ABSTRACT:
An improvement for a container disposed in a printing machine is disclosed. The container is adapted to dispense toner and capable of maintaining a quantity of toner therein. The improvement includes a sensor for sensing that the quantity of toner in the container is less than or equal to a predetermined quantity. The sensor is located in and isolated from the container by an isolating arrangement, the isolating arrangement preventing forces applied to the container from being transmitted to the sensor. In the preferred embodiment, the isolating arrangement includes a mechanism for damping movement of the sensor with respect to the container to decouple substantially the sensor from the container.
