CAUTION

Wait to unpack the toner cartridge until immediately before you put it in the printer. If toner cartridges are 
left unpacked for a long time the toner life will be shortened.

If an unpacked drum unit is put in direct sunlight or room light, the unit may be damaged.

Put the toner cartridge in the drum unit immediately after you have removed the protective cover. To prevent 
any degradation to the print quality, DO NOT touch the shaded parts shown in the illustrations.

CAUTION

For USA and Canada

Brother strongly recommends that you do not refill the toner cartridge provided with your printer. 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.

CAUTION

For UK and other countries

Brother machines are designed to work with toner of a particular specification and will work to a level of 
optimum performance when used with genuine Brother branded toner cartridges. Brother cannot guarantee 
this optimum performance if toner or toner cartridges of other specifications are used. Brother does not 
therefore recommend the use of cartridges other than genuine Brother branded cartridges with this 
machine.

If damage is caused to the drum unit or other part of this machine as a result of using other manufacturer’s 
products with this machine, any repairs required as a result may not be covered by the warranty.
