There is a gear on the left hand side of the toner to reset the toner count this can cheated be rewinding it. Yes the design is to stop the refillers or at least slow them down a bit. If this fails purchase a new genuine toner but I have seen problems with the switch that resets the toner (Either the spring on the switch has popped off or the main board has failed).

where and how to find the reset actuator?

SOURCE: 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.

Try this:

Open the cover, leaving everything inside. Press Options, then *00 to reset the fax.

If that doesn't work:

Open the front cover and remove the cartridge and drum. Turn off the fax. On the right-hand side of the cartridge, there is a round hole that is covered with a clear plastic or glass. Cover that hole up with tape, put the cartridge back in the drum, and put them back into the fax, and turn it back on.
