Here's a permanent fix. Basically you cut the wire to the ink sensor. You can no longer see the ink levels, but that didn't matter anyway, as it was incorrect before!
First of all, TURN OFF THE POWER TO YOUR PRINTER. Then lift up the scanner and remove the three screws along the top of the control panel. With a bit of force, snap-up the most inner two

Just replaced ink cartridges on my Brother MFC


Hi there you can refill Brother cartidges, like other printers it will not have it sorry.

This is the only way you can trick it.

There are only a few steps you need to do to reset a Brother printer ink cartridge and once you do it, you will be up and printing in no time. There are actually two things that a Brother printer uses to detect ink and you can manipulate one or the other.
Instructions
Things You'll Need: · Black electrical tape, masking tape or duct tape
1. Step 1
Identify the printer If your printer uses memory, you can tell which printer you have by looking at where the cartridge goes in, if you see two "eyes" and a part of the cartridge goes in between them, follow Step 3. Otherwise, continue with Step 2.
2. Step 2
Clear the memory by taking the cartridge out and unplugging the unit for 30 seconds. Then, plug it back in and put back in the cartridge. You may need to do this five times, as the memory holds the last five cartridges.
3. Step 3
If the Brother printer has "eyes" where the cartridge goes, you will need to block in between them with a piece of tape so that it thinks the cartridge is always full. Simply put a piece of tape on the piece of the cartridge that goes in between the eyes to block the path of the infrared beam

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.

MFC-420CN refuses to recognize or use black ink


The print head is clogged.Try powerful cleaning:
Press menu, then start black copy, then four times arrow-up quickly after another.Machine will be in maintenance mode
(all lights will flash).
Press 7-6-4 and OK (or start-black-copy).
When finished press 7-6-3 then start black copy,
printer will do a power purge.
Leave maintenance mode by pressing 9-9.
If this not help better think about new printer, because cost of repairing this one is profitable.

Brother MC420CN- Black ink cartidge 'near empty' message persists


At 1 of the end sides of the cartage you will see a little window, a beam of light hits that window to determine if you need Ink..Place a small piece of Electric tape over that window and.wallah print,fax and copy away. Brother is a ripoff-A cheap printer that auto-cleans(wastes ink) and locks the whole system claiming your out of Ink or low>>>But this is sure to work! ;)

Not recognizing ink cartridge


On the clear side of the cartridge, put a piece of electrical tape to cover the center plastic bar that sticks out. For some reason these printers have a big problem with sensing ink levels. The tape lets the sensor think the cartridge float inside is up, meaning a full cartridge. The sensors seem to have difficulty reading where the black float is inside the cartridge.

Printer Head needs removal to clean dried ink


Not a cleanable type head, filiment gets burnt, when ink is not around it when printing is done. Ie dodgy ink blocks lines or has air in it and has permanently stuffed the print head, fix on brothers is replace head, cost excessive.,..time for the bin and the newfound wisdom that inks aint just inks.

Ink empy or no inks is read in ink well compartment via a black flag in ink cartridge that must be up and floating as not to obstuct photocell in well area.. check the rectangler bump in rear middle of cartridge. All cartridges must have flags up ie not empty, seeing ink does not indicate a cartridge with ink, a little is always left to prevent air entering system, hence machine calling out no innk cartridge to prevent damage...

you may be able to reset the ink cartridge detector, in the printer software, so that it detects the new ink cartridge.

the brother printer is not a good brand i also have a brother mfc 3220cn and it gives the same problem, what you have to is unplug the machine and let it stand for about 2 days take out the cartridges and clean the printing with air replace back them and plug in.that should remedy your problem.i urge on you never to buy brother printers.if you buy them get a bottle of phensic along with it.good luck my brother.
