<Life of toner cartridge>
The life of the toner cartridge varies according to the average number of print pages per job.
(See the table below.) The number of printable pages is larger when making continuous prints
in one job because deterioration of the develop roller is low.

The develop roller also rotates for the warm-up operation, color registration adjustment
operation, and developing bias adjustment operation when the power is turned ON and when
the cover is opened or closed. Therefore, when these operations are frequently performed,
the life of toner cartridges is shortened. (The table below shows the worst case in which the
warm-up operation, color registration adjustment, and developing bias adjustment are
performed when the power is turned ON.)

Memo:
- This product prohibits the print operation while any of the toner cartridges is not mounted
or when "Replace Toner" is displayed. In other words, neither monochrome printing
without a color toner cartridge nor color printing without a black toner cartridge is
available.
- This product does not have a function to identify colors of the color toner cartridges.
