State of this machine
Printing is possible, but the remaining toner

The toner cartridge is empty. Printing stops.
About 300 pages can be printed from when the time for replacement is approaching to when the time for
replacement has arrived. (reference value for A4_ISO pattern_simplex printing)
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.)
