After replacing the black toner with a new Brother TN04 cartridge, the printer still reports that the toner is out and needs to be replaced.

Is there a way to get rid of this message?

    I have the exact black toner for my BROTHER mfc 9420CN but the message is still there toner out. Is there a reset button?

    Same problem. Screen stating "toner low k." K is Black so I replaced it with a genuine brother toner cartridge. Message is still displayed. Trying lightly shaking it side to side and flipping in over in opposite directions, still nothing. I've also shut the machine off, much to the distaste of my coworkers, for 10 minutes. Turned it back on and still the message appears. Tried to press 3 and 9 to go into the reset menu, and it just beeps at me.

Are you sure that it is not asking for one of the colour toners?

Was it a genuine cart?

Did you replace it before machine instructed Replace Toner ie no message or Order Toner/Toner Low was displayed?

My brother DCP 7055 shows eror replace toner

Some Brother laser printers have separate consumables - the toner cartridge and the drum unit. From time to time you may need to replace only the drum unit and not the toner cartridge.

The error LED lights up, or an error message shows on a flat screen panel, when the drum unit is near the end of its working life. Use the drum unit until you have a print quality problem, then replace the drum unit with a new one.

You dont say what model it is but in 90% of cases with the brother printer, it is the fault of the toner cartridge. I am presuming that the toner cartridge you put in was a generic brand. On the left hand side of the toner cartridge there is a counter reset lever that needs to be in the correct position to reset the printer. You can either return the toner cartridge and request another or try to reposition the lever & gearing by taking off the left cover.

Brother 2140 toner light on, won't even try to print.

To get every bit of toner powder out of the cartridge, first remove the toner unit from the drum assembly. Second, find the little circular window on the right-side of the toner cartridge. Third, place a piece of black electrical tape over the clear window, cannot be clear tape. Fourth, re-install the toner cartridge into the drum assembly. Last, put the complete unit back into your printer. This worked for me.

HELP! Brother MFC-8460 "Toner Life End" won't clear

The problem with a new toner cartridge that will not signal the printer that it has been changed has to do with a gear positioned wrong on the new or rebuilt cartridge... we had 3 factory brand new toners that would not clear the replace the toner message... I finally found the following link that came from a toner company that sells refills that tells how to reposition the gear to let the machine know a new cartridge has been installed. I did the proceedure on pages 5 & 6 having to reposition the gear and all cartidges then worked flawless... it works.
