TONER LEVEL SENSING FOR A REPLACEABLE UNIT OF AN IMAGE FORMING DEVICE
摘要
A method for programming memory of a replaceable unit of an electrophotographic image forming device according to one example embodiment includes determining an amount of toner in a reservoir of the replaceable unit. The amount of toner determined is converted to an estimate of an amount of rotation of a shaft that will be sensed before the reservoir of the replaceable unit runs out of usable toner. The estimate of the amount of rotation of the shaft that will be sensed before the reservoir of the replaceable unit runs out of usable toner is stored in the memory of the replaceable unit.
