Brand new Brother high-yield black toner cartridge for the HL-4150CDN printer. It offers a 6k page yield, ensuring long - lasting use and high - quality prints.

Using this Brother black toner is easy. First, turn off your HL - 4150CDN printer and open the toner compartment. Remove the old cartridge carefully and unpack the new one. Shake the new cartridge gently a few times to distribute the toner evenly. Then, insert it into the compartment until it clicks into place. Close the compartment and turn on your printer. For best results, store the toner cartridge in a cool, dry place away from direct sunlight. If you notice any print quality issues, clean the printer's contacts gently with a dry cloth. And when it's time to replace the cartridge again, follow the same steps.
