When Message Lamp is Lit/Blinking 79
When a toner cartridge other than the one we recommend is used, neither the cartridge
detecting function nor the toner remaining check function can be utilized. In this case, the
toner lamp blinks even if the toner cartridge is installed in the equipment.
See the following for the difference between when using a TOSHIBA-recommended toner
cartridge and another type:
Recommended toner cartridges
To assure an optimal printing performance, we recommend that you use TOSHIBA toner cartridges.
If you use a TOSHIBA-recommended toner cartridge, you can utilize the following two check functions of
this equipment:
Cartridge detecting function: This function checks if the toner cartridge is correctly installed and notifies
you if it is not.
Toner-remaining check function: This function notifies you when there is little toner remaining in the
cartridge.
Any copying or printing operation is available even if you are using a toner cartridge other than the one
we recommend. In that case, however, the equipment cannot detect whether the toner cartridge is
installed or not and therefore the toner lamp is lit even if the toner cartridge is correctly installed. You can-
not utilize the toner remaining check function either.
If you are using a toner cartridge other than the one we recommend and you feel annoyed by this lighting
lamp, contact your service representative. Your service technician will cancel the cartridge detecting func-
tion set by default. Remember once this function has been cancelled, you will not be able to utilize the two
functions mentioned above even if you change the cartridge to the one we recommend.
