ABSTRACT:
The invention relates to an improved apparatus and method of refilling an ink jet cartridge used with printers. The kit includes a plug pulling tool, and an amount of ink contained in a syringe-plunger assembly with a cap, The plug pulling tool allows removing a plug from a cartridge without damage, so that the plug can be replaced into the cartridge after being refilled. The syringe-plunger assembly allows the user to seal the nozzle of the syringe tight against the hole in the cartridge, in order to fill the cartridge with ink as well as to remove unwanted air from inside the cartridge. The invention eliminates the need of having to reseal the cartridge by alternate means, allows venting of the cartridge reservoir during the refill process, and significantly increases the efficiency and cleanness of refilling an ink jet cartridge.
