 Recommended toner cartridges
To assure optimal printing performance, we recommend that you use only genuine TOSHIBA toner cartridges. 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.
Image quality optimization function: This function controls image quality according to the characteristics 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 "ERROR: TONER" appears
on the LCD screen and printing may not be performed. You may also not be able to utilize the image quality optimization
function and the toner remaining check function.
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.
