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 ;-)

Printing in yellow tones, all ink cartridges are full and grid pattern ok and nozzles cleaned


Possibly the print head is getting plugged or the color map settings are changed. Try removing the printer and reinstalling the drivers as well as clicking the "default" settings button after. If this does not fix it, possibly the head itself is ok on a test pattern with low ink but on printing is not delivering full ink in all colors, only yellow, indicating the head is plugging. Possibly cleaning with alcohol would help, place a drop on each place the cartridge inserts on the ink tubes and also clean the head surface where the ink comes out with a Q-tip and alcohol and then do a regular head clean.

Red and yellow inks will not come through


Remove the print head from the cradle and examine the contacts for any wear or gunk, clean contacts if necesary and put the head in a bowl and pour boiling water in the top where the ink tanks normaly go, repeat this process until no more ink flows out (will take a while) being careful not to burn yourself, dry the head out with a soft lint free cloth and re-install and try deep cleaning again, If still not working replace the head with a new one. They retail for around $60.00, it may also at this point be worth considering another printer, they are quite cheap and consider the fact that you would be getting a warranty.

HP 812C will not print yellow but everything else is A-OK Repeated cleanings have NO effect. Cleaned contacts on printer where it connects to cartridge, no effect. HP 23 cartridge only has about 10 pages...


HTML clipboardHi,
It you haven´t used your printer for a while It sounds like the yellow has clogged up in the print head.
Although you have ink you need to print something regularly about every 10 days to keep the tiny jets open
otherwise it´s like trying to pass a camel through the eye of a needle.

So the inks may have clogged up?

The empty weights are 65g C6615A [No. 15] black and
90g C1823A color ink cartridge
anything over that... 1g = 1ml of unused ink.

So if you still have ink you can easily unclog it with a HTML clipboard Magic Inkjet Flush Kit (find it on Ebay)

Or you can read more here:

Good Luck!

C84 Wont print red


The printer colour cartridges are magenta, cyan and yellow. The printer prints "red" by mixing magenta and yellow ink. So, if you only get yellow when you print red, it means you aren't getting any magenta ink on the paper.

Have you tried a cleaning cycle? If not, try one (right click the little printer icon in the bottom right corner of the screen and select head clean). Now run a nozzle check (right click the little printer icon in the bottom right corner of the screen and select nozzle check). Is there any sign of magenta ink on the paper. Try up to three cleaning cycles. If ink is now flowing, but not yet perfectly, don't carry out any more cleaning cycles. Just leave the printer for 24 hours (to allow any air in the print head to disperse). Then repeat the cleaning cycle/wait process. It may take a while to restore a perfect nozzle check print.

If you have already done lots of head cleans with no result, are you sure you have a good magenta ink cartridge? To eliminate the possibility of a faulty cartridge, buy a new set of compatibles on E-Bay - they're very cheap. You can always re-use the old one later if it turns out it is OK.

If none of the above works, then you may have blocked magenta print head nozzles. You can try soaking the print heads for 24 hours (or more), as follows. Turn the printer on, and as soon as the print head moves out of its parking position, pull the power cord out of the back, or turn the printer off at the mains. You may now carefully move the print head by hand over to the left hand side out of the way. Look inside the print head parking area on the right and you will see a small rubber cup that comes up to cover the print nozzles when the head is parked (to stop it drying out). Use a syringe or dropper to fill this cup with head cleaning fluid or distilled water. DO NOT USE TAP WATER. Carefully push the print head by hand fully into its parking position so that the cup full of fluid
comes up over the print head. Do not turn the printer on at any stage in this process. Leave this for at least 24 hours, then turn the printer on and try a head clean/nozzle check again. If you get any magenta ink on the nozzle check, then there is hope! Repeat the process until you get a full magenta nozzle check. If nothing, repeat the process once more.

If still nothing, post a new comment detailing what you have done and the results.

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?

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!

Your black, yellow, and blue ink cartridges are empty, go to your local ink cartridge store or Staples, or Bestbuy. The only ink left in the printer is the red.
