About the printer and ink

[091]

 It can't print things with black ink. So I changed the ink but as the image I've attached, you can't see the black ink  in the ink test sheet.

Actually, if you look closer test sheet that is not black ink, it's more grey-brown. That colour comes mixing yellow cyan and magenta. It's definitely not black.

Your black ink part of the printhead has started to fail or has already failed.  Leave printer overnight, and try printing the same sheet next day, start one cleaning cycle, if it gets better leave it for some time maybe your black will start to print again.
