Smart Tank 519 doesn't print black

[JohnB1958]

My black ink stopped working.  At first it was having intermitent ink feed and finally it stopped working.  I have Print Doctor and ran all the programs, includin cleaning the heads.  I can see that the feed ribbon which transports the ink via thin veins has a dry black 'vein' leading to the print heads.  Ink is full and printer is 2 months old.  Re installed drivers as well.

Hi @JohnB1958,

 I'd like to help!

To better assist you - 

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or device? 

While you respond to that, let's print a Print Quality Diagnostic page -

• On the printer control panel, press the Resume and Color Copy buttons at the same time.

A Print Quality Diagnostic Page prints.

Post the Print Quality Diagnostic page here so we can help you further. 

You may also refer to this document with steps to fix the " Print Quality Issues" issue applicable for your printer -  Print Quality Issues

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

Hope this helps! Keep me posted.
