190 Replacing Toner Cartridge
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, as well as notifying it to your service representative automatically by the remote service.
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 an error message “Toner not recognized” appears on the LCD screen, even
if the toner cartridge is correctly installed. You cannot utilize the toner remaining check function and the
remote service function notifying your service representative automatically either.
If you are using a toner cartridge other than the one we recommend and you feel annoyed by this mes-
sage, contact your service representative. Your service technician will cancel the cartridge detecting func-
tion set by default. Remember once this function has been canceled, you will not be able to utilize the two
functions mentioned above even if you change the cartridge to the one we recommend.
