Brand new Brother Mfc - J4320Dw high - yield black ink. With a 550 - page yield, it offers long - lasting printing performance.

Using this Brother Mfc - J4320Dw black ink is easy. First, turn off your printer and open the ink cartridge compartment. Then, gently remove the old cartridge and replace it with this high - yield one. Make sure it's properly seated. When it comes to maintenance, keep the printer in a cool, dry place. Don't expose the ink cartridges to direct sunlight or extreme temperatures. If you're not going to use the printer for a long time, print a test page every few weeks to prevent the ink from drying up. And always follow the printer's user manual for more detailed instructions.
