Brother MFC-235C print head removal

Do not try it on yor own unless you are a technician. Too many parts must be removed and counters have to be cleared and programmed. You might try calling brother, they will cover printhead replacement on certain models. Call 1-877-brother.

Take out the magenta cartridge and clean the nozzels and contact and reinsert it. if the issue persists get a new genuine brother magenta cartridge

It looks like the magenta print head nozzels are blocked.
Inkjet printers need to be used frequently to prevent inkdrying out in the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages,then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer thanreplace the print head.

The process to get to the print head will take you approx. 1 hour. Without being trained on it, there is a high failure rate upon completion.

The Scanner assembly needs to be taken off. Harness Cables for the Scanner need to be removed.The Upper Case Assembly needs to be taken off. Printhead casing and printhead tubing calbes need to be removed, printhead mainboard needs to be removed, and then you have access to the printhead.

Thanks

my brother mfc 6490 has stopped printing yellow, i've done number cleans and changed cartridges with no luck. has anyone out there got a fix for this?

i cannot print anything

If you have used generic ink the head is clogged and cant be cleaned anymore.

Last chance is to use original brother ink which has cleaning fluids within the ink. Run the cleaning procedure twice and simply print 10 PAGES afterwards. Wait A DAY AND TRY TO PRINT IN MAG AGAIN:

If there will be no mag. the ph is definitley clogged and needs replacement.

refill ink cart can be problem here, print head may be blocked , try cleaning the head in warm water

Unplug machinepowercord. Open printer and take all carts out. Plug in power. Machine demands carts. Put new one in: Replace with original ink carts!. When asked push 1 (yes New cart). If you have used thirdparty carts, there could be a prob due to construticon or ink quality. In case there is no bk after 3x cleaning cycles anymore, the head is clogged: This happens because the filter in front of the nozzels is clogged by pigmented ink. DO USE ONLY DYE INK for all types of brother inkjet machines!!!

First of all the print head is clogged just because you have tried to print repeatedly while some of the cartridges are empty. This results ink burn in the nozzle and clog. My recipe: Heat some drinking water in the kettle (70-80 C). Put the head in it and shake gently several times until ink is completely clean (10 minutes). Change the water do the same again. Change the water again (70-80 C) this time put a spoon full of apple vinegar (becomes a natural acidic solution very dilute) shake again, clean with cotton stick. I did it and started to love my mp800 again as much as I just bought it, all colours come back and started to print superior photos again...... Do not touch heads' copper poles and cartridges poles because of the static electric they may mulfunction and colours may becaome totally mixed for a short while...
