FAQs & Troubleshooting |
The Brother machine has separate consumables the toner cartridge and the drum unit. Verify you replace only the Toner Cartridge and not the drum unit. If you want to know their difference, refer to "What is the difference between the toner cartridge and the drum unit?"
Do NOT use flammable substances or any type of spray to clean the inside or outside of the machine. Doing this may cause a fire or electrical shock.
Open the front cover of the machine.
Pull out the used toner cartridge.
Take the new toner cartridge out of the box.
Handle the toner cartridge carefully. If toner scatters on your hands or clothes, immediately wipe or wash it off with cold water.
Hold the cartridge level with both hands and gently rock it from side to side three to four times to spread the toner evenly inside the cartridge. Remove the tape labeled REMOVE and the orange protective cover from the new toner cartridge.
Put in the new toner cartridge by positioning it in the guide. Slide it gently into the machine. Do not try to push or lock the new toner cartridge in; it must rest loosely in the guide rails and will automatically be positioned properly when the front cover is closed. Note that each color cartridge is individually keyed to prevent improper installation. Match each cartridge color label to the same color label on the machine.
Close the front cover.
