Have you checked ink levels in the black cartridge to ensure there is ink available?

 

Have you tried removing the cartridge and re-installing to ensure full connectivity between printer and cartridge?

 

Also, try cleaning the electrical contacts of the cartridge and in the printhead of the printer to ensure no ink is blocking the electrical contacts.

 

There is also a document with further steps to help troubleshoot a print quality issue.  The document can be found here.  Hope this helps.
