Question about Brother MFC 240C All-In-One InkJet Printer

1 Answer

When a jet on the Brother MFC-240c print head clogs, how do you access the print head to soak it? And how do you remove the print head to clean up the ink purge area. (This printer cleans itself on every start and every so many hours. This is intentional and is also a design flaw because after a couple years, it results in the highly enclosed print head jets sitting in a pool of drying ink and clogging. And there is NO easy way to get to this print head that I have been able to discover. So....that's my big question. How do I get to the print head. It is independent of the ink cartridges which site in a stationary storage box on the right front side of the printer. The print head itself is above the ink cartridges. I have a clogged Magenta jet. I can see, by following the tubes that ink is getting as far as the print head. Also, does the MFC-240c have a purge tube for each jet? Is there a way to access that, if so, and make sure it is properly connected? I know on some Epsons, the purge tube can come loose and cause the type of problem I am experiencing with the Brother. Thanks, ken

The short answer to "how to remove print head" is there is no easy way. I don't have the service manual for your machine, but I own a 540CN which is similar and, because I have had similar problems to you, I have invested in the service manual for this machine. To actually remove the head requires a great deal of dismantling, including disconnecting the head position sensing belt which then has to be re-calibrated on re-fitting. The method I used to clear the clogged heads (mine refused to print anything in black) was to force a alcohol based cleaner through the ink supply tube using a small syringe and some windscreen washer plastic tubing. In order to catch the fluid (and flushed ink) I folded a paper towel until I could draw it under the print head. This had to be changed several times as I had to use a lot of cleaner until it flowed out of the head clear. Please note that even after I managed to get the black printing again, and even though for general printing the black printing is fine, if you do a print quality test the block of bars for black is nowhere near as good as it is for the colours. I personally can live with this given the cost Brother will charge you to repair a machine - normally more than a new one !. Hope this helps.

Clogged print head

Take print head out, clean with alcohol wipe or swab, re install. Have had to do it more than once if ink has dried a lot. The only other option is to replace head.

Printer prints blank pages

The print head is a part of the printer itself and unlike other printers, you cannot remove it or soak it without ruining your printer. So just try the print head cleaning option and perhaps replace cartridges, especially if you are using a third party or refilled cartridge which can clog even if it is full.

Printer has new ink but does not print even though it sound like it is printing.

what kind of printer? Laser or Ink Jet? If it is ink jet, your print heads might be clogged and need severe cleaning or replacement. If you have the manual it should tell you where exactly your print heads are located. If not, search your printers manual online. If you CAN access your printheads, clean the print heads gently with a cotton swap using rubbing alcohol. do not over wet the cotton swab or print heads as too much alcohol could damage the print heads. If the print heads are very hard to get to and the print needs to be disassembled to access them, it is cheaper and worth it to get a new printer otherwise you could damage something else inside the printer.

If the printer is a Laser machine and you inserted a new cartridge and it is not printing, your Drum unit could be expired or your heat rollers. Drum units are sold online from $50 - $300 depending on the model of the machine. Heat rollers are not worth installing unless you know what you are doing.

Red and Yellow not Printing at all.

Did you use third party carts?

If yes, buy original brother ink carts and do the cleaning cycle again. If you are lucky the printhead isnt clogged due to the third party ink which has not the additives and glycerin needed for the printhead to run without probs.


In case the head is clogged there is nothing more what you can do. Sorry!  A replacement might costs more than a new mfc 440cn!
