All of my ink cartridges are full but the yellow won't print.

INK PROBLEM
Inkjet printers need to be used frequently to prevent inkdrying out and blocking 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.

You need to align strongly....... If it doesn't work properly .... remove your catridge and rub its head neatly .. and replace again..... thanks

Hello,
try to do deep head cleaning, few times. If this doesn't helps you need to remove the ink's and print head and bottom of print head ( where are ink nozzles ) few times press on wet cloath.

Then repeat the deep cleaning.

It's possible that the printer contacts are worn or dirty. You can try deep cleaning the print head up to 5 times and let the cartridge seat to see if there is any improvement. Also, try changing it back to your old one to test it and see if it gives you the same result.

First try to replace the yellow toner cartridge. After that, try re-seating the cartridge (take out the cartridge and place it back in carefully making sure it is seated correctly). If this does not resolve the issue, clean the print heads and connections on the cartridge. This can be done by removing the cartridge and swabbing the connections with a Q-tip dipped in rubbing alcohol. Also, while the cartridge is removed, swab the connections to the cartridge that are inside the printer where the cartridge is seated.

there is a cleaning utility "printhead clean" and printhead deep clean" under "maintenance" in the "printer properties". Try that first. If that doesn't help and there is definitely ink in the cartridge(s), you can remove the cartridges and soak the printheads in 5mm of hot water for 1/2 hour or so. DRY WELL then install back in printer and run "printhead deep clean".
Another way is to isolate the colour that doesn't print properly and print few pages in that colour (eg if yellow is not printing right...set out a full page of yellow background and print on high quality setting until yellow starts to print ok). This wastes less ink than the cleaning utility.

good luck with it

If a line doesn't print, the ink is out of the cartridge for that inkjet cartridge color. Replace the cartridge. Deep cleaning can use a lot of ink up at a time.

Ok I understand the printer says its full but are you saying your computer says no ink? or that it prints no yellow ink?

Ok assuming you mean that it prints no yellow ink, the culprit ususally means that the print head needs replacing! Call Canon with your model and you can buy the part for new print heads for your printer

Your print head is likely toast.

The only way to be sure is to test out your purge unit (aka capping assembly).

This assembly provides the suction when you use the cleaning function. One test is simply to install a new oem ink cartridge, do a bunch of cleanings and see that it is actually emptying the ink out of the cartridge (look in the cartridge and see that the ink is being used up).

Since you said you have tried several cartridges, I would hope this means you know 100% for sure that the ink level in the cartridge is going down (you cannot rely on the level indicator in your driver software).

Since your purge unit is working, then your print head is either so clogged that the purge unit isn't strong enough to clean it, or the print head is defective.

Remove the print head and inspect the bottom. Give the bottom surface (and no more) a rinse under very hot running water. Blot the bottom surface on paper towel and see if there is any yellow ink coming off in the paper towel. If you can find a tube that will fit over the yellow ink well in the print head (the part that contacts the ink cartridge) try and force water through the tube and see if a fine mist comes out the bottom of the print head. If yes, then the head is not clogged. If no, leave the print head to soak for several hours. A saucer with a small amount of water in it will do. Just let the bottom surface of the print head contact the water (the cap off of a can of spray paint usually works for this)

Let the print surface soak for a few hours, or even over night. Reinstall the print head and give it a deep clean. If it still does not work, call your local Canon repair shop and check the price of a replacement head.

remove print head assembly. clean off.
