Most xerographic copiers and printers use a waste bottle to accumulate waste toner cleaned from a photoreceptor whereupon the bottle must be replaced when full. For man machines, the removal and replacement of a waste toner
minimize service cost, it is often beneficial that a Service Engineer replace the waste bottle at an interim service call, rather than wait for an optical sensor to detect that the bottle is full and initiate an unscheduled service call. It is instrumental then, that a Service Engineer know how much toner is in the bottle each time a machine is serviced. Normally, the waste bottle is opaque and often located in an inaccessible location of the machine so as to prevent visual monitoring. Hence, an alternate technique for sensing the amount of waste toner in the bottle is required. One alternative that has been used involves counting the number of copies since the bottle was last installed. This approach is not only indirect, but also inaccurate due to a wide variation in the amount of waste toner generated per copy. The inaccuracy correspondingly causes frequent bottle replacements and higher service costs.

A new method for determining the amount of waste toner in a waste toner bottle is proposed that consists of counting the number of revolutions of a toner dispenser...
