Question about Brother MFC-640CW All-In-One InkJet Printer
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.
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 ;-)

Tips for a great answer:
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.

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!
