Abstract:
Systems and methods for determining the volume of imaging medium in a cartridge are disclosed. An imaging medium may include a movable housing portion and a device coupled to the movable housing portion. The movable housing portion may include a volume of imaging medium and may be configured to move in response to changes in the volume of imaging medium in the movable housing portion. The device may be configured to project a beam of electromagnetic energy onto a location of a beam-receiving photodetector, the beam-receiving location moving in response to movement of the movable housing portion such that the beam-receiving location is based at least on the volume of imaging medium on the movable housing portion.
