Abstract
A toner dispenser with on-board intelligence. The toner dispenser includes a reservoir of toner material and memory that stores the characteristics and amount of that toner material contained within. A coil resides inside the reservoir to allow the system into which the dispenser is inserted to vibrate the coil. This accomplishes both a churning of the toner, and the back-EMF of the coil can be measured to calculate the amount of toner remaining. The toner dispenser has communications capability that allows it to send the information contained therein to a system processor of the system into which it is inserted.
