Brother toner cartridge low toner override

Am using Brother HL-5170 DN and a TN-540 toner cartridge. The printer decided it was out of toner, even though the last page printed was fine. Rather than run out for a new toner cartridge I used a small (.5 x .5 in.) piece of black electrical tape to cover the sensor hole on the non-gear side of the cartridge. By covering the hole the printer is fooled into thinking the hopper is full of toner.
since i finally figured this out I thought I would post this for anyone who has the
HL-4040 CN printer - or one similar
After seeing the hitting the buttons with the door open tricks for different models I tried anything that sounded like it had the same buttons my 4040 has... nothing on here worked so I just started hitting combinations of buttons with the door open - wow there are quite a few hidden menus there

For the toner life reset menu:
1 Open the front cover of the printer
2 press and hold the cancel button
3 press the reprint button while still holding cancel
- here is the reset menu - go to the appropriate cartridge on
- the menu and reset it and you're done!
FYI... Pressing the "Go" button and the up arrow gives you the parts life reset menu (drum, laser, fuser, etc.)

I also did the electric tape over the windows - which worked before the reset - but I thought this fact would be helpful too.

For anyone that is asking "what window?" I think it is the clear plastic opening on the sides of the cartridges where you can actually see the powder inside the cartridge - the color of the toner (magenta, yellow, or cyan). I didnt really know that for sure when I tried, but it made sense, and it worked. So I am fairly sure that is the "window" you should be trying to cover.

you are a genius.
worked for me. - Anonymous
Thank you!!!! I have a 4070 and your trick worked perfectly! - unknown
Hagan thank you for posting that for HL-4040CN. It worked! - Anonymous
Awsome post. Directions are perfect. This will save loads of cash as we have (3) of these units. - Anonymous
You da man! I figured out the optical, but the reset I never woulda thought of. thanx - Anonymous
Excellent tip for the 4040CN. Many thanks - Anonymous
I had read all the post so far and tried all the tricks. The tape over the holes worked for the black but not for the color cartridges. No one seemed to have model numbers close to mine (4070cdw)Then I saw this and thought the numbers were close enough. I tried it, the cancel and reprint buttons. Happy day, it worked. The menu poped up, reset, accepted, and I'm back in business.

Thank you so much for posting. You made at least one person very happy today.

I know it's a little late with this but I'm a fellow HL-4040 CN owner and just wanted to extend my gratitude. I have looked ALL over for this solution. I taped the sides, tried other reset methods, etc... This was the only one that worked. I don't know how you figured it out, but thanks!!

On side note.... it really gets me that Brother would actually STOP me from printing until I go out and spend $100 on their overpriced toner. I could deal with an annoying reminder, but total inability to use the printer in unacceptable IMHO (especially when their customer service is trained not to give you the real answer your looking for...) - unknown

Thank you so much, hagan for posting the reset menu directions for the HL 4040!! I'm on my second cartridge (1st was the starter and now I have the high capacities in) and am already sitting at 8900 pages printed. Of course this is due to covering the toner sensor windows. Resetting the toner life via the menu isn't a complete solve though - it still does stop printing before the actual quality of the print is affected but by the time it actually refuses to print with the cartridge, I've managed at least 1000 extra pages per cartridge. This alone is a HUGE money saver! I miss the old printers that kept printing even when there was no toner left! I love Brother printers but I wish they would let US determine when the toner needs to be replaced instead of a stupid printer! If anyone has any better fixes (apart from buying a new toner cartridge), please keep posting them here! This is a super thread! - unknown
FABULOUS! I have a HL-4070CDW and Hagan's "toner life reset" instructions worked like a charm. Much Thanks for the info. - Anonymous
I tried the black tape over the holes on both sides of the tray, lights still flashed.

Got into the reset menu and got choiceslike
b.tnr s
b.tnr h
y.tnr s
y.tnr h
and so on

what does the S and the H stand for
which do you reset

how do you find the drum, laser, fuser, etc. selections? - browneye
Dude you rock!! Thanks for fiddling around, worked great for me and now i can use the tonor cartrages i knew were good. (I put the yellow in black, and so on had em all print like they were black, so i knew they were fine.) Now i'm back to printing in wonderful color, and don't have to replace the cartrages for the insano amount of $$ yet. - Anonymous
Works perfectly - many thanks. - Anonymous

Worked like a charm on the HL 4070 cdw! - unknown
You guys are awesome!!! I have an HL-4070CDW. Been through a couple cartridges so far, I can see toner in there but no go. It really pissed me off to see the toner moving around in there plus the cartridges are still heavy!

Read all your notes and found the "eyes" are little light/windows that are flashing inside this printer. I had to take out the toner tray that holds 4 cartridges and I put tape over the little eyes on both sides. There were eight total, four on each side of the printer.

Still didn't work.

Then I tried your Cancel, Reprint deal and walla! We are printing! I cannot tell you how happy I am about this. You guys are all geniuses and deserver a medal of honor.

I bought this printer so I could print double sided and save trees only to discover now I am throwing away toner cartridges. Now I have solve this it is GREAT!

THANK YOU SO MUCH! - unknown
The trick posted by hagan worked like a charm on my 4040. I initially tried to cover the hole, and it did nothing, but resetting everything worked, and I'm hoping for results as great as everybody else has had.

Thanks, hagan! - unknown
BEAUTIFUL FIX- thank you ! I have a HL 4040CDN and the covering of the holes doesn't work for this printer - snuggycat
As for the 4040CDN This worked for me after the failed tape attempt. Thanks Hagan

For the toner life reset menu:
1 Open the front cover of the printer

Thank you hagan! I was having trouble getting to the toner life reset menu. Found it with your instructions and it's finally working. - TsaP16
I have a Brother HL-2170W printer, which has worked fine and printed what seemed like a reasonable number of pages for a starter cartridge before the "Toner" light came on. When that happened, I took it to a Cartridge World store and asked if the starter cartridge would work if refilled and was told that it would.

But when I installed the refilled cartridge the Toner light refuses to go off. After some research, it appears that there's a "Reset Gear" on toner cartridges for the Brother HL-2170. One source said the Reset Gear can't even work on starter cartridges, yet others are selling the Reset Gear saying it will work on starter cartridges.

Meanwhile, I have also come under the impression that there's a sequence of button pushes on the printer that will reset the Toner Counter. Does anyone know what that button-push sequence would be to do that? Thanks!

Brother use a system of returning the residual print waste toner from the drum, to the toner supply hopper, via a charge brush which is in contact with the drum and charged differently during the clean cycle of the drum. The charged residual toner is transferred back to the developer roller and dropped back into the supply hopper. This is why most Brother cartridges, unlike most makes, do not have a waste toner hopper in the drum unit. When the toner is getting low, the electronics increase the charge on the developer roller to compensate for the mix of waste and good toner. This process continues until the maximum charge can no longer be accepted by the toner. This results in the charge brush failing to operate properly and hence waste toner is not returned to the toner hopper, but remains on the drum. This causes the backgrounding which appears on the printed page. Even blocking the low toner sesor will not prevent this from happening. This is a brief description of a rather lengthy complicated prcess. Submitted by Robbo.

Can you help us understand how toner out works on other printers work like hp?
I am also I want to know how the component mix of a print job-vectors, text and bit maps affect toner use. What is the mix of iso documents used to establish yield? - Anonymous
I have the 5250DN. I covered the 'eyes' on both the left and the right. No go, still says no Toner.

I've tried a new cartridge and fuser, no go.

Anyone?

I had the same problem, the LED sensor block did not work.However, ...

There is a "flag gear" that, it seems, slowly turns (counterclockwise) as the toner cartridge is used, which finally hits a stop that appears to force the toner light on and prevent printing even if there is toner left. I have a TN550 cartridge which was refusing to print, and indeed the gear was at the stopping point. To reset the gear, take the cartridge out. On the gear side take off 2 screws, the flag gear (on the tn550) is the black gear on top right side, with a small spring underneath. Just take it off and reset it (rotate clockwise) so it is not at the stopping point.
I did not reset it all the way because there was some indication in other postings that it controls certain voltages that depend on the toner level. I assume my toner is actually getting pretty low so I just turned the gear back a little bit, and the toner light turned off, and the printer prints.

See the end of this toner refill guide for a photo of the "flag gear":

Leave your old drum unit in the printer. Then reset the drum counter, just as you are told to when installing a new drum. The old drum will now indicate it has 100\% life left. And it will print perfectly for another 20,000 pages. That's another year for me. (I wouldn't do this trick on the same drum a second time, as parts may start to wear out and cause damage to the printer.) I discovered this when I was replacing the drum with a new one, and mistakenly put the old one back in - and it kept working. Saves you up to $180! - unknown
Can you tell me how you fixed your problem without replacing the drum unit? I couldn't tell from your answer.

I cleaned the laser scanner windows and corona wires of the cartridges, but still have streaks on large shaded areas such as the header row of a text box. Thanks.

keep the front cover open (make sure the power is on) press and hold the GO button until all 4 LED s are lit up, close the front cover. Make sure the drum LED is off. The counter is reset! - Anonymous
Hi-

As a small office user of Brother MFCs for a while, my experience is that you can keep using it (ignore the message) until bad copy quality. This can be quite a while, even several thousand more. Then replace the drum and don't forget to reset the message. - JPLDOC
Brother MFC 9440CN Toner Life End Message... The Final Solution!!!

Having gratefully read about how to defeat the toner sensor window with black electrical tape, I went to work.
Sadly, I was crushed to discover that performing this operation did not solve the problem for my accursed unit.
[Do it anyway as it will save you from these annoyingly premature warnings in future!]

Reading further, I became convinced that a reset process similar to that used to solve this problem for the Brother 2040 and 7420 models was also required here.

With nothing more to go on than responses to my emails from the good people (knuckleheads) at Brother telling me only how to install a new cartridge, I began poking around on my own 'till, after much swearing and gnashing of teeth, I figured it out:

1. With power on, open the toner access main door (You will get a "door open" message in the LCD.)
2. Hit the "Clear/Back" button and... ta-dah!!! you go right to the “Toner Reset Menu” (cue Vienna Boy's choir sounds here).
3. Using the up ^ Down > "Search" arrow buttons, you can then scroll through reset options for each of the printer's [4] toner cartridges!
Code: B. = black; C. = cyan; M. = magenta and Y. = yellow
4. For each for these cartridges is the option to reset for low yield = S (small?) or High Yield = H
5. Using the number keypad, select option #1 (to reset each to the size you have installed.
6. Hit the "Clear/Back" button to get out of the menu, close door ad the problem is FINALLY solved.

Cheers!

Yippee!! I have an MFC-9840 CDW printer, and I followed all the instructions about the tape and such, but to no avail.. Then I read your post on how to reset the toner cartridge within the printer and PRESTO! Worked like a charm! I had one that I refilled and still had the "toner life end" message on the screen, and one that was just a "low toner life" message. This trick fixed them both! Thanks so much!!!!

Brett;

Thank you so much for your instructions on how to reset the Brother MFC9440 printer. I have a MFC9840CDW and used your instructions with instant success! I am in your debt. I have been waiting for 3months for `tonerrefillyourself.com' to put their color toner on the market. I have been using them for about 4years now (Starting with my Sharp 1551CS and then my HP LJ4100). I trust them as they do not use `fit's all' type toner. They also include instruction on refilling each cartridge.

Thanks again,

This is the beauty about the internet. After wasting almost 30 minutes in the phone with customer support from Brother, the only advise they give me was to replace the cartridges, even when I was telling them I didn't use the printer (MFC-9840CDW) a lot since the last time I replace the cartridges. Anyway I went online and find this site, but even closing the holes with the tape wasn't working, until I found your post about resetting the toner (THANKS A LOT MEN) very carefull I opened on the the cartridges and notices that is almost half of the life toner in there. BROTHER is killing us making us replace the cartridges when there's a lot of life remaining on them. But thanks to people like you, we can use the toners and cartridges until the end as was supposse to be. - Anonymous
Thanks Brett !!

Brett In SoCal,

I just had to thank you so much for that advice. I combed the internet to no avail. And usually I wouldn't have the chance to thank someone for helping me fix my printer because I usually spend all night trying to fix it. Not this time!

You sir, single handedly solved my printer dilemma without tape, markers, or fooling around for hours. Brother should hire you instantly, and I would even give you money for that tip, except I was printing a resume and cover letter for a job interview tomorrow. Unemployed :( So I've currently got none to give.

But think of like this, you may be responsible for me landing me a job tomorrow AM. I'll let you know. - unknown
Another big thank you!!! Covering the sensors didn't work (if I even found the right ones.) I would never have known how to find the toner reset menu. After replacing the black cartridge, my printer - the 9840 - thought it needed all three color cartridges replaced, too! Too much of a coincidence, could not be true. This website is a true blessing. Thank you, thank you, thank you! - CB in Indy

Thanks to Brett in SoCal (06/29/2008 4:57 PM) for a far-out software fix. Resetting the toner warnings was simply a genius solution to the "toner low" and "toner end of life" warnings for the color cartridges that I hardly ever use in my Brother MFC-9840CDW. Loved the elegance of getting into the reset menu rather than mucking around with electrical tape (I couldn't locate the sensor openings anyway). My MFC had quit printing and copying in b&w too suddenly because the color toners were apparently dead - this solution saved me an emergency run to the local store to buy extremely expensive and unnecessary toners.

Thanks very much. - unknown

Hi Brett....you are my new hero! I have an MFC 9320 and I have nearly resorted to "printricide", (or should I say Fratricide?) I called Brothers service folks believing foolishly that they were competent and they tried to explain to me that 3 Black Toner Cartridges (and now all 3 color at one time) needed to be replaced after 60 days of use. (I even went to the trouble to count the number of pages) Bottom line? Brother is trying to shaft their customers. Your fix was exactly what the doctor ordered. Essentially, I would have spent the cost of the printer every 60 days in toner. The add on I would mention is that the Reset Fix calls for STD and STR for each color, instead of H or S. I have no idea what STD or STR mean, so I did the same reset function for all 4 colors twice. Now its all good! I appreciate it very much. You have saved me hundreds of dollars and my neighbors from hearing me swear at the top of my lungs out my office window, and probably Brother from receiving their printer in small pieces in a ticking package. Although I am not through with Brother yet. I should see if I can find this tidbit of yours in the directions, if I do, I will perform contrition for all my imagined acts of violence, and heed my wife who asks regularly if the instructions to any device serve any useful purpose in my modus operandi.

Again, thank you!!! - Anonymous
Brett In SoCal's steps to reset my Brother MFC 9440CN worked like a charm! The tape fix did not work until the printer was reset. I had the End of Life toner message for three good toners (the color ones...as if they all run out at the exact same time, give me a break). Now, thanks to Brett, they are all working fine.

Thanks so much BrettInSoCal, from Sam in NoCal! - manucru
Awesome. It worked with my mfc 9840cdw! Thanks! - unknown
Thank you so much for taking the time to post this. This tip saved me a lot of money and hassle, as I was in desperate need to print something and the toner I had ordered online took well over a week to arrive (I got the wrong parts at first). Your tip allowed me to print in the meantime, and without paying an arm and a leg to do so.

Part of me thinks that Brother should have a class lawsuit for forcing users to buy new toners when the existing ones still work just fine. Of course they are a big company would likely still manage to appear as the good guys.

Thanks again.

Thank you for your fabulous information! I just stumbled across this thread when I was so frustrated that I was about to replace my toner cartridges YET AGAIN for my less-than-a-year-old MFC 9440-CN. I actually purchased a refurbished model for about $300 and I am realizing that I have already paid for the unit once over by purchasing another full set of toner cartriges less than 4 months after purchase. I do quite a bit of b&w printing, but not a ton of color and was pretty upset that Brother was screwing me again (I used to have a brother fax machine that would tell me the color and black cartridges were out of ink and it would stop printing when I could SEE the level and we NEVER used color on the fax machine...).

Thanks to everyone here, Brett in SoCal especially, for GREAT info! I am going to bookmark this page and check back for more great tips. I used your tips for reseting the toners and it worked! We're up and running again and I can postpone dishing out another couple hundred bucks for toner for a few months more! :)

For the Brother HL-4070cdw, if you get the Tone Life End message, and are no longer allowed to print, try this...
1) Open the front door - the message 'Cover is Open' will appear.
2) Press and hold the cancel button.
3) Press the Reprint button - the message 'Reset Parts Life' should appear.
4) Then do the following:
B.TNR-H - accepted should display. Press ^
B.TNR-S - accepted should display. Press ^
Y.TNR-H - accepted should display. Press ^
Y.TNR-S - accepted should display. Press ^
M.TNR-H - accepted should display. Press ^
M.TNR-S - accepted should display. Press ^
C.TNR-H - accepted should display. Press ^
C.TNR-S - accepted should display. Press ^
5) Cancel
6) Close the front door.

You should be able to print, assuming your HL-4070cdw still has toner and drum life left.

I believe the above sequence clears the toner for Black, Yellow, Magenta and Cyan for the High capacity or Standard capacity toner cartridge.

None of the stats for your printer will be reset (ie Image Count, Drum Count, Drum Life, Belf Life, PF KitMPLife, PF Kit|Life, Fuser Life or Laser life) and your print totals will still be unchanged (ie Toner page count, color page count, monochrome page count).

Thanks, tsatiyeh! Your solution worked perfectly for my HL-4070CDW.

Little things that I didn't catch the first time I tried to reset the cartridges:
- You have to continue to hold "Cancel" when you press "Reprint"
- At each label I had to press "OK" twice to reset before pressing ^ to progress to the next cartridge - Trose
The 9840CDW, a very similar unit to the 4080, has similar re-set functions. In order to get into that menu on the 9840, open the door and press the "Clear/Back" button. - davagain
Thanks Tom.
And for those who are a little more technically oriented, the following link will show how to physically reset the "counter gear" on a TN-110 or TN-115 cartridge. This reset gear is what causes the printer to realize a new cartridge has been inserted.

www.uninetimaging.com/newsletter/Brother_HL_4040_TN_115_Reman_eng.pdf

Do pages 7 and 8, then jump to page 12 to see how to reposition the counter gear and replace the gear cover.
DON'T DISMANTLE THE WHOLE CARTRIDGE ! !

For those trying to locate the "holes to tape over", they are the clear plastic "plugs" on each end of the cartridge. You only need to tape over the one that is easy to reach.

For those trying to find the "reset switch" on a 4070, quit looking. It's buried inside and cannot be activated manually. Resetting the "counter gear" (above) will activate the reset switch. And it must me done for EACH cartridge, as needed. Meaning you don't have to do them all at once.

Y'all have fun, now. Ya heah! - Anonymous
Thanks!

You are a genious. This worked for my brother hl 4070 cdw toner life end error message.

In reply to Tom:
For the Brother HL-4070cdw, if you get the Tone Life End message, and are no longer allowed to print, try this...
1) Open the front door - the message 'Cover is Open' will appear.
2) Press and hold the cancel button.
3) Press the Reprint button - the message 'Reset Parts Life' should appear.
4) Then do the following:
B.TNR-H - accepted should display. Press ^
B.TNR-S - accepted should display. Press ^
Y.TNR-H - accepted should display. Press ^
Y.TNR-S - accepted should display. Press ^
M.TNR-H - accepted should display. Press ^
M.TNR-S - accepted should display. Press ^
C.TNR-H - accepted should display. Press ^
C.TNR-S - accepted should display. Press ^
5) Cancel
6) Close the front door.

You should be able to print, assuming your HL-4070cdw still has toner and drum life left.

I believe the above sequence clears the toner for Black, Yellow, Magenta and Cyan for the High capacity or Standard capacity toner cartridge.

None of the stats for your printer will be reset (ie Image Count, Drum Count, Drum Life, Belf Life, PF KitMPLife, PF Kit|Life, Fuser Life or Laser life) and your print totals will still be unchanged (ie Toner page count, color page count, monochrome page count).

This worked for me-- also the manual for the 4070CDW has the wrong instructions for resetting the drum count/life. I was going crazy trying to find something that would work after replacing the drum unit.

I found that I coould use these same instructions with one modification for resetting drum life/count

1. Open the front door
2. Press and hold the cancel button
3. Press Go and "+" and you get the "Reset Parts Life" menu with Drum Life option
4. Press OK twice and you get the "Accepted" message
5. Cancel
6. Close the front door.

Thanks for the tip!

This worked for me - I have a HL-2040. It resets the page counter:

1. Open the front cover and leave open while completing the following steps.
2. Turn the printer off.
3. Hold the 'go' button while turning the printer on. All panel lights should be on.
4. Release the 'go' button.
5. Press the 'go' button 2 times.
6. Pause.

I bouught a new toner cartridge and after installing it the printer would not work. The toner light stayed on. I followed your procedure and reinstalled the printer driver software. The printer is now working.
Thanks for the advice. I am impressed.

I got this same solution directly from the brother people. They refused to talked to me until I was able to find the brother serial no. on the bottom of the toner cartridge. they also wanted to be sure that I wasn't using a refilled cartridge. this solution should have been on their web page. the only reason for it not being there is the sale of additional brother toner. - unknown
You have no idea man! May be 2 years since you put up your post -I've literally spent hours trying to get my toner going on my Brother HL 2170, had to print highly important stuff, tried all the previous tricks, I blocked the 'eyes' with 3M tape! NOTHING worked. I was on the verge of giving up when I read your post - I gave it a shot and it WORKED!!! So, thank you so much for posting that!

I have the Brother DCP 7020 which uses the TN-350 cartridge.

I covered both "windows" with black tape, the two circular plastic openings on either end where you can see the toner inside.

I also covered the sensors inside the machine with black tape.

I did all of this, turned the machine off/on and it still says "Toner Life End".

I think the problem is with the gears, as this starter cartridge does not have the flag gear on it.

Does anyone know how to fix this specific model with a hidden reset menu or anything?

I have ordered a reset gear for it, but I really need to use it NOW! I have invoices that urgently need to go out.

Thank you,

Hello everyone!

Most of the Brother Printers even the color ones such as the 4040 & 4070 use 2 different toner detection systems. Many have the sensor "window" which can be covered with black tape but also have a "Flag Gear". The flag gear causes the cartridge to completely lock up the printer at a certain point. This is because the brother printers also use a toner recycling system which will adjust voltages depending on the toner levels detected and the flag gear position. The workaround is relatively simple for each printer but does vary. If you are interested in more info send me your specific model number and I may be able to send you a helpful illustration in pdf format. My email address is [email protected]

Thanks for the offer to help.
We have an hl - 2170w and a 2140 , the cartridges are interchangeable. On the 2170w the toner light stays on even when I swap out cartridges ( they're both full). I even put a new cartridge and carrier in it! Yet they both work in the 2140 unit. It seems there is something in the printer itself that needs to be reset or is broken. Any suggestions would be greatly appreciated!!! - unknown

I've begun getting a warning message on my MFC-9840CDW that the drum needs replacing, so I'm just wondering whether a) it will also disable (hit a hard stop) the printer at some point and if not, b) what is the issue with continuing to print without replacing it? The drum is basically the tray that holds the 4 toner cartridges...correct? What is there to wear out with that? Thanks!

We successfully reset the toner end message and have happily continued to print. Eventually, even though the toner window shows that there is still lots of toner in the cartridge, the cartridge starts to "spew" toner, not only on the printed paper, but inside the printer. Is there anything we can re-set to stop this? Maybe the flag gear? Edited to say that we have the Brother HL-4040CDN

i fixed the problem on my HL-2140 by resetting the "flag gears". Thanks a lot you guys out there. Here is a copy of the info:

There is a "flag gear" that, it seems, slowly turns (counterclockwise) as the toner cartridge is used, which finally hits a stop that appears to force the toner light on and prevent printing even if there is toner left. I have a TN550 cartridge which was refusing to print, and indeed the gear was at the stopping point. To reset the gear, take the cartridge out. On the gear side take off 2 screws, the flag gear (on the tn550) is the black gear on top right side, with a small spring underneath. Just take it off and reset it (rotate clockwise) so it is not at the stopping point.
I did not reset it all the way because there was some indication in other postings that it controls certain voltages that depend on the toner level. I assume my toner is actually getting pretty low so I just turned the gear back a little bit, and the toner light turned off, and the printer prints.

MFC-9320: I used the instructions that "Bret SoCal" posted and it worked like a charm. No electrical tape needed.

1. Open the lid
2. Press "Clear/Back" button
3. Use arrows to select toner in question ("std" or "str" I assume is for "standard" or "starter"
4. Select option #1 "reset"
5. LCD will read "accepted"

Yes -- you open the top cover and then hit Cancel and Secure Print at the same time.

This brings up the toner cartridge menu.

You can scroll up and down through the 4 cartridges (2 entries per color for some reason) and Press OK twice for each entry.

The printer will briefly show Accepted for each reset.

After doing this, I am still printing on all four of the starter cartidges and I did not cover any windows with tape or any of that stuff.

Good luck,

On a MFC9840 the blue and yellow cartridges are spitting
out toner!! Well, maybe not "spitting", but putting out
much more toner than is needed to print. There are
vertical smudges all the way down each page. I changed
the old toner cartridges, since they had been refilled,
and I thought that was it. But "nooooo"!
No matter how many times I clean it up, clean the wires,
shake off the cartridges, it just keeps on. AND it is
getting worse.
Anyone have any help for me at all?????

How to get more black and color toner out of my MFC - 9320CW
I covered the two sensor eyes on the right and left of the inside of where the cartridge sits... and since it would not print with this step only, I had to (while it is open) press the Clear/Back button and then the "ok" button and then follow the instuctions on the display screen to "Reset" it. (option #1)
Don't forget to do this same reset step for each color twice. I will paste the directions below that someone posted earlier so that you can follow his step by step instructions on how to reset each color two times.
Now my MFC 9320CW works so that I can be more efficent with the toner that is STILL in the cartridge and get more out of it!!
REPOST:
As a fledgling "work arounder", I discovered that by covering up the sensors, I failed to stop the "beep beep beep" and exclamation point demanding I replace the toner cartridge. WHat I DID discover was that even though it beeped and made its demands, that I could continue to print! (Which before doing the electrical tape/sharpie trick, I could not do)

Having said all that, the best solution was the one that I adapted from "BrettSoCal"'s post from June of 2008. I think this may work on newer machines (my 9320 is a newer model too). Basically, with the power ON, you open up the door to access the toner cartridges, and then look at the Menu which will tell you the door is open. With the door open, hit the Clear button. That takes you right to the Toner Reset Menu. Using the up/down<>"Search" arrow buttons, scroll to the RESET option and then for EACH version that displays (for Brett's it was B= Black, for mine its K= Black, then C for Cyan, M for Magenta and Y for Yellow, followed by option for either STD or STR on mine, but on Brett's its H or S. That means you reset a total of 8 "cartridges", NOT REPLACE DRUM, just hit the #1 option for each. Then hit Clear /Back to exit the menu, and close the door. It will whirr and spit and whirr some more (sounds like an old PP and M song) and then will congratulate itself on "resetting" and you can print to your hearts content. Brett tells me he hasn't replaced toner since!!

You may have gone the wrong direction if you picked up the "REPLACE DRUM" option, not sure, but I was really happy when this worked on my new MFC 9320. I put my electrical tape away and returned my black sharpie to my graffitti drawer. I know now what it feels like to be free! But I am seriously going to raise some serious hell with Brother. This is a deliberate effort to bilk their customers.

I print about 5000 to 6000 sheets of paper per year. Last year I owned an HP. I spent about $500 in cartridges, mostly Black and Yellow. I may have replaced one or two blue or magenta.

I have owned this Laser machine for about 60 days, in that time, I spent $210 in black toner cartridges and were it not for Brett (my new hero as I explained), I would have also had to purchase ALL THREE color toners, starting with Magenta. That would have cost me another $200+. At this rate, I would have burned through the cost of the printer itself EVERY 60 DAYS.

I was livid and made moreso when I talked to not only the tech at Brother, but his supervisor, both of whom were fatuous, condescending jerks, who when I confronted them that the Laser Black toner cartridge claims to be able to print 2200 pages, intimated that I must be outside the ASI standards with what I print. (I suppose to them, that must mean that I spend my waking hours converting white sheets of paper to black construction paper)

Anyway, I digress. Try what Brett recommended and that I refit to my new unit. The principle is the same.

Then lets all find out for me who the appropriate VP or CEO of Brother is and lets all get together and sue their miserable corpuscles!

Hope this works for you! I am tempted to go the store and try it on every Brother floor model just to check it out. I may do that and encourage others to do so, just to provide more info to others. I am so grateful to those on this site that have been courteous enough to take the time to respond and judging by the string here, saved many thousands of dollars, or more, for all of us. I am really fired up about this and feel like Brother is really screwing their customers. This is not just a minor issue, this is a HUGE and deliberate misrepresentation.

Works for a DCP1000 also.

Just cover the eye that you can see in the bottom of the machine after removing the imaging cartrige with a small piece of electrical tape. When your getting low on toner you'll notice it on the prints.

Replying to my own note, after taping over the toner "hole" I was able to print about 1000 (yes one thousand) more pages before the low toner light started coming on again.
This morning I started a print session and got a "hard" low toner message that stopped the printer from printing ("toner end of life" on operator panel).

I removed the cartridge gently shook/rotated reinserted and we're printing again....

While black areas may not be "fully saturated" printing is still very good -- What in the !@#\%#$^#\%&#$^@\%@# is Brother doing to us here? Ok ok ... I realize all the money is in consumables ...

Sorry....

Thanks for any comments!

brother HL5250dn status light is highlighted in red and toner light stays on even with a new drum unit and toner cartrige. - Anonymous
The tape over the window works! Yeah! I had just printed about 400 pages (biggest job i've printed on this 5250DN, which I LOVE, by the way!!!). Then all of a sudden, message, End of Life on the toner as confirmed in the software control panel. Scratched my head. Swore. The printouts had all been perfect, no lightening, or ANYTHING, and i just KNEW there was still toner in that cartridge (I could HEAR it shaking the cartridge!).

Long story short, read the excellent post here, took a piece of scotch tape and carefully covered the hole over the sensor window on the non gear side, and then took a black permanent marker and colored in the tape over the sensor. Popped it back in place, worked like a charm! I love DIY shit like this! Besides I was really pissed off that Brother would decide FOR ME when MY cartridge was empty! I mean, COME ON! As George Orwell predicted, Big "Brother" is watching, but we still have power! Yahoo!

Thanks all!!

My 5250DN informed me that I was "out of toner" at a page count of 3050 pages. I applied the fix above and now at the 4880 mark - not bad. I am now getting some "background" dusting / gray that is pretty evenly distributed over the entire printable area page.

Just to make sure there was not something else wrong I put in my new spare cartridge and it prints fine, so I guess at some point even toner still available something else is going on inside the cartridge... I understand there is some type of "toner recycle" mechanism in there that might be causing the dusting, but have never had one of these units apart.

If somebody knows of another way to clear up the background toner dusting let me know eh?

Hi there folks!

First of all I know that this is a long time since someone has posted but here is my question.

When I was at uni I bought a HL-5250DN printer and used it quite a bit. The printer comes with the low yield TN-3130 cartridge. The printer began flashing the toner light then later on the printer stopped working. I needed to print stuff for uni and didn’t have time to look into it but I knew that there was toner left as the last page printed was top quality. I bought the high yield cartridge and it started printing again.

But out of curiosity I decided to put the old cartridge back in to see what happens and it started printing again! I got the status from the printer and it thought the high yield cartridge was still in there.

So my question is if I keep using the low yield until it is finished will I have a reduced use on the new high yield cartridge when I start to use it? I mean can the printer tell what type of cartridge is in it? (I guess it can so that it can guestimate the pages left?)

Regards

Dave:

I don't think there is any problem with swapping cartridges in and out....

by taping over the sensor holes in each end of my original cartridge I was able to extend the life by another 1000 pages. After that the background starts to "dust up" and get dark.....

But the printer is sensing how much toner is in the cartridge so swapping them should not be an issue....

I have the 5250DN and covering the eyes on both sides has helped me get a lot of extra life from the carts. I have NOT seen the "NO Toner" message, only the "LOW Toner" message...

I do not know, but perhaps the "no toner" message is generated differently -- i.e. low towner error is generated when the printer can see thru the cartridge via the eyes, but that NO toner is somehow generated differently .... page count or some firmware function?

Open the front cover and leave open while completing the following steps:
Turn the printer off.
Hold the 'go' button while turning the printer on. All panel lights should be on.
Release the 'go' button.
Press the 'go' button 2 times.

The toner light should be off.
The paper light should be on.
Close cover. The ready light should be the only light on.

these cartridges have a mechanicle reset on the side of the cartridge, once the cartridge is inserted in the machine the mechanicle reset is activated and will clear the toner empty message. so the only way to get the error is put a cartridge in the machine then take it out while its got toner in it then put another in then run that toner out, then put the first toner in and it wont reset the error message because the mechanicle reset has already been tripped. if that makes any sense.

the mechanicle reset can be reset by taking the side cover of the toner and put the cog back in its rightous place. that get triped once and doesnt gradually move it moves all the way when you first put the cartridge in .

Resetting the toner empty message on the Brother 4040-CN laser printer. I taped the sensor glass with electrical tape but that did not reset the "empty" sensor, this is a two stage process. There is a black cog wheel on the gear side. Looking at a new never installed cartridge will show you the position the cog pin should be on a brand new cartridge. The cog turns full cycle upon the very first install.

I discovered there is no need to even remove the cover held in place with two screws. I took a drywall screw (you could also use a tiny screw driver) and turned the cog counter clockwise. There is a tensioner spring that rides along the grooved sections of the cog, you don't have to turn it very far, only a quarter of a turn counter clockwise and then you will see the spring reposition and a pin will appear that you could not see before. If none of that makes sense and you need to have a better look then go ahead and remove the two screws and the cover, but once you see just how easy it really is then it will be a sinch the next time around, and don't forget the electrical tape over the sensor. - zpod

I tried the "tape over the hole" business and it didn't work for me.
Here's the technique for the MFC-7820N machine -- open front cover, push "options", push start, push 10, (mayber push "start" again here i dont remeber) then it should read "accepted", close cover, open cover, close cover, done. Haji, my technical support guy felt that I should not have had to open and close the cover a second time after it read "accepted", but I did.

Hey Waterboss thanks for your advice. I also have a MFC-7820N and following your instructions, after pushing 10, the "Accepted" message came up, DONE! In my case no further pressing or opening/closing was needed.
Great job you all here!

PS: Where have you found the best price for this machine's toners? - Anonymous
for a 7820N, I tried every trick, and the only one that works is this one, as Waterboss writes but here it is a little dressed up:

For MFC-7820N (using TN-350) displaying 'Toner Life End':
1. open front cover
2. while front cover is open and machine is on, push "options"
3. push start
4. (quickly) type in '1' then '0' (typing in "10") . if you are not quick enough in this step, start from the beginning
5. the machine says 'accepted'
6. toner goes and goes

it's odd that I had this problem shortly after using a replacement toner cartridge (real Brother) but a new 2nd party drum.. seems like Brother cuts up the toner too quickly because it works fine after this

Hi All
Anybody have a fix for TN250 cartridge in an MFC 6800.
Same problems with low toner light. Also out of toner caused shutdown. Managed to get it going again by cycling power on and off.
My problems have got worse after using after-market toner cartridges at ~$8 each but I can live with them (save $32 ).
Summary of my problems are
1 Toner shading intermittent. Sometimes gets worse as more copies are done. Sometimes starts bad and improves.
2 There is toner in cart and I would like to get low toner light off.
3 Occasional out of toner shutdown.

I have looked at the TN250, both brother and after-market, and see no window to cover!
Thanks for listening

I just purchased a Brother MFC-9840CDW. It uses the TN-110 (lo capacity) and TN-115 (hi capacity) toner cartridges. I only got a little over 1400 prints on the TN-110 black before it locked me out. I did look and found a little window, as described for other brother machines. I was able to put the tape over the hole in the toner cartridge tray (holds all 4) instead of putting it on the cartridge itself. It worked like a charm. I looked and there seemed to be lots of toner left. I just was able to make more prints with no degradation of quality. Thanks for the help. I will continue to use this to override the low toner signal so I can get maximum use of the toner.

Is there something else you guys with a MFC-9840CDW are doing to get the indicator to reset? I'm sure I'm covering up the right holes. Someone mentioned covering up the holes in the cartridge tray, I guess I can try that also, but if whoever has a MFC-9840CDW and gotten this trick to work could either email me at ([email protected]) or post back here, that would be great because now I'm getting a low toner indicator on all three of the color cartridges! Which makes me very suspicous. - bubernak
Exactly where is this window on the cartridge tray? My Brother MFC9840CDW is saying "Toner Life End" with new hi-capacity cartridges just installed.

Thanks Everyone - ladyolene
i put black tape over each of the four little holes on the tray, as suggested. but i am still getting the "low toner" warning on the LCD display. any other ideas? - unknown
I hope you can help me. I have a MFC9440CN and was giving me out of toner on black so I replaced with TN115bk and it works fine. Now it gives me all 3 colors need to replaced Cyan, Megenta and yellow. I taped 4 holes on the cartrige tray on all 4 (black,cyan,megenta & yellow) and still getting all 3 colors to replaced. Please help!!! Thanks in advance, Boone - Anonymous
Using Brother MFC 9840 CDW All In One color printer:

I tried covering the window on the right side of the cartridge where you can see the toner and covering the hole in the cartridge carrier tray that lines up with this cartridge window and the red light Toner At An End still lights up. then I covered the window hole in the left side of the cartridge and still get red light. Then tried replacing toner cartridge with a compatible cartridge in which I could see plenty of toner in it and I covered all the holes on each side of that cartridge too and still i get a red light and am locked out of printing.

I am obviously not covering the correct window or hole. I have watched U-tube and found that the round window on the cartridge is correct to cover but there must be more too it since i can see that i have otner in the compatible but Non-brother cartridges and there appears to be toner left in Brother ones too since so much on toner roller.

So the Brother color printer started pleading for a new set of colour toner carts ($270). All three carts ran out at the same time, hmm. Time for a Google, which unearthed the following on a blog.

Brother MFC 9440CN Toner Life End Message... The Final Solution!!!

1. With power on, open the toner access main door (You will get a "door open" message in the LCD.)
2. Hit the "Clear/Back" button and... ta-dah!!! you go right to the Toner Reset Menu' (cue Vienna Boy's choir sounds here).
3. Using the up ^ Down > "Search" arrow buttons, you can then scroll through reset options for each of the printer's [4] toner cartridges!
Code: B. = black; C. = cyan; M. = magenta and Y. = yellow
4. For each for these cartridges is the option to reset for low yield = S (small?) or High Yield = H
5. Using the number keypad, select option #1 (to reset each to the size you have installed.
6. Hit the "Clear/Back" button to get out of the menu, close door ad the problem is FINALLY solved.

Just tried it, works great!

I just spent an hour trying to find that "window" that everyone is talking about. Since you have the same printer as I do, would you mind helping me by telling me exactly where to put the tape on or even have a picture of it so I can settle this chaos in my printer?

thanks so much! - pearlbomb1

Works for the MFC 9440 CN also- there's a square "window" on the left side of the toner cartridge- I put a piece of masking tape over, colored it black, and it's printing again. I was getting a "end of toner" message.

Any chance of harming the printer? We have the MFC-9440cn on which I just replaced the original black toner with a high yield. I haven't replaced any color carts yet. The original black low yield gave me about 1600 pages. I'm wondering if I could try this procedure in a pinch without endangering the printer. (it's an office printer, can't take chances)

Thanks,

My low TONER (color) light came back on again. Searched the internet and found this solution and it worked also for my MFC-9840CDW. You will see after the color an S or H, for small and H Yield. I did the all. After the door open sign came back on I just closed the door. Printed this email, no more LOW TONER message.

Brother MFC 9440CN Toner Life End Message... The Final Solution!!!

Having gratefully read about how to defeat the toner sensor window with black electrical tape, I went to work.
Sadly, I was crushed to discover that performing this operation did not solve the problem for my accursed unit.
[Do it anyway as it will save you from these annoyingly premature warnings in future!]

Reading further, I became convinced that a reset process similar to that used to solve this problem for the Brother 2040 and 7420 models was also required here.

With nothing more to go on than responses to my emails from the good people (knuckleheads) at Brother telling me only how to install a new cartridge, I began poking around on my own 'till, after much swearing and gnashing of teeth, I figured it out:

1. With power on, open the toner access main door (You will get a "door open" message in the LCD.)
2. Hit the "Clear/Back" button and... ta-dah!!! you go right to the “Toner Reset Menu” (cue Vienna Boy's choir sounds here).
3. Using the up ^ Down > "Search" arrow buttons, you can then scroll through reset options for each of the printer's [4] toner cartridges!

4. For each for these cartridges is the option to reset for low yield = S (small?) or High Yield = H
5. Using the number keypad, select option #1 (to reset each to the size you have installed.
6. Hit the "Clear/Back" button to get out of the menu, close door ad the problem is FINALLY solved.

Thanks for the tip, I have a 9840, but will have to try it to see if it works on mine as well. Does the 9440 use the TN-110/TN-115 toner cartridges? I too was unsuccessful with black electrical tape, but was able to get rid of the "low toner" warning and continue to use my old cartridges by removing one of the end pieces and resetting one of the gears, but this certainly sounds like a simpler solution!
by bubernak on Jun 30, 2008 at 12:41pm Add comment
@buber...
Yes indeed... same cartridges.
I too looked at that link and had images of toner flying everywhere. Was pretty sure there was a simpler solution.

Oh, one more thing I meant to add about saving toner in the first place: you might want to try turning on the "Toner Save Mode" to stretch out your cartridge replacements.
Open Printers > go to your printer's icon > Printing Preferences...> Advanced Settings > select "Printer Functions" (far right icon) > select Toner Save Mode from menu >> turn "on".
Results look fine to me for daily use, though not suggested for grayscale or photo printing.

Best,

There is a class action regarding this very thing. Are you still a ca. Resident.? - Lance43
Thanks Very Much!

This worked for me using the HL-2040 with a single black tape over the clear plastic sensor hole on the non-gear side. Just printed my first (post out of toner light) page.

If this gets me another 500 pages I will be grinning because this is just the starter (half full) cartridge that came with it when I bought it.

Also I'm glad the solution is all hardware. I was worried it would be a software patch and since I'm using linux and most people windoze it wouldn't be easy. Great website, real need for this sort of thing!

Does anyone know about printers that just have a toner bottle you refill the supply yourself? Then you just buy bulk toner. I have this Toshiba photocopier from 1987 also that got great milage that way. I guess it doesn't fit the consumable cash cow business model though I bet anybody to offer a printer like that would have legions of loyal customers right away.

Best write up I have ever seen on this subject, thanks to all for the information, great job. Be nice if Brother would just publish all the information and tell us what is going on.
Love the Brother printers, almost no paper jams. Have been using them from the HL-1240 thru the 1440, 5250DN, MFC-8660DN printers thru the years. Have bought at least 16 Brothers printers, love the low cost per copy. Watch for the printers on sale, new printers on sale are cheaper than buying replacement drums.
Reasonable quality paper helps, 22lb or 24lb works a little better than 20lb paper. 16lb paper works but don't use it except when required for special jobs.
Thanks to all.

Yay! It works! I have a Brother MFC-9840CDW that I just got last week. Had printed 650+ copies (about 2/3 black, the rest in color) when the black "low toner" started coming on. And then the dreaded "toner life ended".

Took me a bit to get it to work, and I'm still not sure which "hole" I was supposed to cover up. I ended up putting small pieces of duct tape over 3 different possible "holes". The first time I tried it with scotch tape over the square "window" and black-sharpied over that, but it didn't do anything. So, either I had the wrong spot or it needed something more solid like the duct tape.

Still, if someone who has done this successfully could clarify which place exactly needs to be taped over, that will make it easier for me to do the color cartridges when they start saying "low toner" too.

Thanks in advance! So happy I found this fix, thanks to the person on Amazon who shared this link in his review of the printer. And happy that it worked!

I have a MFC-7220 which uses the TN-350 toner

I had a "End of toner life" message.

I covered up the reader holes. This did not work.

There is a "reset gear" you need to "flop over" for it to think there's a new toner in...You may need to roll the big black roller for it to move freely...

Here is link to a picture of what the gear looks like. It does not come with "starter" cartrages...

Hello ppl, I had just solved my problem, when my Brother laser printer DCP-7010 was started showing toner life end. So u ppl do two things. 1. Stick the black electrical tape over the two eyes of your printer sensor, which detect cartridge toner inside.
2. And again move ur cartridge gear like white button to the circular left side. This can be easily done by opening cartridge
left side small cover. - Anonymous
I've been using a combination of these procedures since I got my MFC-9840CDW printer a couple weeks ago. A few things to note. Even after putting tape over the sensor hole on the left, I sometimes still have gotten the low toner message later on, even when the output still looks fine. I covered the hole on the right (the plastic one) to get more life out of the cartridge. Taking the cartridge out and shaking it a bit sometimes helps too.

To answer the question above about whether this is worth the trouble, to me it certainly is because I now switch cartridges when the output shows me that the toner is running out -- not when some message tells me to do it! The additional number of prints you can get from this method will vary depending on how much coverage there is on your page. I have gotten at least 500 more prints since the first "toner low" message came on, and I have been printing almost full-page prints.

I do suggest changing to "toner save" mode if you're printing something that doesn't have to be at the very highest quality. It basically just prints lighter.

One thing I will say about this printer regarding the comments I've read about "it's just like having a Kinko's in your own office/home." Well, it is... and it isn't. The "cost-per-page" that I've read for this printer is something like 12 cents/page. Sounds much better than Kinko's, Staples, Office Depot (they all run from 29-49 cents/page on sale), right?

The problem is that the estimated pages-per-cartridge is based on an "industry standard" of 5\% coverage. A Brother CSR explained to me that would be like a 1-inch solid square per page. Well, who prints that?! I am printing full-page, full-color flyers. And there's the difference -- if I print/copy these at Kinko's, I pay the same price whether every inch of the page is covered in color, or only one inch is.

I like the convenience of having this printer at home. Cost-wise, though, I most likely could save some money going to Kinko's. Especially for full-color, big jobs. As quickly as I've gone through toner (even using all the tricks I learned on this forum, which have helped a lot, and even after finding the least expensive place to buy toner online -- Provantage dot com), I would guess it's costing me about 25-35 cents/page. I have not been using the "toner save" though -- hopefully I can reduce the cost by using that more.

A quick analysis here...

I print very basic text pages and am getting around 3300+ pages per toner.

A Toner being about $63.00ea for 3300 prints and a drum being about $102.00 for 15k+ prints works out to about 2.6 cents per print.

Divide the cost of the printer ($150.00) by the number of total prints I have on it so far (24k) and my TOTAL print cost works out to about 3.2 cents per print. And that's if the printer craps out at 24k prints. The longer it goes, the cheaper they get)

Of course you'd have to figure in electricity costs too, which would actually be pretty negligable at about $0.00006 per print. ($0.08 per KillowattHour / 1,200 PrintsPerHour) (The manual tells me that the printer peaks at 1k watts. This figure assumes it's peaking for the entire hour)

Getting the extra 500 or so prints out of each cartradge and you could possibly get your print costs down to about 2.8 cents per print which, at this point, would have already translated into $96.00 for me so far...If this printe makess it to 37k prints it will have paid for the cost of another printer...totally worth the 5 minutes it takes to put tape over the holes...Thanks guys. - Anonymous
That's an excellent analysis.

by jaredtrice on Aug 22, 2008 at 11:00am Add comment
jaredtrice,

I'm also curious if I can find a similar fix for my (second) MFC-3360C multi-function unit. My first worked great for a couple years, then started spitting pages out half-printed. Paper-feed trigger wasn't damaged. Nearest service site is 3 hours away, so I only talked with a printer tech there over the phone and he admitted he hadn't a clue why it might be doing that.

So I bought another one, they are cheap after all. Next one showed up, I swapped the previously just fine printer cartridges, but the new printer error message read "no cartridge installed". So I popped brand new, out of the package ones in, and it read the same thing. Brother's service said that occasionally happened with "non-Brother" brand cartridges, but never seemed to be a problem with Brother cartridges.

I paid the UPS rate to send it to the service site. The tech called a few days later to say the problem was fixed, but the cartridges I sent were "bad", and since they didn't want to pay for cartidges themselves did I want to buy them so he could verify that it was fixed? No.

So it's on its way back to me and I have little doubt it isn't going to work.

But looking at the cartridges, I notice there's a kind of indented, clear-plastic block-window that shows ink level. When my printer comes back I'm going to explore how to black this out and see if that helps...if it's just a cartridge sensor problem.

Very much Appreciate the article! It's actually pretty unsettling the company managers often feel it's ok to scam their customers for profit. I'm sure they tell themselves it's no big deal, and go home to their family's and civic clubs and such and think they're perfectly wonderful people. But the reality is that doing dishonest, scammy things means you're basically a dishonest, scammy person. Or company.

I buy bulk ink from printersink.com and inject it into the supposedly depleted cartridge...have not figured what that cost is per but WAY less than buying brand name ones. I still would like to know if there is a trick to your 440...I take it that it is and injet printer like my 420. Anyway nice to have ways to get around the ungodly cost of cartridges. - Anonymous

If you are using an aftermarket cartridge without the sensor window make sure the tab on the side is facing approximately 10am and not 3pm. Many of the Brother models are finnicky on a cartridge replacement. I always 1. unplug the Brother. 2. Take out cartridge. 3. Put new cartridge in but leave the door open. 4. Plug in machine and close door.


Seems to work most of the time

I want to override toner replacement on a Brother laser HL1400. Anyone know a semi-permanent technique such as the electrical-tape-over for my machine? I used a page reset code, but it's a pain to do it every time I want to print. I don't see an eye or a white switch that is mentioned on other Brothers. Here's the page count reset I'm using if anyone wants it:
1. Open the front cover and leave open while completing the following steps.
2. Turn the printer off.
3. Hold the 'go' button while turning the printer on. All panel lights should be on.
4. Release the 'go' button.
5. Press the 'go' button 2 times.
6. Pause.
7. Press the 'go' button 5 times.
8. The toner light should be off.
9. The paper light should be on or flashing.
10. Close cover. The ready light should be the only light on.

For the HL series:

3 press the reprint button while still holding cancel
- here is the reset menu - go to the appropriate cartridge on
- the menu and reset it and you're done!

look for a clear round plastic piece on the side of the toner cartridge (on mine it is on both sides i dont know if it is the same on all) everything else will be black plastic and this will be clear - you should be able to see the actual color of the toner through this clear round plastic part if there is any toner in there and its not empty (which is why were all here) - like this... if it is the cyan cartridge you should be able to see blue powder through this clear part on the side, if its yellow cartridge you should see yellow powder and so on - tilt the cartridge back and forth and look at the side to watch for the powder (toner) to cover up the clear hole when you tilt it that way - i took electric tape and put it right over this part on both sides then magically (after turning the printer off and on) I could print - from looking at pics of different laser toner cartridges online, they all look to be pretty similar so I would think this would be pretty close to accurate for most of them - the HL 4040 that i have uses the TN115 cartridges or the high yield version.
i think it only matters if you cover a "window" on one side of the cartridge though - according to what i read a light is sent all the way through the cartridge and if it is "sensed" on the other side it "thinks" the cartridge is empty - so covering up the "window" on either side of the cartridge will block the light from making it through

tried your black electrical tape trick on mine under the same circumstances.. removed the cartridge and placed small pieces of elec tape over small circular holes on either side of the cartridge holder, rather than the cartridge itself. Alarm buttons went off immediately and it is printing up a storm.

thanks much guys.

Hi,

OK, have a Brother 5250DN, Toner light on, although filled cartridge in printer.
Will refuse printing.

Covered all sensor holes, that did not help.

Put a brand-new cartridge in, now all is fine, light is off, printing goes again.

And then , here the trick: put the other cartridge back in -> voila, now it works.
Not sure if I understand this one, but hey, it worked for me!

enjoy the cartridge ride . .

Could you tell me where the sensor hole is - what does it look like? I don't see it anywhere. Do I take the toner out of the drum - it is on the toner cartridge or drum? Would red duct tape work or does it have to be black?

Warning! Please read this remark carefully.
People in this forum have found out all kind of tricks to override “toner empty/toner end of live messages”. The reason you still can print with an almost empty cartridge is a mechanical one. The remaining toner prevents possible mechanical problems. In other words, the remaining toner has a smearing function, it works like “oil” in the toner cartridge. There is a possibilty that the tonercartridge stops turning around in case of covering both "eyes". As a possible result, the toner drive gears inside the machine all will be destroyed! End of machine live!! Another reason is to prevent leakage of the toner unit. The developer roller has mechanical limits and its developed for a certain amount of cycles. Conclusion: there is no commercial reason for Brother, but just to prevent mechanical problems.

I'm very skeptical of your defense of Brother with slanted wording about following the "tricks" on this forum. You say "tricks" to devalue the practical advice for people who desperately need it. For me, as I'm sure it is for others, having to replace the color cartridges at the rate the printer specifies is cost prohibitive, mechanical failure notwithstanding. So the choice becomes either to follow the advice on this forum or to throw out my Brother printer and buy one more affordable to maintain. I'm guessing that following the advice to reset page counters for toner usage would greatly benefit the pocketbooks for those who need it, at the expense of Brother's revenue. Perhaps that is the real justification for your so-called warning. - mzinn
A bold, dire, warning given without any supporting authority; provide us with your source or be deemed a shill for Brother or one of its ink suppliers.
Besides, if it's destroyed, it'd be just as cheap to buy another, perhaps non-Brother, printer.

I have no idea how to find the sensor on my machine to black out with a marker or tape to get more prints. also, my drum is bad after owning the machine 6 months! I called staples where I bought it and the extended warranty of course (which i was assured would cover everything) and of course the drum isn't covered. They want to charge me $159.00 for a new drum. Please please please give me detailed instructions on how I can extend my ink and fix this drum issue.

my faxes are coming out with a black line on the left side of every page.

MFC-240C


the "hole" you need is on each individual ink cartridge. On the end where the ink is supplied, you have to marker out the clear plastic ink cartridge on the face, and both inner-sides -AND- you need to mark out the cartridge itself where that clear ink cartridge can be seen (thinner plastic and the light travels through it, you can see if you hold it up to a light) on BOTH sides of the cartridge.


Then put all cartridges back in and respond YES to the prompt on printer "did you replace".


Ta-da!!

see my post about resetting the flag gear. its very simple. - davagain
I am so pissed with brother....I have been spending $1000's each month in our office on ink for the Brother 9840cdw. Overall this is a fantastic printer no paper jams or any problems. My grip is that we kept getting toner end life after short periods of time. I only use hi yield printer ink (original manufacture) but seemed to be going through the ink rapidly.
Finally I had had enough, I changed the toner before Christmas and now we are into first week of February and its asking to replace Yellow ink again, issue is our office hasn't been even been open most of January and we have had little use of printer let alone colour. But today i get the low toner message and so i pop the cap and check if its empty, cause it still feels full. Shock and Horror it is still full, i pour the remaining well over half the yellow toner into the trash. Man I am angry- then I google and find this forum and find the "hidden" reset menu for the toner and low and behold they all work... I kept a few "empty" cartridges aside cause I felt there must be something wrong with my printer, but now I know there ISN'T...because I know that Brother has been ripping me off BLIND.

And to the anon forum poster who thinks you need half a toner cartridge for "lubricating" the mechanical parts, that is complete CRAP!!! There is way to much left over toner for that excuse... Where do u get your insider knowledge/propaganda from??

For anyone who hasn't read the Forum tip:

step 1. Pull open front toner bay

step 2. press back button

step 3. reset toners

I finally resolved this problem on my HL-2040 by resetting the "toner empty" mechanical flag on the side of the cartridge. I had to remove three screws to remove the plate that covers the gearing, and then manually move a white plastic gear about 90 degrees counter clockwise so that indicator "arm" was pointing to about 10'oclock (it was at 3 o'clock before adjusting it). The whole procedure took about 5 minutes.

Many thanks to all who posted their tips.

Love it!

Just did the scotch tape / sharpie thing with TN-330 cartridge for my HQ 1200 printer. I'm not mechanical at all but I figured it out pretty easily.

Here are the instuctions for mechanically challenged people like me:

The holes that have to be covered are on the narrow sides of the cartridge, where the ears would be. One on each side, perfectly round, about 20\% smaller than a dime. I took 2 pieces of scotch tape, ripped 2 small pieces of paper, colored them black with a Sharpie, stuck one to the center of each piece of tape, and taped them inside the holes. I colored the outside of the scotch tape too for good measure.

Voila! Printing again.

Ha! I love this. - Anonymous
Big Brother wants us to buy toner before we need it. My Sharpie wasn't flexible enough in the HL-2170 window, but I happened to have a craft store .5 mm permanent pen that did the trick. Thanks!

Some brother cartridges use what is called a "flag gear". The gear turns slowly every time the cartridge is used. When it gets to the end of its range, a spring stops it from turning further and the printer will not print until the cartridge is replaced. When a cartridge is refilled, this flag gear must be reset or printer will think the cartridge is still empty and it will not work. You can also squeeze some extra life out of a used cartridge using this method. Caution: in cartridges that have a built-in waste toner reservoir, resetting the flag gear can result in continuing to print when the reservoir is full and spilling waste toner into your printer. This can ruin your printer, so be careful. In printers that have a separate waste toner receptacle, this is not an issue.

I just had this flag gear issue on a MFC-9840CDW, so I am going to give instructions for that cartridge.

1. Orient cartridge so that you are looking at the end of the cartridge with the developer roller to your left. (This is the opposite end from the filler cap). You should see 2 phillips head screws, one at the top right, one at the bottom left. You should also see part of the gray flag gear through an opening in the end cap.

2. Remove screws and the end cap they were holding in place (one or 2 gears may fall out when you do this, but they should be simple to pop back into place).

3. Note attachment point of the spring over flag gear, then temporarily remove it so you can reset the gear.

4. Remove the flag gear and reinstall it so that its teeth are just beginning to mesh with the adjoining gear.

5. Reinstall the spring.

6. Reinstall the end cap.

DONE

This is MUCH easier to do than to describe, like tying your shoelaces. Once you have done it and know what to look for, the entire process should take less than 1 minute.

So this was a well-known issue on Brother laser printers... I was actually waiting for my HL-4070CDW to be delivered, and when I learned about this premature toner disposal issue, I had felt a distant sense of alarm. I had chosen this model over the Hewlett Packard CP1518ni mainly because they said hp's CP1518ni toner wore off much faster, so I had thought Brother would come up more economic in the long end.

When somebody pointed out, "How come all the three color toners can wear off at the same time?" my first reaction was like, "What?!"

Anyway, thanks for all the valuable information, guys. Now I think I can stop worrying about whether to return this to the retailer. :-)
by peacenet on Oct 26, 2008 at 9:42pm Add comment
I noticed many people are stating on here about all three color toners being empty at exactly the same time. Just to clarify this, if you are paying attention to what the LCD display says, it tells you which toner cartridge is about to run out or which one is at the end of it's life. The LCD display then changes to red and hults all actions of the machine from printing. It DOESN'T mean that all toner cartidges are empty, it is just an electronic setting to hault any further printing when the machine detects that a cartridge is at the end of it's life. I am hoping I can try some of the "tricks" listed here for myself and get results. Thanks guys. - Anonymous

I have a Brother MFC 9840CDW. I first got the Toner Low and then the Toner Life End message. After reading the various responses on this blog, I did the following to re-set the printer:

1. Turn on the printer

2. Push the button on the front of the printer to open the cartridge door. Don't remove the cartridges.

3. Push the Clear/Back button to bring up a reset menu. There are 8 different toner functions (for simplicity, two B's, two C's, two M's, and two Y's).

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.

My Brother MFC-9840CDW was driving me CRAZY with saying Toner End when I'd hardly printed any color text at all. Wasting my $$$ and my time driving to Staples, heating up the environment by so doing, all the beeping, and mostly not being able to print at night when I work (and Staples is closed) was getting me close to buying a second printer (NOT a Brother, obviously...).

Hopefully the resetting, and actually running the cartridge till the toner really is done, won't harm the printer; I love it otherwise. - unknown
I don't have the 4070cdw model, so it might be different than the 9840cdw. But, after the 'door open' message was displayed, I simply pushed the clear/back button to go back to the reset menu. The 'door open message the disappeared. If that doesn't work, try experimenting with variations of those commands. Most of the Brother printers have a software option for resetting toner settings. You don't need to do a mechanical ('tape') solution to reset the false toner messages.

i have seen this problem before
when you open the front cover on left hand side there should be a black arm that latches onto the cover make sure that is connected if it isn't it has probably been pulled back into the side of the printer
if you can see the arm just sticking out of its hole, pull it out , if it wont come out any further that means the pivot gear is broken this is cause mostly by recycled and compatible toner cartridges

this arm controls the gear that engages the toner cartridge so it the toner cart has siezed it with snap the gears

as i recommend to every one even tho brother cartridges are expensive they always produce the best quality, and wile hte compatible brands are cheap they are the number one cause for quality and structural issues - Anonymous

I have a Brother MFC-420CN, the one with four colors. All of the colors, Black, Yellow, Blue, are fine, except I received a LED notice that the Magenta was “NEAR EMPTY” (which it was not). I replaced it with a brand new cartridge, and now the LED message reads, “NO CARTRIDGE". I even went and purchased another brand new Magenta cartridge thinking that the other was defected, and this one - same thing. I just cannot get this LED display or the Brother machine to READ that there is a new cartridge in there. I called an authorized dealer, and he told me it may be the sensor...and to fix it, repair costs begins at $55.00+parts. I have unplugged the printer, turned it on/off, took all the cartridges out, then placed them all back in following the LED instructions, then answered YES when LED asked if it was replaced...I have even placed the wrong color cartridge into the Magenta slot, and it still does not read that there is a cartridge in there.

dude this is the best. for the HL-4070CDW. just cover the holes on the right side of the tray. if you are pulling the tray out, the right is on the right of course. the little holes that allow the 'sensor' to show through. just cover them up with tape or I used a torn off sticky pad, covered with scotch tape.

I 'ran out of yellow' covered that up, now its OK. if you look at the printer's configuration by using a webpage, I saw that Cyan was also 'low' stuck paper over that is gone. I mean the yellow had so much toner left it was sloshing around the inside. now we can run the toner out and see how much it really has!

MFC-9840cdw. First many thanks to those who posted - especially tsatiyeh.

Printer stopped due to no toner (print quality was fine). I used the black tape method frequently mentioned. Printer then worked but I kept getting an annoying "LOW TONER" message. tsatiyeh described a reset on another model - see that post.

Here's what I want to add to the discussion. On the MFC-9840cdw: To get to the reset options that tsatiyeh describes:
1) open the door as if you were going to change the toners
2) press the Clear/Back button
3) The Reset Menu appears!
4) I reset all of the TNR-S (four of them - one for each color)
5) all is well

For the 7820N, I ran into the TONER LIFE END message numerous times.
I have used the trick whereby you open the front, press options, then 1-0 and start. This would buy me some time, but not much.

When I pulled the drum and toner out, I noticed a clear circular window on the right side of the device. Figuring this was the "sensor" that was causing my printer to want more expensive toner, I covered it with tape.

I pushed the toner / drum back in and it works perfectly. No warnings, no quality issues.

The brother hl-2170W has been a real POS for us for the most part. Wireless is spotty, support was bad, etc. When the low toner light came on only 350 sheets into the cartridge (when at 328, I'd seen it say it had more than 80\% toner left on a setup page) I was ready to heave it out the window.

Found this thread. On the 2170, pull the black carrier and gray cartridge assembly out together. Remove the gray cartridge assembly. on the right side (as you removed it) there's a little clear plastic window. that's the thing to cover.

I used masking tape then colored it with a not particularly black marker. Still printing...

Just recently got toner low warnings on all cartridges for Brother MFC 9440CN, so when I checked cost of replacement cartridges I was horrified.
So I bought 4 refill bottles which cost a ridiculous $190, $47 each for 130g of toner which must cost about $1 to manufacture.
On reading instructions it said you must empty cartridge of old toner before refilling as new toner may not be compatible with old toner and cause a chemical reaction.
I pulled plug from refill hole and tipped over trash can and expected about one spoonful of powder to come out.
The ceiling fan was on full and the next thing I knew the whole room was full of toner, MORE toner came out of the supposedly EMPTY cartridge than was in the refill bottle.
What a friggin con. These printer makers obviously set the warning way early to get you to buy more cartridges. It's a disgrace.
I have now used the information on this forum from "Brett In SoCal (posted 6/29/08 4:57 PM), see above, which has worked a treat. Don't ya just love genius's - thanks Bret you're a star.

LOL...I know what you mean! I also purchased toner refill for my Brother DCP 7020, and as you stated the instructions said "you MUST empty the cartridge of old toner before refilling." So, like you, I turned it up over the garbage can expecting a very small amount to come out and .....HOLY COW!! Like you said, I think there was more toner left inside my supposedly "empty" cartridge than there was in the refill bottle!

Had I known that beforehand, I would have emptied it into a container and recycled it back into my cartridge the next time.

Thanks for the laugh though, the bit about the ceiling fan cracked me up! When I was working on mine, my 3 year-old little girl kept saying, "Uh-oh! You make-a-de-mess!" LOL It really does go everywhere, so be careful guys, and wear old clothes. - Anonymous
Update to [Brother MFC 9440CN Toner Life End Message... The Final Solution!!! ]

When last we spoke, I had just reset the counters on all 3 color cartridges using the technique posted in my comment of (6-29-08)
Simultaneously, I decided to enable the printer's "toner save mode" as the savings have proved well worth the minor degradation in print quality doing so causes.

Cut to now... I have just done enough printing to receive another "Low Color Toner" warning... with, of course, no actual end of toner in sight!
It had been so long, I had to go back to my earlier posting to remind myself what to do. The good news is that it again worked perfectly.

Doing so suggested this tip: regardless of what size cartridges you are using, reset each color's counter to the "H-high" setting as the point here is that we are waiting for the PRINTS to tell us when a cartridge really needs replacement... not our beloved machine's bogus counters!

Cheers!

Hi there:

I actually replaced the toner cartridge. Used the exact same steps (open cover, hit clear/back butten, reset the black toner by pressing "1", and get out again).

But the "Toner Life End" message is still there!!! What's wrong with my printer?

Thanks for any advice.

This is my post from August... I have seen it worked with 4070 as well as the 4040 that I have... I know it can get a little hard to scroll through this whole page looking for this stuff.
Re: Brother toner cartridge low toner override by hagan (8/22/08 2:21 PM) reply + / -
since i finally figured this out I thought I would post this for anyone who has the
HL-4040 CN printer - or one similar
After seeing the hitting the buttons with the door open tricks for different models I tried anything that sounded like it had the same buttons my 4040 has... nothing on here worked so I just started hitting combinations of buttons with the door open - wow there are quite a few hidden menus there

For the toner life reset menu:
1 Open the front cover of the printer
2 press and hold the cancel button
3 press the reprint button WHILE still holding cancel
- here is the reset menu - go to the appropriate cartridge on
- the menu and reset it and you're done!
FYI... Pressing the "Go" button and the up arrow gives you the parts life reset menu (drum, laser, fuser, etc.)

I'm so happy I found this forum. I use a TN-350 toner and it died out on me at 2400 pages (and I just got it last year). I was *about* to go out and buy a new toner but then I thought "Why not go online and try to find a solution?".

This was the third website I found about fixing a toner. Like this one and many others, it told me to cover the clear plastic holes. But that didn't work for me. I was getting frustrated cause it seemed to work on everyone else's printer. But then later I used the reset method (mentioned above), and it worked!

And I'm soooo happy cause I know I will get a couple more hundred pages with my toner.

I can't believe Brother would do this to us =(

One more big thumbs-up for this fix. Can't find my manual for my 5170DNLT and the brother support site is down -- so I wasn't sure of the meaning of the "dumb" status lights. Not knowing whether this was a serious problem or simply low toner, I did not want to invest $90 in a new cartridge to find out.

Tried everything else including the corona wire and high voltage contact cleanings to no avail. Found this page, put some electrical tape over the sensor hole and Voila! It's printing again! Now I know my printer's still good, and am confident making the investment in a new cartridge when the toner does run out. Thanks everyone!

If I'm reading these postings correctly, it seems the HL-4040CN problem can be solved by EITHER blocking the toner detection windows on the cartridge, OR using the toner life reset procedure, or manually resetting the cartridge reset gear. Do all of these procedures solve the problem, or is one better/easier than another? It seems like any of these 3 detection schemes could/would override the others. What am I missing here? Thanks for your help.

I feel your anger, jwooden5941 but it ain't just Brother. Practically all printer manufacturers do this sort of stuff. Printer ink/toner is BIG business.

DCP 350C worked! Thanks for sharing. We don't EVEN USE the color ink, so we were trying to figure out how it was empty to begin with.

Of course, as we did this, each sucessive color cartridge showed "empty." Changed cyan, next message, magenta out, changed magenta, next message yellow LOW. That would have been HUGELY annoying if I were running back and forth to the store with one cartridge at a time.

Be prepared to tape them ALL up.
by Anonymous on Feb 18, 2009 at 11:10am Add comment
Well, I'm yet to try the "reset gear" method but using tape to cover the toner detection window works better for me than resetting the cartridge via the control panel.

Whereas resetting the cartridge via the control panel only allows one sheet to print before the LCD reverts to the rather annoying "Toner Life End" message, thus far taping the window has allowed printing of several sheets in succession with no indication that the toner is even getting low. (My printer is the same as yours: HL-4040CN.)

These postings are great... I have a Ricoh printer that also stopped printing due to toner. I found this forum while searching for an answer, and decided to take a look at my cartridges.

Thanks for the comeback. It seems like the tape method is the most popular, so I'll stick with that simple solution. For those wondering why manufacturers use a system that encourages cartridge replacement, consider this.....My Brother HL-4040CN cost $199 on sale at Staples. It came with 4 cartridges, that cost $60+ each ($240+). Bottom line, they gave me the printer and $40 to get me on board to purchase as many cartridges as possible. Their business model is to sell as many printers as possible, even at a loss, so they can sell lots of highly profitable toner cartridges. Thank goodness for forums like this, and black electrical tape! Good luck.

Someone explain this, please...I bought a 9840CDW 2 months ago.
So far I probably printed 100 BW text pages and another 100 or so CD color labels and CD color booklets.

Yesterday I had my first big run: 50 full color duplex flyers with an image size of 7x9 inches on the 8.5x11 area.

I checked the toner levels prior to starting. and all 4 colors were as full as the first day of use.
After the first 50 pages came out, I sent the comand to print another 50 pages, and in the print dialog box I got a "Low Toner" warning message.

I checked the levels, and all were still full as the first day, except for the magenta toner which showed up as 90\% empty! The image was not a 7x9 solid magenta block; it is an outdoor garden image with some text floating on top of the image on one side and a light clouds with more text on the other side.

I'm aware of the 5\% yield theory and I read about the black tape trick and the software cartridge reset but, come on! Aren't these fixes a little premature in my case? I only printed 50 duplex pages!

Are the factory installed cartridges so small? Why didn't the other 3 toners show no change at all?

Any clues anyone please?

I tried the fix cited here for the 4070 cdw and it worked!!! Thanks so much. I like the printer fairly well, but am very frustrated that it requires all of the colored cartridges be replaced at the same time. It happend twice within 4 months and at $50-$88/cartridge for four cartridges, i'm considering a different printer. Is this typical for this machine? Why would all the cartridges empty at exactly the same time?

by annemariesimpson@hot on Mar 13, 2009 at 8:56am Add comment
A couple things to bear in mind if using the "cover the hole" method:

Make sure that tape or whatever you use to cover the hole is SECURELY IN PLACE. Otherwise if it comes off and gets into the works of the printer, you might have to call a technician and be left with a BIG repair bill. A good alternative to tape is Cling brand floral clay; It's VERY sticky and once applied, is sure to remain in place until you deliberately remove it. It's a bit pricey but worth it, IMO.

Also, closely monitor print quality and at the first sign of that color (coming from the cartridge you modified) going, replace the cartridge. Failing to do so can shorten the life of your printer.

Thanks for the post, it was very helpful. I have tried this with the TN-110 cartridges/HL-4070CDW and it works perfectly. I believe that once the printer detects the low toner optically, it goes to a page count to determine when it thinks the toner is empty. I have not taped it, as I still intend to buy a new cartridge, but this should last a while anyway.

That doesn't sound good. The documentation supplied with my HL-4040CN states: "If the printer becomes hot, blows smoke, or generates an obscure odor, immediately turn off the power
switch and unplug the printer from the AC power outlet. Call your Brother dealer or Brother Customer Service."

With my HL-4040 CN I quickly got an intermittent "low toner" signal on the LCD display for the _magenta_ toner. This was weird, as I was printing lots of black, with some yellow, and only a little bit of red or blue.
Then without warning (that I noticed), I got a "toner life end" error message on the LCD panel for the _black_ toner, and couldn't print. I'd already bought a replacement black (high-capacity), because I knew I was going to be doing a lot of printing. Well, I was originally quite happy, because I got almost 3000 pages out of the black toner cartridge shipped with the new printer, which was over the design specification. But I was surprised, considering that the print quality seemed fine.
After replacing the black, and more printing, I got the "low toner" signal steadily for the magenta, and then suddenly (at the same time) for magenta and cyan too. After a few hundred more pages I got the "toner end life" on all three simultaneously. This was definitely fishy. Thanks to this forum I am on the way to fixing this. The tape didn't work (I used masking tape, and didn't try very hard). But the toner reset on the hidden menu has helped.

Hi all,

Works on HL-4050CDN as well, and like the previous poster, repeated here to save hunting all over the page for the routine:

For the toner life reset menu:
1 Open the front cover of the printer
2 press and hold the cancel button
3 press the reprint button WHILE still holding cancel
- here is the reset menu - go to the appropriate cartridge on
- the menu and reset it and you're done!
FYI... Pressing the "Go" button and the up arrow gives you the parts life reset menu (drum, laser, fuser, etc.)

I'm guessing that the abbreviations are:

B.TNR-S means black, toner, standard (next option is B.TNR-H which I assumed meant High (capacity) but if anyone knows different I'd like to know.

Thank you thank you thank you posters, I reckon you just saved me a couple of hundred quids a year.

by Pete H on Apr 29, 2009 at 6:53pm Add comment
Here's what I think about which method works best...
There seems to be a standard number of pages when the printer "thinks" the toner is empty and wants you to refill.
This is when I would use the control panel reset instructions.
then...
As far as covering the windows, it seems that the printer "thinks" the cartridges are empty when the toner falls below a certain level. As we all know, that level is like 3/4 full so blocking the windows with tape makes the printer "think" that the cartridge is still full of toner since the laser (or whatever it is) cant shine through to the other side. I would try this if resetting the toner life in the control panel doesn't get you printing. Next time I replace cartirdges (when it's REALLY needed) I plan on putting the tape on the window to start just to get it done!

I haven't ever done anything with resetting the gear, and as you can see from my last post, I am on my 3rd reset of the toner life in the control panel. To me that seems like it might be a little too much drama when the other methods are already doing the job (for me).

by Anonymous on May 11, 2009 at 3:42pm Add comment
I have a Brother HL4070 and have gone through 3 sets of toner cartridges; so have spent 3X the cost of the printer on toner alone! It was 11:00 pm and my highschool junior was printing his presentation for tommorow's class when the yellow cartridge "ran out". Out of shear desperation, I searched for a solution, and came upon this forum.

I found the above post particularly helpful, especially the link to the excelent article on remanufacturing the cartridge [http://www.uninetimaging.com I did try covering the sensor hole, but no luck, still complained about "empty toner", but I could see quite a bit of toner inside my yellow cartridge (TN115Y). So tried the "resseting the gear" suggestion, and worked like a charm! You do NOT have to dismantle the cartridge, or even remove the end plate. A ballpoint pen inserted through the gap is enough to slide the gear back on the spring to the "full" position. Printer is working fine without any complaints.

PS: The smell from the Brother printers is supposedly the smell of Ozone, due to the materials used in the toner, and heat. According to Brother, it is not a "dangerous" amount. As a precaution I have networked the printer and moved it to our family room, and away from the bedrooms upstairs.

I rather like the smell. Besides, ozone is actually good for you. As a matter of fact, we have a clinic in Barbados that offers ozone therapy for all sorts of maladies and some clients have reported amazing results!

BTW, for those wondering if the yellow cartridge whose sensor hole I covered some time ago still has toner - it certainly does! There has been no degradation in print quality whatsoever. And I've printed quite a bit since covering that hole.

Last December "Anonymous" posted the following. None of the steps to put tape over various holes and eyes worked on my Brother HL-2140, but the following from "Anonymous" did work for me.

Re: Brother toner cartridge low toner override by Anonymous (12/10/08 1:03 AM)
This worked for me - I have a HL-2040. It resets the page counter:

1. Open the front cover and leave open while completing the following steps.
2. Turn the printer off.
3. Hold the 'go' button while turning the printer on. All panel lights should be on.
4. Release the 'go' button.
5. Press the 'go' button 2 times.
6. Pause.
7. Press the 'go' button 5 times.
8. The toner light should be off.
9. The paper light should be on or flashing.
10. Close cover. The ready light should be the only light on.

When you look at all the many postings about this problem over several years, it seems ridiculous that the typical non-tech homeowner should have to put up with so many problems. It takes MAGIC to solve them, and is enough to be a TOTAL TURN-OFF for the average homeowner who is trying to use a computer system.

I have a MFC-9440CN with 2700 pages printed using the original cartridges, and just began to get a low toner notice for black, and then for the three color cartridges. So I tried the tape over the window/square hole tricks, but that did not work consistently. Then I tried to reset the counters as described by Brett in SoCal, and I no longer get the low toner message. Thanks!!!

When doing the reset for the "Toner life end" on the 7820N, remember to tape the toner "eyes". If this is not done, there is no way the reset will work. I tried the : Front door open/start/10/front door closed procedure and it worked so far.

Not sure who posted the tip below but Thank you, thank you, thank you - tape on the sensors didn't work but this saved my wife's business $300 (and me from losing my mind)!!!!!!! (Brother HL 4070 CDW)

For the toner life reset menu:
1 Open the front cover of the printer
2 press and hold the cancel button
3 press the reprint button WHILE still holding cancel
- here is the reset menu - go to the appropriate cartridge on
- the menu and reset it and you're done!
FYI... Pressing the "Go" button and the up arrow gives you the parts life reset menu (drum, laser, fuser, etc.)

Have a Brother 4100e and was able to resume printing after using the electrical tape trick in 3 places: one very small eye above where the drum cartridge sits on the right and two larger,glass eyes on either side of where the drum cartridge sits, left and right. Replaced the drum cartridge and back in business. I hope this saves someone else from toner drama!

Am I a half wit? My Brother HL-4050CDN said replace black toner this morning and it had stopped printing. I did this and for a while it spewed out some goobledigook (previously sent docs I guess, but just coming out as stars and squiggles). Having cleared this backlog from the Print queue and tried turning off and on again both the computer and the printer, I now have a totally unresponsive printer. Any print job I send, gets no reaction from the machine although its display says 'READY'. Meanwhile, the three other toner dots (Y M C) are flashing.

Is this a case for the tried and tested duct tape or what else would you suggest?

Thanks!

Have a Brother HL-2140 Monochrome Laser Printer in which I replaced the TN-360 toner cartridge with a new cartridge. After installing, the toner LED indicator still showed the cartridge to be low on toner. I called customer service and they tried unsuccessfully to turn off the LED indicator and ended up saying they would replace the cartridge if it were less than 90 days old (which it wasn't) otherwise I could continue to use it as there would be no damage to the system or reduction of life. Printed 123 pages when a pop-up on my computer screen said to clean the corona wire. Cleaned per their instructions and tried again to print and got the same pop-up. Repeated a half dozen times without success. Called customer service... they had me repeat the cleaning proceedure; shake the toner cartridge end to end and do other operations such as hold down a switch under the front cover while I turned power on to the printer; pressing the switch twice & pressing the switch 6 times, none of which fixed the problem. They then said the only solution would be to replace the toner cartridge with a new one, but again they would not replace it, since it was more than 90 days old.
Thought I would give a try to see what would happen if I blindfolded the toner level sensor port... IT WORKS!!! It has been printing like new with no "low toner" LED or pop-up to "clean corona wire."

Recently, 2 cartridges (cyan and magenta) on my HL-4040CN that had been indicating they were low, suddenly and simultaneously quit on me. (Oh come on! Does Brother really think consumers are so stupid to believe that 2 cartridges would become empty at exactly the same time?)

Anyway, the purpose of this post is to show that what worked for one cartridge wouldn't necessarily work for the other cartridges, even though they are from the same printer. (Go figure!) From my earlier contributions to this thread, readers will recall that all I did to revive my supposedly "empty" yellow cartridge was to cover one of its windows. Well, I figured that method would work for these other cartridges as well. But it didn't until I also reset them via the printer's control panel (as explained by aet2u and others earlier in this thread).

We have a Brother HL-4040CN which conveniently decides that all three of the colour toners are empty at the same time, BUT with our machine is impossible as it rarely prints colour. We also noticed the removed toner cartridges were the same weight as the new ones and could see toner through the little round windows so I contacted Brother who advised me to reset the toner counters as the machine counts the pages and assumes the carbon is depleted, that's ok if you remember to do it at the right time.

BUT thanks to this forum I taped the holes on both sides of the carrier on all four toner slots and was able to put an old "supposedly Empty" Toner back in which seems to have tricked the machine into thinking it's a new one. This hopefully will save us hundreds. Thanks guys above for all your tips.

On my HL 2070n (network version) with the original TN350 cartridge:

* I tried covering just the sensor window on the non-gear side of the cartridge
* I tried covering both windows (gear and non-gear side)
* I tried covering the sensor windows on the inside of printer
* I tried holding down the go button after opening the toner door, waiting until the three front lights were on, then putting the toner back in and closing the door to try to reset the toner counter

None of the above worked! It still has a solid amber toner light. I also did a factory reset, i.e. turn the printer on with the go button held down until all lights are on, release go and wait until the lights go out, then press go 6 times and wait for reset.

Again nothing worked!! I don't understand how you other guys with 2070's are getting this to work but it's not for me.

Hello. I came across your site, as I was looking for tips on how to make my printer ink last longer. I have a Brother HL-4040CND lazer printer, and its telling me that dreaded message, life end ink. And I KNOW there is ink left!
I contacted Brother about this and asked them to help me with this override thing, and he told me there is no trick that he is aware of.

Well, I heard there is a way to override this message but, I can't figure it out. I examined the cartridge and I can't find the "chip" or eye hole is situated to cover it up to fool the machine to print again. This is SOOOO frustrating!!!! HELP!!!!

If it's HL-4040CDN, you can download its manual from http://static.tigerdirect.com and see if there's anything there to help. (Just right click the link and from the context menu choose "Save Link As...")

Hi Abajan.
thanks! i'm sorry i got those numbers confused. its a HL-4040CDN!!! and I GOT IT TO WORK AGAIN!!!! I did a bit more reading on this site and seen that you can place tape over the holes to trick the printer in thinking the cartridge is full. well, I read that before, but, couldn't find any specific "hole" or sensor that I could cover up. so, I just took a pc of painters green tape and proceeded to cover up any thing that remotely looked like some type of sensor. my first attempt was to cover the clear little plastic 'washer" type circles, that are situated on either ends of the cartridge, right in the middle of the drums. and voila! IT WORKED!!! I continued my printing today and am at A TOTAL OF 1000 PAGES OF TEXT!!! Ya, you read that right. One thousand!! Ha! I knew there was more ink in that thing! Dam printer companies! trying to get us to buy more ink! and the waist! can you imagine the waist!! most ppl don't know this trick! I'll make sure to tell all my friends about this one!

The display on my HL-4040CN started flashing, indicating low toner, so I performed all 3 of the cures recommended..

1) Block the optical sensor hole on each cartridge
2) Remove the end-cap from each cartridge and reset the flag gear
3 Reset the software counter for each cartridge

The whole job was easy and took less than 15 minutes, and the display stopped flashing. Here's my question....I'm using the initial starter cartridges and will probably purchase larger cartridges when these eventually run out of toner. Like a previous poster asked...what would be the downside of simply removing the flag gear and spring (they come off easily) instead of resetting it to the start position? I know this gear also has a tang that changes the bias voltage as the toner is depleted, but wonder if removing it would make a noticeable difference. Thanks for all the great help. - Dave

"I have the same printer. Have tried the tape over the optical sensor without success."

Did you block all 4 of the holes that the sensor monitors (one on each cartridge)? Some block those holes/windows on the individual cartridges. I found it easier to block the 4 holes located on the outside of the cartridge pullout tray, that align with the plastic windows on each cartridge. Good luck.

Re: Brother MFC-9840CDW
Printer has 4 cartridges 3 color (magenta, cyan. Yellow) & black.
Printer is used mainly (90\%) noncolor printing so I was puzzled when magenta low toner message appeared 1st. Then yellow and cyan. appeared, but printer continued to print. Then when black went "low" and then "out" I replaced the black but...printer would not function. Called Brother tech. support and they informed me that unless I select "mono" rather then "auto" the printer still uses color drums. Thanks for telling me that now!
I bought new color cartridges and replaced each, one at a time, and the message for that toner would disappear. Then I would put back in the old cartridge and replace the next color new cartridge. After doing this the printer printed fine using the old cartridges. I again called tech. support and complained but they just said that the printer operates off some page count.
So how do I override this page count so that it uses all the toner? This is a new machine and my first toner replacement @ $80 per toner cartridge I need to run them dry!!

ladman - Here's the procedure that another owner of that model previously posted....

1) Open the door as if you were going to change the toners
2) Press the Clear/Back button
3) The Reset Menu appears!
4) I reset all of the TNR-S (four of them - one for each color)

I don't have that model, but on my HL 4040CN the Reset menu showed two settings for each cartridge (8 in all) and I reset all of them.


Good luck

on the TN-540 toner cartridge whitch on is the sensor hole?
by Anonymous on Aug 28, 2009 at 8:25pm Add comment
I'm not familiar with that model, but on mine there's a 1/4" round plastic window on each end of the cartridge. On mine, the one on the right side is most visible. Examine the yellow cartridge, because on this one the bright yellow toner is most visible through the window. The low toner detection system works by shining a light through the window on one end. If a sensor on the other side of the tray "sees" the light coming through the cartridge, because the toner no longer blocks it, it assumes the cartridge is empty and displays the low toner message. Blocking either hole blocks the light, so the sensor thinks the cartridge is full. As I mentioned previously, because the sensor is on the printer case and not the pullout cartridge tray, I found it easier to block the 4 holes on either side of the tray that align with the cartridge windows. Good luck. - RVdave

For the Brother TN360 you can buy a kit to refill your cartridge. I also bought the reset gear as my original cartridge didnt have one.

Its pretty easy to refill, just remove the cap (hidden behind a sticker) empty ALL the old toner and refill with new.

The reset gear is at the opposite end and you need to remove some screws to access it.

You can buy / get more info here (US)

Where is the sensor window to tape over on a non-oem toner cartridge for a 2170W? I have a plastic toner container slotted into a plastic sled, then the sled + container combo slide into the printer. Is the sensor hole on the right side of the sled? Is it a 1/4 inch circular hole in the black plastic of the sled that you are supposed to tape over? Or is it a place on the toner cartridge? Is it on the bottom of the sled, or on the side?

I can't find the sensor spot. I've got 4 pieces of Sharpied masking tape littering the sled, and no results.

Thanks.
by mastjab on Sep 4, 2009 at 8:42pm Add comment
mastjab - If that model has a low-toner detector there will be a hole/window on each end of the cartridge. Remove the cartridge and hold one end up to a bright light. Looking at the other end you may be able to see light through a hole/window on that end. When the toner gets low the light can go all the way through and be seen by a sensor that tells the printer's "brain" that the toner is low. The light source and sensor are mounted inside the printer cabinet, so there are also corresponding holes in the tray, so the light beam isn't obstructed. The purpose of the tape is to intentionally obstruct the light beam, so the "brain" thinks the cartridge is full. Some block the hole/window on the cartridge, while I blocked the corresponding hole in the tray, it doesn't make any difference as long as the light beam is blocked from reaching the sensor. Hope this helps.

I just put the piece of tape on the sensor and got another 500 pages or so, so far. On the brother HL4040CN (and probably the HL4070CDW too) the "window" to tape was on the gear side and was a clear plastic thing hidden behind another plastic guard with a hole that lined up with the clear plastic window.

The plastic window is on both sides of the toner cartridge, so I would presume that on different brother printers, the sensor is on different sides. 3,000 pages later I'm still on the stock toner cartridges.

It doesn't matter which side of the printer cabinet the light source and sensor is mounted. Blocking the cartridge "window" on either side of the cartridge will keep the light from reaching the sensor, thus defeating the low-toner warning.

YES YOU CAN RIG AN INKJET BROTHER PRINTER TO RUN WITHOUT REPLACING THE COLOR CARTRIDGES!!!

On my Brother MCF 5490 cn I was able to easily slide back the front piece of the printer cartridges and tape over the clear part that becomes exposed. Works like a charm!!! The only thing to worry about is when the remaining ink does dry up, it can damage your printer at a later date if you try to print in color.

Now I am very happy with my brother printer...

I tapped the sensor holes on both sides as well as on the printer. Nothing. I then followed JUPPO's instructions:

I want to override toner replacement on a Brother laser HL1400. Anyone know a semi-permanent technique such as the electrical-tape-over for my machine? I used a page reset code, but it's a pain to do it every time I want to print. I don't see an eye or a white switch that is mentioned on other Brothers. Here's the page count reset I'm using if anyone wants it:
1. Open the front cover and leave open while completing the following steps.
2. Turn the printer off.
3. Hold the 'go' button while turning the printer on. All panel lights should be on.
4. Release the 'go' button.
5. Press the 'go' button 2 times.
6. Pause.
7. Press the 'go' button 5 times.
8. The toner light should be off.
9. The paper light should be on or flashing.
10. Close cover. The ready light should be the only light on.

I'm not a scientist or anything but basically when a brother printer says the toner is spent it isn't joking or trying to rip you off. The residual toner in the cartridge isnt' capable of maintaining a proper charge. Continuing to use this "substandard" toner can cause problems down the road. That's the claim and it seems to make sense really. It was explained in detail in the instructions that came with my refill kit detailing why all residual toner should be removed before refilling. I hope this helps to prevent some people from ruining their printers or other expensive parts. Just get a refill kit and save lots of money.

With all due respect, that doesn't make much sense. Why would the second half of the cartridge toner be any more "substandard" than the first half, particularly since it all came from the same batch? Also, why would only half (1500 copies) of the toner in a small color cartridge be OK while twice that amount would be OK in a black or larger cartridge? Full cartridges do tend to supply more toner, and that's why the flag gear has a tang that adjusts the voltage to maintain copy quality consistency as the toner is depleted. - RVdave
What type of refill do you recommend? Does the quality suffer? Do you refill both black and the color cartridges?

Anonymous, considering the sheer quantity of quality printing many of the contributors to this thread have done since getting the “Toner Life End” message, we are hard pressed to believe that only “residual” amounts of toner remains in those cartridges.

This forum is saving the planet. Can you imagine how much toner has gone into landfills as a result of bogus "low toner" messages??

Personally I love Brother products because of their value for money and the features you get. If only we could convince Brother to let us know these tips and tricks from day one we could get the best value from every gram of toner and they would have even more customers.

I can't stand the brands that write the bogus toner level to an electronic chip on the cartridge - that way you can't do the sort of reset thingy posted on tis forum.

Maybe it's time we took some of these manufacturers to court for environmental destruction.

Hi. Got a Brother CDW 4070 colour laser printer. I print about 2000 sheets a month, nearly all in black text. I put a little colour on odd lines, perhaps ten words a page. It seems the machine sees any colour as a full colour page. It says the cartridge is empty when it is full - a licence for Brother to print money at about £100 for a colour cartridge.

Can I reset the toner cartridges to stop them telling the printer that a few words means a page?

Thanks for any tips.

Nigel - Unfortunately, ANY copy made counts as a copy on each cartridge, even though the copy may be all black. Some models allow you to put the printer in a "monochrome" mode, so only the black cartridge is used and the counters for the color cartridges are disabled. The downside of this, however, is that you'd have to switch back to full color mode every time you need some color. Good luck.

I have a HL 4030CN and the taping trick has worked for my magenta and cyan but fails to work on yellow. Anyone else encounter this problem and have you been able to develop a fix?

Yes, I had a similar problem (search the thread) and found that, in addition to placing the tape over the window, the cartridge also needed resetting via the printer’s control panel. See if that helps.

BTW, my printer model is the HL-4040CN. - abajan

Maybe the reset procedure for the HL 4040CN will work...

1) Open the door as if you were going to change the toners
2) Press the Clear/Back button
3) The Reset Menu appears
4) Reset all of the TNR-S settings(four of them - one for each color). If two settings are shown for each cartridge, reset all 8.

Good luck.

Dave, thanks for the suggestion but its still a no go. This printer doesn't have a "Clear" button but I assumed "Cancel" was its replacement. Control panel displayed "no data". I also have reset to "Factory Settings"

I've purchased a new yellow toner (the offender) and I continue to receive a "replace cartridge..." message. Cyan and magenta are taped over.

Sort of odd but I get a cyan and magenta toner low message and no mention of yellow until after sending a job.

The offending cartridge set works in another printer. But fails for yellow when returned to the original printer.

Any more suggestions?

Yes, the Cancel button should work. Are you pushing that button with the front of the printer OPEN, so that you can see the handle of the cartridge tray, etc? - Dave - RVdave
Printer still isn't working but I did learn, with your help, that I could reset the long life consumables by pressing Go and +.

I'll try the taped cartridges in a different printer tomorrow and report back.

I just had the yellow toner 'end of life' on my HL 4040CDN Brother. I tried the electrical tape thing and nothing worked so I went out and bought a new toner cartridge for $89CAD.

I compared the print copy between the old and new toner under a magnifying glass and could find no difference. After printing about 10 copies with the new cartridge, I put the old cartridge back in and the 'end of life' did not come. The copies were perfect (with the original cartridge). Over 200 more copies and still can't tell the difference.

I just resealed the new cartridge and will wait until the original one is actually empty.

I wonder if I can use the new yellow cartridge to 'reset' the others? Does the printer know which toner is in which slot?

A repeat of my asking for help from 3 weeks ago, perhaps someone who did not see it before has a suggestion or solution?

Have a Brother HL-2140, refilled it's initial TN-330 cart. after emptying the residual toner and installed the extra gears.
Now the print is not black but dark grey (density is too low), tried all the adjustments I could find but nothing helps except lowering the DPI to 300 which makes the print a bit darker, but still not black.
Any suggestions on what to do?
I did the multi step reset outlined in this forum and covered the tonner window with black tape, the only change is that on the print test page the Toner level indicator graph dropped from 90\% to 50\%.
Perhaps related: Am not sure about how to set the position of the flag gear, at what "hour" of an imaginary clock should it's white flag point after installation?
Thanks for any help, Eldad

For the TN-110 cartridge, has anybody found a place that sells the the reset gear that needs to be used to make it a NT-115. The NT-110 has a grey gear with 1 rib (finger) but the NT-115 has 2 ribs (fingers) to give wire a higher voltage if completely filled. My full refill in the cartridge that came with the printer TN-110 is working fine, but would like to get the right gear for it. I found a place in Australia on eBay, but only sells the gear with the refills as an extra.
Looking forward to hear about a place where I can get them,

I successfully reset my genuine Brother TN-110 Cyan, Magenta and Yellow cartridges. I have a 4040CDN and no amount of sensor covering - via electrical tape or sharpie black marker was working for me but thanks to reading through all of the threads on this site, as well as other googling, I was able to re-set them with the internal gear re-shift. In my opinion, and I am a former Xerox filed technician, it seems impossible to re-set them without performing this step. The photo that says "Set the reset gear and spring as shown." - the second to the last step is all you need to know. http://www.proprint.co.uk/brother_hl4040.htm Hope this helps someone. I'm curious to see how many extra prints I will get out of them...if anyone's interested, I'll post again when I actually "have to" replace them.

I have a Brother HL4040CN less than one year old. I've only printed about 40-50 pages and am getting "End Toner Life" message for all colors! I have never got a Low Toner warning. It will not even attempt to print a page if the page has color on it. I’ve pulled the cartages and shook them, cleaned the wires, etc. and none of this does any good. It seems after a period of time there is some built-in feature that gives the message and locks it up. Before I take it to the dump, does anyone have any suggestions?

I had to stop a print and got a paper jam. Cleared the jam, and then got end of toner message although only put in 6 weeks ago. Toner cartridge TN2000. The last one lasted a year.

I have no solutions, only observations that someone may benefit from.

I spoke to Brother techie today and he said that on a cartridge being inserted it tripped a switch. Couldn't be reset, he said!!

Returning the cartridge, but hereafter I will keep the 'spent' to refill newer ones.

Also noted, white lever on the 'old' one all the way back, whereas on the new one, all the way to the front. Gently tried to move forward, but no go. Didn't push hard as nearly full and hope to get a new one.

Also noted that the silver disc on the new one (left hand side front) total, whereas on the old one, 3/4 moon.

When I get an old one I will try and flip the switch forward, and maybe cover the hole at the front (left hand side, sharp end) away from you, as if you were going to load it), or try the options/00 trick.

If there is a switch, then something on the toner cartridge is tripping it. There has to be a release pin somewhere to allow the easy winding of the gears.

As I said, observations, my last old (the old one before replacement by the now 'old' one) cartridge was doing a good printing job until the machine refused to allow printing.

On the older machines, there was a reset procedure but I guess they wanted more revenue so withheld this, or changed the mechanism. If they are reusing, then there must be a reset/hole/button mechanism which is easy to allow the gears to move easily, if you know what to do.

Thanks Caryboe.

Using the link, it took me just 15 mins to reset all three colours on an HL - 4040CN. The RHS of the end cover feels like it won't come off and I was initially worried about breaking it but, with a little gentle persuasion it was OK.

I will now make regular visits to this forum in the hope that I will be able to contribute.

Thanks again.

I have an MFC-7840W and have used both the TN-330 and TN-360 cartridges - both of which I thought had very low page yields. I was delighted to run into this thread and thank everyone for contributing.

I was having trouble figuring out which one of the many holes was the sensor to cover, but it looks like I have figured it out:

For this model, the TN-330 and TN-360 cartridges go into a larger plastic black tray before going into the printer. There is a hole (as mentioned by another user, a little smaller than size of a dime) on the RIGHT side of the tray/cartridge (facing the front of the printer) that I covered up, and I have just printed a page, it printed out perfectly, and the "LOW TONER" message has disappeared...

I used a small 1/2 x 1/2 inch piece of scotch tape which I even colored with a BLUE (for the lack of BLACK marker here) and it worked! Lol.... thank you to all who have contributed.

Hi Guys

Thanks so much for your advice on placing tape over the eye, it saved me a lot of trouble with this printer. I was going to throw it through a window when it kept saying it was out of toner, but the last page printed fine (and it was a new cartridge).

Same here about what an awesome override, the tape I mean, on the non-gear side of the MFC8640 toner cartridge sensor. A little bubble eye, the toner level sensor, is on the inside right wall of the printer cavity where the toner/drum cartidge rests. Look with a flashlight, you will see it a few inches from the front. Saved a few hundred dollars on a replacement fax. I hate throwing away an otherwise perfectly good appliance.

Following on from my message of 11/23, the cartridge returned to Brother has been returned to me, reset. So the nonsense about not being able to reset is male bovine excrement, so my reasoning is correct, there is a reset hole somewhere to allow the lever to be moved easily.

The 4070 can autoduplex, but it needs to be set on screen as follows:

File
Print
Select HL4070CDW if you have more than one printer connected to the computer
Properties
Open Duplex/Booklet (at right of screen)
Tick Duplex
OK.
Remember to check for the next batch of duplex printing; the printer may reset automatically to non-duplex.

"Remember to check for the next batch of duplex printing; the printer may reset automatically to non-duplex."

Nigel, I don't have an HL-4070CDW but I'm guessing that if you want your printer to do duplex printing by default, just click Start > Printers and Faxes > right-click "Brother HL-4070CDW" and choose either "Printing Preferences" or "Properties" > Open Duplex/Booklet > check Duplex and hit OK.

That way duplex printing would be the default setting for every program on the computer. (To my knowledge, that's the way most printers work in a Windows environment.)

Yes, indeed it works... jst cover the round hole on the right side (non gear side). I did not notice any image quality reduction prior to the printer deciding it was out of toner. I suspect this auto shutoff "feature" was a boardroom answer to "how can we increase profit?". Well fortunately there are regular folks who can hold a web discussion on "how can we preserve cash?". With electrical tape, same way we fix our glasses! Power to the people!

To avoid damaging the printer, closely monitor your printouts and when you notice the colors are not right, stop printing whatever job you have spooled and print a test page.

Here’s how: Go to http://mintaka.sdsu.edu/GF/explain/optics/color/intro.html and scroll about halfway down the page till you get the red, green, blue, cyan, magenta and yellow squares onscreen. Now hit the “Print Screen” key, open “Paint” or any graphics application of your choice, paste the image into a new document and save it. Print that document and you will be able to tell which of the color cartridges is empty. Knowing if the black one is empty is somewhat trickier because the printer can mix the other colors to produce a brownish black. To get around this issue, periodically print documents using the "black only" setting. If the document does not print or looks very faint, replace the cartridge.

I hope this doesn’t sound too confusing!

What is weird is that I have 3 of the HL-2040 printers, and all have the flag @ 3 PM, even the Brother OEM, and all print well.

No idea why you get gray instead of black - what is your system? OS? Have you changed any of the printer settings? I think that the printer set-up in Windows allows you to change some, no idea if a Mac allows you (have to check), no clue what Linux allows.

Well, seems like the flag is basically good for nothing, except perhaps to adjust the toner supply or density according to the amount of toner left in the cart. as explained someplace that I saw, but seems it is not doing that either.

WinXP-PRO-SP3 here. I played with all the printer adjustments on the printer preferences dialog, but cannot get real black like when it was before I refilled it.

The company (Laser Tek Services - very nice and good prices!) even sent me a replacement toner, but it was the same. They said they had no such problems before.

Ok, folks, this is a long response but you will find it helpful.

We are an experienced refiller, remanufacturer of toner and components and printer supplies for all factory OEM systems.

In the case of the Brother 4040 / 4070 printers there is an issue with ALL of the refill toner on the aftermarket, including ours. Fact is, there are only a FEW companies in the world, if that producing the color toner for this printer. One of the reasons is that it works differently than most other toner. The toner for the Brother 4040/4070 is a positive charge toner (as opposed to negative. Most laser printer use negative. Without getting too crazy, it all has to do with what charge is used to ultimately attract the toner to the drum then onto the paper.

OK, so having this background, it is difficult at best to duplicate the Brother 4040 / 4070 toner exactly and the aftermarket toners out there are close but not exact. With that, when you use a refill kit you must do 2 things.

First, use up or get out as much of the original toner as possible. We use a toner vac called an Atrix but a good shop vac with a fine filter will do. Remove the plug, use an narrow tip tool on the vac be patient, rock the cartridge and get it as clean as possible inside. The problem is, because the aftermarket toners are just slightly different, the DO NOT MIX WELL with the original brother toner. Even if only 10\% of the original Brother toner is remaining and you fill it up with aftermarket toner, you WILL HAVE A PROBLEM in the form of leaks, streaks and a general MESS. We have 4 of these printers and have tried this hands on.

Second, you must reset the flag gear to the full point. If you don't you will just end up with light ghosting in the background. The reason is, the position of the flag gear directly relates to how much voltage is being sent thru the cartridge. The easiest explanation is if the flag gear is at the near empty position and you do not reset it when you refill, the wrong voltage signal is sent thru the cartridge resulting in problems. If you do not know how to reset the flag gear, email me at [email protected] and I can send you an instruction sheet.

Hi all,

I have a Brother HL-4040CDN. I print with mainly black toner, except for a tiny bit of color in the letterhead. When my color counter hit 2600, I got the annoying red light and message to replace M, C, & Y cartridges. Since I mainly use black toner, it is nowhere near time to replace these cartridges. I followed the directions in an above posting that tells how to find the hidden menus and I am now successfully printing again. However, I did see those infrared sensors inside the printer at each cartridges station, so I put black electrical tape over the cartridge holding unit where the light would shine through because I do think that when the toner really does start to get lower, those sensors will kick in a secondary control and give me another headache. Hope this helps.

I have an HL-4040CDN. I replaced black cartridge after too few copies, but didn't throw the old one away, so I will re-use. After 1594 color copies and 1734 mono, printer came up and said that all color cartridges needed replacing. I saw these threads and opened front cover: placed black tape on both side of the slide-out track where the machine looks through to the cartridge. (seemed an easier place to put the tape than on individual cart.)
I reset all the cartridges by holding down reprint and cancel simultaneously. The list of items is confusing to me, but I re-set them all. There are 2 settings for each color and black, it seems Hope that's not a big problem. Closed the front cover and the printer works again. I will try to remember to re-post again when the cartridges actually run out or quality degrades.

We are getting the 'toner life end' error message. Replacing with identical non-OEM TN-360 cartridge does not remove the message. Covering the low toner sensor holes makes no difference. How do you do a software reset of the error for the 7840?

Hi...Did you ever figure out how to override the toner life end error message?

Please advise

Thank you.... - Anonymous
Regarding the HL-4040CN and similar models, one way to get (significantly?) more prints per cartridge that probably most of us overlook is to simply turn on the Toner Save mode. Think about it: Do you REALLY need to use the standard setting for most of your print jobs?

Here’s how to turn the Toner Save Mode on globally in Windows XP: Start -> Printers and Faxes -> Right-click "Brother HL-4040CN series" and then click "Printing Preferences..." in the context menu -> Advanced tab -> Immediately below the Advanced label are five buttons with the first one (Print Quality) depressed by default. Click the last one (Device Options) -> Under "Printer Function", select "Toner Save Mode" and on the right select "On" -> Click "Okay" -> Close the Printers and Faxes window and you’re done.

Now, Toner Save Mode will be on by default for all programs on your computer. (Please note that Microsoft Office documents previously printed on your computer may have saved their former print settings and may override the global Toner Save setting.)

This is a long post, but read it all. I am a printer tech.

To reset the toners you need to open the front cover then hold "cancel" & "reset" together and the toner reset selections will pop up. Each color has 2 choices, the "s" for TN110 cartridges and the "h" for TN115 cartridges. If unsure which cartridge you have you can just reset the "s" and "h" for the troubled color. If you have used the tape trick, at some point a cartridge may start to print light before the printer shuts it down so be aware of that and watch your print quality.

To reset the components like the laser unit, belt, drums etc you need to open the printer cover again. Press "go" and the +/up button and the reset menu for each component will appear. Now press the +/up button to scroll to the component you want to reset. Once you are at the correct component, press the "OK" button and the reset is done. Close the cover and let the printer recycle.

If you choose to refill your own cartridges, you can save big money. I am a tech and our site at yourprinterink.com has just about anything you need. You may start to get backgrounding in which case you will need to reset the "flag gear" in each cartridge. This is easy. If you need to know how, email me and I can send you a pdf 1 page instruction sheet.

In the case of the Brother 4040 / 4070 printers there is an issue with ALL of the refill toner on the aftermarket. Fact is, there are only a FEW companies in the world, if that producing the color toner for this printer and there is a great deal of JUNK toner on the market especially on ebay. One of the reasons is that it works differently than most other toner. The toner for the Brother 4040/4070 is a positive charge toner (as opposed to negative). Most laser printer use negative. Without getting too crazy, it all has to do with what charge is used to ultimately attract the toner to the drum then onto the paper.

OK, so having this background, it is difficult at best to duplicate the Brother 4040 / 4070 toner exactly and the aftermarket toners out there are close but not exact. With that, when you use a refill kit you must do 2 things.

First, use up or get out as much of the original toner as possible. We use a toner vac called an Atrix but a good shop vac with a fine filter will do. Remove the plug, use an narrow tip tool on the vac be patient, rock the cartridge and get it as clean as possible inside. The problem is, because the aftermarket toners are just slightly different, the DO NOT MIX WELL with the original brother toner. Even if only 10\% of the original Brother toner is remaining and you fill it up with aftermarket toner, you WILL HAVE A PROBLEM in the form of leaks, streaks and a general MESS. We have 4 of these printers and have tried this hands on.

Second, you must reset the flag gear to the full point. If you don't you will just end up with light ghosting in the background. The reason is, the position of the flag gear directly relates to how much voltage is being sent thru the cartridge. The easiest explanation is if the flag gear is at the near empty position and you do not reset it when you refill, the wrong voltage signal is sent thru the cartridge resulting in problems. If you do not know how to reset the flag gear, email me at [email protected] and I can send you an instruction sheet.

Thanks very much for your learned input, Rich. I’m certain your post will be invaluable to many experiencing problems with their printers.

I’ve never used refills for my HL-4040CN but your information regarding which charge the toner should have is definitely worth bearing in mind.

Cheers :-)

Cannot fix the problem here with my HL-2140 printing light (grey instead of black). I did not try a new cartridge, just refilled again the one I have. It started printing in grey after I refilled it and installed the flag gears on it, it is the initial cartridge that came with the printer.

Tried everything I could think of, tried all the choices in 'Preferences', and a few suggestions from this great site, but still printing grey.
Anybody here that actually experienced this problem and solved it?
Thanks for any help,

I have a DCP-7020. I've taped over the sensors and this has worked in the past, but now it's giving me the 'toner life at an end' message. Is there a way to re-set the printer, using the buttons, and override this message? I would rather try this before taking apart the toner cartridge. This forum has instructions for re-setting other models, but they don't work for the DCP-7020. Does anybody know the override sequence for this particular printer? Thanks.

Which Brother Printer Model number do you have? - Anonymous
Are you sure that even though the toner cartridge is red (magenta)that the toner INSIDE is the correct color. You either have the magenta and yellow switched or you have a magenta cartridge with yellow toner in it.
by USAMKTG on Jan 30, 2010 at 9:07am Add comment
Chenrp, it sounds like your magenta cartridge is either empty or its ink has hardened. Another possibility is that that cartridge’s nozzle has become clogged (check your user manual to see how to clear it).

To achieve a red output, the printer must mix ink from the magenta and yellow cartridges. The red square coming out yellow suggests to me that magenta is not being printed.

HL 2030

toner light won't go out - so far I have followed these solutions:

Try this. Take the toner cartridge out of the drum it sits in. Look on the left side. You'll see a half circled groove with a tab inside it. If the tab is turned to the right(3 o'clock position) then you'll have to switch it to the left(10 o'clock position). This happens when you try to change the cartridge while the printer is ON. This is the most common solution to this problem.

on the 2030 the old Brother cartridge does not have this "tab" but the replacement (non-Brother) cartridge does but it is impossible to move it to the 10 o'clock position.

have tried covering both "eyes" with electrical tape - no luck

did a factory reset (the 6 times hit on the go button) - no luck

switched off - pulled out plug and cartridge and waited 30 seconds a dozen times - no luck

Pulled out cartridge when printer was on - held go button until they all lit up, replaced cartridge and closed front - no luck

Pull out any toner cartridge and hold it by the handle. Look on the right side of the cartridge. You will see a label that is actually covering the FILL plug. Now look just below the fill plug and to the left and yoy will see a CLEAR PLASTIC window. It is round and that is what needs to be covered.

Black tape over sensor works on my HL-3070CW. Wish I'd found this earlier before buying new cartridge and having marathon argument with Brother 'Customer Service' about why it ran out after only 282 pages with average coverage of 1.46\% read all about it at http://bit.ly/apWF7F

Having trouble with my brother HL-3070cw here. It was not responding to tape over the toner carts, or tape over the sensors themselves. The only thing so far that's helped is to put in a new toner cartridge, then close printer, etc. Let it print something real quick then swap the old (partially full) cartridges back in. I have covered the old carts with tape on both sides, but I don't know if the printer will catch on again, or not.

Has anyone gotten anything to work with the HL3070cw? I'd like to know if there is a printer toner reset menu that I can't find?? Maybe the page count is resetting for each toner cart. when putting in a new one, which is why I can then swap the old ones back in??

If I could just reset the toner cartridge count it might work without the added step of having to put a new cartridge in for a minute to trick it.

So, where is toner reset count menu for HL3070cw?
And has anyone else had luck with resetting toner for HL3070cw, if so, what worked?

I'm frustrated - my magenta and cyan cartridges have never been used, and stupid printer wanted me to throw them away and buy new ones!!!#$\%^

My brother HL-3040CN is not responding to the black electrical tape trick. Is there anything else I could try in order to override the low toner messages? I have searched for a individual cartridge reset menu with no luck as well.

Excellent.

I bought a hl2140 recently with a starter pack and the toner low has been going the last few days. Today it wouldn't let me print at all. I went to office max and they wanted stupid money even though the print quality is fine for what i need.

so i did a little google and you guys came up - you're stars! I pulled the cartridge out and found the sensors on the cartridge on each side and put some brown parcel tape over them.

put the cartridge back in and fine, printing happily and still good quality.

1 - Open cover
2 - Press and hold Cancel then press Go while still holding then release both
3 - Select each toner in turn eg- K Toner STD and press OK then OK to accept. Do this for each cartridge.
4 - Press Cancel and close cover
5 - Printer will restart then show Ready
6 - Access via web interface and all your toners will show full or nearly full again.

Hi-- I own an HL-3070cw as well. I tried your override key sequence and it didn't work. Please let me know if the sequence is correct. I really wish I knew about this site yesterday, I just ordered a new set of cartridges and know that the ones I have are still good. I bought the printer only 2 months ago and rarely use it.

Thanks for your help. - newbrother
So finally today - nearly one year after my original post - I had to switch out the black and yellow cartridges. Used the override procedure only once and the so called empty cartridges have lasted another year. When they first showed empty the total page count was 213 - today it is 1943. 1700 pages left when it originally said empty!!! Bought compatible toners from http://www.leadingedgeink.com - will post results later - daddiogee
It also works on the Brother MFC-9440CN

Glad you had success!

Accidentally turned-off the "notify me if someone responds" feature on that thread and could not figure out how to get it back on. (sorry)

Was on here today doing the same thing for my girly's newer MFC 7340. Had almost the exact same experience. The other posters got us pointed in the right direction... first couple solutions did not work... (tape over sensors, chaotic mashing of random buttons, etc.) but we kept reading and trying new suggestions and finally... the grail was grasped!

Hi,

To sum up, only thing I could find to reset toners so far is to:
(note that taping over the clear sensor window didn't work)
>>> swap in new toners, print something (1 page just to be sure it worked) then SWAP OLD TONER CARTS back in. This seemed to let me keep printing just fine, printer never caught on (1000+ more prints since then). I just put the new toner cartridges back in the boxes and they are on the shelf for when I really do need them.

This may have been all that worked since up to now I couldn't find the toner reset menu in the printer menus itself. I think it's possible taping the cartridges COMBINED with using the toner reset menu will work without swapping in new cartridges at all. I haven't tried this yet, but next time it stops printing, I will report back on the issue.

Tonight I found the TONER RESET MENU after much trial and error and button pushing:

Toner Reset Menu for Brother HL3070:
1. Open Cover where you access toner cartridges
2. Press CANCEL & SECURE PRINT buttons at one time and you'll see the toner menus on screen
3. Press + or - to navigate through to the toners you need to reset. Note that each toner has 2 entries here, and I'm not sure why. Would love to hear what each one does, if anyone knows.
4. I'm guessing that the OK button will be the actual reset of the toners, if not then the go button would be I guess, but I couldn't confirm this, since my toners didn't currently need reset.

I also found the reset menu for the durable parts counters:
1. Open cover where you access toners
2. Press GO and + button at once, you'll see menu come up displaying reset counters for drum, fuser, etc.

Hope this helps someone else. I am so frustrated that we are all being forced to replace toner cartridges that are, in many cases, still mostly full! It's wrong, and forums like this one are important.

God Bless You.

I ordered a complete kit last night out of frustration for my 2 month old brother HL-3070cw.

It bothered me so much I started searching online and saw your post. Anyway, as of two minutes ago, my printer works fine thanks to you.

Nevertheless, when I get these new cartridges, I guess I'll just park them for when I need them.

Thank you again!

p.s. do you have a problem with your printer sometime saying that the upper cover is open? mine does on occasion and I have to give the top cover an extra push down near the front left of the machine. - newbrother

Hi Tammy

You are a Goddess. I tried this on my HL3040CN and it worked like a charm. And yes, the OK button is the one to press.

When you press OK, the printer responds with "OK?" Press OK again and the printer responds with "Accepted". i did this for all four cartridges, and now the printer says they are all full. Thus saving me about $360.

Thanks Tammy!!! - Notace

I prob won't buy another brother printer, they are as shoddy as the typewriters (yes, I had one).

Duct tape works, or seems to as well as electric tape. It's all I had in my classroom, it's a new toner drum. Tech support said the printer needs replacement and is it under warantee still? 1year, I've had it 15 months under a not heavy duty workload.

My old Xerox P-8E was approaching 100,000 pages when it died, we had 25 users and it lasted 4 years.... I miss "old and reliable" over the new and improved *sigh*

Sorry


I have a Brother MFC 9840CDW. I first got the Toner Low and then the Toner Life End message. After reading the various responses on this blog, I did the following to re-set the printer:

1. Turn on the printer

2. Push the button on the front of the printer to open the cartridge door. Don't remove the cartridges.

3. Push the Clear/Back button to bring up a reset menu. There are 8 different toner functions (for simplicity, two B's, two C's, two M's, and two Y's).

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.

Thanks for the info. I have an HL-4040CDN and have been using the "reset the gear" method on TN-110 cartridges, and it has worked fine so far.

Today I was resetting it and I wondered what would happen if I just left the gray gear and the spring out entirely. As an experiment I left it out and the print quality seems fine to me.

Will this keep me from getting the out of toner message until the cartridge is actually depleted, or will it likely cause me some problem down the road? Has anybody tried this?

Thanks again!

Here’s what I know about the 7340’s:
The tape on the eye solution does not work.
Messing with the “clock gears” sounds messy… and, “I don’t look good in black”.

Which leaves us the “random mashing of keys” approach:
Since mine is fixed, I can’t duplicate, then fix, the problem to remember just what I did.
Though I can tell you that my fix came from just reading and trying the solutions provided by our fellow posters here.

I think this was it:

1. Open the toner cartridge cover door
2. Press "Clear/Back" button
3. Question is “Replace Drum?” 1= yes; 2=no
4. Hit #1 and let me know if this works.

I have a Brother MFC-9840CDW that gets an Cooling Down (Error 25) message about every 5 pages. The machine stops, cools down, and then runs off another 5/6 pages, and then repeats this.

The Service Manual states that either the unit is overheating or the temperature at both ends of fuser roller is unequal.

The exhaust fans are all running correctly. The temperature at the fuser exhaust fan is 120F. Is this too high? I would not think so, but I don't have a specification. Anyone know for sure?

I called Brother's technical "support" and was told that my paper was out-of-specfication. We use Hammermill Copy Plus, 20lb. The recommeneded paper is Xerox 20lb or Hammermill 24lb. So you could argue that our Hammermill 20lb is "out of spec," but I don't really by this argument.

However, I did change the print setup from "Plain Paper" to
"Thin Paper" and we ARE getting a lot fewer Cooling Down errors.

Questions:

1) What do y'all think about this?
2) Is it possible that the fuser is "dirty" and needs to be cleaned? If so, any suggestions on the correct procedure?
3) Anyone else having this issue? I have not seen much on the web about this.

TallBob - It may be worthwhile trialling the heavier 24lb paper that Brother have said is within spec.

Sounds like it won't take too long to see if it changes anything.

If the machine is genuinely overheating because the paper is too light it may also be because your room temperature is too hot also.

(Used to see this a lot on the Oki 7xxx range and had to change factory settings for "standard" fuser temp to get it to run slightly cooler - although I have no idea if this is possible on the Brother).

Light paper doesn't "suck" as much heat out of the fuser so the fuser can tend to heat up progressively, and this effect is magnified if the paper temp is up, and room temperature is up.

Maybe also try keeping your paper in a cool place before you put it in the printer. (In the basement if it is dry). - greengeek

Thanks! Fixed the problem for a HL-2170W. The printer was brand new and I got this error on the 3rd day of ownership. Maybe I had printed 30 pages when it started giving me the error. Black tape cured it. Thanks again.

I stumbled across this thread while seaching for something else and I am amazed at the number of posts.

Because consumables represent such a HUGE portion of the revenue stream, you certainly wouldn't expect manufacturers to have to resort to tactics such as these.

Interestingly, this is not new, nor is it isolated to the printer industry. Does anyone here recognize the name Gillette?

That company made billions by literally giving away razors and then simply sitting quietly while the money rolled in from the sale of replacement blades.

Would anyone care to guess what class of products represents the largest revenue stream for that old stand-by company, HP? Might it be computers? Maybe printers? Possibly scientific / medical equipment?

Nope, none of these. Printer consumables is the correct answer.

I am pleased to know that this thread has survived, and that so many different people have been able to save a few bucks at the expense of corporate greed.

We can fight back, but just think about how many people blindly buy replacement consumables when the equipment tells them to do it.

Sheep.

Baaaaaaaaaaaaa!

A Retailer, I agree with everything you said except for the "so many different people have been able to save a FEW bucks" part because by my rough estimation it's probably more like hundreds or even thousands of dollars for each person that has been following these tips while doing lots of printing over the last few years.

Sorry for appearing cavalier.

A meant "a few", in the figurative sense.

A few can mean many things to different people.

Based on what consumables list for, it wouldn't be too difficult to save hundreds or thousands, especially if you need to buy them at full MSRP.

Even at a discount, these items cost far more than they should, if you buy the "brand" name item.

Once again, corporate greed.

I have a MFC-7840w, using a TN-2150. I also kept getting the "Life End" message on my computer and printer. I tried the *00 thing...didn't work, I even tried the sharpie to darken the windows on the toner cartridge, but that didn't make the message go away. I then cut two pieces of the sticky part of a post-it note and covered both sensors in the PRINTER, and now it seems to work. I guess the sharpie to darken the windows didn't cover it enough.

Hope this helps

How do I reset the drum on my MCF7840 so I don't have to buy a new one?
by unknown on Apr 3, 2010 at 10:55am Add comment
i did the reset toner menue 3 times in the past year and my mfc-9840cdw always printed like a charm.


now it insists on replacing the black toner!

even reseting the gear didn't help!

can something done be wrong when reseting the gear?
I reset it and after printing about 4 pages (perfect letters no fading) the replace-toner-nomoreprinting message reappears and the gear is in empty-toner position again... :-(

As far as I know there is no intelligence in the toner cartridge, so the printer should not be able to remember a used toner, or am I wrong?

any help is welcome

Dear Anonymous. Great note... and you are, of course, welcome! Now if I can just find one of these sites for the brakes on my Lexus!

If you find such enlightenment in the manual, do indeed let us all know... but don't hold your breath! As evidenced, you are not the only one to have been driven into the night in such fits of outrage... many have visited here and none have had news of any such documentation to report.

Your painful reminder that these Cossacks have the nerve to try to get you to replace all three separate cartridges simultaneously is even that much more galling! [In fact, don't such manufacturers regularly extol the virtue of such delineation as a significant cost saving feature?!?!]

OK, you've wound me up and I must calm down… *breathes… stares at candle flame*

I'll leave you with this... it has now almost been two years since my first posting here and its antecedent bogus notification from my otherwise beloved machine. I run two business from a home office environment and print regularly. The next time I replace ANY of my [4] cartridges… will be the FIRST!!! *is wound-up again*

Good luck! ...and keep fighting!

BROTHER MFC-7840W TONER LIFE END

Sorry guys, following all the tips here and it's not working on my Brother MFC7840W!! Tried taping both sides of the sensor holes on the cartridge itself, on the cartridge holder, and also inside the printer (using electrical tape).

Also tried sticking a punched-out cardboard circle into the sensor holes in the printer itself (both sides).

Tried doing this with printer on, with printer off, etc.

Also with cover open, pushing clear back and selecting replace drum (1) -- that didn't work either!!

Is this the latest cheat-proof model? I've read other posts on here saying they've fixed a MFC-7840W. What am I doing wrong?

Thanks

As a fledgling "work arounder", I discovered that by covering up the sensors, I failed to stop the "beep beep beep" and exclamation point demanding I replace the toner cartridge. WHat I DID discover was that even though it beeped and made its demands, that I could continue to print! (Which before doing the electrical tape/sharpie trick, I could not do)

Having said all that, the best solution was the one that I adapted from "BrettSoCal"'s post from June of 2008. I think this may work on newer machines (my 9320 is a newer model too). Basically, with the power ON, you open up the door to access the toner cartridges, and then look at the Menu which will tell you the door is open. With the door open, hit the Clear button. That takes you right to the Toner Reset Menu. Using the up/down<>"Search" arrow buttons, scroll to the RESET option and then for EACH version that displays (for Brett's it was B= Black, for mine its K= Black, then C for Cyan, M for Magenta and Y for Yellow, followed by option for either STD or STR on mine, but on Brett's its H or S. That means you reset a total of 8 "cartridges", NOT REPLACE DRUM, just hit the #1 option for each. Then hit Clear /Back to exit the menu, and close the door. It will whirr and spit and whirr some more (sounds like an old PP and M song) and then will congratulate itself on "resetting" and you can print to your hearts content. Brett tells me he hasn't replaced toner since!!

You may have gone the wrong direction if you picked up the "REPLACE DRUM" option, not sure, but I was really happy when this worked on my new MFC 9320. I put my electrical tape away and returned my black sharpie to my graffitti drawer. I know now what it feels like to be free! But I am seriously going to raise some serious hell with Brother. This is a deliberate effort to bilk their customers.

I print about 5000 to 6000 sheets of paper per year. Last year I owned an HP. I spent about $500 in cartridges, mostly Black and Yellow. I may have replaced one or two blue or magenta.

I have owned this Laser machine for about 60 days, in that time, I spent $210 in black toner cartridges and were it not for Brett (my new hero as I explained), I would have also had to purchase ALL THREE color toners, starting with Magenta. That would have cost me another $200+. At this rate, I would have burned through the cost of the printer itself EVERY 60 DAYS.

I was livid and made moreso when I talked to not only the tech at Brother, but his supervisor, both of whom were fatuous, condescending jerks, who when I confronted them that the Laser Black toner cartridge claims to be able to print 2200 pages, intimated that I must be outside the ASI standards with what I print. (I suppose to them, that must mean that I spend my waking hours converting white sheets of paper to black construction paper)

Anyway, I digress. Try what Brett recommended and that I refit to my new unit. The principle is the same.

Then lets all find out for me who the appropriate VP or CEO of Brother is and lets all get together and sue their miserable corpuscles!

Hope this works for you! I am tempted to go the store and try it on every Brother floor model just to check it out. I may do that and encourage others to do so, just to provide more info to others. I am so grateful to those on this site that have been courteous enough to take the time to respond and judging by the string here, saved many thousands of dollars, or more, for all of us. I am really fired up about this and feel like Brother is really screwing their customers. This is not just a minor issue, this is a HUGE and deliberate misrepresentation. - Anonymous
Hi Edomor..

I added a post (shown as ANONYMOUS, but now I am registered) I am going to copy and paste it here so you know I am responding to you.

Hi ErichP,

Thanks for the helpful missive. Unfortunately, no success :( Mine is a B/W laser, so there are no reset toner options, as you described. only replace drum, that's it. I think the reset toner action is completely mechanical (take out cartridge, put in a new one) and seeing as my efforts to cover the sensors have completely failed, either there is one other sensor I'm not covering (and I've tried all of them that I can find), or they've dealt with this workaround in this release of the model.

Anyone else out there with particular experience overriding the toner end life on a Brother MFC-7840W??

5250DN - when we first tried the tape-over it didn't work. I think this is because we didn't use black tape but just masking tape. Using blacked out electrical tape and now it works.

Brother - if you're reading these posts - which you ought to - I want to say in the strongest possible terms that it is NOT good customer service, nor is it good for your corporation reputation, to engage in what amounts to corporate swindling.

You havn't got an ethical leg to stand on, unless you can explain and prove that it damages the life of printers to go past this Brother-decided point in toner-cartridge use when printing quality is not demonstrably affected. In which case its not a low-toner problem but a design issue which customers are mislead to believe is a low-toner issue.
Not only is it irresponsible in environmental terms (and NO corporation can NOT care about that these days) but (as others have pointed out) Brother is highly presumptuous in allocating (forcefully) the decision to change toner to suit your own interest. It should be bleedin' obvious that these days few customers appreciate having their rightful choices taken away from them.
So, if it as simple as Brother scheming to make more money off unwitting customers by setting false 'low toner' end points, then as far as I'm concerned Brother ought to be prosecuted for systematic swindling.

Works great on a HL-2170W, Many thanks we were in a bind at a remote location. The printer gave no warning the light came on and it stopped printing! This is common for alot of printers - the hp colors have a setting to disregard the ink status and typically give you a 100 more prints

Brett,
Just have to express my gratitude to you and all others in this forum as I just saved $$$ by following your solutions to the "Brother Toner End of Life" problem. Using the tape over the sensor windows, and the reset procedures you described in your 6/23/08 post, I was able to get some emergency printing done on my Brother DCP 9040CN. Upon receiving my toner refill, I emptied the TN-110 cartridge before refilling with the replacement toner and determined that it had over 65 grams of toner left in it! I think these toner cartridges come loaded with like 70 - 75 grams of toner. Talking about highway robbery: With over 85\% of the toner left, the "Toner End Of Life" message appeared and took the printer out of commission. - calellis
Brett's suggestion worked on my 9320 as well. Unfortunately, I had already replaced the three color toner cartridges but have kept them for reuse. Now the black cartridge started giving me "Toner Low" messages (after printing less than 300 copies!) and I just used the reset. Many many thanks.

I, too, would like to know the difference between STD and STR. I set mine to STD but not sure that's what I should have used.
by tooncesmom on Apr 23, 2010 at 4:24pm Add comment
I set both STR and STD on each cartridge, using Brett's process for his unit. I am still on the original black cartridge (another 1000 copies I believe) and I take it out shake it when it starts printing light, and then it keeps on printing. Eventually, I will use up a black toner cartridge. :-) I haven't seen the LOW toner message since doing the remedy.

I have an MFC 8680 DN. The toner cartridge is a TN-650 High Yield cartridge. Been working great and loving it, till now. So glad to find a solution! I resolved both my toner cartridge and drum issues! Thank God for this post! Will save me hundreds of (or more) dollars a year!

I experienced the same toner cartridge issues, and I could feel the toner was at least half full still when I shook it. First, tried the magic marker and scotch tape, then masking tape. Also tried most everything else posted here. Nothing worked, even doing both sides. Then, searched through the house and found heavy duty electrical tape. Did this on the right side only, and it's working great! Have printed several pages PERFECTLY!

Directions for toner cartridge issue:

Right side is the right side of the cartridge when you place the cartridge in front of you the word "Brother" is right side up. The sensor or eye is just behind the blue lever, just behind the white tape that says removing it will void the warranty. It looks like a little glass circle about half the size of a dime, or smaller. Be sure the tape covers it completely, as the first time I tried it, it wasn't quite covered (it's hard to slide the piece of tape down behind the outer plastic part to actually cover the eye, as the tape is very sticky), and it didn't work. And you have to actually cover the "eye", not just put tape over the outer black casing. Second time I tried it, it worked like a charm!

I definitely suggest gently shaking the cartridge from side to side though, just kind of tossing it right and left in a gentle wave motion, as this helps distribute the remaining toner evenly and will allow more evenly dark printing for a longer period of time (used to do this with older machines for months when they would indicate toner needed replacing. Now apparently, they've got sensors to try to MAKE you do it, which totally sucks, as it's just ripping you off when there's plenty of toner left! Someone should file a class action suit!)

Directions for drum life:

As for the drum issue, I noticed while I was attempting to resolve the toner issue that my drum life said it was only 60\%! Which seems ridiculous. I do a lot of printing, but just got the machine a few months ago! So, to reset the drum life to 100\%, with the Cover Open (the one you open to replace the cartridge), hit "Clear/Back". It will ask you if you want to replace the drum. Choose 1 or OK for yes. It will indicate accepted. This will reset your drum life to 100\% (you can check this under the Menu, Machine Info, Parts Life menu.)

Happy with the machine other than this issue. Hope this helps others!

Hi Dreamweaver or anyone out there. Somehow, I was able to figure out how to override the low toner before, but since I used up all my toner, I put in a new one. This new one starting warning me. I thought I applied the tape in all the same places, but it's not working.

I tried following your instructions. In addition, I put tape on more areas that seemed to be sensors. I'm working and need to print, but now it's telling me to replace the toner. It won't print anything at all. It's driving me crazy. Can anyone help me? - Shishu

Just received replace toner replace light after 700 pages on new 2170W. Called brother to no avail. Read this thread and covered sensor opening with tape. Worked like a charm.
Told Brother that the printer settings pages showed 25 \% life left and that there probably was toner left and that the problem most likely is a faulty or poorly designed sensor. They said they would escalate call to level 2 and get back to me in 2 business hours.
Am waiting for call back and I will inform them of the sensor issue and solution and see what they have to say.

Here's another part of the answer: On the Left side of the new toner cartridge there is a little black lever that needs to be in the "upright and fully forward position." (You can move it back with a little tool like a letter opener.)

Once it is upright, it bears against a sensor lever (white) inside the toner compartment.

THAT makes the infernal "Toner Life End" message go away. . . .

Happy days.

Cheers!

Ok all you HL-4070 CDW people...this this works for our little toner scamming maching:
As stated up above for the 4050:

For the toner life reset menu:
1 Open the front cover of the printer
2 press and hold the cancel button
3 press the reprint button WHILE still holding cancel
- here is the reset menu - go to the appropriate cartridge on
- the menu and reset it and you're done!
FYI... Pressing the "Go" button and the up arrow gives you the parts life reset menu (drum, laser, fuser, etc.)

I'm guessing that the abbreviations are:

B.TNR-S means black, toner, standard (next option is B.TNR-H which I assumed meant High (capacity) but if anyone knows different I'd like to know.

Works like a charm.

I hope this helps. I also have the 4070 CDW and found the menu reset for the toner does in fact work, but only until the machine or toner cartridge completely decides it is at the end of it's life. Then I had to try the black tape thing covering over one "eye" only, only until I can get a new cartridge to replace it with. I get nervouse messing around with these things especially because I don't have the change to pay for repairs. It seems to be printing just fine for the moment as I have only had it that way for 2 days now. I hope it doesn't cause any costly repairs as another person suggested. I doubt I'll try removing the 2 screws and resetting the gears. At that moment I'll just have to get a new cartridge. The little bar on the LCD under the black toner has quit blinking so I am thinking the printer thinks that cartridge is now full. I'm planning on paying strict attention to the operation of the printer and the quality of printouts just to make sure my printer isn't failing in some way. I also believe the "S" in toner menu refers to a standard cartridge and the "H", a high capacity. That is NOT my porfessional opinion, though. Thanks again for everyone that has posted on here and gave their thoughts in this issue. :) - Anonymous

I have been having the same problem with my MFC-8890DW with the TN-650 toner cartridge. I just found the solution and wanted to share it. What you need to do is find instruction on how to refurbish the toner cartridge. When you find it use the part of the instructions that shows you how to reset the "reset gear" into it's original position. This link helped me tremendously! http://www.oasis-imaging.com/images/pdf/cart_inst/TN650.pdf

UPDATE: I have an MFC 8680 DN. The toner cartridge is a TN-650 High Yield cartridge. After reading these posts, heavy duty black electrical tape over the sensor hole on the cartridge worked for me about a month ago. So far, I've gotten another 1000+ pages out of that cartridge! However, I did notice that in the past week or so, the toner has started to "bleed" making the entire page look slightly grey and increasingly so as time progressed. The actual print still looks fine though. So, I finally had to put the new cartridge in for "formal" papers that need to look completely professional; however, still using the old one for printing "internal" documents, and it's still going strong! I just swap them out! Definite money saver!!!

I have a brother HL-2070N, How do i get the toner light to stop blinking? I know that there is still some ink left over and i've tried covering the sensor. Maybe I'm doing it wrong? Thanks!

In addition to all toner saving - and using methods, I buy machines when they go on sale to get toner and drums etc.... Pretty sad when you can buy a full printer for less than the replacement cartridges... I see TN110 machines now seem to have TN210 toner cartridges - are these the same?

Well, I initially posted back in November 2009 with my successful method of re-setting my HL4040CDN OEM color cartridges. Today, I had to re-set my black cartridge and I'm glad to report that I have yielded following of my resets on my color cartridges - (OC=Original Count & NC=New Count)total page count: OC=3168/NC=2195, Cyan: OC=1864/NC=2646, Magenta: OC=1892/NC=2659, Yellow:OC=1917/NC=2722, Black: OC=3129/NC=TBD. Theses numbers are impressive - I have averaged about 800 extra color print pages after the display instructed me to replace them because they were "empty" - what a RIP! AND they're not even empty yet! Still going strong.... I will report back when I do actually begin to see signs of low toner. I hope this helps someone.

Hi there
The sensor cover can work but keep in mind that when the final toner message comes up onto your LCD screen, you should change it or you can damage the drum which can be costly, especially if you damage it when you have only used about 30\% of the drum. If a non (toner) powdered roller rubs onto the drum, it will damage it, so there is method in their madness.
Great products - enjoy them.

Brother HL-5370DW owner here.

I am also grateful for this information. I am printing pages with ocassional photos, and the low-toner warnings started after about 600 pages. Covered the "eye" and got another 600 pages out of the initial toner cartridge.

I can understand why the manufacturer would want to prevent running printers completely dry, as it damages the printer drum, and can be an expense to them, if a consumer can successfully persuade Brother that the damage should be covered under warranty. After covering the "eye" you must STOP immediately when you see the streaks and area graying occur. At that point, you are running dry and damaging your printer.

I can also understand the greed of the toner people. Their livelihood is based on fear, since we as ignorant consumers cannot determine the actual toner level inside the physical cartridge.

I reload my cartidges now, although do not assume your reloaded cartidges will last forever, since they have a drum as well, which will die after several reloads. After reloading my first few, and dumping toner all over my carpet in the process, I figured out how to do it, and plan on continuing to reload, buying new cartidges only when the older ones finally die.

Happy printing.

Also found this site to be a boon, thanks for the warning concerning damaging the drum. I was considering going the route of refilling myself. Would you share your knowledge as to a suggestion to where to order the toner and your process to preserve my carpet hue.

Any advice thanked!

Brilliant. thank you very much. after 94 pages my brand new HL-2140 told me no more toner. Black tape worked like magic.

And why did I have a brand new HL21-40? My old one needed a new drum - $110. New printer at Office Depot - no mail in rebate - $49 - including 1,000 page toner.

just a note re old printer waiting to be thrown out. There is a hard drive in printers which has a record of all printed /photocopied material. If this gets into the wrong hands, identity theft is a cinch.

J-CT, I understand what you are stating but couldn't Brother have come up with a better design so that the toner could be used until it is almost empty rather than having the cartridge report it's empty when there's a bunch of toner left??

There are very few home printers that have a hard drive installed. It's mostly copiers that have this problem.

I've had my brother HL-3070CW brother printer for less than a year. I replaced the black toner when the machiene message said that it was out even though it felt (by weight and shaking) like there was still a lot of toner in the cartridge. Now it states that the color cartidges are low. I have now used the black tape method. My question is- Is there any harm to the machine if I were to let the toner run completely out before replacing it?
Shame on Brother for this. It is not very consumer friendly or environmently friendly.

This is from an earlier post made in feb or march 2010. It works. I'm saving money now. i wish i had this before had to change out my starter cartidges and one set of toner cartridges.


Toner Reset Menu for Brother HL3070:

1. Open Cover where you access toner cartridges

2. Press CANCEL & SECURE PRINT buttons at one time and you'll see the toner menus on screen

3. Press + or - to navigate through to the toners you need to reset. Note that each toner has 2 entries here, and I'm not sure why. Would love to hear what each one does, if anyone knows.

4. I'm guessing that the OK button will be the actual reset of the toners, if not then the go button would be I guess, but I couldn't confirm this, since my toners didn't currently need reset.

I also found the reset menu for the durable parts counters:

1. Open cover where you access toners

2. Press GO and + button at once, you'll see menu come up displaying reset counters for drum, fuser, etc.

@ngoat
Absolutely. As was stated earlier in the thread, (assuming your printer is like mine) the drum unit CAN be damaged if the bare, un-coated roller of a completely empty cartridge is allowed to rub on the drum.

Therefore, once you have circumvented the "Toner End Life" situation with tape or whatever other means, it is essential that print quality be checked every few pages and canceled as soon as it is noticed that the color of the now truly empty cartridge is fading.

For instance, if you are printing several sheets of a picture of a big green ball and you notice that its color is suddenly changing from green to blue, that means the yellow cartridge is becoming empty because green is a combination of blue (actually cyan, in this case) and yellow. Cancel the print job immediately and replace the yellow cartridge with a fresh one. (Remember, these printers and their replacement parts are quite expensive! Better safe than sorry.)

HL2170W-took the drum & cartridge assembly out; popped out the cartridge, put black tape more or less alongside the factory sticker with a disclaimer (non-gear side), and PRESTO! there toner.

My guess is that I had printed less than 100-200 pages so far.

Interesting you should state that because just recently I discovered that my HL-4040CN prints in black only if one or more of the color cartridges is empty. All printers ought to work like that.

Unfortunately, I’m unfamiliar with the MFC-490CW. Open a new thread for this issue and see what responses you get.

Second, After the black tape and sharpie didn't work, I discovered a manual on how to rebuild the toner cartridge for the HL2170w. You can find it the panel at this site: http://www.uninetimaging.com/technical_reman_brother.asp

I've been using the original one and finally couldn't get it to work until after reading the manual - I discovered there is no reset gear in the original cartridge (I think I read that somewhere in this blog, as well. HOWEVER, what I did realize is that there is a spring-loaded tab inside the printer that releases when the gear is there and indicating empty toner. I took a piece of tape and blocked the finger tab from popping out (to see if the gear is triggered). WORKS! (although, I still get a yellow check supply level message.

For MFC 7420, the tape over the holes did not work. Still low toner, and I couldn't even scan to email.

There are 3 screws on the left of the cartridge, undo them and carefully remove, making sure the white lever + its half gear (which will not move back) doesn't fall out. Now move halfway back and then reaffix with screws. Voila, normal service resumed and low toner light gone.

Once you re-insert the lever is moved forward again, time will tell how many more pages I get.
by snoekie on Aug 18, 2010 at 7:33pm Add comment
Make sure when using tape or whatever to cover the holes on the cartridges, that absolutely NO light can get through. I wasted lots of time (several days of frustration, actually) and effort trying to figure out why that trick wasn't working on a particular cartridge when it had worked like a charm on other cartridges before.

Carefully examine your cartridge after applying tape. Hold it up to a bright light source while looking through the uncovered window. Can you see light coming through? There should be none. Be careful not to tilt the cartridge too much when performing this test. If you do, toner will obscure the near window and you may be fooled into thinking that the tape has been properly applied to the opposite window.

In my Brother HL-3040CN, I was getting a black line or stripe a quarter-inch thick down the edge of every page of black print.

Brother technical support (Australia) immediately identified the cause of the problem. In the housing for the black cartridge I had not pushed the green slide which cleans the corona wire (which puts electrical charge on the drum) to its homing position on the far left, but had left it 1/4 inch short. - unknown
I have been using the tape over the sensor trick for about one year with no problems. Out of the blue my brother 2140 printer stops printing. Then I get a error message on my computer(which has never happened before) that the toner needed to be replaced. I tried putting in a used toner from my other 2140 printer(which was printing fine) but that did not work either. Is any one else having this problem.

If this thread illustrates nothing else (and it does!), it shows the level of frustration and anger of those who are held ransom to their printers by manufacturers who see the inks as the real money makers.

Give that I am old, ugly and damned cynical, I refused to be dictated to. Even through somewhat of a novice;-I went looking for a fightback! Here it is!!

Other research has turned up the fact that Epson was sued over this in the US. I believe they lost the case..

Research in the UK has discovered that ml for ml, printer ink is more expensive than Dom Perignon champagne!
___________________

For novice Brother DCPC users: (though I know there are a couple of posts above): nothing works except BLACK electrical tape (I've tried). I didn't even know what this was!, but got some yesterday.

Y has been showing empty-it has liquid in it. I checked levels: all showing full ex Y. I remove Y, then simply replace it....

M is now showing 'near empty'! It was full a minute before, NOTHING was printed! (In fact I have allowed this damned thing to show off its red warning for nearly two months because as you all know it would not print!).

Novices: for the 150C just remove the ink, and put black tape over what looks like a mini tape (like you can see in a cassette tape). Cover this with your Etape, with it sticking down to each side about 1". Re-insert. It will resist a bit-but they DO click in. Just go gently.

Now run a test. I haven't a clue, so I ran the Google face page because of its colours! All showing well.

Fading colour ONLY is when you need to buy more ink.

A practically brand new, low use toner cartridge that was full (heavy and could hear full toner) kept saying "out."
Big Brother technical line was absolutely no help because the purchase date was just past 90 days, so they said "you have to buy a new one."
YOUR ADVICE WORKED GREAT! And it works on the 4070CDW as well, just note that that cartridge has two windows to blacken with a sharpie, one on each end, on this model.
Also note: the software in the printer "remembers" a cartrigdge, but you can defeat this feature by performing a factory reset in the printer menu on the printer's LCD screen. BEWARE: Do this as a last resort if you are using the internal wireless feature of this printer and spent a lot of time setting that up as you may have to do that again. Factory reset did not affect my wireless connection because I connect to wireless Apple Express>ethernet cable>printer. I would imagine that a Factory reset on a printer cabled to any brand of wireless hub should be ok as well.
Hope this helps and thanks again.

The fix at the end of this e-mail posted by Rex Anderson worked great for me without any electrical tape. (Thanks Rex!)

By the way, on the 3040, you can print out your ink levels by hitting OK twice, print settings, and go. (Of course, you have to override your settings as listed below before you can do any printing.)

According to this printout, I have approximately 95\% in all my color cartridges, and the printer was telling me I had to replace all three for a cost of over $200.

Yes -- you open the top cover and then hit Cancel and Secure Print at the same time.

This brings up the toner cartridge menu.

You can scroll up and down through the 4 cartridges (2 entries per color for some reason) and Press OK twice for each entry.

The printer will briefly show Accepted for each reset.

After doing this, I am still printing on all four of the starter cartridges and I did not cover any windows with tape or any of that stuff.

Good luck,

Here is an update, Brother has actually caught on to the "black tape" over the sensor bypass, my 6-month old HL-4070CDW has the black tape installed and still hit a "hard stop" due to the Magenta cartridge "being out of toner". I also tried the Factory Reset with no change. I actually had to purchase a new magenta cartridge, install it, let the printer restart, and register a "full" magenta cartridge, then pull out the new one and put back in my still VERY FULL old magenta cartridge and worked just fine. My guess is that the new models must be using some type of RFID technology. People smarter than me may be able to figure a way around this without having to layout the $80 for the tone cartridge..

Same here. My MFC9210CN went through 3 sets of cartridges and ALL stopped at exactly the same time (red flag went up in my mind). On purchasing the 3rd set in 9 months, my Staples manager suggested that I reset the cartridges."What!?"

A quick call to Brother's tech support (10 out of 10 for that) had my cartridges reset in 5 minutes. They did, however, warn me that resetting the cartridges could put the toner drum at risk. Given the whole printer is the same price as one set of cartridges, I was willing to risk it.

Instead of 3 months of printing, I'm now on 5 months & no sign of toner getting low. Probably saved $600+ per year. Otherwise, this is one nice printer. - Mr.Croquet
Covering up the toner window on the cartridge also worked on a Brother 2170W. It seems so wrong that the printer stops printing when it thinks it is out of toner. I couldn't find electrician's tape, so I used duck tape. Thanks for all this information!!

All

On the Brother HL4050CDN (and presumably others that take the TN-150BK/TN-150C/TN-150M/TN-150Y toner cartridges), there are TWO fixes required to circumvent early toner errors:

1. To reset the page counts in the printer, you can use the "Cancel + Reprint" method posted above by Anonymous (posted 5/20/10 10:44 AM). Unless you're printing bulk photos, this will be the first hurdle you hit.

2. Once toner levels are low enough, you'll also need to stick some black tape over the "eyelet" on the toner. The eyelet is the ring made of clear plastic - there is one on each end of the toner, though one is a bit hard to see. I used regular sticky tape coloured in with a black marker. For me, this step fixed error message "REPLACE BLACK(K) TONER CARTRIDGE".

I THINK that removing and then re-setting a cartridge also resets the printer page count, so an alternative to step 1 above is to simply remove and then re-install each cartridge. (I am in the habit of giving each cartridge a gentle, horizontal shake while it's out to level out the toner).

Cheers

I had tape on the sensor on my 2170w drum and it worked for about 2900 pages. Then the toner light just stayed lit. I didn't know about any reset gear, but I saw that there was a little white lever inside on the left. I turned it off, took the toner out, taped that lever in the pressed position, put the toner back in, and turned it on. The web interface said "cartridge error". I figured that was a bad thing, so with it still on, I took the tape off the white lever. Put the toner back in, and it's back to printing just fine.

I've also got the toner saver feature turned on... Gotta say this is one of the best ways I've spent $100, as I've definitely saved that much in inkjet refills.

Hey gang, glad to see that so many of you are having good results saving money and extending the life of their toner cartridges. Thought I’d share an additional bit of info I picked-up over the last couple weeks. When you do as we have discussed to further the life of a cartridge, I have noticed that, after a while, the wiper mechanism begins to deteriorate and the machine starts leaking progressively more and more stray toner onto the printed page.

Whether this is a diabolical plan by Brother to thwart our other efforts, or just coincidental, the fact remains that after you print for another several hundred (or thousand) more pages, the jig is eventually up! Sadly, I do not believe there is a fix for this. In my case, I just keep printing until I can’t stand it anymore or I have a document heading out of house that has to look good. At this point, you will need to swap out the old unit (carefully! …as toner is now want to fly everywhere as the cartridge is removed).

The good news is that use of a new unit completely fixes the issue! While this is all pretty straight forward, it highlights an important issue pertaining to the selection of replacement toners: ALWAYS USE A REMANUFACTURED CARTRIDGE. There are some inexpensive “drill and fill” units out there that, for this reason, should be avoided. The toner will be full, but the wipers and other mechanicals will remain unchanged. It is my concern that if not bad already, these will also soon wear out and copy quality will quickly degrade accordingly. Instead, be sure to buy fully REMANUFACTURED units from a reputable supplier (Amazon seems to have a good selection) that have all such “wear sensitive” components replaced. It may cost more but the unit will likely last hundreds, if not thousands, of prints longer.

Best of luck… and keep fighting!

Brett - Your posting was timely, because I just went through this. I bought my HL-4040CN in February 2009 and it came with TN-110 cartridges; the black was estimated to last 2500 copies. For almost 2 years I've over-ridden the "low toner" messages by blocking the optical sensors, resetting the counters, and resetting the flag gear on each cartridge. For the past couple of months I've experienced more and more toner spatter from the black cartridge. I could solve the problem for a week or more at a time by cleaning the cartridge tray and cartridges with my air compressor, but I finally decided to replace the black cartridge. The old cartridge had printed 6053 pages, and except for the increasing spatter the quality was good. Replacing the cartridge solved the problem. I'll look for a similar "warning" from the color cartridges when their days are up. Hopefully, this will give you some idea of what's possible and what the "time to replace" indications are. Good luck. - Dave - RVdave
A color will use colors to print black print unless you set print properties to mono or B& W. This will save a tremendous amount of color on ordinary test print jobs.
by unknown on Nov 2, 2010 at 8:15am Add comment
My understanding (for the 3040) is that if you use the "AUTO" setting, the printer will determine if there is any colour in the output. If there is, it will behave as described by southwood. If there is no colour, it will just use black toner. But for test prints of colour content, using the B&W setting will definitely save toner. - Notace

Dave, awesome.

Mentioned it previously, but I'll say again that I'm having good luck with "Toner Save Mode".

Access it as follows:
In Windows:

Start Menu > Devices & Printers > RT click on printer icon > Printing Preferences > Advanced > Device Options (5th of the 5 boxes shown) > Toner Save Mode > Enable

Prints on this setting are lighter but I find them sufficient for most of my internal uses.

I am using a Brother MFC-9450CDN. I am trying to do a batch of 500 copies and am amazed that I've already had to swap out brand new print cartridges twice. I thought they were supposed to yield at least 1500 copies! This is costing me hundreds of dollars. Does anyone use this type of model and have ideas on how, if possible, can I re-use these toner cartridges or extend the life of the cartridges??

@bellagirl

That sounds like an awful lot of toner usage for what (according to Brother) is “an AFFORDABLE, network-ready color laser all-in-one suitable for any home office or small/medium sized business...”. Does the document you are printing have large solid areas of color? What print settings are you using?

Something is definitely wrong here.

I tried all of the above and nothing worked until I found a post on Amazon that did the trick and stopped me from exploding ... would have been messy. ]

Here's how to fix the problem (quoted from someone else but it really works... you can Google this problem and it will say to put electrical tape on the sensor, but that does NOT NOT NOT work with this printer. Only this will work):

Toner Reset Menu for Brother HL3070:
1. Open Cover where you access toner cartridges
2. Press CANCEL & SECURE PRINT buttons at one time and you'll see the toner menus on screen
3. Press + or - to navigate through to the toners you need to reset. Hit "Y" to reset the toner. Scroll through and repeat for each toner color as necessary.
4. Hit OK button when prompted.

Reset menu for the durable parts counters:
1. Open cover where you access toners
2. Press GO and + button at once, you'll see menu come up displaying reset counters for drum, fuser, etc.

This unit has stopped printing four times, telling me that I've burned through three magenta toner cartridges. Each time I used this "secret" reset method and fixed it. I'm still on the original magenta cartridge. This "secret" reset method has saved me $200.

On some models Brother uses 3 separate systems to detect a supposedly low-toner condition. They are....

1) A software counter that flashes a low-toner message after a pre-programmed number of recorded copies. This is the sensor you reset with the menu after opening the front of the printer.

2) An optical sensor that will notify you of low toner if the toner in the cartridge gets so low that it no longer blocks a light shining through a hole in each end of the cartridge. This is the sensor that can be stymied by blocking one of the holes with tape.

3) A "flag gear" on the cartridge itself will disable the printer after a certain number of copies has been made. This is to protect the printer against an out-of-toner condition. This gear can be reset by removing the end-cap and repositioning the gear to the start position.

As mentioned in a previous posting, I've performed all 3 of these overrides for the past 2 years and finally replaced the black cartridge (TN-110) after it had produced 6053 copies and was starting to produce some spatter; Brother estimated it would only produce 2500 copies. It's important to remember that ANY one of these 3 systems can cause the printer to assume the toner is low. Good luck. - Dave - RVdave
Got an HL 2170W, had the first optical sensor message after 499 pages (yes exactly that amount).

Covered with tape and now at 2522 pages for the gear mechanism.
Unfortunately I screwed that one up and had to change the printer, and clean up fallen toner :(

Hey smart people!

I need some mega help with my Brother MFC 9440 printer. It says the Magenta is out, even though I can clearly see more powder still left in the cartridge. I tried covering the eye holes up like previously posted, but I think this newer model is too smart for that. Any suggestions/tips?

Thanks so much!
by unknown on Nov 19, 2010 at 8:52am Add comment
As has been repeatedly discussed, the optical cartridge sensor is only one of THREE "low toner" warning systems used. Covering the cartridge "window" isn't going to help if it's the printer's software copy counter that's generating the message, or if there's a flag gear that's reached it's stop. Answers and solutions to all these possible culprits can be found on this thread. Good luck.

@Sparkleojoy When that magenta really goes, make sure you replace it with a genuine Brother magenta. Otherwise your prints may look drastically different. If you go purchasing some generic cartridge, you may be unpleasantly surprised. What should be deep red may come out almost orange! A word to the wise.

worked fine for lexmark c500n (as mentioned by another user before):

a brief introduction as boons like me need it :D

1. open front lid
2. take out any cartrige
3. at the bottom of its rail there are 2 diods
iirc a red one on the left, a tranparent on the right
those are to be covered with tape
4. go to 2. for other cartriges :D :D

I have a Brother HL 2040 and a Mac. Nothing worked, so I called the number for Brother posted above. They had me try covering the lenses with post-its which didn't work. He said if that works it means the toner actually is low. Then he had me press 'Go' three times, and a sheet entitled "Print Settings" printed out. Obviously the toner was fine. Then he had me uninstall and reinstall the printer (Apple icon; Preferences; Printer & Fax; then - and + signs to uninstall and reinstall printer.) That worked!!

On the brother HL-7040CDW, the electrical tape thing did not help me. I left the small tape bits in place, however, while I did the reset.

The tip is great -- you have to hold down the reset and cancel buttons while you do the reset. You have to cycle through the cartridge options, because it has one for H (high yield) and for S (standard) for each of the colors.

This has worked YAY! Stopped in the middle of printing a report.

I will get new cartridges to ensure print quality, but it makes me crazy how this unit a) gives you NO warning and b) stops all three color cartridges at the same page count.

I switched from HP, and am finding this really irritating -- the HP always gave you lots of warning before it stopped.

I give up. I have a Brother MFC-9440CN and I have just replaced the toner cartridges for the first time. The "Toner life end Replace Magenta and Yellow cartridge" message stays on and the machine won't operate. I called Brother and they won't talk to me because I didn't buy Brother cartridges. For reference, I won't be buying any Brother products ever again.

I looked on this site and saw references to putting a piece of electrical tape on something somewhere. That doesn't seem right to me. If I'm trying to fool the machine into thinking I have new cartridges-I HAVE new cartridges.

I followed instructions in one posting about resetting. I opened the front door, pressed Clear/Back, then set each color to High. I closed the door and got the same error message.

Anybody like to buy a doorstop cheap?

This rocks!

To go into an UNDOCUMENTED maintenance mode on the MFC-685CW, hit Menu > Black Start > Menu > 76 > 3 > Black Start.

This power washes the print heads by forcing a larger amount of ink through the orifices than the normal cleaning cycle listed in the users guide.

I had all 3 color head clogged and I used this procedure repeatedly to unclog them.

Hi amazedprinterman. Changing from Brother to another manufacturer won't help. They all do the same thing: sell you a printer for virtually nothing, then gouge you with the cost of consumables. It's the same for inkjet or laser printers, and is basically the same model used by Gillette, Schick etc., when selling razors/blades. The only way to avoid this is to use clever tricks like this one. Happy printing!

RVdave, Thank you for your note on the three separate low-toner detection systems on Brother machines. I personally have used all three of them with great success. At the office, we have a Brother MFC-9840CDW. At home I have a Brother 4040CN (I think. I'm going by memory here). I'm not an expert at all but have had success. Two examples: 1) At home my yellow toner kept giving me the toner life end notice. Using all three bypasses, I extended it's life significantly. Finally, I was frustrated with not being able to bypass it anymore. So I opened the cartridge to see how much toner was left. It was bone dry. so these fixes do work. 2) At work I have the same result. I only made one large mistake though. I was getting splotches of black or yellow or red toner. I would take the drum unit out and use compressed air to get rid of the excess toner. I sprayed the toner rollers off and actually had to rub off some excess toner off the red drum. Now I get red streaks and smears all the time and print quality really sucks. From what I have read here, I'm sure I damaged the drum. But, it has 18K copies on it, so it's probably due. I have had to reset the drum counter once already.

StevenDH - Glad to hear that the 3 possible over-rides are working for you. After more than 6000 copies, I finally had to replace the black and yellow cartridges because of excessive spatter, which must be a symptom of being low on toner. Another way of telling if you're getting close to being totally out is to look at the cartridge roller. If the roller doesn't have an even coating of toner, it suggests that some areas of the cartridge have little or no toner. In this case, slightly shaking the cartridge from end to end will sometimes even out the toner in the cartridge and buy you some more copies. Of the 3 over-ride solutions, resetting the flag gear is probably the most difficult, and the next time I have to do that I'm going to simply remove the flag gear and see what happens. I don't expect that to be a problem, since some starter cartridges don't have that gear. If anyone has done this, please share your experience. Thanks, and happy holiday. - RVdave
by RVdave on Dec 21, 2010 at 10:05am Add comment
After reading a few of these posts about resetting the flag gear, I just wanted to give you a clearer idea of how it works.
If you have a black printer, you can usually print a report that shows page counts and # of toner and drum changes.
I have been refilling Brother toners for about 10 years now.
What the flag gear does is reset the counter as soon as it goes in.
It does not as indicated by one of your posters slowly wind down.

They are very easy to reset, in fact the older TN 2000/2025/350 type cartridges you just hold it upside down use your thumbs to gently wind the roller backwards(at the edges) and use your finger to move the gear back as you wind the roller.
In some cases it just winds back by itself.
Then install the cartridge and as long as the window is blocked (its easier to block on the drum) it will go for 2500 pages based on 5\% coverage.
The newer models require 3 screws to be undone as brother got smart and put a notch in the gear which stops the above method.
The flag gear will then be removed with the side cover and can easily be repositioned.

Hope this makes things clearer for people.

I read one guy saying he is going to throw it out when the toner runs out.
Not a very bright spark!!
HP, Canon, Lexmark etc have chips to monitor levels and Samsung now have a chip built into the machine to stop refills.
So far Brother are the easiest and most economical printers in both ink and toner for refills.

Happy New Year to everyone.
by unknown on Dec 26, 2010 at 11:29pm Add comment
Captain1 – Thanks for your input concerning the Flag Gear. You indicate its purpose is to reset the counter. I’m curious if you see any problem with removing it, since it isn’t included on Starter cartridges and is only added when the cartridge is refilled. It's a lot easier to reset the counters with the control panel instead of having to disassemble the cartridge to reposition a Flag Gear. Perhaps on models where the counters can't be reset via a control panel it’s more necessary.

Previously, another tech indicated that the Flag Gear’s purpose was to gradually increase the voltage as more copies were run, to compensate for excess toner returned to the cartridge that may have lost some of the properties necessary for proper attraction to the drum. I doubt this would apply to printers such as mine (HL-4040CN) which returns excess toner to a separate container instead of the cartridge.

I agree with you that it’s easier to block the optical sensor by blocking the holes in the drum carriage. Instead of tape, I use those plastic buttons sold in auto parts stores to secure trim.

Thanks for your help, I suspect we’re living on borrowed time regarding these over-rides. I’ve saved more money not replacing cartridges than the printer cost, and I have to believe that Brother follows these threads and will make design changes to prevent this in the future. Good luck. - Dave

I would love to know what to do about the 2270DW as well--I got well under 500 pages out of the supposedly 700-pg starter toner cartridge, and I know there's more in there since it is still printing dark black, but it has no obvious spot for a light sensor. Seems like perhaps Brother caught on to the tape hack when they designed their new cartridges. - unknown
go into control panel (windows)
select devices and printers
right click on your printer and select properties
select web services page
click on http link to your printer control panel
choose printer settings
use admin as username
access as password
change many default settings
in this case replace toner continue

no electrical tape needed!!!
- ragette
To get the max amount of toner without Brother premature shutdown of printer, press "GO" button 7 (Seven) times. If this does not work, shut off printer and try again. However, note that if you press the "GO" button 7 times and nothing happens, and then do it again, it will RESTORE the Brother toner shutdown, so you must do the whole routine once again. - craigkay
WOOHOO!!! Second time now my hl-3070 says out of cyan toner and then magenta. Did the open top thing, cancel and secure print together, press OK close the lid and back in business!!! Thank you ever so much for protection from this rip-off (oversight?)So far saved $1000

Colin - Thanks for the update, that was interesting.

Look I'm just a simple girl and you all are ingenious. I took a big guess at what the sensor was, covered it with tape, put it back in and crossed my fingers. IT FRIGGIN WORKED!

By the way, the sensor on the "non gear side" is sort of a clear circular indented cap. It's on both side, but one side is covered with black end cap (if you will) over the whole thing. That doesn't make any sense does it....

So I've had this extra toner sitting here waiting to be installed whenever what I've got runs out and now it's going to be waiting a while longer.

I'm very grateful! Now who can help me get this byotch back to printing wirelessly?!

Kate - If you look closely at the cap, or gear, side of the cartridge you'll notice a small 1/2" slit just below the cap that the light can shine through. You'll also notice than the carriage holding the cartridges has a hole on each side that lines up with the cartridge windows. Some of us prefer to cover the carriage holes instead of those on the cartridges. That way you won't have to reapply tape if you ever change the cartridges. Good luck. - Dave

Accessing the Brother HL-2270DW "Printer Settings" page via a web browser pointed at the printer's ip address on one's local network permits one to change the "Replace Toner" mode from "Stop" to "Continue". This allows printing again without having to tape up a sensor hole. - unknown
I have this printer..apparently Brother has listened to complaints because all you do is hit the go button 7 times and it will go into continue mode. You do this when the toner light stays on then you will get a toner light and ready light...this is in the user manual and it works great...I am still printing on my original partially filled toner cartridge - unknown

I came across this site because I researching a way to fix my printer. I installed a brand new OEM Brother TN-210C (cyan) cartridge and yet my relatively new MFC-9320CW indicated I was STILL out of Cyan. I decided to go with the printer override function on the computer rather than cover the scanner eye because the solution seemed more elegant.

So I used the advice given by "Anonymous (4/9/10 10:09 AM)," based on BrettSoCal from 2008. I reset both the STR and STD settings for my cyan cartridge, and it worked. I tried a test sheet of blues greens and purples, and they printed marvelously.

Suspecting that I had been conned by my machine, I decided to go back and re-install my TN-210 magenta and yellow cartridges, which I also had recently replaced. (Luckily, I had not yet sent them back to Brother to be recycled; sadly, I had already sent back the black one.) I re-installed the magenta and yellow cartridges and reset the toner monitor as described by Anomymous. I then printed a test sheet of a bunch of colors that have yellow and red in them. Perfect!

In short, this solution worked for me. I don't know how many more pages I will get from these cartridges, but every page will feel great because I have already invested the money in replacements.

Brother, I love your printer, but your toner fraud is ridiculous!

Next, I removed the screws from the gear cover and tried to determin what the "flag gear" is. There are 4 gears with this toner cartridge. I don't have a clue which gear does what. Any suggestions?

black tape works with brother MFC 5460CN. It works with all colours apart from yellow. Not sure why. Put the right over the little window in the middle of each ink cartridge - covering right around.

Might need yellow tape for yellow perhaps, or red tape.

Printer is printing fine - quality is great, just goes to show that the ink hasn't run out yet, which is shameful in this day and age of recycling and reusing, glad there are people out there willing to figure this out. Its not just about wasting money but wasting resources too.

I have a brother mfc 7840w

I first used the electrical tape trick and that worked for a while. Then got the toner low message again. I then tried the *00 trick, which works as follows:
1. lift lid and open front cover
2.press clear/back. "Replace Drum?" will appear on the screen.
3.Press "*00" it will then read accepted and the toner low error should go away. Thanks for all your help guys.

Where, exactly, is that sensor on the Brother HL 2270 DW laser printer..or on the /tn420 cartridge? This is a reasonably new printer in January, 2011. The cartridge is a "starter," but it also provides a very low number of copies. Thanks

@ rpolhill
The HL22xx series doesn't have an optical sensor anymore. The machine counts the rotations of the developer roller. You can put the machine into "continue mode" in case the toner led is on. Push the go button 7 times and you can print until the tonerunit is fully empty :-)

Thanks so much - nearly in tears but now its fixed. Happy again. Just installed a refilled or remanfactured cartridge . Will I just keep doing this until the print fades to nothing?

I tried this on my new 2270 but it didn't work. I was still using the starter cartridge. Do you have any suggestions? - praterteaches
I have a HL 2240. I read a post about pressing the go button 7 times and it WORKED! Mine did not have a sensor on it by the way. I am printing again! Thanks!

Can someone please explain where exactly is the hole that should be covered on a TN-210K cartridge? I have taken this cartridge out of a Brother HL-3070CW printer but I am not able to find the hole.
by unknown on Mar 13, 2011 at 12:25pm Add comment
look back through the forum. the reset procedure for the 3070cw has been posted twice that I know of. here it is again for the third time.

Toner Reset Menu for Brother HL3070:

1. Open Cover where you access toner cartridges

2. Press CANCEL & SECURE PRINT buttons at one time and you'll see the toner menus on screen

3. Press + or - to navigate through to the toners you need to reset. Note that each toner has 2 entries here, and I'm not sure why. Would love to hear what each one does, if anyone knows.

4. I'm guessing that the OK button will be the actual reset of the toners, if not then the go button would be I guess, but I couldn't confirm this, since my toners didn't currently need reset.



I also found the reset menu for the durable parts counters:

1. Open cover where you access toners

2. Press GO and + button at once, you'll see menu come up displaying reset counters for drum, fuser, etc.



- Tumbleweeds
So I pushed the button 7 times and it worked for 2 days and then quit again.

Instead of the tape I just used a black sharpie to fill in the clear cover where the sensor reads the low toner and that worked. I only did it on the non gear side. Its not giving me a low toner reading anymore.

HL-4150cdn : Hack the toner counter! Open cartridge door and then press both "cancel" and "secure" buttons simultaneously. This will take you to a hidden menu where you will find 3 counters for each of the 4 toners. That will be 12 counters in all. Reset each one and you are back in business making your hard earned dollars stretch 20-40\% above what Brother planned for your dollars. Shame on Brother for doing these HP style tactics! I dropped HP after selling and installing nothing but HP printers for over 15 years. HP quality went in the dirt and the drivers were terrible resource hogs that would cause all kinds of problems. Mostly because they used Microsoft .Net crap. I have been very happy with Brother printers and especially the low overhead print drivers. But this really ticked me off when my clients started having to replace toner when it was still nearly half full. I am sure glad someone started this thread! Cheers!

The *00 trick also works on the MFC 8480DN. Taping the sensors did nothing, but then I opened the cartridge door, then pressed "Clear/back". "Replace Drum?" appeared, then I entered "*00" and the toner worked again. Thanks for the tip.

A big thanks to "jdelancey"!

I have the Brother MFC-7340. I was getting a low toner message and had to do the following to make it go away:

1. Open the cover.
2. Remove the drum/cartridge unit.
3. Tape the sensors inside the printer on both sides with electrical tape.
4. Put the drum/cartridge unit back in.
5. With the cover still open, press the "Clear/Back" button.
6. When asked to "Replace Drum?", press "*00" on the printer key pad.
7. Closed the cover and I was in business.

Thanks everyone! - rashiki
For the high capacity cartridge, the black tape over the holes did not work for me.

I did the flag gear reset, which is at the left side, top right, a white gear. Remove the two screws and reset that gear - worked for me.

Google "tn580 flag gear" since I cannot copy the google result link found below. See also various posts in this forum on this.

This is the new printer hl2270dw and TN420 cartridge. Thank you for those who suggested hitting "go" 7 times it worked. Now the caveat is when the toner really runs out how do we go about refills. Any brilliant minds out here who can suggest how not to send cartridges to landfills and refill the new TN420/450. Thanks for reading. Sandy

Hi there,

I changed the network settings from stop to continue and then I pressed the go button 7 times but it still would not print. It printed out a network configuration sheet instead. I tried restarting the printer and network and when I did that my printer does not appear on my network anymore. Got any ideas???

Thank you so very much, I have recently purchased my mfc-9320 cw and was very disappointed at the count so far. I did go out and replace the black begrudgingly, but now it wants the colors replaced which just are not in the budget right now. I can not express my gratitude for this info. Thank you is all I can say, I am looking forward to seeing how many more prints I get.

This thread is awesome! I applied tape on right side of the cartridge where it has transparent eye on Brother TN360 toner.

Have a HL-40C Color Laser, printing just fine then: "Tone Life End Replace Cyan, Magenta & Yellow toner Cartrige". Tried tape with black marker, no change. Any suggestions?

I think my computer is actually an HL-4040CN. Anyway with general help from above thread got it fixed. What I did: Removed 2 screws from the plastic end cap of the Gear-End of toner cartridge. Then lift 1 small plastic tab on top of end cap to remove end cap. Lift tension spring wire off Gray plastic gear piece - this seems to be a mechanical stop. Lift the Gray plastic gear piece out if its gears and rotate it about 1/4 turn CCW and set it back into its gears. Set the tension wire back on to it. Snap the end cover back on and replace 2 screws.

You will have to do this for each Toner cartridge the Menu says to change.

Works great! What a major ripoff! END OF LIFE? More like beginning of profit stream.

Much appreciated. I am back printing again. I was not happy with the number of copies it printed so had not purchased new cartridges or toner. Great info.

HI GUYS,
Did it again for the third time! Now up to at least 1000 sheets on the same cartridges which only gave me 200 to start. No lines, no fading, nothing but good copy. This is with the fix for an HL-3070 W for which I first bought a black toner cartridge unaware of the "fix". Thank you, thank you, thank you for this thread.

Haven't read all the posts here - just came because my toner "ran out". After reading about putting tape on the reader (and not having any electrical tape at hand), I inked over the recessed camera-eye with a magic marker. Works like a charm for my Brothers MFC7220. Thanks all.

For the MFC-9560cdw, to reset the "replace toner" message and allow continued printing,
1. Open the front door as if you were going to change the toner cartridge.
2. With the front door open, press the "menu" button to bring up a reset menu
3. Scroll to the toner cartridge that you want to reset and press "OK", then "exit"
4. Close front door and wait while printer resets itself.

I have a Brother HL-4570CDW and the black tape trick works. Eventually, though, I do have to reset the printer to detect new (or existing) toner cartridges to get the bloody "Replace Toner" message to turn off so I can print. This reset procedure is not published in any Brother support documents or manuals. I had to call their support team and threaten to return my non-functing printer under warranty to get this info and they made me jump through a bunch of hoops, including providing proof of purchase for my genuine, Brother toner cartridge - what a crock. Open the front cover (toner bay). Press the "Cancel" and "Secure" buttons simultaneously until you see the "reset" menu appear. Press the "OK" button. Press the 'up' arrow and note the word "Accept". Press "OK" again. You're good to go. Note: another user on the Web has posted that you hold down the "Back" button and the "Cancel" button simultaneously to reset the HL-4570, but that did not work for me; maybe Brother is changing this procedure with each firmware update to foil us users into having to prematurely buy toner. I see a class-action lawsuit in Brother's future for manufacturing printers that don't operate when toner is still viable.

I had to fool around with which buttons to press for my HL-4570CDW, but "Cancel" and "Secure" pressed together with the toner door open took me down the right path to get rid of those pesky messages. I had to try different cartridge selections as well. My printer is working fine now. I will keep printing until a cartridge actually runs out of toner. Seeing that the printer works fine, I WILL NOT UPGRADE MY FIRMWARM unless the printer actually ceases to function. Thanks for posting your reply. FYI - the black tape did not work for me. - MikeL77
I have 3 Brothers - HL-2270-DW, MFC-8480-DN(All in one), and a HL-4070-CDW(4 color cartridge). For the life of me I cannot figure out what hole gets covered with tape or which side of the cartridge those holes are located. Can anyone help? Do these printers have this type of cartridge that can be faked? Is it only OEM cartridges or remanufactured, too?
Thanks in advance for any help - I go through toner like water.

I have the 2270DW that works really well, but I can't figure out how to extend the life of the cartridge. I have tried pressing the go button and setting the printer settings on continue and it didn't work.

Help! I've been using this printer for almost two years and have been able to overrride the low toner until just recently. The last batch of OEM toner cartridges I got run out after only about 1,000 pages, the toner light comes on and NOTHING I do can get it to print more even though I can feel the weight of the toner still left in the cartridge. I have done the tape, I have reset the printer.....anyone have any ideas?

Thanks!

What is the exact model # of the cartridges you have. Not the printer. The cartridge model number looks like TN-XXX. Also is the cartridge a real OEM Brother replacement, not a starter or aftermarket? You can email me directly at [email protected]
