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?"

Please follow the steps below to replace the toner cartridge:

1. Make sure that the machine is turned on.
   
   
2. Press the front cover release button and then open the front cover.

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

   • We recommend that you place the drum unit and/or the toner cartridge on a clean, flat, level, stable surface with a sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter 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 illustration.
   
   
   
   

   • Be sure to seal up the toner cartridge tightly in a suitable bag so that toner powder does not spill out of the cartridge.
