Using this Brother HL-5140 black toner is easy. First, make sure your printer is turned off. Open the toner compartment and remove the old toner cartridge. Then, take out the new toner from its packaging and gently shake it a few times to distribute the toner evenly. Insert the new cartridge into the compartment until it clicks into place. Close the compartment and turn on your printer. When it comes to maintenance, keep the toner cartridge in a cool, dry place. If you're not using the printer for a long time, it's a good idea to leave the toner in the cartridge to prevent it from drying out. Also, avoid touching the drum inside the cartridge as it can be damaged by fingerprints. That's all you need to know to keep your printing running smoothly.
