Abstract

The present disclosure relates to a device and method for removal of image forming deposits between two contacting surfaces in an image forming device or image forming device cartridge. The method includes positioning an insert between the contacting surfaces which insert is capable of removing the deposits when the insert is inserted or removed from the device. The deposits may include those that may ultimately adhere or weld to the surfaces of the device during shipping and/or storage and upon exposure to differential environmental conditions.

Claims (31)

1. A method for removal of an image forming substance deposit in an image forming device containing two opposing surfaces capable of containing said deposit comprising positioning an insert between said surfaces which insert is capable of removing said deposit when said insert is inserted or removed from said device, wherein said insert comprises first and second sections that are folded to form a fold and said fold is inserted between said opposing surfaces.

2. The method of claim 1 wherein said insert comprises a non-woven fabric material.

3. The method of claim 1 wherein said insert comprises a thermally bonded non-woven fabric material.

4. The method of claim 1 wherein said insert comprises a thermally bonded non-woven having a basis weight of about 20-200 grams/square meter.

5. The method of claim 1 wherein said insert contains less than about 5.0% (wt) of compounds having a molecular weight of less than or equal to about 500.

6. The method of claim 1 wherein said insert includes one or more openings to engage a gripping device.

7. The method of claim 6 wherein said gripping device is capable of mechanically engaging with said image forming device.

8. The method of claim 1 wherein said opposing surfaces are located between a roller and a blade member.

9. The method of claim 8 wherein said insert comprises first and second sections that are folded to form a fold and said fold is inserted between said opposing surfaces and said roller includes an exposed surface and one of said first or second sections of said insert covers a portion of said exposed surface.

10. The method of claim 1 wherein said image forming device comprises an image forming device cartridge.

11. A method for removal of an image forming substance deposit in an image forming device containing two opposing surfaces capable of containing said deposit comprising:

operating said device; and

positioning an insert between said opposing surfaces which insert is capable of removing said deposit when said insert is inserted or removed from said device,

wherein said insert contains less than about 5.0% (wt) of compounds having a molecular weight of less than or equal to about 500.

12. The method of claim 11 wherein said insert comprises a non-woven fabric material.

13. The method of claim 11 wherein said insert comprises a thermally bonded non-woven fabric material.

14. The method of claim 11 wherein said insert comprises a thermally bonded non-woven having a basis weight of about 20-200 grams/square meter.

15. The method of claim 11 wherein said image forming device comprises an image forming device cartridge.

16. An image forming device comprising:

two opposing surfaces capable of containing an image forming material deposit; and

an insert positioned between said surfaces wherein said insert comprises a non-woven material containing less than 5.0% (wt.) of compounds having a molecular weight of less than or equal to about 500, wherein said insert is capable of removing said deposit when said insert is inserted or removed from said device.

17. The image forming device of claim 16 wherein said insert comprises a non-woven fabric material having a basis weight of about 20-200 grams/square meter.

18. The image forming device of claim 16 wherein said device is an image forming device cartridge.

19. The image forming device of claim 16 wherein said insert comprises a thermally bonded non-woven fabric material.

20. The image forming device of claim 16 wherein said insert comprises first and second sections that are folded to form a fold and said fold is inserted between said opposing surfaces.

21. The image forming device of claim 16 wherein said insert includes one or more openings to engage a gripping device.

22. The image forming device of claim 21 wherein said gripping device is capable of mechanically engaging with said image forming device.

23. The image forming device of claim 16 wherein said opposing surfaces are located between a roller and a blade member.

24. The image forming device of claim of claim 23 wherein said insert comprises first and second sections that are folded to form a fold and said fold is inserted between said opposing surfaces and said roller includes an exposed surface and one of said first or second sections of said insert covers a portion of said exposed surface.

25. A method for removal of an image forming substance deposit in an image forming device containing two opposing surfaces capable of containing said deposit comprising positioning an insert between said surfaces which insert is capable of removing said deposit when said insert is inserted or removed from said device, wherein said insert contains less than about 5.0% (wt) of compounds having a molecular weight of less than or equal to about 500.

26. A method for removal of an image forming substance deposit in an image forming device containing two opposing surfaces capable of containing said deposit comprising positioning an insert between said surfaces which insert is capable of removing said deposit when said insert is inserted or removed from said device, wherein said insert includes one or more openings to engage a gripping device.
