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, as well as notifying it to your authorized
service representative automatically by the remote service.
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 "TONER NOT
RECOGNIZED" appears on the touch panel 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.
Never attempt to incinerate toner cartridges.
Dispose of used toner cartridges and waste toner boxes in accordance with local regulations.
Do not touch the terminal of the toner cartridge.
This may cause the equipment not to recognize the toner cartridge or may
damage the terminal.
Some toner is still left in the toner cartridge while the message "Toner near Empty" is displayed. You do not have to
replace the toner cartridge yet, but if you choose to do so, follow the procedure  P.54 "Replacing a "Near Empty"
toner cartridge".
Open the front cover of the equipment.
