the print head is clogged or defective.
you can do the automatic print cleaning a few more times. It basically just forces ink through the print head to try to clear it. sometimes it takes a few tries.
you can also try the alignment function
after that you need to replace or manually clean the print head and that is not easy on that printer as it is not designed for print head replacement
there is a 20 minute youtube video on how to do it on this link
