Abstract
Estimating toner levels. A method embodiment includes maintaining a running pulse width count, sensing a toner level, and comparing the running pulse width count with an expected pulse width count to estimate a toner level. If the estimated toner level deviates from the sensed toner level, the running pulse width count and the sensed toner level are used to estimate the remaining toner level.
