Abstract
An apparatus includes a housing having a reservoir for storing consumable material and an outlet for exiting the consumable material from the reservoir; a rotatable shaft disposed inside the reservoir and positioned along a length of the housing; and one or more magnetic members disposed within the housing and coupled to the shaft so as to rotate therewith. The one or more magnetic members generate a magnetic field and when rotating indicate information about the replaceable unit. The information is based upon the presence or absence of the one or more magnetic members relative to one or more predetermined locations for receiving a magnetic member within the housing.
