Please follow the steps below to replace the toner cartridge:

The Brother machine has separate consumables - the toner cartridge and the drum unit. Verify you replace only the Toner Cartridge and not the Drum Unit. If you want to know their difference, refer to "What is the difference between the toner cartridge and the drum unit?"

NOTE: Illustrations shown below are from a representative product and may differ from your Brother machine.

1. Make sure that the printer is turned on. Open the front cover.
   
2. Take out the drum unit and toner cartridge assembly.
   Hold your Brother machine with one hand and hold the drum unit with the other hand. Then, pull the drum unit toward you and lift it up.
   
   
   • We recommend that you put the drum unit and toner cartridge assembly on a piece of disposable paper or cloth in case you accidentally spill or scatter toner.
   • To prevent damage to the printer from static electricity, DO NOT touch the electrodes shown in the illustration.
    
   
3. Push down the blue lock lever and take the toner cartridge out of the drum unit.
   

    

    

   • DO NOT put a toner cartridge into a fire. It could explode, resulting in injuries.
   • Use neutral detergents when cleaning the printer.
   • DO NOT use cleaning materials that contain ammonia, alcohol, any type of spray, or any type of flammable
     substance to clean the outside or inside of the machine. Doing this may cause a fire or electrical shock.
   • Be careful not to inhale toner.
   • 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 
    
   

    

    

   • Be sure to seal up the toner cartridge tightly in a bag so that toner powder does not spill out of the cartridge.
   • Discard the used toner cartridge according to local regulations, keeping it separate from domestic waste. If you have questions, call your local waste disposal office.
    
4. Unpack the new toner cartridge. Gently shake it from side to side several times to distribute the toner
   evenly inside the cartridge.
   

    

    

   • 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.
    
   
5. Pull off the protective cover.
   
6. Put the new toner cartridge firmly into the drum unit until you hear it lock into place. If you put it in properly, the lock lever will lift automatically.
   
   

   Make sure that you put in the toner cartridge properly or it may separate from the drum unit.

    
   
7. Clean the primary corona wire inside the drum unit by gently sliding the blue tab from right to left and left to right several times.
   
   

   Be sure to return the tab to the home position (1). If you do not, printed pages may have a vertical stripe.

    
   
8. Put the drum unit and toner cartridge assembly back in the printer. Close the front cover.
