1. To locate the filler hole of the cartridge you must remove the plastic cover. This cover must be remove before refilling it with ink by carefully prying it off with a thin metal blade, such as a thin flathead screwdriver.
Another method is to lay the cartridge on its side, and grasp it firmly then break the seal by striking it with a blunt object.
Important: Make certain that the sensors on the back of the cartridge do not get damaged.
2. Attach the filling needle to the syringe and fill with the proper color of ink.
3. Insert the filling needle into the corresponding hole of the color to be refilled, (see diagram above) and push as far down into the cartridge. Note: You may feel a slight pressure by the sponge inside the cartridge.
4. Inject approximately 7 ml. of ink slowly into cartridge and stop when the ink begins to surface.
Important: The sponge inside is white. And in order to prevent overfilling the chamber, the color of the sponge must remain white. As soon as the ink starts to bubble near the needle then stop injecting, the cartridge is full.
5. Rinse the syringe and needle with water and dry between each color refilling or store for further use.
6. The cover can be remounted securely with a piece of adhesive tape.
Note: Immediately refill any cartridge that has gone empty.
