute formed therein in fluid communication with the reservoir. A rear face of the extension is unobstructed to receive a bias force in a forward direction toward the front of the body along the lengthwise dimension. An outlet port on the bottom of the extension is in fluid communication with the chute for transferring toner out of the reservoir. The replaceable unit may include a positioning bump on the bottom of the body at a rearmost position on the bottom of the body.
