How do I add ink to the printer?

1, black ink cartridge, lift the sticker on it and make a hole.

2. Color ink cartridge with three holes after removing the sticker.

3. Enlarge the ink adding hole until the needle tube can be inserted.

4. Add 6-8ML to black and 3-4ML to each color. Please be careful not to cross colors.

5, please grasp the strength when drilling, the hole is not particularly good to drill, but when you really want to drill, don't use too much force.

6, whether drilling or adding ink, please try not to touch the ink cartridge chip and nozzle.
