HP ink tank 415 wireless missing yellow color

[HasseneSoua]

Hello, this is straight forward enough, i  was working and printing some documents and everything was normal until suddenly all the pages i print have the yellow color missing, the ink level in the tank on the yellow color is above half so it's fine and I'm using still the original ink that came with my printer.

I tried the clean printhead function a hundred time and nothing helped, the result page comes with yellow missing while everything is okay, i tried cleaning for ink smears and everything too and also that didn't help at all. 

One last thing, when i opened the printer front to take a look at the printheads i i noticed that the yellow color isn't reaching the end of the tube like the other colors, is there any fix for that? I'm attaching the pictures so you can see
