Resetting “Toner Life End” Error Message on Brother Printers

Getting rid of the "Toner Life End" message

BROTHER MFC-7420

If you own a Brother MFC-7420N or MFC-7820N you have in all likelihood seen the message “Toner Life End” after installing a new toner cartridge. This message makes no sense at all for the simple reason that the toner cartridge you just put in is new so how can it be at it’s life’s end? We couldn’t find the fix in the manual which is kind of strange seeing as that is the first place you would think of looking. Well come to find out  resetting “Toner Life End” error message is really simple, here are the basic steps you need to take to rid yourself of this annoying message.

STEP 1 – Open the front cover of your Brother MFC-7820N or Brother MFC-7420 so you can access the toner cartridge. (In some cases, you will need to remove your toner cartridge now for the next steps to work.)

STEP 2 – While the front cover is open and the machine is on, push the button “Options”.

STEP 3 – Push “Start”

STEP 4 – Then Quickly type “1″ and “0″ (like your typing the number 10). If you don’t perform this step quick enough you will have to start from the beginning. Don’t ask why, we don’t know and could not find an answer to that question even from Brother. We think they just like aggravating people.

STEP 5 – Wait until the machine show’s the term “Accepted” in the window.

STEP 6 – There is no step 6, your TN-350 toner cartridge is now reset and you can now print to your heart’s content.

  1. Our office own a brother DCP 7040 which was purchased about 3 yrs ago. It displays “toner life end replace toner cartridge”. We bought a new toner but same doesn’t function at all. Pls help us. Thanks. God bless.

    • Have you tried following the steps here? We’ve tested that this works in a DCP-7040, but if it’s not working for you, there may be a larger problem with the printer such as a short on one of the PCB’s (controller of power supply board), this would be a service center repair needed, most likely.

  2. I use DCP 7055 printer, I tried all the methods you have mentioned above it is still showing me the same message ” TONER ENDED”.

  3. I refill the toner but there is still replace toner being displayed on the screen of the printer. this regards the Brother DCP-1510 series. I could not do this. Also the Monitor screen is displaying empty toner. Please suggest the process after refilling the toner. I will be grateful.

    • If you’ve refilled the toner yourself, there is a gear that usually needs to be reset/replaced called, not surprisingly, the reset gear. This mechanical part is usually included with refill kits or you can buy them online for very little. This needs to be replaced for the machine to recognize your cartridge as new.

  4. This has been a constant issue for me. I finally decided someone must have found a way around this. One thing I did not see in your instructions was to remove the cartridge. I tried your steps many times with no success. Then I removed the cartridge and followed you steps and it worked. Maybe the reason I had to remove the cartridge is my toner is old, but the print copies are printing good, no degrading or skips. Thank you very much for posting.

    • Mari, yours is the first printer we’ve heard of needing the cartridge removed in order for this process to work, but I’m glad you figured that out and thank you for letting us know! We’re editing the article in order to reflect this, just in case someone else needs to do it also.

    • Aamir, the reason for a persistent paper jam is either: 1) there is still a piece of paper jammed somewhere that is VERY hard to see or small. I’ve seen whole sheets of paper accordion-folded into paper path components so tightly that you simply can’t see the paper at all until you remove certain parts. 2) Or another common problem is that a paper path sensor flag has been broken off somehow. The flags are very thin, fragile pieces of plastic that can VERY easily be broken off accidentally when using tools to dig out jammed paper. It could also be a failed photosensor in the paper path, but this is the least common issue that would cause this. We always recommend bringing your printer to a repair shop if you have “paper jams” that just won’t go away, they usually know how to fix them without making the situation worse, which can certainly happen.

    • We’ve seen a few suggested methods, but none of them seem to work (according to our readers). I believe this model has a service menu that allows you to reset the toner count, but the key press procedure to get to the service menu is what we are unsure of. There doesn’t seem to be a service manual for this or many other Brother printers that would normally explain the process. If you find out, let us know, we’d love to hear what works!

    • Hi Vishal, with an unable to print error (71 or 72) on Brother machines, the laser scanner unit is indicating it is encountering a problem. Each code means something specific, the service manuals for Brother printers are somewhat hard to find, however, and in some cases they aren’t much help anyway after telling you what the error is, they only give several parts that can be replaced that may fix the issue. About the only thing you can attempt to clear this problem yourself without major repair on the unit, is turn off and unplug the machine for 30 minutes to clear the volatile memory. Then replug and turn on the machine. If the error persists, you most likely need service. Either the LSU (laser scanner unit) or the Main PCB (printer’s “brain”) may need replacement.
      I hope you can get it going!

    • Hi Vera, We used to carry the toner cartridges for the HL-720, could that be the one you’re looking for? It’s the TN-200 cartridge and some places such as Staples do carry it still. We stopped refilling them last year as the empties became hard to come by. As far as I can tell, Brother doesn’t make an HL-7200 or HL-7xxx series.

  5. I really don’t hate my printer. Brother is OK. but my older ink jets in college were the worst, clogging heads, ink lasting a week. It’s an expensive SCAM. I think epson has even been sued in class action over it. You’d think by now they could make a cheap, dependable, easy to use printer. Same for cars though I guess.

  6. FIXED!!! Thank You!
    I have MFC-7440N and It didn’t work using “options” I hit back and clear and OK on the central pad and 10 really fast til it said “accepted”. It took 4 or 5 tries. I’m not sure which combo worked in the end.
    Thanks again.

    • They sure don’t make Brother’s user-friendly or very serviceable. They are good printers for most people’s needs, but things like this are why customers can’t stand their service. Glad this worked for you!

  7. There is also the electrical tape/duct tape trick, also… On the right side of the toner cartridge, you'll see a clear plastic plug over a hole (next to the "warranty void" sticker). Cover that hole with a piece of tape (must be dark and light-proof) and try the cartridge again :)

  8. The other main reason for a toner error light to persist is that the corona wire is dirty. This is located on the drum unit that the cartridges sits in. You’ll see a blue or green tab towards the end of the drum unit that goes into the printer first. Run that tab back and forth several times to clean the corona wire and then make sure the tab is back in its “home” position (arrows will line up on the the drum and tab). If you’ve already done that and the error persists, it’s usually because the corona wire is too dirty or worn, which replacing the drum unit will remedy. Our recommendation is to replace the drum approximately every 5th toner cartridge for best results.

  9. Please help me, the same problem, the same mesage Toner Life End
