1. Turn on the printer. 2. Push the button on the front of the printer to open the cartridge door. Do not remove the cartridges.
3. Push the Clear/Back button and hold till to bring up a reset menu. There are 8 different toner functions ( two Black, two Cyan , two Magenta, and two Yellow).
4. For each of these eight functions in turn, push the O.K. button and then push it again to indicate 'Reset'. After a few seconds, it will say 'Accepted' and will then display a message that the cover is open.
5. Repeat steps 3 and 4 for each of the 8 toner functions.
6. When finished, close the door and the status bar will be reset to normal with no error message.

You could try resetting the toner cartridge settings. OPen the machines front door where you would replace the cartridges. On the top panel you will see a "clear/back" button. Press it and on the display you will see a reset menu come up. Arrow to each one and hit the OK button. Press "1" to reset. Once you have gone through all close the front door of the machine and press stop to bring the display back to normal.

Hope this helps.

SOURCE: Keep getting Toner Life End Message even after replacing with brand new cartridge. I'm sure it is installed correctly. The Brother 7420 machine won't recognise the new cartridge(TN2025).

Open front cover and hit "Options" button, you should see a prompt to "Change Drum". Don't hit 1 for yes or 2 for no. hit the "Start" button and then put in the number 11. You should see the word "Accepted" in the window. Close front cover and you should be all set.

If your cartridge has a lever on the left side near the rear, it needs to be reset, and there's a lever inside on the left that can stick and cause that error. You need to wiggle and pull that lever until it moves freely again.

I have a Brother Laser Printer HL-5350DN. I refill toner myself but the toner light will not go out. How do I reset it so it goes off?


There is a reset gear in the cartridge that needs to be "reset" or replaced. I've included a link to a PDF file that goes over the procedure to properly refill and reset the toner cartridge. This is a document that is used by a company that does a complete rebuild, so you probably won't need most of the information, just the part on resetting the reset gear.

Hi, just replaced my toner on the MFC-7220 and a message Toner Life End is displayed and will not print. I have tried 2 brand new toner cartridges. Thanks, Linda


Hi there !

Try this solution if it works, the memory of your printer still programs that your toner is end.

Try to make hard reset of your printer by turning off your printer for 5-10 mins, unplug the power cord as well and remove the cartridge toner. Then return back the cartridge, plug the power cord and then restart your printer. Then try to print again.

If displaying still this message, just press stop button to remove the message.

Also, if there is wiper for cleaning the toner cartridge everytime your put new toner, please do it.

This is what we do in your bother MFC printer when this message appears. Just restart the printer and keep pressing stop button when the printer starts.

I hope it helps you. Regards.

I am changing the ink cartridge i put the new one in and it keeps saying End of life and it has a new cartridge what do i do


Here is the solution that will reset the count and allow your fully functional toner cartridge (the one the printer tells you is empty) to continue to work.

Open the front cover.
Press options button.
Press the start button.
Press + or up arrow button 10 times.
Press set button.

You have to do this with a long pause or the system will reset and you will have to start over.

Good luck.

Toner life end error message after replacing toner on my mfc9440cn


I took the printer back to staples and returned it. exchanged it for a new printer.

when I brought it home, the new cartridges worked just fine. It was not the cartridges, it was the printer's problem. Thenk goodness i bought and extended warranty on the printer.

The cartridges were brand new and name brand so it didn't make sense that it could be that all 4 brand new cartridges were having a problem!

MFC 8460N giving Toner Life End message


I just solved my own problem. Try it for yours. I had been using several compatible toners for the MFC-8460N with no problems until today, as I posted earlier. On a hunch, I went to the local office supply store and purchased one original Brothers TN550 toner and put it into the printer and closed the cover. Everything clicked. Toner End Life message gone. I then took that Brother toner out and put the compatible one back in and still everything was fine. Am keeping the original Brother toner as a "kickstarter" if it happens again.

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
