TS8152 Prints Brown as Pink

Hello all!

MY TS8152 prints brown as pink... It as working fine so far. 

What I did: Deep cleaning of the heads and then try to print the same brown image again. No luck.

I decided to print it from another computer, no luck.

I replaced all the cartridges for better ones (they are not canon but the printer actually recognized them as genuine - they were at 33 euros instead of 77 on amazon!)

But once again, no luck.

Now I have been looking around and a guy suggests to clean clogs with Q tips. Could that help? How should I proceed? Do I need to get them wet with alcohol first?

Please don't tell me my printer needs to be sent back!!!

Thanks a lot,

Jb.
