摘要：
An imaging device includes a mechanism and method for approximating media count in a media tray by utilizing course granularity levels of media detected in the tray in combination with an actual count of media processed by the imaging device. A preferred method of determining media count in a media holding tray includes detecting a first course granularity level of media in the holding tray, counting a number of individual media removed from the holding tray, detecting a second course granularity level of media in the holding tray and, calculating the number of media remaining in the holding tray based upon at least the second level of media detected and the counted number of individual media removed from the tray.
