IMPORTANT
• We recommend that you place the drum
unit and toner cartridge assembly 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.
• 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.
• Go to
 
for instructions on how to return your used 
consumable items to the Brother 
collection program. If you choose not to 
return your used consumable, please 
discard the used consumable according to 
local regulations, keeping it separate from 
domestic waste. If you have questions, 
call your local waste disposal office.
e
Clean the primary corona wire inside the 
drum unit by gently sliding the green tab 
from left to right and right to left several 
times.

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