Methods of increasing printer cartridge compatibility

1. A method for converting a first printer cartridge to a second printer cartridge, each of the first and second printer cartridges comprising a waste hopper, the waste hopper comprising a first side and a second side, the first side comprising a drum gear and a bushing positioned around the drum gear, the first side further comprising a first end plate, the first end plate comprising a plurality of positioning pins, the second side comprising a second end plate, the second end plate comprising a plurality of positioning pins, the method comprising:

a. removing the plurality of positioning pins of the first end plate and the second end plate of the first printer cartridge;

b. determining positions of the positioning pins on the first end plate and the second end plate of the second printer cartridge;

c. providing at least one replacement pin resembling at least one of the positioning pins of the second printer cartridge;

d. attaching a plurality of replacement pins to the first end plate and the second end plate of the first printer cartridge at the positions that were previously determined; and

e. replacing the bushing of the first printer cartridge with a bushing resembling the bushing of the second printer cartridge.

2. The method of claim 1 , wherein the replacement pin is different from the positioning pins of the first cartridge.

3. The method of claim 1 , wherein the replacement pin is a truncated version of at least one of the positioning pins of the first printer cartridge that was removed.

4. The method of claim 1 , wherein the step of removing the plurality of positioning pins of the first end plate and the second end plate of the first printer cartridge comprises removing the first end plate and the second end plate of the first printer cartridge.

5. The method of claim 1 , wherein the step of replacing the bushing of the first printer cartridge further comprises removing the second printer cartridge bushing and using the second printer cartridge bushing.

6. The method of claim 1 , wherein the step of replacing the bushing of the first printer cartridge further comprises determining the dimensions of the bushing of the second printer cartridge and creating a replacement bushing based on the dimensions.

7. A printer cartridge modified to work with a second printer, the printer cartridge originally configured to work with a first printer, the printer cartridge comprising:

a. a first waste hopper side, the first waste hopper side comprising:

i. a drum gear and a drum gear bushing positioned around the drum gear, the drum gear bushing comprising similar dimensions of a drum gear bushing of a second printer cartridge, the second printer cartridge being configured to work with a second printer and not with the first printer;

ii. an end plate comprising a plurality of sides, and

iii. a plurality of positioning pins positioned within the sides of the end plate, the positions of the positioning pins within the sides of the end plate being predetermined from the positions of the positioning pins of a first waste hopper side of the second printer cartridge; and

b. a second waste hopper side, the second waste hopper side comprising:

i. a drum axle and a drum electrical contact connected to the drum axle;

ii. an end plate comprising a plurality of sides; and

iii. a plurality of positioning pins positioned within the sides of the end plate, the positions of the positioning pins within the sides of the end plate being predetermined from the positioning pins of a second waste hopper side of the second printer cartridge.

8. The printer cartridge of claim 7 , wherein at least one of the positioning pins of the first waste hopper side of the first printer cartridge comprises the dimensions of a positioning pin of the first waste hopper side of the second printer cartridge.

9. The printer cartridge of claim 7 , wherein at least one of the positioning pins of the second waste hopper side of the first printer cartridge comprises the dimensions of a positioning pin of the second waste hopper side of the second printer cartridge.

10. The printer cartridge of claim 7 , wherein the drum gear bushing originated from the second printer cartridge.

11. The printer cartridge of claim 7 , wherein the end plate of the first waste hopper side originated from the second printer cartridge.

12. The printer cartridge of claim 11 , wherein the positioning pins of the first waste hopper side are attached to the end plate.

13. The printer cartridge of claim 12 , further comprising an adhesive attached to the end plate at a location opposite where the positioning pins are attached.

14. The printer cartridge of claim 7 , wherein the end plate of the second waste hopper side originated from the second printer cartridge.

15. The printer cartridge of claim 14 , wherein the positioning pins of the second waste hopper side are attached to the end plate.

16. The printer cartridge of claim 15 , further comprising an adhesive attached to the end plate at a location opposite where the positioning pins are attached.

17. A method of converting a first printer cartridge to a second printer cartridge, the second printer cartridge comprising a waste hopper, the second printer cartridge comprising a plurality of positioning pins on both sides of the waste hopper, the method comprising:

a. determining the positions of the positioning pins of the second printer cartridge;

b. providing positioning pins for the first printer cartridge; and

c. attaching the positioning pins to the first printer cartridge based on the previously determined positions.

18. The method of claim 17 , further comprising:

a. attaching the positioning pins to at least one end plate; and

b. attaching the at least one end plate to at least one side of the waste hopper of the first printer cartridge.

19. The method of claim 17 , further comprising:

a. determining the structures of the positioning pins of the second printer cartridge; and

b. providing positioning pins for the first printer cartridge that resemble the predetermined structures of the positioning pins of the second printer cartridge.

20. The method of claim 17 , wherein each of the first and the second printer cartridges comprises a drum gear bushing attached on one of its waste hopper sides, the method further comprising modifying the drum gear bushing of the first printer cartridge to resemble the drum gear bushing of the second printer cartridge.
