Question about Canon PIXMA MP780 All-In-One InkJet Printer
I have this printer for a while and I was very happy with it. A couple of days ago the black ink stopped printing and now I can only print in color. I havent changed anything in the setting or in the printer it seems to happened without no reason. Did it happened to anyone else? is there a solution or do I have to buy a new printer???
I had the same problem I found this solution to be very effective: * Buy alcohol solution (70% or more). You can find it in any drug store. * Remove both cartridges from the printer head. Unplug the printer head from the printer body. Pour the alcohol into paper towel layer. * put the printer head on the top of wet towel with the face of HEAD touching the towel. * clean the head with the towel and get rid of all the built-up ink on the head. * Pour the alcohol into the printer head container (ink-receptacle area is where the ink cartridge normally sits, notice a small hole where the ink flow into the printer). Do not touch any electronic parts and let it dry over night. * Do step 2-5 again if necessary. * Install the cartridge back to the printer and run several head cleaning maintenance, print nozzle check, make sure to repeat this step until no more dead nozzle shown. It worked for me :0)

The solution for this is simple. With respect to the canon iP4200 (and I suspect other printers of the same ilk) all you have to do is remove the printhead and clean the fine mesh screens in the bottom of the printhead with a Q-tip and water. Clean them until the Q-tips come away clean. Also moisten a paper towel with water and gently rub away the ink accumulated on the bottom of the printhead around the electronic contacts. NO need to leave the printhead out to air dry overnight or use isopropyl alcohol. Hope this helps someone out there.

I'm not the patient kind of guy, and I did this with my canon ip4000:
removed the ink tanks, got the print head out (easy!) and held it underneath running hot water (from the tap...). Shook it, let it dry a few minutes on toiletpaper and put it back in. Deep clean on all tanks and now it works perfectly.
Don't know if I should recommend this method though... :)

I found that I could remove the print head (after removing the ink cartridges). Then I used a q-tip and plain water to remove all the ink build up from the print head. It takes a few q-tips to get it all, but the printer now works fine.

If the printer works fine hooked up to an older computer but does not print from a newer computer, the ink tank which doesn't print probably has a date chip which the newer computer is reading that the tank is "out of date" so won't print. You can check this out by changing the current date in the computer to several years earlier...then if it prints, that is your problem. Even brand new tanks can be out of date if they sat in the store too long! I don't know if new tanks for older printers have the date chip or not.

We had the same problem with our MP780 it started with spitting ink all over the place, and then the black just quit. We were set to buy another printer. Took the print head out and it is totally gummed up with ink, Wife is cleaning it now with a pile of Q-tips. I am sure that this will solve the problem. Thanks for the solutions.

Have tried everything :( Soked in water many times, tried alchohol, still not printing black. Are there any cleaning kits out there that might work?

Oh my gosh... I could have saved myself so much grief - and ink - if I'd only looked here for a solution much earlier!
Elsewhere on this site I found advice on how to remove the print heads on my Pixma 780, then I used a handful of Q-Tips as recommended here. I did slightly wet a few of them and blotted excess water on a paper towel to get the more stubborn spots (it worked like magic). Then a couple of deep cleanings and in no time I had my printer working like new.
Thanks to everyone who took the time to help this technologically challenged mom get back on track!

If your print head needs replacing remove it and immerse nozzle area in a small ammount of very hot water (don't wet the electrical contact pad area) leave it to soak for a few minutes, change the water a few times then dab printhead nozzle area down onto kitchen tissue to remove remaining water.

I had a severely stopped up black on my Canon Pixma IP3000 printhead, I hadtried deep cleaning four or five times with no success, so I took an old empty tank and filled it with printhead cleaning solution cleaned it twice and put the original ink tank back in and printed, but still had skips so I repeated cleaning two more times and WALLA success. Now prints as good as new. Bill85

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...
