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 53 and Replacing the drum unit on page 59.)
Note
• Discard 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.
