How to identify toner cartridges
There are the following types of toner cartridges. You can identify by the letters printed on the toner cartridge.
- ST: Starter toner cartridge (which was installed when you purchased the machine.）
- 6K: Toner cartridge
- AK: Toner cartridge (for B842 only)
The number of printable sheets varies with the type of toner cartridge.

Replacement cycle of the toner cartridge
When the time for replacement is approaching or has arrived, the following message appears on the display.
When the time for replacement is approaching | → | When the time for replacement has arrived | |
|---|---|---|---|
Displayed message | Toner Low. | → | Install Toner. Replace With A New Toner Cartridge. |
Response to the message | Please prepare a new toner cartridge. | → | Replace the toner cartridge with a new one. |

- Printing quality will decline after the toner cartridge stays unpacked for one year or longer. Therefore, prepare a new toner cartridge.
- Use genuine OKI consumables for optimum performance.
- Failures caused by using non-genuine consumables may void the warranty or maintenance contract. (The use of non-genuine consumables will not necessarily cause failures, but please fully take notice of such usage.)
- Replace the toner cartridge immediately when a message indicating replacement of the toner cartridge is displayed and printing has stopped.
If you repeatedly open and close the front cover so that you can continue printing temporarily, a failure may be caused or the print quality may be degraded.
In addition, after a certain period of time, printing will be disabled even if you open and close the front cover. (The printable period of time varies with the usage condition.)
