4. The printer cartridge seal applicator of claim 2 , wherein the handle may be used to position the concave side of the applicator body adjacent to the toner supply roller and position the applicator portion in between the toner supply roller and a printer cartridge surface defining a toner opening port.
5. The printer cartridge seal applicator of claim 1 , wherein the applicator portion comprises a plurality of chamfers, the plurality of chamfers defining a notch substantially in between the plurality of chamfers, the notch being configured to accommodate the printer cartridge seal pull strip.
6. A device for promoting adhesion of a printer cartridge seal to a printer cartridge, the device comprising:
an applicator means for applying pressure to the printer cartridge seal, the applicator means defining a notch configured to accommodate a pull strip of the printer cartridge seal; and,
a handle means for positioning the applicator means in between a toner supply roller and a printer cartridge portion defining a toner opening port, the handle means connected to the applicator means.
7. The device of claim 6 , further comprising a body means for supporting the handle means, the body means being connected to the handle means on one end and the applicator means on the other end.
8. The device of claim 7 , wherein the body means is a curved body, the curved body comprising a concave side and a convex side, the concave side being configured to accommodate a toner supply roller adjacent to it.
9. The device of claim 6 , wherein the applicator means comprises a plurality of chamfers, the plurality of chamfers defining a notch in between the plurality of chamfers, the notch configured to accommodate the pull strip of the printer cartridge seal.
10. The device of claim 9 , wherein each of the plurality of chamfers comprises a substantially flat surface, the substantially flat surface configured to press the printer cartridge seal against a printer cartridge surface defining a toner opening port.
11. The device of claim 6 , wherein the applicator means comprises a substantially flat surface configured to press on the printer cartridge seal.
12. An assembly for promoting adhesion of a printer cartridge seal to a printer cartridge portion that defines a toner opening port, the toner opening port being accessible through a toner exit port, the assembly comprising:
a fixture configured to support a printer cartridge, the fixture comprising a plurality of walls configured to minimize movement of the printer cartridge;
a first printer cartridge seal applicator comprising:
a notched applicator portion configured to accommodate a printer cartridge seal pull strip;
a first printer cartridge seal applicator body connected to the notched applicator portion; and,
a first printer cartridge seal applicator handle connected to the first printer cartridge seal applicator body;
a second printer cartridge seal applicator comprising:
a flat applicator portion configured to apply pressure on the printer cartridge seal;
a second printer cartridge seal applicator body connected to the flat applicator portion; and,
a second printer cartridge seal applicator handle connected to the second printer cartridge seal applicator body; and,
a seal insertion tool for inserting the printer cartridge seal through the toner exit port.
13. A method of promoting adhesion of a printer cartridge seal to a printer cartridge, the method comprising:
providing a printer cartridge seal applicator comprising:
an applicator portion configured to apply pressure on the printer cartridge seal, the applicator portion defining a notch configured to accommodate a pull strip of the printer cartridge seal;
an applicator body connected to the applicator portion; and,
a handle connected to the applicator body;
positioning the printer cartridge seal applicator in between a toner supply roller and a printer cartridge surface defining a toner opening port; and,
using the applicator portion to press the printer cartridge seal against the printer cartridge surface defining the toner opening port.
14. The method of claim 13 , further comprising sliding the printer cartridge seal applicator on the printer cartridge seal attached to the printer cartridge surface defining the toner opening port.
15. The method of claim 13 , wherein the printer cartridge seal applicator comprises a curved body, the curved body comprising a concave side, the method further comprising positioning the concave side adjacent to the toner supply roller.
16. The method of claim 13 , wherein the printer cartridge seal applicator comprises a plurality of chamfers, the plurality of chamfers defining a notch, the method further comprising positioning the pull strip of the printer cartridge seal within the notch.
17. The method of claim 13 , wherein the applicator portion comprises a seal contact bottom surface configured to press the printer cartridge seal, the seal contact bottom surface defining a notch, the method further comprising positioning the pull strip of the printer cartridge seal within the notch.
18. A method of promoting adhesion of a printer cartridge seal to a printer cartridge, the method comprising:
providing an assembly for promoting adhesion of a printer cartridge seal to a printer cartridge, the assembly comprising:
a fixture configured to support a printer cartridge;
a first printer cartridge seal applicator having a notched applicator portion;
