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 two 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.
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 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
cartridge check function as we mentioned.
Never attempt to incinerate toner cartridges.
Dispose of used toner cartridges in accordance with local regulations.
 You can replace a toner cartridge while the print function is in operation when "Open the toner cover
Install new toner cartridge" is displayed.
 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.45
"Replacing a "Near Empty" toner cartridge". This procedure is needed to reset the toner counter to
display the next "Toner near Empty" message at the proper time.
Open the toner cover on the front of the equipment.
