ABSTRACT:
Systems and methods are described hereinto to provide a notification when a predetermined event occurs that is related to a consumable. A print engine outputs hard copies based on electronically received data. One or more toner cartridges that are utilized by the print engine to place toner onto a hard copy substrate. A meter monitors and provides a level of remaining toner for each of the one or more cartridges. A yield component receives level data from each meter to compare to an expected yield and an expected grams per impression, wherein if the expected yield and/or the expected grams per impression are outside of a predetermined threshold, a signal is output.
