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.
This table lists the messages to replace supplies when they reach their end of life. To avoid any inconvenience,
you may want to buy spare supplies to keep as replacements before the machine stops printing.

NOTE
• Be sure to seal up the used supplies tightly in a bag so that toner powder does not spill out of the
cartridge.
• Discard used consumable items according to local regulations, keeping it separate from domestic waste.
If you have questions, call your local waste disposal office. Be sure to reseal the consumable items tightly
so that the material inside does not spill.
• We recommend placing used 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.
• To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
