CAUTION
| HOT SURFACEAfter you have just used the machine, some internal parts of the machine will be extremely hot. To prevent injury, when you open the front or back cover (back output tray) of the machine DO NOT touch the shaded parts shown in the illustration. If you do this you may get burned. |

1 | Press the front cover release button and open the front cover. |
2 | Slowly take out the drum unit and toner cartridge assembly.   IMPORTANT • | We recommend that you put the drum unit and toner cartridge assembly on a clean, flat 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 caused by static electricity, DO NOT touch the electrodes shown in the illustration. |
|
3 | Push down the blue lock lever and take the used toner cartridge out of the drum unit.   WARNING | DO NOT put a toner cartridge into a fire. It could explode, resulting in injuries. |
  IMPORTANT • | 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. | • | 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-3235/TN-3285). Brother cannot guarantee this optimum performance if toner or toner cartridge of other specifications are used. Brother does not therefore recommend the use of cartridge other than genuine Brother cartridges with this machine, or the refilling of used cartridge 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 cartridge 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. | • | 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. | • | Be sure to seal up the used toner cartridge tightly in a suitable bag so that toner powder does not spill out of the cartridge. |
