clean, flat, level, stable surface with a 
sheet of disposable paper or cloth 
underneath it in case you accidentally spill 
or scatter toner.
• To prevent damage to the machine from  static electricity, DO NOT touch the 
electrodes shown in the illustration.
 
• Handle the toner cartridge carefully. If toner scatters on your hands or clothes, 
wipe or wash it off with cold water at once.
• To avoid print quality problems, DO NOT  touch the shaded parts shown in the 
illustrations.
 
   
 
Note
• Be sure to seal up the toner cartridge 
tightly in a suitable bag so that toner 
powder does not spill out of the cartridge.
• Discard used consumable items  according to local regulations. If you 
choose not to return your used 
consumable, please discard the used

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.

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-230BK/TN-230C/TN-230M/TN-230Y). 
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 
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.
