An auger type dispenser for dispensing toner from a toner sump in a xerographic copier can be utilized as a gauge to monitor quantities of toner leaving the sump. Where the quantity of toner leaving the sump is being replaced or replenished by toner from a toner bottle, then by counting the auger revolutions and knowing the capacity of the sump as well as the volume of toner displaced by the auger, the amount of toner left in the bottle can be calculated. This amount of toner left in the bottle can be tracked by a software program, and displayed on a user interface of the copier for the operator's information.
