Note
• 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. (See EU Directive 2002/96/EC and EN 50419 in the Safety
and Legal Booklet.)
• 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 19798. Frequency of
replacement will vary depending on the complexity of printed pages, percentage of coverage
and type of media used.
