Toner life end warning light. replaced with new toner/drum still error

why toner life end message keep on showing on sp 1200s prints.

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.

Meaning the life of the k drum is near and you need to replaced it soon or later
other message like below need attention

Hi there,

After replacing the drum and toner you may need to reset the drum life of the machine. This is how to reset the drum life:
Open the front cover where the drum and toner are located. Press the clear/back key. Lcd should show Replace Drum? Then press 1 for yes. Lcd should show accepted. Close the front cover the press stop/exit. Lcd now should show the date and time.
Hope this helps. Rate if it works. Thanks

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:

-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.

I hope it helps

Open the door where the toner goes. Press the 'back' button. Press *00. Do not respond to the query about the drum. Close the door. Other models may have to press the 'Options' button located near 'Copy'. This should work.

hold cancel button down with door open, this should rest it
