1. If error message still says replace waste toner box, then you need to check the sight glass again. The flag must be horizontal at the bottom of the glass or it is not completely empty.

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

1. With unit powered On, open the front cover.

2. Press the "Options" key. Display will show "Replace Drum?"

3. Press "Start" key.

4. Press 1,0 .

5. Display will show "Accepted" for approximately 2 seconds. Then display will change to "Cover Open".

6. Close cover and see if Toner Life End error message has gone.

Good Luck and Thank You for using Fixya.

There's a window on each end of the cartridges and light shines thru to show when they're empty, your refill toner may not be the right density. If you put a small piece of electrical tape over the windows on the cartridge, the error will go away, but you have to watch print quality to change or add toner.

To reset the sensor after installing a new toner cartridge follow these steps.
1. With unit powered On, open the front cover.
2. Press the "Options" key. Display will show "Replace Drum?"
3. Press "Start" key.
4. Press 1,0 .
5. Display will show "Accepted" for approximately 2 seconds. Then display will change to "Cover Open".
6. Close cover and see if Toner Life End error message has gone.
Please note that this must be done with a new cartridge so the unit will see that there is toner in the cartridge.

the solution is to reprogram the eproms on the cartridges, easily done.

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.

I spoke with Brother and one of the options was to open the cover, push options, push start, and then 1, then 1 again. If accept comes up, select. Then close cover and try again.

There is no reset code the likely thing is that you have a faulty toner cartridge. Put another new one in and check the machine then.

Before you try the above shake the toner cartridge and tap it some more as it may also be the toner inside have become solid and needs breaking up.


Hope one of the above works for you
Thanks J
