MFC640-CW how to remove printer head

Ok, so i used the cheapo ink and ruined my print head so it won't print red or yellow. Is there anyway to remove it and clean out the gunk? I haven't figured out how to get it out of the machine.

Thanx

DO NOT remove the ph!

What you can do is to run the initial set-up for carts:

Place ORIGINAL ink carts into machine!

Press menue then start b/k cpoy then fourtimes arrow up. machine turns to maintenance mode. press 7 then 6 then 4 then start b/k copy. machine initializes the carts and do some very special cleaning. When finished press 7 then 6 then 3 then start bk copy. Machine runs an exrta power cleaning. press 0 (Zero) then 9 to print a test print.

If your lucky the cheap ink hasnt affected the ph nozzels.

Do refill the original carts with a mixture of glycerol (from drugstore) and DYE ink (e.g. jettec) only:
For C/Y/M mix 3ml of 85%-Glycerol with 10ml of DYE ink.
For BK mix 2ml glycerol with 20ml of BK dye ink!

Shake very well and wait a few minutes to let the airbubbles out of the mixture before refilling!

The glycerol prevents the nozzles from drying out ;-)

My epson DX8400 won't print yellow at all, green prints as blue, red prints pink on certain documents i've created. I have printed an email off today which printed all the colours perfectly??


In most cases the printer driver software can have errors while being in use or is shut down. So to reset remove your printer from the PC and uninstall the printer software. Now reinstall the printer software and then connect the Printer to be detected as a new hardware as it will be installed. Now check the printer properties to see the ink levels.
Activate head cleaning before a test is taken . Sometimes it is possible that the head is not reacting to the need of the PC command or can be an issue with ink drying or poor ink cartridge contacts. Sometimes the power supply unit must be checked as a poor SMPS unit can deliver low voltage and cause issues to the printer function. Check all the leads and connections of the mother board , the tags to the ink cartridge. Also check the mechanical settings of the ink cartridge , if jammed or tight remove motor and manually free the drive before it is set back.

Thank you for using Fixya

PIXMA ip3000 printer is printing yellow instead of red


Clean the ink cartridge contacts with a moist tissue or glass/LCD cleaner clothe. Do the same on the printer cartridge holders. Do this gently and carefully avoiding further damages to your printer and it's cartridges.
Declog print heads using denatured alcohol for an hour or two or head cleaning agents available at any ink refilling stations. You can use a suction device included in the refill kit.
Try using another cartridge of the same type by borrowing from a friend, relative or member of the family and see if the problem still occurs.
Try removing the printer driver, restart computer then reinstall driver so that the default settings will be restored. If it still exist, you can google for iptool software and try resetting it's EPROM.
If the problem still exists, you need to go to the nearest service center.

try doing 4 head cleans and then leave the printer powered up over night. Don't print or anything else after the head cleans until the morning then do one more head clean (this soaks the print head in ink overnight and then the final head clean should clear any obstruction. If the printer still refuses to print in colour, you could try replacing the cartridges anyway as they can be faulty. The only problem is thaty sometimes it's cheaper to buy a new priner. (how silly is that!) By the way, are you using compats or epson original ink carts?

I admit it, I used cheapo refill ink! Now the black section of the print head doesn't work...


I'm afraid there is no real sucessful way of cleaning these print heads, tiny micro filters built into the head unit will blocked. I have never unblocked one fully.

Fix is to replace head

These heads are not easy to fit, then once they are you must program in the head id and run a purge with four gen inks, this purge uses like 1/4 of each ink.

Recommennd you replace printer it is cheaper to

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!
