The following are maintenance messages that appear alternately with the Ready message on the upper row
of the LCD when the printer is in the Ready state. These messages advise you that you will need to replace
each of the consumable items as soon as possible, since the consumable item’s end of life has been reached.
The printer will continue printing when any of these messages appear on the LCD.
1
When printing A4 or Letter size paper. The actual number of printed pages will vary depending on the print jobs and paper you use.
2
at 5% print coverage for CMYK each (A4 or Letter size).
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 printer parts may be reduced.
• The projected life for each of toner cartridges and a waste toner box is based on an average of 5%
coverage of the printable area using any color toner cartridge. Frequency of replacement will vary
depending on the complexity of printed pages, percentage of coverage and type of media used.
