When "Ink Absorber Full" or "Ink Absorber Near Full" appears on your printer screen, it's time to replace the Flushing Box (and/or the Ink Absorber Box).
Given the difficulty of this repair, it might be advisable to replace the Ink Absorber Box first, see if that solves the problem, and then replace the Flushing Box if that doesn't work, even though it will save time to do both at once.

To reassemble your device, follow these instructions in reverse order. If you haven’t already, it’s recommended that you also replace the ink absorber box during reassembly.
Screw torques from the service manual have been included if you happen to have a torque screwdriver, but don’t worry about them if you don’t.
After reassembly, follow the following steps to reset the purge count in order to clear the “Ink Absorber Full” error:
- Plug the printer in and turn it on.
- Press the Home button (the house icon) on the front of the printer until the Maintenance Mode screen appears (approximately five seconds).
- Hold down the blank button at the bottom of the screen until a number keypad appears on the screen (approximately two seconds).
- Press *, 2, 8, 6 and 4 (you can use the onscreen keypad or the printer’s built-in keypad for this). The printer will beep and MAINTENANCE will appear on the screen.
- Press 8 and 0.
- Press the down arrow repeatedly until PURGE: (or FLUSHING:) appears on the screen.
- Press 2, 7, 8 and 3. The printer will beep and MAINTENANCE will again appear on the screen.
- Press 9 twice to exit maintenance mode and reboot the printer. You can also use this to start over if you make an error.

Hi there.
Great guide - although some pics of re-assembly and re-routing of the cables that were de-routed would have been very helpful. I am a complete novice and I followed this guide to the letter. I was successful in installing both boxes and re-assembling the printer so that on my initial power up it showed a fully usable touchscreen. However I then had a problem where it would not detect (any of) the ink cartridges.
I thought it might have been a loose connection and went as far back as re-seating the connections on the main PCB frame. After that the touchscreen display just remained blank.
I can’t think what I could have screwed up in re-seating things. One step forward - two steps back !
If anyone reads this and has some idea I would appreciate any assistance.
Cheers

When fixing the tube support plate be careful to have the blck cables of the switchback sensor harness pulled out as far as possible, it will be stuck under the plate and too short to plug it in again.

bonjour.
Excellent guide -j’ai le MFC-J6520dw il est tout a fait compatible.mais j’ai un autre probleme “please dl rom” j’ai meme mis a jour le firmware.bonne journée et merci

Désolé, je ne peux pas vous aider avec le problème "dl rom". Peut-être demander dans les forums? (Ceci provient de Google Translate; j'espère que cela a du sens.)

Great guide.
Take care when replacing the 'carriage frame assembly' as I had continual paper jams on initial reassembly. I completed another tear down to get at this part and re-seat it properly (just more jiggling until satisfied that it was well seated). All good then. Also, I don't believe I had to carry out the second part of point no. 11.
Valuable guideline.
I have replaced the ink absorber and the „Spülkammer“. After the re-assembling and the initial power-on, I get the error message „paper cartridge noot detected. Replaced the paper cartridge in the device, again.“ I dis-assembled step-by-step the printer again to double-check all the cables and their connectors. Without success.
Any hints, where I can find the root cause?
Within the chapters of this guideline I don‘t find the right advice, unfortunately.
Linked in the main page for this device is the service manual. It may help.

Worked great for my MFC-J$%10DW - thank you. My after-thoughts:
1. I agree with the comment above: "When fixing the tube support plate be careful to have the blck cables of the switchback sensor harness pulled out as far as possible, it will be stuck under the plate and too short to plug it in again."
2. I also agree that the second part of step 11 (cable derouting) is not required.
3. When re-assembling and re-routing the cables, I studied the author's photos to supplement my memory. Afterwards I discovered that the service manual (linked from MFC-J4410DW ) contains detailed diagrams of how to route the cables.
(Continued as I am about to run out of character count.)
Please feel free to edit the Guide.

4. "Conclusion" step 4: My printer was in "ink absorber full" error mode before I replaced the ink absorber and flushing box, and instead of "MAINTENANCE" it showed "Machine Error 46". I needed a bit of extra help from the service manual at this point. After entering "80", the printer is in a mode where it displays individual items from the "Equipment log" at the top of the screen. To see the "down arrow" on the screen you have to press ">>" button twice. The down arrow then appears as the top left button on the display. You then press this about 35 or so times. Each time the display shows a new item from the log. When the display shows PURGE:[number] you then enter 2783 to reset that counter to zero. You are now at the beginning of conclusion step 5, so you enter 80 again, press the down arrow a few more times than before until the display shows FLSBK:[number] and then enter 2783 to reset the black flush count. This seemed to reset the colour flush count too.
Hallo,
Danke für die Super Anleitung.
Oben in der Beschreibung steht, dass es nicht unbedingt notwendig sein muss, die Spülkammer auch auszutauschen.
Woher weiß ich denn, ob die Spülkammer getauscht werden muss? Oder ist es empfehlenswert immer beides zu tauschen?
Die Fehlermeldung bezieht sich ja eigentlich auf den Absorber.
Und: die Links zu den Ersatzteilen funktionieren zumindest bei mir nicht.
The only help I can offer is that the service manual is on the main page for this product.

Klasse Anleitung.
Wird es in absehbarer Zeit auch Ersatzteile und eine Anleitung für den Brother MFC-J4340 geben?
Wann wird eigentlich Tinte in die Spülkammer und wann in die Absorberbox geleitet?
The manual for this model is on the product page.
