Hi there
You can reset the brother dcp 9020cdw toner cartridges using the printer menu. Its simple. see video on the link

When the toner cartridge is exhausted or empty then theprinter will not be able to print further documents or the prints will be veryfaint. You may be able to print a few more pages by removing thetoner cartridge and shaking the toner cartridge in a horizontal position a fewtimes and then placing it back into the printer. This will give you an opportunity to print a few more pages and giveyou time to purchase a new toner cartridge for your printer. A cheaperalternative is to purchase a re-manufactured toner cartridge for your modelprinter. A re-manufactured printer cartridge also replaces worn partsas well as refilling with toner powder.

What worked for me was to follow the instructions in this video: Resetting lever on cartridge There is a lever on the left hand side of the toner cartridge (left hand side - with you holding the cartridge as if you were going to insert it into the printer). It seems that lever has to be at the '12 o'clock' position to tell the printer that you have a new cartridge. The video showed the person removing 3 screws and then ensuring the lever was at the '12 o'clock' position. On my cartridge I had to do some wiggling to get the lever to move as it's gear assembly seemed to want it to only move down to the '4 o'clock position' and then stay there. Eventually I got it moved to 12 o'clock - and when I stuck the toner back into the printer - the 'toner end of life' message went away. I then removed the toner cartridge - as I wanted to try another cartridge that I had also reset the lever on. I found that lever had again moved to the 3 or 4 o'clock position - after printing just one test page so I am guessing it being at the 12 o'clock position tells the printer you have a new cartridge - and then it moves over to the regular position at 3 or 4 o'clock..

> toner life end

Replace (not refill) the toner-cartridge.

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

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

When you refill the toner cartridge you have to reset the chip on the toner, otherwise the printer still sees it as empty.

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

hi just replace the toner
thanks

Is this a remanufactured/ compatible unit? I suspect that the toner reset lever on the cartridge has either not been installed or not properly set. return for another one

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.
