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 machines are designed to work with toner of a particular specification and will work to a level of
optimum performance when used with Brother Original 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 Brother Original cartridges with this machine, or the
refilling of empty cartridges with toner from other sources. If damage is caused to the drum unit or other
part of this machine as a result of the use of toner or toner cartridges other than Brother Original products
due to the incompatibility or lack of suitability of those products with this machine, any repairs required as
a result may not be covered by the warranty.
