Abstract

An imaging apparatus having RFID tags associated with wearable components of a system to track the usage and wear levels of the wearable components. The RFID tags can be antennas formed from conductive material impregnated in the wear components such that the RFID tags are worn with the wearing of the wear components. The RFID tags may also be RFID chip tags having memory for storing information, a portion of which is updated in real time. The presence or absence of the impregnated antenna RFID tags or the updated information stored in the chip tags may be used to track usage and wear level of the wear components.

Claims

1. A device to monitor wearing of at least one wearable component of a system, the device comprising:

a radio frequency identification (RFID) tag disposed in or on a component;

a reader communicatively coupled to the RFID tag; and

a controller coupled to the reader to monitor wear of the component based upon communication between the reader and the RFID tag.

2. The device of claim 1, wherein the RFID tag comprises one of an ink tag and a chip tag.

3. The device of claim 1, wherein the RFID tag comprises an antenna formed from a conductive material substantially impregnated in the component.

4. The device of claim 3, wherein the antenna reflects signals transmitted by the reader for reception thereby, the conductive material forming the antenna being impregnated in the component such that the antenna'"'"'s ability to reflect the transmitted signals deteriorates as the component wears from prolonged use.

5. The device of claim 4, wherein the conductive material forming the antenna is impregnated in only a portion of the component.

6. The device of claim 5, further comprising a member for receiving or radiating radio waves, the member being coupled to the reader and disposed in proximity with the RFID tag, wherein movement of the component is detected by the reader using the member

7. The device of claim 3, wherein the conductive material forming the antenna is impregnated at a predetermined depth in the component such that the antenna is unable to reflect the signals transmitted by the reader until the component is worn from use.

8. The device of claim 7, wherein the controller determines that the component or a subcomponent thereof needs replacement based upon detection by the reader of a signal reflected by the antenna.

9. The device of claim 3, wherein the controller determines an amount of wear of the component based upon a signal strength of signals reflected by the antenna.

10. The device of claim 9, wherein the controller detects a wear pattern of the component based upon the signal strength of the signals reflected by the antenna.

11. The device of claim 1, wherein the RFID tag comprises a chip tag having stored therein information, a portion of the stored information being updated in real time during system use.

12. The device of claim 1, wherein the component comprises one of a pick member, a wear strip, and a fuser roller of an image forming device.

13. The device of claim 1, wherein the device comprises at least two RFID tags to monitor wearing of at least two components, each of the at least two RFID tag being disposed in or on a respective one of the at least two components.

14. A system component, comprising:

a radio frequency identification (RFID) tag coupled to or disposed on or in the component, wherein signals transmitted by the RFID tag indicate at least one of the component needing to be replaced and the component needing no immediate replacement.

15. The system component of claim 14, wherein the RFID tag comprises an antenna formed from a conductive material impregnated within a portion of the component.

16. The system component of claim 15, wherein the antenna is formed in the component portion such that wear of the component portion deteriorates the antenna.

17. The system component of claim 15, wherein the antenna is formed in the component portion such that the antenna cannot reflect signals until the component portion is sufficiently worn.

18. The system component of claim 15, wherein the conductive material is impregnated in only a portion of the component portion.

19. The system component of claim 14, wherein the RFID tag comprises an RFID chip tag disposed on or in the component.

20. A system, comprising:

one or more components, each component including an RFID tag;

a reader communicatively coupled to the RFID tag of the one or more components; and

a controller communicatively coupled to the reader for determining an amount of wear of each of the one or more components based upon communication between the RFID tag thereof and the reader.

21. The system of claim 20, wherein the controller determines, for each of the one or more components, whether the component has appreciably worn from use and needs replacement based upon the communication between the RFID tag and the reader.

22. The device of claim 21, wherein the controller determines, for each of the one or more components, whether the component has appreciably worn from use and needs replacement based upon at least one of the RFID tag of the component no longer communicating with the reader, the RFID tag of the component beginning to communicate with the reader, and the RFID tag of the component providing information relating to use of the component stored in memory of the RFID tag.
