5. Service call lamp
This is lit or blinks when the support of your service technician is needed. Contact your ser-
vice representative.
When the key of the digital keys and the [CLEAR/STOP] button are pressed simulta-
neously, an error code (consisting of a letter of the alphabet and numbers) appears on the LED
display. Contact your service representative with this code.
Never attempt to repair, disassemble or modify the equipment by yourself.
This could cause an electric shock, a fire or serious injury.
Contact your service representative when the equipment is in an abnormal condition or any mal-
function is found.
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.
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 toner
lamp lights or blinks 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.
