    • Brother strongly recommends that you DO NOT refill the toner cartridges provided with your machine. We also strongly recommend that you continue to use only Genuine Brother Brand replacement toner cartridges. Use or attempted use of potentially incompatible toner and/or cartridges in the Brother machine may cause damage to the machine and/or may result in unsatisfactory print quality. Our warranty coverage does not apply to any problem that is caused by the use of unauthorized third party toner and/or cartridges. To protect your investment and obtain premium performance from the Brother machine, we strongly recommend the use of Genuine Brother Supplies.
    • We recommend that you place the toner cartridge on a clean, flat surface with a piece of disposable paper underneath it in case you accidentally spill or scatter toner.
    • DO NOT put a toner cartridge into a fire. It could explode, resulting in injuries.
    • Discard the used toner cartridge according to local regulations, keeping it separate from domestic waste. Be sure to seal up the toner cartridge tightly in a suitable bag so that toner powder does not spill out of the cartridge. If you have questions, call your local waste disposal office.
    • Handle the toner cartridges carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
    • Wait to unpack the toner cartridge until immediately before you put it in the machine. If a toner cartridge is left unpacked for a long time, the toner life will be shortened.
    • To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
