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 sensor. The processing circuitry counts the number of the pulses received from the 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 sensor and resets the count of the pulses received from the sensor.
