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:Open the front panel.
Remove the toner and the drum
Remove the toner FROM the drum
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.
Put everything back in.
Turn on your printer if it's not already.Now, the low toner light should be gone and the green light should be on.
Now, you can really empty your cartridge.
