A method of estimating a quantity of toner remaining in a toner cartridge includes using an adaptive term, a value of which is adjusted based on actual printer toner usage. A printer configured to produce an estimate of an amount of toner remaining in a toner cartridge installed in that printer includes a toner remaining algorithm; and an adaptive term, a value of which is adjusted based on actual printer toner usage rate. The algorithm uses the adaptive term to produce the estimate of an amount of toner remaining in the toner cartridge.
