Printer selectively prints in Black

[kngo]

My Printer AIO  seems to be printing 'selectively' in black and white.  I'm fairly certain that it's the printer is 'able' to print in black but I can't seem to get it to print properly

When I print out a print quality diagnostic page, all of the text is visible including the black outline to the 4 color types but the 'black' box is completely white.

When I try to photocopy a black and white page, a page of paper goes through the printer but comes out completely white.

When I print documents in b&w, the paper comes out completely white but if I print in color I get partial prints.

The thing that confuses me is the black ink on the print quality diagnostic page - but not the black box and everything else.  Does anyone know what I need to do?

@kngo, Welcome to the HP Support Community!

I understand you are not able to print in black. Let us try these steps:

Check the estimated ink levels

From the home screen of the printer control panel, touch the Ink icon . Replace any low or empty ink cartridges.

If black is empty/low, replace it to resolve this issue.

Update the printer firmware

Print a quality report or make a copy in black to check the result.
