Abstract
A method implemented in an imaging device senses the remaining life of a drum maintenance system in the imaging device. The method includes detecting a buoyant member, which is pivotably coupled to a proboscis extending from an end cap of a reservoir in a reservoir of the DMU, reaching a predetermined position in the reservoir and then updating an estimate of the remaining release agent in the reservoir with reference to a total media area and total inked area.
