Replace Supplies
You must replace supplies when the machine indicates that the life of the supply is over.
Using non-Brother supplies may affect the print quality, hardware performance, and machine reliability. The toner
cartridge and drum unit are two separate supplies. Make sure both are installed as an assembly. The model
name of supplies may vary depending on the country.
NOTE
• Be sure to seal up the used supplies tightly in a bag so that toner powder does not spill out of the
cartridge.
•Visit www.brother.com/original/index.html for instructions on how to return your used supplies to the
Brother collection and recycling program. If you choose not to return your used supply, discard the used
supply according to local regulations, keeping it separate from domestic waste. If you have questions,
contact your local waste disposal office.
• We recommend placing used and new supplies on a piece of paper to prevent accidentally spilling or
scattering the material inside.
• If you use paper that is not a direct equivalent for the recommended print media, the life of supplies and
machine parts may be reduced.
• The projected life for each of the toner cartridges is based on ISO/IEC 19752. Frequency of replacement
will vary depending on the print volume, percentage of coverage, types of media used, and powering
on/off the machine.
• Frequency of replacing supplies except toner cartridges will vary depending on the print volume, types of
media used, and powering on/off the machine.
• Handle the toner cartridge carefully. If toner scatters on your hands or clothes, immediately wipe or wash
it off with cold water.
IMPORTANT
• To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.

Replace the Toner Cartridge
1. Make sure the machine is turned on.
2. Open the front cover.
3. Remove the toner cartridge and drum unit assembly from the machine.
4. Push down the green lock lever and take the toner cartridge out of the drum unit.
5. Unpack the new toner cartridge.
6. Remove the protective cover.
7. Push the new toner cartridge firmly into the drum unit until you hear it lock into place.

Make sure you put the toner cartridge in correctly or it may separate from the drum unit.
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.
9. Install the toner cartridge and drum unit assembly back into the machine.
10. Close the front cover of the machine.
• After replacing a toner cartridge, DO NOT turn off the machine or open the front cover until the
machine's display 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
use of Brother Original Supplies.
