Xerox Phaser 6130 Printer Cartridge Chip Reset Tool
This is a tool for resetting the chip that is included in the Xerox Phaser 6130 Printer Cartridges. Since Xerox wants you to buy a new toner cartridges even if you are able to refill them, they included a little EEPROM microchip to prevent self refilling.
Now you can reset this little microchip inside the cartridge yourself.
Warning: I think using this will definitely void the warranty!
