Abstract

A portion of a replaceable component of an imaging device is selectively deformed or melted.

Claims

1. A method comprising:

directly and physically contacting a surface of a portion of a replaceable component installed in an imaging device with a surface of a portion of a heated object; and

selectively deforming or melting the portion of the replaceable component with the portion of the heated object directly and physically contacting the surface of the portion of the replaceable component,

wherein the replaceable component remains operable after selectively deforming or melting the portion of the replaceable component.

2. The method of claim 1, wherein selectively deforming or melting the portion of the replaceable component occurs upon occurrence of a predetermined state.

3. The method of claim 2, wherein the predetermined state corresponds to a useful, limited and/or operable lifetime of the replaceable component.

4. The method of claim 2, further comprising sensing the predetermined state before selectively deforming or melting the portion of the replaceable component.

5. The method of claim 2, wherein the predetermined state of the replaceable component corresponds to an initial state prior to initial operation of the replaceable component.

6. The method of claim 2, wherein the predetermined state of the replaceable component corresponds to the replaceable component reaching an end of its warranty period.

7. The method of claim 2, wherein the predetermined state of the replaceable component corresponds to a percentage of a condition that occurs at a predetermined final state of the replaceable component.

8. The method of claim 1, wherein selectively deforming or melting the portion of the replaceable component is in response to instructions from logic located remotely of the imaging device.

9. The method of claim 1, wherein directly contacting the portion of the replaceable component with a heated object comprises forcing a heated plate against the surface of the portion of the replaceable component.

10. The method of claim 1, wherein selectively deforming or melting the portion of the replaceable component includes selectively deforming or melting a body of the replaceable component.

11. The method of claim 1, wherein the heated object is configured to directly and physically contact the replaceable component when the replaceable component is installed in the imaging device.

12. The method of claim 1, wherein selectively deforming or melting the portion of the replaceable component occurs while the replaceable component is installed in the imaging device.

13. A method of operating an imaging device, comprising:

forcibly engaging a surface of a portion of a replaceable component installed in the imaging device into direct physical contact with a surface of a portion of a marker; and

when the replaceable component is at a predetermined state, heating the marker to deform or melt the portion of the replaceable component with the portion of the maker in direct physical contact with the surface of the portion of the replaceable component,

wherein the replaceable component remains operable after deforming or melting the portion of the replaceable component.

14. The method of claim 13, wherein forcibly engaging a surface of a portion of a replaceable component installed in the imaging device into direct physical contact with a surface of a portion of a marker comprises forcibly engaging the surface of the portion of the replaceable component into direct physical contact with a plate.

15. The method of claim 14, wherein heating the marker comprises dissipating electrical power in a resistor thermally coupled to the plate.

16. The method of claim 13, wherein the predetermined state corresponds to an amount of contents within the replaceable component or an amount of wear of the replaceable component or both.

17. The method of claim 13, wherein heating the marker is in response to a signal indicative of the predetermined state.

18. The method of claim 13, wherein heating the marker is triggered by logic located remotely of the imaging device.

19. The method of claim 13, wherein heating the marker to deform or melt the portion of the replaceable component includes heating the marker to deform or melt a body of the replaceable component.

20. The method of claim 13, wherein the marker is configured to directly and physically contact the replaceable component when the replaceable component is installed in the imaging device.

21. The method of claim 13, wherein heating the marker comprises heating the marker while the replaceable component is installed in the imaging device.

22. An imaging device comprising:

at least one marker having a surface configured to directly and physically contact a surface of a portion of a replaceable component installed in the imaging device,

wherein the at least one marker is configured to selectively deform or melt the portion of the replaceable component when the replaceable component is at a predetermined state, when the surface of the at least one marker is in direct physical contact with the surface of the portion of the replaceable component, and when the at least one marker is heated,

wherein the replaceable component remains operable after selectively deforming or melting the portion of the replaceable component.

23. The imaging device of claim 22, wherein a biasing device causes the marker to forcibly engage the surface of the portion of the replaceable component.

24. The imaging device of claim 22, wherein the marker comprises a plate that forcibly engages the surface of the portion of the replaceable component.

25. The imaging device of claim 22, wherein the imaging device comprises local logic configured to control the marker.

26. The imaging device of claim 25 further comprises a sensor coupled to the local logic for sensing when the marker is to deform or melt the portion of the replaceable component.

27. The imaging device of claim 25 wherein the local logic is configured to receive information from remote logic located remotely of the imaging device.

28. The imaging device of claim 22 further comprises a plurality of markers, the markers configured to respectively deform or melt respective portions of the replaceable component when heated and in direct physical contact with the respective portions of the replaceable component.

29. The imaging device of claim 22, wherein the portion of the replaceable component includes a body of the replaceable component.

30. The imaging device of claim 22, wherein the at least one marker is configured to directly and physically contact the replaceable component when the replaceable component is installed in the imaging device.

31. The imaging device of claim 22, wherein the at least one marker is configured to selectively deform or melt the portion of the replaceable component while the replaceable component is installed in the imaging device.
