Reset tn 1000

SOURCE: Brother Printer HL 1240

OK figured out the sequence to resolve this error:

power off unit
unplug power cable for 1 minute
reset the power cable
open front door
press and hold the reset button under the lights
turn the power on
printer should then be reset

I got exactly the same problem and the "reset" didn't do anything. I fixed it by putting a piece of duck tape on magic eye on the cartridge.
Fallow those step to do the same thing as me:

1. Open the front panel.
   
2. Remove the toner and the drum
   
3. Remove the toner FROM the drum
   
4. On each side of the toner, there should be a little glass. Put the piece of duck tape on one of them. I put mine on the right side.
   
5. Put everything back in.
   
6. Turn on your printer if it's not already.
7. Now, the low toner light should be gone and the green light should be on.

There is a reset gear in the cartridge that needs to be "reset" or replaced. I've included a link to a PDF file that goes over the procedure to properly refill and reset the toner cartridge. This is a document that is used by a company that does a complete rebuild, so you probably won't need most of the information, just the part on resetting the reset gear.
