System and method for refurbishing print cartridges and print cartridge toner blades
View Patent ↗A refurbished toner blade for a toner cartridge and a method for refurbishing a toner blade for a toner cartridge are provided. The refurbished toner blade includes a fixed portion configured for attachment to a portion of a toner cartridge, a depending portion extending away from the fixed portion, and a permanent deflection that is formed during refurbishment of the toner blade and that extends between the fixed portion and the depending portion. The refurbished toner blade is formed from a used toner blade in which the depending portion has obtained a permanent deformation in a first direction after an initial period of use. The permanent deflection deflects the depending portion in a second direction opposite the first direction.

6. The method of claim 5 , wherein the deflecting die is engaged with the toner blade at a location between the fixed portion and the depending portion.
7. The method of claim 5 , wherein forming the permanent deflection further includes moving the deflecting die along a length of the toner blade.
8. The method of claim 1 , wherein forming the permanent deflection includes forming the permanent deflection substantially adjacent to the fixed portion.
9. The method of claim 1 , wherein obtaining the used toner blade includes obtaining a used developer roller sealing blade.
10. The method of claim 1 , wherein obtaining the used toner blade includes obtaining a used toner cartridge to which the toner blade is attached.
11. A refurbished resilient toner blade for a toner cartridge, the toner blade being substantially planar when new and becoming permanently deformed in a first direction after an initial period of use, the refurbished toner blade comprising:
a fixed portion configured for attachment to a portion of a toner cartridge;
a depending portion extending away from the fixed portion; and,
a permanent deflection comprising a crease extending along a length of the toner blade, the permanent deflection formed during refurbishment of the toner blade, the permanent deflection extending between the fixed portion and the depending portion, and deflecting the depending portion in a second direction opposite the first direction.
12. The toner blade of claim 11 , wherein the toner blade is formed of polyester film.
13. The toner blade of claim 11 , wherein the toner blade comprises a developer roller sealing blade.
14. The toner blade of claim 11 , wherein the permanent deflection is substantially adjacent to the fixed portion.
15. A refurbished toner cartridge comprising:
a toner reservoir portion including a body, the body defining a relatively flat shelf portion;
a toner adder roller rotatably supported by the body; and
a developer roller sealing blade including a fixed portion attached to the shelf portion, a depending portion extending away from the fixed portion and having a permanent deformation in a first direction as a result of an initial period of use, and a permanent deflection formed between the fixed portion and the depending portion, wherein the permanent deflection deflects the depending portion in a second direction opposite the first direction.
16. The refurbished toner cartridge of claim 15 , wherein the permanent deflection comprises a crease extending along a length of the developer roller sealing blade.
17. The refurbished toner cartridge of claim 15 , wherein the toner blade is formed of polyester film.
18. A method of refurbishing a used toner blade for a toner cartridge, the method comprising:
obtaining a used toner blade including a fixed portion configured for attachment to a portion of the toner cartridge, and a depending portion extending away from the fixed portion, the depending portion of the used toner blade having a permanent deformation in a first direction as a result of an initial period of use; and,
forming a permanent deflection between the fixed portion and the depending portion to permanently deflect the depending portion in a second direction opposite the first direction, wherein forming the permanent deflection includes engaging a deflecting die with the toner blade.
19. The method of claim 18 , further comprising fixturing the toner blade.
20. The method of claim 19 , wherein the fixed portion of the toner blade is attached to the portion of the toner cartridge, and wherein fixturing the toner blade includes fixturing the portion of the toner cartridge.
21. The method of claim 18 , wherein forming the permanent deflection includes applying localized pressure to the toner blade.
22. The method of claim 18 , wherein the deflecting die is engaged with the toner blade at a location between the fixed portion and the depending portion.
23. The method of claim 18 , wherein forming the permanent deflection further includes moving the deflecting die along a length of the toner blade.
24. The method of claim 18 , wherein forming the permanent deflection includes forming the permanent deflection substantially adjacent to the fixed portion.
25. The method of claim 18 , wherein obtaining the used toner blade includes obtaining a used developer roller sealing blade.
26. The method of claim 18 , wherein obtaining the used toner blade includes obtaining a used toner cartridge to which the toner blade is attached.
27. A method of refurbishing a used toner blade for a toner cartridge, the method comprising:
obtaining a used developer roller sealing blade including a fixed portion configured for attachment to a portion of the toner cartridge, and a depending portion extending away from the fixed portion, the depending portion of the used developer roller sealing blade having a permanent deformation in a first direction as a result of an initial period of use; and,
forming a permanent deflection between the fixed portion and the depending portion to permanently deflect the depending portion in a second direction opposite the first direction.
28. The method of claim 27 , further comprising fixturing the used developer roller sealing blade.
29. The method of claim 28 , wherein the fixed portion of the used developer roller sealing blade is attached to the portion of the toner cartridge, and wherein fixturing the used developer roller sealing blade includes fixturing the portion of the toner cartridge.
