• 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/IEC 19752. Frequency of
replacement will vary depending on the complexity of printed pages, percentage of coverage
and type of media used.
