    Got 'No Cartridge' error. Turns out I hadn't replaced the correct cartridge.

    Go to the brother site. The solution was there and it worked.

    My magenta cart remains unidentified even though I have just put a new cart in. It keeps saying that the magenta is near empty, replace it. I have done that right now - replaced it with a brand new cartridge. When I test print, it only prints black, cyan and yellow but not magenta... frustrating!!!!!

Unplug printer from power. Wait a minute. Take all carts out. Plug machine to power. mfc demands carts. Reinsert carts (have a look if they all filled with ink!!). If asked press 2 (No change) despite you use a new cart press 1 Yes cart changed.

Should work!

This worked on my MFC-640CW with the error "No cartridge, Install Cyan."

The problem occurred after moving the printer. All ink cartridges were untouched.

The problem followed the Cyan cartridge if it was in the Yellow or Magenta slot.

  1. Pressed On/Off
  2. Immediately unplugged printer.
  3. Pressed On/Off while unplugged.
  4. Plugged in printer.
  5. Pressed On/Off. (Printer said, "Shutting down." Allowed the cycle to complete.)
  6. Pressed On/Off to start printer.
Printer now said, "Cleaning," and job in PC printed automatically. The Brother Control Center 2 now says there is a tiny bit of cyan in the ink cartridge.

    the solution is to fool the sensor by putting black tape ( or use a piece of the label on the cartridge) and cover the part of the cartridge: see the image in the link)



Nothing seems to work, suggest don't buy brother printers, all have this problem

Well, I have the same problem and I called to get advise and ran all the test and what the problem was is I did not buy new ink insted I refilled them with an ink refill kit and well the ink is not the same and can clog it up and you are going to have to send it off to get it fixed more than likely a new printer head or maybe it just needs cleaned that is what the guy told me on the phone that fixes them for a living and is certified through brother to fix their printers so if you bought a refill kit or did not use the brother ink then that is the problem

Is there a way to get Brother MFC-240C to only use black ink cartridge?

Theres a simple trick to cheat the machine.
you will definitly destroy the printhead when doing so for a longer periode!

You have to put some black adhesive tape around the middle part where you can see this black palstic flag inside the cart. This flag signals the printer that the cart is insert and later on when the ink is down to give the waring: near empty.

I do give you the advice to do another but saver cheating:

You can refill the cart with a mixture of 8 ml destill water and 3ml 85%-Glycerol (e. g. Glycerin alc. which can be bought at a drugstore for a few cents). Shake the mixture well (within the syringe) before refilling the cart.
See pics here how to do so (LC1000): - Refill
(brother has changed the construction of the carts! If you can see a plastic quad in the middle of the cart, you have to drill the hole just behind the air valve (white plastic looking out of the cart)

Ink problems....

Take all carts out of the machine. Have a look into the cart holder. Is there ink swapping beneath the white plastic? (You might shake the machine ;-)

If yes, the cart holder leaks and needs replacement.

If not (your lucky!) it could be that the automatic cleaning procedure which starts when a cart is changed has soaked the carts empty.

Do set machine with date and time and NEVER unplug NOR use a power switch which breaks the power supply.

Do use constant power and switch off machine by pressing stand-by-fax-button!

Everytime when machine comes to (new) power contact it runs an extensive ink cleaning procedure. thats why your carts are always near empty....
The stand-by will prevent this and machine does some cleaning procedures which consumes only a few drops(!) of ink!

The display asks you if you have changed the carts. Do answer this question by pressing 1 for YES or 2 for NO.
This will reset the built-in inkcountermanagement to the correct settings

Brother MFC-420CN All-In-One

unplug maqchine from power. take all carts out. wait 5 minutes. connect machine to power. insert carts as demanded. give the right answer if machine asks if the carts are changed. machine will do some cleaning.

do you use generic ink? in that case you might have clogged the printhead with wrong ink. The ph cant be cleaned anymore.

nevertheless try this (carts should be nearly full!):
press menue then start mono (blue copy) then fourtimes arrow up. machine will be in maintenance mode. press 7 then 6 then 4. Machine will display init_all. press start mono. machine will refill tubes and
ph with fresh ink and do some cleaning. after that press 7 then 6 then 3 and start mono. machine will do a powerpurge.
press zero then 9 to do a quality test print. If it cant do the job leave maintenance by pressing 9 then 9. do the test print manually by pressing ink etc.

If you still do not see any colors the ph is clogged and cant be fixed anymore. It has to be replaced.

Brother MFC 4820 c won't see new ink cartridge

No, are you sure that another ink is not empty, power off remove all carts turn on, insert carts machine should ask if new cart were installed answer yes to any that are new, use brother carts.


Inks are deemed empty even when a little is left it must be this way to avoid air getting in lines.

Brother MFC-640CW Replaced Black catridge becomes empty

Compatible carts do make a lot of trouble. One point is the draining! The ink has flown into the cart assy and beyond that to the bottom of the printer. As long as you can print without problems you dont have to do anything. If the test pages wont show the correct color you have to open the printer and to clean the assy and the bottom.

Do use original ink carts though these wont drain and give correct info to printer. You can very simple refill them with dye ink. Dye ink only!!!

Near empty yellow

Do print until the message EMPTY (Printer stopps printing). DO NOT refill or change cart when message is shown: NEAR EMPTY! You fool the printers logic. Machine counts down the rest of the ink in the cart. When you refill at that moment the counter is disoriented! To clear the counter: Unplug powercord. Take carts out. Wait 3 min. Plug in power. Machine demands carts. Do use carts at full level (refill before you put them in). Works normal afterwards.
