Canon i850 won't print yellow!

[yhelothar]

Actually it DOES print yellow, from the nozzle check. But when I print a picture from photoshop or windows printing wizard, it won't print yellow! The magenta and the cyan works perfectly though, which I have refilled those too. I did deep cleaning. Any idea what is going on?

Perhaps try reinstalling the printer software. If it prints during the nozzle check, then it should be physically fine.

I had a similar problem with my Canon S750 which may or may not compare to your problem.
It had been sitting unused for a very long time by the owner. On printing a test page I only saw colors, no black. When doing a nozzle check in the maintanance software I saw black, but according to Canon's tech support it was a composite black from the 3 primaries.
To keep this short, the ink jet for the black ink was plugged. They sent me a new ink jet module and all was well.

You could have either an air lock in your yellow cart or a clogged yellow printhead...

sometimes there is a problem printing colours because the picture format. If you have it in CMYK or RGB if you have it RGB it wont print right

Just tried that, same thing 🙁

What's airlock? How does the yellow print on the nozzle check if it's clogged?

I've tried both, no luck 🙁

If you've got yellow in the nozzle check test, then the cart is fine. Does it show the yellow tank to be full in the driver tabs? In any case, the problem has to either be in the printer driver or the software you are using at the time. Worse to worse, reinstall the drivers and/or software.
. In your printer settings or image editing software settings, check the yellow slider, make sure it's not all the way down. The nozzle test (in fact all the maintnance tests) bypasses any software settings.

I reinstalled printer drivers, also tried two different software to print, same results.

I suppose if you tried using that printer on a different computer you could determine the general source of the problem.
