I have this Canon printer for years now, I replaced the colour cartridges last year with some no name brand. I have not printed anything for a few months. Now I wanted to print something and it only prints black and white. Even the test page is only black and white.

I tried deep cleaning the print head and it doesn't help. I removed the print head manually, but I couldn't see any issue.

Is there any way to clean it manually to remove any clogs or whatever is blocking the colour print jets?
