removing print head on Canon i550x printer

Nicola,

I looked back through your posts, and you never mentioned what carts/inks you are using. If you are using 3rd party prefilled or refilled carts, there is a possibility that a different black ink will help. Some inks aren't as good at generating the small bubbles required to push the ink drops out of the nozzles as they should be.

It is also possible that the cart isn't feeding ink to the cart discharge properly. Remove the black cart, hold it over a wadded up paper towel and gently blow into the vent port on the top front of the cart. Ink drops should be pushed out of the exit with less than 10% of the pressure required to blow up a balloon. Again, the fix would be a new cart.

Hello
I'm using Canon ink tank cartridges, I haven't used any 3rd party inks or refilled them. Unfortunately I've had this problem since the beginning of the year now and have tried buying new black ink on couple of occasions. I really wish it was this though! I've tried using the compressed air on the mesh surface of the print head. I just don't understand how I get these stripes all the time instead of solid black. Is there only one print head? It's almost like half of the output device for this colour doesn't work... Any other help on what to do if it's the nozzle that is the problem? It that the metal part on the other side of the print head where the ink comes out? When I use the compressed air lots of ink comes out.
