Question about Brother MFC 420CN All-In-One InkJet Printer
Still getting message "no cartridge" open scanner cover, then reinstall ink cartridge, i've done this over and over but still get the same message
I have the same problem with the ink cartrige. it says the yellow is near empty. I replaced it twice with a new on and still says near empty. I have the 420cn. prior to this had the 420 it did the same problem with the black and I got so fed up just threw it out. It is definitely a sensor problem with the brother's all in one printers.
I do not know what was meant to put paper over the window. where is it located. Over all I like the brother printers but I will not buy a 3rd one because of the same problem.

This problem seems to be the same for all this family of printers. The solution is that each cartridge has optical window on it where the sensors sees the ink level. what u do is put a folded piece of paper over the window so the sensors thinks it is a full cartridge. this will reset the ink level and u should have no problems.

Unplug the printer from the wall, wait a few minutes, and plug it back in. Hard boot.

Putting a piece of tape over each cartridge window, solved the problem for me. I used some very thin white tape. Make sure you shut the printer down completely and restart it after doing this. I got the warning that all the ink levels were low and would need to be replaced, but no longer prevents you from printing. I did a test page all is well.

I have the exact same printe and the exact same problem. I found the compatible cartridges were the problem.

This might be for several reason:
1. You are useing generic ink carts, which do make a lot of trouble because of bad ink and/or diffrent construction that leads to this problem.
-> Use another cart. Bestway: original brother ink cart.
2. You have forced a cart into position and squeezed the led-control board out of its holder. (The led control board has to be plugged in again).
3. The cart isnt secured by the white stand. Make sure that the nose of the stand is clicked into position above the top of the cart.
4. Did you answer the question of the machine? You might have to answer the chaning of the cart.
In case none of the solution given can help, do the following:
take ALL carts out of machine. Unplu machine from power outlet.
Replug to power and watch the display. reinsert carts as demanded by machine and answer question on lcd.
