InkTec inkjet cartridge refill kits allow you to refill your existing empty ink cartridge. Why buy a new or remanufactured ink cartridge when you can refill the cartridge you have for much less money? Each kit includes the ink, tools and instructions to refill your empty inkjet cartridge and get printing again quickly. It is always a good idea to refill cartridges that have just ran out of ink. You also shouldn't try to keep printing on an empty cartridge as it will burn out of the printheads on your ink cartridge. All inkjet cartridge print quality will eventually fade but by keeping your cartridge full of ink and printing regularly you should be able to get a few cycles with one cartridge before buying a new or remanufactured ink cartridge.
