6. Before you open the new cartridge package shake it four or five times and remove it from the package .
(Don't remove or tear the label on the cartridge otherwise ink will leak out) .
(Don't touch the green chip on the front of the ink cartridge - you could damage the cartridge).

8. Replace any other cartridges that need replacing.
