With the front cover open (where the cartridge is installed), press the clear/back button then press star 00 (*00), then close the cover.

Brother printer MFC 7440 N says to replace toner and I already did


Did you insert a brand new toner cartridge or refill only, if you insert a brand new they read your toner cartridge, if you insert a refill toner cartridge, first you need to reset the toner cartridge, i think in the right side, or left please switch and back to normal position.

BROTHER DCP7055 PRINTER SHOWS REPLACE TONER EROR


When replacing the toner cartridge, you MUST install a brand new, unused genuine Brother toner cartridge in order to reset the toner status. Swapping toner cartridges from one machine to another or installing a partially used toner cartridge may cause this problem. Brother machines control their image quality for the most suitable print quality by monitoring toner consumption. If you install a partially used toner cartridge, your Brother machine is unable to recognize toner consumption correctly which will cause this problem. Therefore, when you replace the toner cartridge, please use a brand new toner cartridge, not a partially used toner cartridge from another machine.

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


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

I have a Brother MFC-7440N machine. On 7/22/10


The toner cartridges have a small port on the side that the printer uses to check the toner level. Our 7440N tells us it will soon need a new toner cartridge and will then print another 400 copies. Search YouTube for Brother Toner Cartridge and it will show you how to modify the cartridge by covering up the portholes with tape. Since there is obviously some kind of sensor, you might need to get a can of air and clean out any extra toner. Lastly, the Brother cartridges have "reset gears" which are replaced when the cartridges are refilled. You might have a cartridge which the gears were not replaced on.

I have a Brother fax and copy machine and have just replaced toner with a brother TN 350 cartridge and still getting message that toner is low


You didn't include the model, but here are instructions for the Fax-2820; it should work for any of the models that use the TN-350 toner:
  1. With the power on, open the front cover.
  2. Press the Options key. The display will read "Change Drum?"
  3. Press Start.
  4. Press 1 0.
  5. The display reads "Accepted" for about 2 seconds, then change to "Cover Open."
  6. Close cover. The "Replace toner" message should be cleared.
Normally, inserting a new cartridge (with the power on) will reset the toner counter, and you won't have to do any of this.

Change of toner


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 (End of Toner Life) should go away.
4. close it all up and your done.

Toner life end


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

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


Hope one of the above works for you
Thanks J
