AF after cleaning cycles??????????????????????????

AF means that the scanner flatcable is not connected to the main pcb (When powering up you should hear a grinding sound from the scanner area). Open the scanner cover as for changing the ink carts. Open the small cover (looks like a " L ") and connect the white flat cable simply by pushing it into the main pcb.

How do I remove and replace the ink absorber pad/tank on my Brother MFC - 820 CW

Have a look at which is specificlly for the MFC-210c - no sure how similar the 820CW is.

It's in German but google does a reasonable translation.
After receiving a "UNABLE TO CLEAN" message, I've just cleaned the pads on my MFC-425CN (washed in cold water) and re-set the purge counter - all working fine now.

Brother Support, including manuals, drivers, downloads, etc. are found at:
Brother MFC-420CN Support

The Brother web site doesn't list an actual MFC-425CN - the MFC-420CN seemed to be the closest fit.

Unable to Init - Machine error 4f

ok please try this

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart, hopefully without the annoying cannot clean message.

All I ask is please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

try this:
take all carts out. Unplug machine from power outlet. wait 5 min. leave scanner top open. rplug to power. wait til machine demands carts. reinsert and secure the carts. close cover. answer questions on display. set date and time again in case its not displayed.

If you still receive message use another cart of a diffrent brand. There are many generic carts with bad construction and bad ink out on market.

Best way: refill original brother carts. drill a 2mm hole on top into the brand name (O of brother). refill C/Y/M with a mix of 2ml 85%-glycerol (glycerin alc.) from drugstore and 10ml of DYE ink (shake well before refilling). For BK use 15ml DYE ink mixed with 1.5 ml gylcerol
shke very well before refill.

Brother MFC-240C init. unable AF error message

Sure. No prob.

Open scanner cover as you would do to check for a paper jammed sheet.

Do open the plastic which runs from middle to the right side (looks like a "Z" turned clockwise). Use a small screw diver for that. beneath you will find th flat cable of the scanner. You have to reconnect the flat cable by simply sticking it into position onto the main circuit board. make sure flat cable is in good position and click the" Z  "onto the channel. Close cover then power up and do what ever you want to do with your mfc ;-)

Brother MFC 425CN will not print black

Have a look at the bk cart. Did you fix it well into position by clipping the support above the cart?
Can you see any difference by ink fuel before and after cleaning cycle? If there is no difference the valve is not open: drill a hole into the top cover and leave it open. Try another cleaning cycle again.

Brother Mfc 420cn says machine error AF

Open the small cover that hides the scanner flat cable. It has to be reconnected to the main pcb.
