Toner life ends

The problem with this is the design. Each toner cartridge has a microchip on it, that counts the pages you print. The company has determined that you get x amounts of prints. Then you have to replace it, empty or not. This printers do not work the same way as an expensive professional business copier. In an pro style there is a spent toner cartridge that collects all of the wasted toner that is on the drum. On a small business/home style this spent toner goes back into the cartridge. There is no level indicator, even on the inkjet printer. They too, have a chip that says you have x amount of prints/cleaning cycles they can go through. Look up inkjet refill kits or inkjet cartridge programmer.

your drum unit is near end of life.
you will have to buy something like this

i am showing you just for example, search local stores for cheaper.
you can also give it for recycle, just find some toner refilling company near you.

try this. open the front cover, press the "options" button, then "start", then "1" then "0". once you see the message "close front cover", close it. if message comes back, you may have a faulty or "refilled" cartridge. if toner cart is not "reset" properly when refilled, you will get this message also.

good luck,

If you want to reset your Brother MFC 9440N machine so you no longer have the error message: Toner End of Life, do the following:

1. Open the front cover of the 7820N, that is, the cover that allows you to pull out the toner and drum, but don't pull out the drum/toner.
2. Push the button: Options (located on the left of the control pad).
3. Type: *00 on the keypad.

The Brother MFC 9440N should be reset and the Toner End of Life message should disappear. Warning, this may void your warranty and ultimately damage your machine if you are reusing or refilling your cartridges, but you should already know that. Hope this helps.

I found the following post on another site. It appears to work. If you want to reset your Brother MFC 7820N machine so you no longer have the error message: Toner End of Life, do the following:

unfortunately the drum within the cartridge has reached end of life so changing to a new drum cartridge would resolve this issue.

we can refil toner many times but we should reset cartage, while we refiling toner to open cartage we should sides white rings middle plastick flate white plate make adownof cartage it is first methode. when we put reffiling cartage put on printer and do on at that time we push cartage right side pointo re set. look on www.brother.com

When the Toner Life End LED flips on, requires you to replace the cartridge, even when there's still toner left in the cartridge. The machine detects end of life by shining a light through from one side to the other.
To circumvent the detection mechanism, remove the cartridge and put a piece of masking tape over or jam a little bit of paper into the clear opening/circle on the right side of the toner cartridge, and then pop the cartridge back in. Eventually, you'll start seeing streaks, and then you'll know that the cartridge is truly empty.

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.

open front cover, press OPTION button, on the LCD will appear a message "NEW DRUM?" ....DO NOT RESPOND....just type on the keyboard "*00" and there will appear a message "Accepted" and use it in your pleasure.

PS. in any case i blocked with paper labels the viewing windows from transparent plastic on the toner itself....

Mr. Brother, do not try to be smarter than your customer
