f Unpack the new toner cartridge. Gently shake it from side to side several times to distribute the toner evenly inside the cartridge.

IMPORTANT

Unpack the toner cartridge just before you put it in the machine. If a toner cartridge is 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.

CAUTION

HOT SURFACE

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.

Troubleshooting and routine maintenance

IMPORTANT

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 toner cartridges (TN-240BK/TN-240C/TN-240M/TN-240Y). Brother cannot guarantee this optimum C performance if toner or toner cartridges of other specifications are used. Brother does

not therefore recommend the use of cartridges other than genuine Brother 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 genuine Brother 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.
