Refill Kits allow customers to continue using the print cartridges already in their printers, by providing the necessary set of tools to completely fill or top off ink cartridges. Most Refill kits will contain a supplied injection inlet sticker which will attach at the top of the cartridge to help align where the ink injections will be made. Some other kits will use the stabilizing clip to help align the injection points. Once the cartridge is stabilized and set up for refilling, the next step would be to inject the cartridge with the desired ink using a measured syringe or specially designed bottle. After the ink is incorporated into the cartridge, some kits may call for pressurizing the cartridge by injecting air into the top of the cartridge. And the final step to having a quality replacement cartridge would be to dab the ink nozzle located at the bottom of the cartridge with a damp paper towel, cleaning off any excess ink.
