Replacing the consumable items A
The machine will indicate when it is time to replace the consumable items. (See Replacing the
toner cartridge on page 57 and Replacing the drum unit on page 63.)
Note
• Go to http://www.brother.com/original/index.html 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.
• 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 of the toner cartridges is based on ISO/IEC 19752. Frequency of
replacement will vary depending on the complexity of printed pages, percentage of coverage
and type of media used.
