Electrical connections for circuit boards on universal toner cartridges
An improved communication method for use in a toner cartridge with two independently-generated electrical signals used to activate a printer. A first connection pad and a second connection pad mounted on a first circuit board to make electrical contact with upper door-mounted electrical contacts that are provided on printers of a particular family of printers. A first connector provides electrical communication between the first end of the conductor and the first circuit board. A second connector provides electrical communication between a second end of said connector and a second circuit board having a second terminal connector secured to said second end of said conductor and a second receiver connector secured to said second circuit board.
1. A toner cartridge adapted to fit within a toner cartridge-receiving cavity of a printer, comprising:
a first electrical contact means adapted to mate with the electrical contacts in a first family of printers; and
a second electrical contact means adapted to mate with the electrical contacts in a second family of printers.
2. The toner cartridge of claim 1 wherein said first and second electrical contact means being in electrical communication.
3. The toner cartridge of claim 1 further comprising an electrical contact pad on said first electrical contact means.
4. The toner cartridge of claim 3 wherein the electrical contact pad is sufficiently large to mate with a first group of printers having an electrical contact in a first position and a second group of printers having an electrical contact in a second position.
5. The toner cartridge of claim 1 wherein the first electrical contact means is formed in a substantially horizontal top wall of the cartridge.
6. The toner cartridge of claim 1 further comprising at least one electrical contact pad on said second electrical contact means.
7. The toner cartridge of claim 6 wherein the electrical contact pad is sufficiently large to mate with a first group of printers having an electrical contact in a first position and a second group of printers having an electrical contact in a second position.
8. The toner cartridge of claim 1 wherein the first electrical contact means is formed in a substantially vertical wall of the cartridge.
9. The toner cartridge of claim 1 wherein the first electrical contact means further comprises a switch.
10. The toner cartridge of claim 9 wherein said switch is a brand selector switch comprising a plurality of discrete settings, wherein each discrete setting identifies the printer's brand.
11. The toner cartridge of claim 9 wherein the switch is chosen from the group consisting of rotary switches, slide switches, jumpers, and button arrays.
12. A toner cartridge adapted to fit within a toner cartridge-receiving cavity of a printer, comprising:
an electrical contact means adapted to engage in electrical communication with the printer when installed in the cartridge-receiving cavity thereof; and
a switch in electrical communication with said electrical contact means;
wherein said switch is a brand selector switch comprising a plurality of discrete settings, and wherein each discrete setting identifies the printer's brand.
13. The toner cartridge of claim 12 further comprising an electrical contact pad, wherein the electrical contact pad is sufficiently large to mate with a first group of printers having an electrical contact in a first position and a second group of printers having an electrical contact in a second position.
14. The toner cartridge of claim 13 wherein the electrical contact means is formed in a substantially horizontal top wall of the cartridge.
15. The toner cartridge of claim 13 wherein the electrical contact means is formed in a substantially vertical wall of the cartridge.
16. The toner cartridge of claim 12 wherein the switch is chosen from the group consisting of rotary switches, slide switches, jumpers, and button arrays.
17. The toner cartridge of claim 12 wherein the electrical contact means is capable of establishing electrical communication with a plurality of printer brands, responsive to the position of said switch.
18. A toner cartridge adapted to fit within a toner cartridge-receiving cavity of a printer, comprising:
a electrical contact means adapted to mate with the electrical contacts in a first family of printers;
a electrical contact pad on said electrical contact means, said electrical contact pad being sufficiently large to mate with a first group of printers having an electrical contact in a first position and a second group of printers having an electrical contact in a second position.
