Routine Maintenance
NOTE
• Go to http://www.brother.com/original/index.html for instructions on how to return the used toner cartridge
to the brother collection program. If you choose not to return your used toner cartridge, please discard the
used toner cartridge according to local regulations, keeping it separate from domestic waste. If you have
questions, call your local waste disposal office.
• We recommend placing used consumable items 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 paper, the life of consumable items
and machine parts may be reduced.
• The projected life for each of the toner cartridges is based on ISO/ICE 19798. 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 replacement consumables except toner cartridges will vary depending on the print volume,
types of media used, and powering on/off the machine.
