Brother mfc 420cn, machine error 46
Your waste ink absorber box has reached its limit. You have to replace the box (which is cheap, get one from your local brother service centre).
After replacing it you have to reset the purge counter and flushing counter.
This is not easy to do and I don't recommend it for anyone who is not technically inclined. You have to remove the front control panel, open the covers on the top cover assembly under the scanner. Unplug all the cables. Disconnect the ground wire (if any), remove the prop, remove the scanner assy by opening 90 degrees and sliding rearward. Put scanner aside. Remove four screws holding top case on, pry out the bosses at the front and remove the top cover.
At the rear you will see the flushing box or waste ink box. Lift it up a little. You should see two tubes attached. Remove the tubes and pull the box out. Dispose of old box. Attach the tubes to the new box and install it where the old one was. Reassemble in reverse order. Don't forget to plug in all the cables under the control panel.
Plug the unit in while holding down the Menu button. Keep holding until all the lights are flashing. Welcome to maintenance mode.
Press 8 and then 0. Press the Black Start key several times until you see Purge or Purge Count on the display. Now press 2, 7, 8, 3 to clear the count. Press Stop. Press 8, 0 again and the Black Start key several times until you see Flush or Flushing count. Again press 2, 7, 8, 3 to reset the flush count. Press Stop. Press 9 and 9 to exit maintenance mode. Job done.
