Abstract
A sensing system for detecting a full condition within a waste developer system, the sensing system including a developer waste container for receiving and holding waste developer material comprising toner and carrier deposited therein from a developer system; a sensor assembly mounted exterior to the developer waste container, the sensor including a reed switch being responsive to the level of material in the developer waste container when the material in the developer waste container reaches a predetermined level.
Claims9
In a sensing system for detecting a full condition within a waste developer system, said sensing system comprising:
- a developer waste container for receiving and holding waste developer material comprising toner and carrier deposited therein from the waste developer system,
- a sensor assembly mounted exterior to the developer waste container, said sensor assembly including a reed switch being responsive to the level of material in said developer waste container when the developer material in said developer waste container reaches a predetermined level, said sensor assembly further comprises a magnet, adjacent to said reed switch and developer waste container, one pole of said magnet in proximity to the developer material in said developer waste container to operate said reed switch when the developer material reaches said predetermined level, said reed switch has a first and second end, said magnet is positioned so that said first end of the reed switch is midway between the poles of the magnet in which the longitudinal axes of the reed switch and the north-south axis of the magnet are at right angles to each other.
A system for detecting ferrous material in a container comprising:
- a sensor assembly mounted exterior to the container, said sensor assembly including a reed switch being responsive to the level of the ferrous material in said container when the ferrous material reaches a predetermined level, said sensor assembly further comprises a magnet, adjacent to said reed switch and said container, wherein one pole of said magnet is positioned near the ferrous material in said container to operate said reed switch when the ferrous material reaches said predetermined level, said reed switch has a first and second end, said magnet is positioned so that said first end of the reed switch is midway between the poles of the magnet in which the longitudinal axes of the reed switch and the magnet are at right angles to each other.
A device for a machine comprising:
- a sensor assembly having a first mode of operation for sensing an amount of ferrous material in a container of the machine and a second mode of operation for sensing the presence of the container within the machine, said sensor assembly is mounted exterior to the container, said sensor assembly including a reed switch being responsive to the level of the ferrous material in said container when the ferrous material in said container reaches a predetermined level.
