Question about Brother MFC 7420 All-In-One Laser Printer

1 Answer

Message on Brother MFC 7340 is "Toner Life End.Replace Toner cartridge". Plenty of tone in cartridge. Inhfact, I just installed a compatible cartride unit which works fine on a Brother printer. The message: "Toner near end of life" had been a previous nuisance.

Hello,

Open door
press Clear/Back key
press *00
press OK

Do not choose anything for drum replacement. when drum replacement menu comes up, just press the * and then 00, then just press OK.


that should clear the error message, the printer has a toner life counter that needs to be reset.

Drum Life Ends soon - Brother


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.

Error message "put the black toner cartridge back in"


I got this same error message on a newly acquired Brother DCP-7040 that I purchased used off of ebay.

As I was troubleshooting this unit (that I bought untested off of ebay - hey gambling has paid off handsomely for me many times before!), this error message kept popping up.

I checked the COUNTERS (page & Drum life) and found out that the DRUM had 0% life left. BUT, the reason it showed ZERO was because this unit did not have any drum! The toner cartridge (TN-360) needs to sit WITHIN the drum (DR-360) on this DCP-7040 unit, as well as in models DCP-7030, MFC-7340, MFC-7345C, and MFC-7440N.

So perhaps some of these "put the black toner cartridge back in" problems could be related to the DRUM (or lack thereof). A possible tipoff (since the toner cartridge actually does slide into the unit much like other units that do not use Brother's DRUM carrier) seems to be the relative ease with which the toner cartridge slides into the DCP-7040 and really doesn't seem to "lock" into position real firmly.

Does the 'Drum Near End' message for MFC 8460N mean to indicate the toner cartridge needs replaced?


Same with our Brother 8640N, drum near end means toner is nearly to end but sometimes even you replace bew cartridge is appears this message. TONER LIFE END message need to replace cartridge.

I have the MCF 7340. I am getting a message - End of Drum Soon. So, I bought a new drum ($120) and installed it. Now it says Drum end. and won't print. Ive turned the machine on and off several times,...


If you open the front cover of your printer where you install the toner cartridge and press the "Clear/Back" button with it open, an option comes up on your LCD Display that says "Replace Drum?" press 1 to reset it. That should fix your problem!

How to get ride of Toner life end message


You could try resetting the toner cartridge settings. OPen the machines front door where you would replace the cartridges. On the top panel you will see a "clear/back" button. Press it and on the display you will see a reset menu come up. Arrow to each one and hit the OK button. Press "1" to reset. Once you have gone through all close the front door of the machine and press stop to bring the display back to normal.

Hope this helps.

I REPLACE THE TONER CARTRIDGE BUT ON LCD IT DISPLAY MESSAGE TONER LIFE END,OPEN FRONT COVER AND REPLACE TONER CARTRIDGE


Is this a genuine Brother replacement cartridge, if not you may find that it is not recognised by your MFC. Also worth a try is removing and reinstalling the new cartridge ensuring all protective packaging is removed. Also remove and reinstall the Drum unit as Brother actually recommend this as part of a new toner install

MFC 8460N giving Toner Life End message


I just solved my own problem. Try it for yours. I had been using several compatible toners for the MFC-8460N with no problems until today, as I posted earlier. On a hunch, I went to the local office supply store and purchased one original Brothers TN550 toner and put it into the printer and closed the cover. Everything clicked. Toner End Life message gone. I then took that Brother toner out and put the compatible one back in and still everything was fine. Am keeping the original Brother toner as a "kickstarter" if it happens again.
