The toner life end message means the toner is getting low. It will continue to print without any problem. Eventually you will see the print starting to get light in spots. If it is a new cartridge, the toner level sensors are probably dirty.

Toner cartridge is full - "toner life end"


when the printer is in "ready" state, press the GO and SET at exact the same time.

Now, using the (-) < button you can choose any "service" option to fine tune te printer

TONERLIFEEND is the first in the list, press the "set" button en chose "Nothing" and press "Set" again

Toner low, tone life end


There is a gear on the left hand side of the toner to reset the toner count this can cheated be rewinding it. Yes the design is to stop the refillers or at least slow them down a bit. If this fails purchase a new genuine toner but I have seen problems with the switch that resets the toner (Either the spring on the switch has popped off or the main board has failed).

Toner life end


There is no reset code the likely thing is that you have a faulty toner cartridge. Put another new one in and check the machine then.

Before you try the above shake the toner cartridge and tap it some more as it may also be the toner inside have become solid and needs breaking up.


Hope one of the above works for you
Thanks J

Toner End Life


Ther is a small viewport (about 1/4" dia) on each end of the cartridge that a photo sensor apparently shines through. The port is not near the bottom, so there's room for plenty of toner below it. Put a small piece of electrical tape over one of them and it will print fine..
Just a thought it worked for soe of my frnds..its worth a try..
Good luck!
