I would suggest downloading a copy of the user manual for your printer -it gives step-by-step instructions as well as detailed pictures to follow to remove the toner cartridge from the drum


Here is the link for the user manual for the Brother MFC-7420 All-In-One Laser Printer:

This is a .pdf file-You will need Adobe Reader to read the manual.

Once you have downloaded a copy of the manual to your pc, Go to Section 11-25 (p. 112) and 11-26 (p. 113)  Here you will find detailed step-by-step instructions and illustrations on how to remove the toner cartridge from the drum.

Reset 7470d cartridges


Not sure about your model, but it is nearly always in the menu accessed through a button on the machine. The MFC 7420 does it this way:
Switch printer on
Open front cover
press "Options"
Then enter "*00"
Should then see message saying toner counter reset

For the brother mfc 7820N the toner life end pops up and i have tried the *00 to reset and it doesnt work. What do I do?


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.

Brother MFC-7420 just started printing a shadow image


Sounds like a bad drum cartridge. Pull the toner/drum cartridge out of the machine and set it down. Press down on a (blue?) tab to release the toner cartridge, and you can lift the toner cartridge out of the drum cartridge. There is a cleaning blade in there - a soft plastic blade that rides against the drum and scrapes off toner that didn't get transferred to the paper. If it gets stuck off the drum surface, images repeat a few inches (one drum circumference) down the page.

A new DR-350 drum unit should fix it. have the machine's power on when replacing it. While the door is open, touch the CLEAR key. The display will read "REPLACE DRUM?" or something like that. Press 1 for Yes.

Remove the drum and toner (cartridge), look inside the machine, there should be a piece of paper, remove it and error msg should go away.

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

Hi my brother MFC 7420 will not recognize the new toner i just added...........i hve done this multiple times before........not sure now why not working.........are the printer gods against me today??


all brother printers and mfc products. if you are using generic tonere or refills, brother products will not recognize the toner cartridge as the refillers do not know how to reset the toner cart. this is priority info. therefor u must use brother oem toner.brother service rep
