Using this Brother Mfc - J5330Dw high - yield black ink is easy. First, make sure your printer is turned off. Open the printer's ink cartridge compartment, and carefully remove the old cartridge. Then, take out the new black ink cartridge from its packaging and gently insert it into the correct slot. Close the compartment. When you turn on the printer, it will recognize the new cartridge. Remember to keep the ink cartridges in a cool, dry place. Avoid exposing them to direct sunlight. If you're not going to use the printer for a long time, it's a good idea to run a printhead cleaning cycle every few weeks to prevent the ink from drying up in the nozzles. Also, don't touch the metal contacts on the ink cartridge as it may cause printing issues.
