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.

SOURCE: machine error 46

Here is the answer to the Machine Error 46 (have just fixed my own MFC210C):


Machine Error 46 – Purged Ink Box Full MFC620CN/420CN/410CN/210C and FAX2440C

The machine counts all purge (cleaning) operations in order to prevent the internal ink absorber box from overflowing with purged ink. An “initial purge”, for example, advances the purge counter by 187 + 420 = 607. When the purge counter approaches 6400, an internal "Machine Error 46" is generated. Further purge operations are prohibited, and therefore the printer becomes unuseable.

When an internal Machine Error 46 is generated, the user will see an “Unable to Clean” external message and will be unable to use the printer. The “Unable to Clean” external message can relate to many different internal error codes however.

The user can establish the internal Machine Error Code as follows: pull the mains cable out of the machine (power off), hold down the Menu/Set key, re-insert the mains cable into the machine (power on). The internal Machine Error Code will be displayed.

If there is a Machine Error 46, it is necessary to dismantle the printer, replace the ink absorber box (or possibly break the ink absorber box open and clean its absorbent sponges under a tap), re-assemble the printer and reset the purge counter to zero.


Resetting purge counter MFC620CN/420CN/410CN/210C and FAX2440C

1) Enter machine maintenance mode (on MFC210C all four photo/copy/fax/scan lights flash in maintenance mode). Care is needed in maintenance mode, otherwise critical settings may be inadvertently corrupted.

FAX models with numerical keypads: Press the Menu/Set, *, 2, 8, 6 and 4 keys within two seconds. (if you fail to complete the correct key sequence within two seconds, press the Stop key to try again).

Other (non-FAX) models: Press the Menu/Set and Black Start keys. Next press the “up arrow” key four times to enter the maintenance mode).

2) Press the 8 then 0 keys in the initial stage of the maintenance mode to call up the machine's log information list (function code 80).

3) Press the Black Start key several times to scroll through the log information list to reach the purge counter. The purge counter is the 25th item in the list.

4) Press the 2, 7, 8, and 3 keys in this order to reset the purge count to zero.

5) Press the Stop/Exit key to return to the initial stage of the maintenance mode.

6) Press the 9 key twice to return to the standby state.

Carry on printing !!

thanks.

SOURCE: Brother MFC 420cn "Cannot Init"

This is the Head Error 41

Error 41 means there is a major problem with the printhead, usually
requires a print head replacement.

My advice is to take it to a
Brother service centre while if it is under warranty.

If it's out of warranty they are usually a throw away job, the heads cost as much as the printer.

Sorry I know what it feels like, just have a go and see what you can do, clean the heads and so on.

All the Best and good luck: Pineworks

SOURCE: Brother MFC-465CN printer. Need a fix for error 46.

The problem is due to the fact that Brother machines excessively self-clean. Each time they self-clean a small amount of ink is dumped in to a holding tank/sponge. When a predefined number of self-clean operations have been performed, the machine refuses to print and gives the error message you have stated. Brother state that the tank/sponge must be replaced before the counter is reset, again by a Brother agent.

However, there is a way of reseting the self-clean counter yourself - if you Google your model number and the error code somewhere in the results you'll find how to do it. The only risk of doing this without changing the tank/sponge is that it will eventually overflow and leak out the bottom, but I did my Brother all in one some time ago and have had no problems yet.

I have a brother mfc-420cn. I am getting a unable to clean messa


Do you mean "unable to clean"?If it this follow this instruction.
Unplug the printer from power cord.Press and hold the "menu" button, then plug the device.You'll see on the LCD screen a "machine error" code.If this code is 40,41 or 4F the print head is defective.If the error is 50 or 51 there is error in Purge unit and printer require service.If the error is 46 the waste ink tank is full.Follow this:Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If numberis over 6000, enter 2 7 8 3.This will reset the purge count value. Then restart the printer, hopefully without the annoying cannot clean message.

Error-46


Machine error 46 ("Unable to Clean") indicates the wasteink "sponge" as full, which disables the machine's ability to clean. To fix this, you could get the needed part from a Brother parts dealer and enter the servicemode to reset the counters. However, the more reasonable thing to do would be to just change to another machine. You could also have the machine sent to service, but that most likely would not be worth the trouble. The error is pretty common on old Brother inkjets, so it'll come back eventually even if you replace the part. Newer machines should not have this problem.
