Systems and methods for remanufacturing imaging components
Systems and methods of remanufacturing an imaging cartridge including the replacement an organic photo conductor (OPC) drum in the imaging cartridge having end caps which are fixedly secured to the waste bin or other portion of the toner cartridge. In one aspect, the method involves removing the existing OPC drum without detaching the end caps and installing a replacement OPC drum without disturbing the end caps.
1. A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising an organic photo conductor (OPC) retaining member including an opening;
providing a replacement OPC drum including an internal retaining member;
placing the OPC drum proximate the OPC retaining member;
inserting an external hub into said opening of the OPC retaining member; and
attaching the external hub to the internal retaining member.
2. The method of claim 1 wherein the internal retaining member partially extends from the interior of the OPC drum.
3. The method of claim 1 wherein the external hub comprises a drive gear.
4. The method of claim 1 wherein inserting the external hub is performed before placing the OPC drum.
5. The method of claim 1 wherein the OPC retaining member includes a flange which blocks access to the opening of the OPC retaining member, the method further comprising, before inserting:
removing at least a portion of the flange.
6. The method of claim 1 wherein the external hub comprises a tri-lobe gear.
7. The method of claim 1 wherein a front surface of the internal retaining member is substantially flat.
8. The method of claim 1 wherein the internal retaining member includes an engagement bore.
9. The method of claim 8 wherein the external hub includes an opening for alignment with the engagement bore.
10. The method of claim 9 wherein attaching the external hub to the internal retaining member comprises inserting a cylindrical member into the opening and the engagement bore.
11. The method of claim 10 wherein the cylindrical member comprises a screw.
12. A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising an organic photo conductor (OPC) retaining member including an opening;
providing a replacement OPC drum;
placing the OPC drum proximate the OPC retaining member; and
inserting at least a portion of a shaft through said opening of the OPC retaining member and at least partially into the OPC drum.
13. The method of claim 12 wherein one portion of the shaft comprises a hub sized to rotatably engage the opening of the OPC retaining member.
14. A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising an organic photo conductor (OPC) retaining member including an opening;
providing a replacement OPC drum;
placing the OPC drum proximate the OPC retaining member, and
inserting at least a portion of a hub through said opening of the OPC retaining member and at least partially into the OPC drum.
15. A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising an organic photo conductor (OPC) retaining member including an opening;
providing a replacement OPC drum including a first portion of a hub;
placing the OPC drum proximate the OPC retaining member;
inserting a second portion of the hub into said opening of the OPC retaining member; and
attaching the first portion of the hub to the second portion of the hub.
16. The method of claim 15 wherein the second portion of the hub comprises a gear.
17. The method of claim 16 wherein the gear comprises a tri-lobe gear.
18. The method of claim 15 wherein the first portion of the hub partially extends from the interior of the OPC drum.
19. The method of claim 15 wherein inserting the second portion of the hub is performed before placing the OPC drum.
20. The method of claim 15 wherein a front surface of the first portion of the hub is substantially flat.
21. The method of claim 15 wherein the first portion of the hub includes an engagement bore.
22. The method of claim 21 wherein the second portion of the hub includes an opening for alignment with the engagement bore.
23. The method of claim 22 wherein attaching the second portion of the hub to the first portion of the hub comprises inserting a cylindrical member into the opening and the engagement bore.
24. The method of claim 23 wherein the cylindrical member comprises a screw.
25. A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising first and second organic photo conductor (OPC) retaining members, each OPC retaining member including an opening;
providing a replacement OPC drum assembly comprising an OPC drum and first and second hubs, said OPC drum assembly being at least partially disassembled;
placing the OPC drum between the first and second OPC retaining members; and
assembling the partially disassembled OPC drum assembly by attaching the first hub to the OPC drum.
26. The method of claim 25 wherein the first hub comprises first and second portions, said the first portion of the hub attached to the OPC drum and said second portion of the hub not attached to the OPC drum, and wherein the step of assembling comprises attaching the second portion of the hub to the first portion of the hub.
