NOTE
• 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 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.
