Abstract

The present invention also includes a method of remanufacturing a printer cartridge, the printer cartridge comprising printer cartridge components fastened together by a pin, the method comprising the steps of providing a device, the device comprising a shaft configured to apply pressure to the pin; a drive means for driving the shaft against the pin; and applying pressure to the pin using the device.

Claims (29)

1. A device for remanufacturing a printer cartridge, the printer cartridge comprising at least two printer cartridge components attached together by a pin, the device comprising:

a. a shaft configured to apply pressure to the pin;

b. a frame connected to the shaft, the frame configured to provide support to the shaft;

c. a cartridge mount connected to the frame, the cartridge mount configured to support a cartridge portion when the shaft applies pressure to the pin, and further wherein the cartridge mount comprises a plurality of grooves, each of the plurality of grooves comprising a distinct shape to accommodate a plurality of printer cartridge components.

2. The device of claim 1 , further comprising a base connected to the frame, the base comprising a substantially flat surface, the base configured to allow the device to be substantially self-supporting.

3. The device of claim 1 , wherein the cartridge mount comprises at least one groove, the groove being shaped to accommodate a plastic drum cap.

4. The device of claim 1 , wherein the cartridge mount is moveably attached to the frame to position a groove selected from the plurality of grooves adjacent to the shaft.

5. The device of claim 1 , further comprising a clamp attached to the shaft, the clamp configured to move the shaft to apply pressure to the pin.

6. The device of claim 1 , further comprising a pin guard for protecting the pin.

7. A device for remanufacturing a printer cartridge, the printer cartridge comprising printer cartridge components joined by a pin, the device comprising:

a. a shaft means for pressing on the pin;

b. a support means for supporting the shaft means, the support means being connected to the shaft means; and,

c. a drive means for driving the shaft against the pin, the drive means being connected to the support means, wherein the support means comprises a wire and the drive means comprises a set of gears configured to wind and unwind the wire.

8. The device of claim 7 , wherein the drive means is configured to rotate.

9. The device of claim 7 , wherein the drive means is configured to move linearly.

10. The device of claim 7 , further comprising a cartridge portion support means for supporting a printer cartridge portion, the cartridge portion support means being attached to the support means.

11. The device of claim 7 , further comprising a base means for allowing the support means to stand on its own, the base means being connected to the support means.

12. A method of remanufacturing a printer cartridge, the printer cartridge comprising printer cartridge components fastened together by a pin, the method comprising the steps of:

a. providing a device, the device comprising:

i. a shaft configured to apply pressure to the pin;

ii. a support means for supporting the shaft, the support means being connected to the shaft; and,

a drive means for driving the shaft against the pin, the drive means being connected to the support means, and wherein the support means comprises a wire and the drive means comprises a set of gears configured to wind and unwind the wire; and,

b. applying pressure to the pin using the device.

13. The method of claim 12 , wherein the printer cartridge comprises a drum cap attached to a drum axle by a pin, the method further comprising detaching the pin from the drum cap.

14. The method of claim 12 , wherein the printer cartridge comprises a drum, the drum comprising a drum cap attached to a drum axle by a pin, the method further comprising inserting the pin through the drum cap and the drum axle to fasten the drum to the drum axle.

15. The method of claim 12 , wherein the printer cartridge comprises a drive element configured to attach a drum axle to the printer, the drive element being attached to the drum axle by a pin, the method further comprising detaching the pin from the drive element and the drum axle.

16. The method of claim 12 , wherein the printer cartridge comprises a drive element configured to attach a drum axle to the printer, the method further comprising inserting the pin through the drive element and the drum axle.

17. The method of claim 12 , further comprising supporting the device with a base to allow the device to stand on a surface substantially independently.

18. The method of claim 12 , further comprising supporting a portion of the printer cartridge while the pressure is being applied on the pin.
