8. Clean the 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). The arrow on the tab must be aligned with the arrow on
the drum unit. If it is not, printed pages may have a vertical stripe.

• Do not turn off the machine or open the front cover until the machine returns to Ready Mode.
• The toner cartridge that comes with your Brother machine is a Inbox toner cartridge.
• It is a good idea to keep a new toner cartridge ready for use when you see the Toner Low warning.
• To ensure high quality printing, we recommend using only Brother Original toner cartridges. When you
want to buy toner cartridges, contact Brother Dealer.
• DO NOT unpack the new toner cartridge until you are ready to install it.
• If a toner cartridge is left unpacked for a long time, the toner life will be shortened.
• Brother strongly recommends you DO NOT refill the toner cartridge provided with your machine. We
also strongly recommend you continue to use only Brother Original replacement toner cartridges. Use
or attempted use of third party toner and/or cartridges in the Brother machine may cause damage to the
machine and/or may result in unsatisfactory print quality. Our limited warranty coverage does not apply
to any problem that is caused by the use of third party toner and/or cartridges. To protect your
investment and obtain premium performance from the Brother machine, we strongly recommend the
