hi! i have the same problem.......the toner is full but it always says to replace it.........thanks

I put a refilled cartridge in and it still says Toner Life End and won't print. I've unplugged and restarted, removed drum and cartridge and reinstalled --and it still says same thing and won't print or scan! When I try to scan it says check cable. It will send faxes. This is the third time I've replaced the cartridge (with a refill) and the other times I had no problems at all.

I've got the toner life end message too and can't get rid of it and it won't print--what do I do?
by sndckd on Apr 9, 2007 at 10:04pm Add comment
I had the same problem with MFC-7420 this morning. Here is what I did and message is gone.

1) Pull out the cartridge and look on the right side of the it. You will see a small hole that has a glass like window in side (round window).

2) Turn off MFC-7420

3) Cover the hole on cartridge with a duct or a piece of paper. Basically block.

4) Replace the cartride back in the printer and turn on the printer.

5) The message should be gone and you should be able to use the copier functionality.

It worked perfectly.

What an unethical practice Brother is follwoing? They want us to spend more moey buying their cartridge unnecessarily.....

This worked for my 8660dn printer. Thank you! - Anonymous
Thanks it worked great. I thought I was loosing my mind. I refilled the cartridge and made 10 copies and it was dead again. Now I can make about 500 copies with a refill and replace the cartridge only when the copies start to get light. - Elzbet
yoog, thanks very much for your fix, it worked like a charm and I'm appreciative.

Its very annoying that the printer decides when the toner cartridge needs to be changed and I can't help but think that this is just a ploy to increase sales of cartridges. I got the "end of life"message while the printer seemed to be printing fine and it doesn't appear that the cartridge needs to be changed right now. To make the printer non-functional at this point is really customer unfriendly.

I'll keep using it with your fix and I bet I get a bunch more printing done before it starts to fade and really needs a cartridge.

Thanks again. - unknown
Thanks for the tip, this worked great and was a easy fix. - unknown
Thanks alot!!

Message came out when I needed to finish a job.

Tapes a piece of paper over the window-like hole and it worked perfectly.

If printer displays "Toner Life End" after installing new cartridge, open front cover, press 'Option' button, then key *00 on the keypad. This resets the device so it knows it has had a new cartridge.

this will reset toner counter on a lot of brother printers good luck

The recommendation to open door and key in *00 worked for me. I didn't have to try the other tricks suggested. In answer to the question about asking this forum instead of the manufacturer, it's because I can find an answer here. I can never find one on corporate web sites.
Thanks for the help. - unknown
It worked for me. Thanks. I was thinking of remplacing the machine. I just saved a couple of hundred dolloars.

I have an 8660DN and the tape solution worked perfectly. However, I did not put the tape on the cartridge, I placed it over the left hand sensor on the printer. Turn printer off, then on again. Fixed for good now.

When your cartridge starts showing signs of running out of toner, shake it along it's long axis. You will get at least another hundred or two pages out of it at good quality. At the same time, order a replacement cartridge so you can have uninterrupted printing without having to run to a local store and have to pay too much for a new cartridge. - Anonymous
I had to reply to you guys and thank you for your advice.

I had my toner refilled and upon installing it, I still received the End Toner Life message.

I called Brother and they literally read their guarantee to me. They were of no help and the first rep was treating as if I was an idiot.

I have three Brother printers, if any of them ever break, I will buy other brands, never again Brother.

Thank you all for being involved.

Any Ideas on a Brother MFC 8420 - same problem?
by unknown on May 6, 2008 at 8:07am Add comment
For me, putting the black tape on both ends of the printer worked.
You have to take the toner out and look inside the printer for a little whole with a glass-like cover, put the tape on this. There is another one on the opposite side and I did the same to it and it worked for me.

I'm assuming all the Brother machines have this same setup.

Good luck.

One more time:

The MFC 7420 has a toner life that is tracked by the electronics.

This toner life value is reset by a switch activated by a tab on the toner cartridge. Once the value is reset, (by putting in a new cartridge) you can then use your old cartridge. Strange huh...

Anyway, you can also reset this internal value by opening the front toner compartment door and then press the "OPTIONS" button that is found under the COPY section on the control panel. When you push the OPTIONS button the message on the display reads "Replace Drum?". DO NOT respond to this... but simply type in *00 on the telephone key pad. (If you replay to this post and state that you can not find the telephone key pad on the 7420 then, you need more help than what will ever be available on this forum.)

Best of luck.

I found that when you open the front door and press options you need to clear the message of 1. yes and 2. no with the * key then put 00 and it is accepted. Then close the door and the end of life message will end - unknown
I found that if I did not respond to the replace drum prompt it then gave me a replace the drum soon message. I repeated the steps only this time only accepted the option 1 to replace drum and nothing else, and walla no more replace drum soon message. - unknown
Thanks for this post.

I have a Brother MFC7440N printer with an "TONER END LIFE".
How to fix this?

1. open the front door where you access the toner.
2. press the Clear/Back button. You will be shown a dialogue "REPLACE DRUM? 1.Yes 2.No
3. DO not type in 1 or 2! instead, type in *00 on the keypad and you should be rewarded with "accepted"
4. Close the front door and hopefully the Toner end life message will disappear.

It worked for me after lots of searching and trying different things.
- unknown
On my 7340, the steps I had to take were to:

1. open front cover where toner inserts
2. press the "clear/back" button. It will display "replace drum?". Do not respond to this.
3. press *00. A message "accepted" will be displayed.

All is good at that point. Hope this helps everyone! - Anonymous

These are great tips about the 7420 toner life.
Now what about the drum? I get a message "Change Drum Soon", and sometimes it works to take out the drum/toner, shake them, punch the printer (just joking), and put back the drum/toner.
But what is the real answer? What is a drum, anyway? And why are drum and toner separate units in the Brothers?
by unknown on Sep 11, 2008 at 5:27am Add comment
The drum is a cynider that helps imprint the toner onto the paper. They seperated it for ease of replacing and to help keep cost down since it does not need to get replaced as often as the toner. In fact, the drum unit is also the dust bin. Where all the waste toner goes. The drum needs to be changed so the dust bin can be emptied and cleaned.

I have successfully used the "block the window" with tape method, and the "Press Options *00 " method. Want to make your toner last and last? Contact TonerKing LLC, 1010 East Elizabeth Ave., Linden NJ 07036. Tel 908-587-1128 Fax 908-587-1138. I bought 2 toner bottles to refill my Oh Brother! MFC 7820. 2 Bottles cost about $20 including shipping, and each refill lasts about as long as 2 store bought high capacity cartridges, so in otherwords, $20 lasts as long as 4 single store bought cartridges! Be sure to vacuum out your old cartridge well and get out the old toner - was easy!

Thanks for the info... i've reset the printer after it advised that toner life was over, and I have been able to print over 1500 pages without replacing the first toner cartridge... I have a new one, but I keep resetting, and the thing keeps printing! I have to say that I would never purchase anything from Brother company again. I feel that this is dishonesty that they are just trying to make lots of money on their toner cartridges.

Put tape on a hole on the side of the cartridge= no help. Did the *00= no help. Turned a white screw looking thing on the left (it moved another arm forward)= no help. Put masking tape over the "lenses" on each side of the cartridge bay inside the printer, and used a Sharpee to black it out. Seems to be working now.

To me it should be my decision when to replace the toner (especially if it is printing perfectly!) not the machines, however my experience with other brands has not been any better- the benefits of Brother is that their accessories are everywhere and the TN-350 cartridge fits in a few different printer/fax models we have around the office.

That is my 2 cents.

I have the Brother MFC-7820N
I tried the suggestions from this forum, and each one gave me a few more copies.
1. I put masking tape over the right cartridge window, and colored it black with a Sharpie.
2. I put masking tape over the left cartridge window, and colored it black with a Sharpie.
3. I pressed "Option" *00 on the front keypad.
4. I used a screwdriver to twist the white plastic screw on the left side of the cartridge 1/4 turn clockwise.

But after a few copies, then the "toner low" message would return, and then "Toner Life End", and the machine would demand a new cartridge.

Next, I bought a new cartridge, and I would swap the old and new cartridge, getting a few more copies from the old cartridge each time... But very tedious. Then this trick stopped working, too.

So finally, I got some black electrical tape and put a piece over the round hole in each side of the drum unit that lines up with the cartridge windows.
So far I have gotten more than additional 100 copies from that old "starter cartridge" that had stopped several months ago with the "Toner life end" message.
It is still going strong, and not even a "Toner Low" message.

Now that this infuriating problem is solved, the machine is a delight to use.
Good luck to the rest of you.

8660 Update:

Entered the *00 message, did not work as it did the fist time. entered *99, did not work. Taped both sensors on the side of the toner and that was succesful. Thanks again all for the great posts. - unknown
I didn't try the tape solution. For Brother MFC-9840CDW
* Open front door
* Press Clear/Back
* follow menu for resetting different cartridges (don't know what is diff for S- and H- options, so I reset both)

This has been so frustrating since I've owned this printer-horrible toner wastefulness. I like everything else, so I am thrilled to have this work around. It has been super frustrating trying to get Brother support to offer ANY help. So I say, who needs 'em??? Thanks so much for the info sharing on this site!!

Hi Everyone,
Just bought a Brother DCP 7030. Ive replaced the Toner with a TN 2150, and now its giving me a toner life ends when it's still half full. Worst, I get this Drum Life End Soon message, when I just installed the new drum (about $90!!!).

Any help would be appreciated on how I can bring back sanity to using this printer. I've about given up on this, since we also called brother company, and thet said "need to replace the PCB (printed circuit board), of all things - tantamounts to saying buy again another brother printer.

That's plain bullying of customers.

by omargkdi on Oct 30, 2009 at 7:10pm Add comment
Hi, I had a similar situation with a DCP-7030, in which it was giving me a bogus 'empty toner cartridge' error and had shut down. FWIW, this is what worked:
(i) I covered the right hand window on the toner cartridge, using black electrical tape.
(ii) I turned the printer power switch off and restarted.
(iii) I restarted the computer.

I don't know if I had to do either of (ii) or (iii), but the printer's now working fine. Covering the cartridge window appears to be the answer for this error in the DCP-7030, as well as other Brother models.

Thanks to everyone who contributed to this thread-- I've got it bookmarked. - Anonymous

If printer displays "Toner Life End" after installing new cartridge, open front cover, press 'Option' button, then key *00 on the keypad. This resets the device so it knows it has had a new cartridge.

this will reset toner counter on a lot of brother printers good luck

I am troubled to hear that something as basic as resetting the flag gear was ALLEDGEDLY not able to be done by one of Cartridge World's franchises as it is a basic, old and common task during the remanufacturing process on Brother toner cartridges. Additionally, Cartridge World has a 100\% satisfaction gaurantee, so why your trying to solve the problem yourself is beyond me, as a replacment or full refund is exptremely easy to acquire...unless you were trying to get them to fix a cartridge you did yourself or purchased somewhere that a solution was NOT easy to come by.

On the left hand side of the toner cartridge is a small white lever, on a brand new unused toner this faces to the rear of the machine, once used it faces forward. This lever trips a reset switch inside the machine. Remove the screw on the cover over this lever, lift it out position it again facing the back of the machine, refit the cover and it will reset the toner count.
The toner sets a 2000 copy print cycle when the trip switch is reset, on the machine itself and will stop printing even if there is still toner left, I usually get between 85 and 110 extra pages printed before copy quality falls away. I have succesfully moved the lever to the rear using a small amount of force but have also broken the lever off on 1 occasion.

Thanks Pavelious!!! Black paper sticky taped over the ends as worked for mfc-7340 after I tried the codes which didn't.

What an ridiculous and appalling mechanism. I would have thought that when copies start looking a bit light that would be a good enough indication. I'm sure plenty of $s were wated because of this.

I bought a brand new cartridge from Brother and it didn't work. So I don't want to hear people saying I'm on the cheap or working the system. Here is what I had to do:

1. Open the front cover.
2. Press the clear/back button
3. Options appeared: B:tnr-s This is black toner reset for
standard or 110 cartridges
4. Arrow up or down to find the correct cartridge and size s- standard or H-high yield (115)

5. Select ok when you get the correct option. My was Cyan so c:tnr-s

6. Then press 1 to reset. Close cover and you are good to go.

I have MFC-8660DN and couldn't find the OPTION button, but putting a small piece of duct tape on the small round window on the right side of the cartridge did the trick for me. Looks like we cosumers are held hostage by the corporate bullies by these unethical business tactics.

i tried all the above, the only succesful attempt was comparing an OEM cartridge with the generic and seeing the difference.

left hand side of replacement cartridge is a semi circular shape with a little tab that can be moved from front to back of the little semicirle slot - it needs to be facing the printer if you were putting the cartridge in.

I also covered the little glass holes inside the printer cartridge cavity - finally seems to have fixed the problem;

I think you just have to just put the tab so it is facing the printer. Good luck, and yes the brother website is no help, they dont even recognise the MFC 7420 as a current product.

I am using the MFC-7340.

Had a "Toner Life End" message despite having printed less than 500 pages with a new toner catridge.

I placed a piece of masking tape over the round hole at each side of the drum unit that lines up with the cartridge windows. It works! The "Toner Life End" message disappeared. The printout is so good that you can tell there is still a lot of toner left.

This shows that Brother's printer has a design flaw.

Hello guys,

This was very helpful, I have a brother mfc-7440n and I tried the thing with the masking tape and also the "Clear/Back" key and *00, and I just got a few more copies but the message came back. I noticed this happened when I did it separately. So I used the combo but I used black electrical tape and the *00 option and is working like a charm. I already scheduled a visit with the brother technician and I was curious to find out if he knew what the problem was, he came here to check what the issue was, replaced the tonner with a spare one he had and same issue. He finally reset the entire device and it worked, so I guess restarting completely the printer is the same as just resetting the cartridge blocking the circle window and hitting *00.

Best regards from Mexico.

Same issue with an HL2170w / HL-2170w

Was actually a bit angered that it said "Toner end of life" when not 20 pages previously during a test page it said 30\% remaining!

However it refused to print anymore since it hit that message!

I Covered the sensor (glass hole) with a notebook hole reinforcer & Scotch Tape (to further secure it/make sure nothing falls into the printer later).... Fix worked!

And I'm glad too, The warning was nice to do the old "Shake and redistribute toner" trick, and with the sensor covered it was back to printing like a new cartridge -- much darker then previous prints.

Open door
press Clear/Back key
press *00
press OK

Do not choose anything for drum replacement. when drum replacement menu comes up, just press the * and then 00, then just press OK.

Worked for me, hope it helps

I must be the only person that this did not work for. Tried tape on all sensors - sharpie markers black - reset with the *00 - tried the reset drum - nothing works. And I bought the toner from Staples so it should work - right? Ready to throw this printer out the window. Any help would be appreciated.

Replaced toner cartridge with off-brand, compatible cartridge. Could copy, but could not print from computer. No error or end-of-life message, printer just wasn't receiving message to print. After trying several common troubleshooting techniques without success, I tried the old "unplug the printer power cord and then plug it back in" it worked.

For me it's about brother dcp-7030 and I found this: "I just had this problem and fixed it. The original toner cartridge that comes with the printer cannot be reset. You have to buy at least one new cartridge. The reason is that the original cartridge that comes with the printer doesn't have a reset flag. You can, however, refill/reset a cartridge that you buy separately. Pull out the drum and lift the cartridge out of the drum. Hold the handle and look on the left end. You should see a crescent shaped hole with a white flag/lever. To reset this, move the white flag all the way to the left (I had to use something to push it). Put it back into the printer and voila - it fixes itself. Then, after the printer has been reset, you can use the original cartridge again, if you want. The flag part won't matter once the printer has been reset. I hope this is clear. I know it worked for me, and I had the exact same problem."

I tried and it worked for me.

I have the brother MFC-7440N model, When I open the cartridge door, it says close door. If I hit the clear/back button, it beeps and says: cover is open, close the door. If I hit the option key, it beeps and says: cover is open, close the door. If I close the door and try pressing the options button, the option menu comes up (quality, contrast, etc.). If I press the clear/back key, it beeps.

If we have the same model, why can't I do this reset thing?

any suggestions?

Hello nmtsaki,
it's possible that Brother make a change in Firmware. Did you buy a new 7440N or make a firmware update?
What kind of firmware your printer have?
You can find it in the configurations menu 'Network Configuration' on main side. (my is 1.02 ?)

All people should note her printer firmware together with the post, so we can follow up the changing.
My be Brother are not 'At your/our side..' anymore, so they change to his pocket side!

1. Press the "*" and "#" buttons simultaneously.
2. The firmware version is displayed on the on upper left corner of the LCD panel.

Top of page four there is an image of TN360/TN330 cartridge(for 7440N).

Remove three screws and get the lever back to where the picture is showing it should be. put the screws back and put it back in your printer. WALLAH! it will now work for 7440N.

masking tape, *00 option or replacing the cartridge with the new one and putting the old one back DOES NOT WORK FOR 7440N. even if they work they will bring back the message of TONER LIFE END within couple of printouts

Only by reseting the way it shows in the image (TOP OF PAGE 4) will work

remove drum with cartridge unit
remove cartridge and put back in drum
Put drum/toner unit back in slot
Keep cover door open
press Clear/Back key
...Do NOT choose anything for drum replacement... when drum replacement menu comes up....
Just press the *00
then press OK.

BINGO !! I have a newer MFC and none of this worked -- but you all did give me the clue I needed.

1) Open the door to the printer cartridges

2) Press the CLEAR KEY

3) up will pop a menu that lets you clear the counters for the cartridges one at a time

-- you can clear for standard (STD) or high capacity (HC)
(the menu you will see is posted at the bottom of this message)

Works great now.

WAIT WAIT -- I just found two other posts around -- that indicate the BROTHER seems to keep changing STEP 2

If STEP 2 above doesn’t work try one of these

1- Turn on printer
2- Open front door to access toners
3- Hit the "Start" button for the Black and White copies on the right side of control panel
4- Quickly type in the number "10" on the numerical keypad (1 then 0, quickly in succession)
5- You will see a toner menu. Simply pick you color(s) and capacities and reset as needed.


Step 1.) Open front cover to expose printer cartridges and press #1 on the number keys.
Step 2.) Scroll down to find and select the appropriate toner cartridge to reset:

K.TNR-STD (Standard Capacity)
K.TNR-HC (High Capacity)
K.TNR-S.HC (Unknown)
C.TNR-STD (Standard Capacity)
C.TNR-HC (High Capacity)
C.TNR-S.HC (Unknown)
M.TNR-STD (Standard Capacity)
M.TNR-HC (High Capacity)
M.TNR-S.HC (Unknown)
Y.TNR-STD (Standard Capacity)
Y.TNR-HC (High Capacity)
Y.TNR-S.HC (Unknown)

After having replaced the toner cartridge (didn't I just do this a month ago?) with a new one and still getting the same "Replace toner cartridge" message, I used the advice in your thread of communication here for clearing the message. It worked! Important to note: Remove drum/toner cartridge. With a flashlight, looking inside the now empty printer chamber, locate the small, clear- windowed "holes" that everyone is referring to, which are found-NOT on the cartridge– but on the right and left inside of the chamber. I used a tiny tab of black electrical tape to cover each one. I then re-inserted the drum/toner cartridge. And with front cover still OPEN, it did NOT work for me to press "Options" as others suggest, BUT I clicked the "clear/back"button which is located on my printer panel next to the up/down arrow keys. Then override the "replace drum? question that appears by typing in * 00. Close the front cover and, voila, the message ""Replace toner cartridge" disappeared for the first time in months. So, I took out the brand new cartridge and returned the "old" cartridge and it still works great. I can now use my printer AND the old cartridge has plenty of ink still in it.

I tried other suggestions to no avail but finally found this suggestion and it worked!!

1. Open front cover
2. While cover is open and machine is on, push "options" then quickly push numbers '1' then '0'.
3. If step 2 was done successfully, you Brother machine will display the word 'accepted'. (If you are not quick enough in performing step 2, you will then have to start over.)
4. Once it's done, the toner cartridge is reset. Turn off machine and restart.

There is a small flag on the left side of the cartridge that must be reset in order to trip a lever inside the printer to let it know that the cartridge has been replaced. You can defeat the door interlock switch and manually reset the lever inside the machine or start using a quality remanufactured toner cartridge from a reliable refiller. I am always puzzeled when people give their hard earned money to companies that sell them a product, that product doesn't work right, and then post here to ask someone to help them fix their cartridge problem for free! How come you don't go back to the company that you actually gave money to and ask them? Just a rhetorical question-I really do not actually expect any answers.

Sue O you're not wrong, but I'm sure I can speak for several of us that the concept of "customer service" has long been dead in the Western Hemisphere, if not the world.

I've gone back to the retailer, and get back a "don't know". They must have enough business where they don't care much about keeping customers. So it goes.

Thanks for the tip, I'll give it a try.

What do you work for Brother? We would all love to use the manufacturer's parts except they charge you about 75\% of the cost of the printer just to get a new drum/toner. I tried calling the company and the company website and they were equally useless. They basically admitted that they were committing antitrust violations by forcing you to buy their supplies. - Anonymous
Thank you - you totally ROCK!
I have an HL-2140 and covered the 2 clear plastic holes with electric tape and now it prints.
What blows my mind is that I have already printed over 100 more pages and I am not even seeing any fading, so these thieves are forcing people to replace their cartridge when it is probably not even half empty!!!! I am contacting Best Buy where I bought it as well as Brother. I think you are totally right about not buying from scam artists like this, but is there really an alternative to buy, or is the alternative in forums like this where we share work-arounds? It is pretty sad how perverted making money has become, from a fair deal for everyone to people pretty much being robbed. - bina
I only use Brother manufactured cartridges and I still get this message even though the cartridge is not empty. When I shake the cartridge, the printer prints a few more pages and then the message appears again and the printer stops printing. This is apparently a flaw with the machine or the cartridge. It seems that covering the hole on the right side actually works. I never had this problem with HP and this will be my last Brother printer! - dangelob
Why did you even bother responding then. If you need to bitch to someone get a friend.

To respond without having to add a complaint is called BEING A NICE PERSON. Reading this makes me appreciate my son who would go out of his way to help someone just for the sake of doing it.
