Welcome to HP support community.

Did you make a copy and check if that prints in black?

Meanwhile:

Print a Print Quality Diagnostic Page

1. Load plain white paper in the input tray.

2. From the printer control panel, open the Setup  menu.

3. Open the Reports or Tools menu.

4. Touch Print Quality Report.

   A Print Quality Diagnostic Page prints.

   

If that does not print in black, follow the below steps:

Clean the printhead

1. From the printer control panel, open the Setup  menu.

2. Open the Printer Maintenance menu.

3. If necessary, open the Tools menu, and then touch Clean Printhead.

   A test page prints.

   

4. Examine the test page.

   • If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. If necessary, repeat these steps for the third cleaning cycle.

I have tried all the tests and cleaning procedures listed on the HP solutions page.  Black still does not print, although all the colors print correctly.  I have inserted a new HP black cartridge.  Do you have any further suggestions?
