Recommended toner cartridges
To assure optimal printing performance, we recommend that you use only genuine TOSHIBA toner car-
tridges. If you use a TOSHIBA-recommended toner cartridge, you can utilize the following three 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 authorized service representative automatically by the remote ser-
vice.
Image quality optimization function: This function controls image quality according to the characteris-
tics of the toner to be used and enables you to print images of an optimal quality.
If you are using a toner cartridge other than the one we recommend, the equipment may not be able to
detect whether it is installed or not. Therefore, even if the toner cartridge is correctly installed, the error
message “Toner not recognized” appears on the LCD screen and printing may not be performed. You
may also not be able to utilize the image quality optimization function, the toner remaining check function
and the remote service function notifying your authorized service representative automatically.
If you are using a toner cartridge other than the one we recommend, toner is not recognized. If this is a
problem for you, please contact your service representative. Remember you will not be able to utilize the
Toner remaining check function and Image quality optimization function as we mentioned.
