Abstract
According to aspects of the embodiments, there is provided an apparatus and method to detect when a consumable such as a toner bottle is replaced before end of life (EOL), throwing out toner that could be used for future printing incurs a cost. In metered accounts, the supplier incurs the cost of this waste. This disclosed process proposes monitoring the approximate rate of toner and then calculating the average amount of consumption per bottle since the last time the bottle was detected as empty. This then determines the toner consumption per bottle yield rate. Yield rate (YR) is calculated based on the estimated amount of toner delivered from a known bottle quantity at the point when the current bottle goes empty. The yield rate is displayed as a gauge on the user interface of the printer.
