Brother MFC-420CN still unable to clean even after purge reset

SOURCE: Brother mfc 420cn, machine error

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.

most likely your flush box is full of ink, the pads will need to be replaced by a service center.

n the mean time you can RESET this purge count back to zero using the MAINTENANCE 80 menu, to continue using the printer for a while until you get the new pads. But it on a tray as if they are full they may start to leak onto your desk....

1 . Press (MENU) (MONO START) then (^) OR <the up arrow> four times, the Photo Capture and Red Exclamation Lights will then flash.

2. Press (^) eight times until you see <8> then press (SET)
3. Press (^) twice until you see <0> then press (SET)

You will now be in MAINTENANCE 80.

4. Press the (MONO START) its a toggle until you see PURGE:6451 ( I guess this means you have cleaned the heads over 6,450 times their threshold level.) you will need to enter the code <2783> to RESET it.

5. Press (^) twice until you see < 2 > then press (SET)
5. Press (^) eight times until you see < 7 > then press (SET)
5. Press (^) nine times until you see < 8 > then press (SET)
5. Press (^) four times until you see < 3 > then press (SET)

The Printer will beep then reset counter will be at ZERO <0000000>

Its the PURGE that will increment by a variable amount each time you clean the print heads the amount will be between 100 and 130. When this count gets to about 64,000 the error 46 will occur. That's about 510 times you can clean the heads before the pads need cleaning.

Almost forget to EXIT the Maintenance mode enter 9 twice by using the up arrow & set key's to exit from maintenance mode in the same way as entering the 2783 code, or power down the printer.

you need to dismantle the printer by opening the scanner lid, pinging the blue arm out of the white retainer with a screw driver, flip the scanner lid right over onto the desk on the LH side of the printer - it will come off its hinges for this. lay it lid down on the LH side of the printer - be careful not to snap the power and data cable connecting with the base. Next you have to remove the 4 retainer screws in order to remove the plastic cover over the rest of the base. The pad and ink box are at the rear on the right hand side.
