IMPORTANT
• DO NOT unpack the new toner cartridge until you are ready to install it. If a toner cartridge is left unpacked
for a long time, the toner life will be shortened.
• If an unpacked drum unit is exposed to direct sunlight (or room light for long periods of time), the unit may
be damaged.
• Brother strongly recommends that you DO NOT refill the toner cartridge 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 limited 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.
• Put the toner cartridge in the drum unit immediately after you have removed the protective cover. To
prevent degradation to the print quality, DO NOT touch the shaded parts shown in the illustration.
