@Geoff81, Welcome to the HP Support Community!

• Have you tried making a Black photocopy on the printer and check if that works?
• Have you tried using an alternate black ink cartridge and check?

Check the estimated ink levels

1. On the printer control panel, press the Home button  to open the Home screen.

2. Press the Down Arrow  to select Ink Levels, and then press OK. The control panel displays the estimated ink levels.
3. 

4. Color ink level indicator

5. Black ink level indicator

6. Replace any low or empty ink cartridges

Clean the ink cartridges

1. Load letter or A4, unused, plain white paper into the paper tray.

2. On the printer control panel, press the Down Arrow  to select Tools, and then press OK.

3. Press the Down Arrow  to select Clean Printhead, and then press OK. The printer cleans the printhead, and then prints a printhead test page.

If the issue persists, perform step 12 and 8 from this document.

Let me know how this goes.

Hi. Kumaro307. Thanks for response Will not print black copy but will print ok in single cartridge mode. Have replaced both cartridges and they show as full. The printhead clean has been done several times, The printing of  IMPORTANT and  2  arrows in red  , also a triangle with an exclamation  mark at the bottom of the alignment  test sheet seems significant but I do not know  what it means. Have tried all your suggestions but still will not print a black copy although the test sheets are piling up on my desk.  Kind regards, Geoff81

That's Unfortunate. If the printer is not able to make a Black copy, it could either be an issue with the ink cartridge or the printhead of the printer.

If there is no black on the alignment page, the alignment won't be successful.

Since you have already replaced the black ink cartridge and the issue persists, please contact our HP Support team for Service Options as it could be a possible hardware issue:

1) Click on this link - https://support.hp.com/us-en/contact-hp?openCLC=true

2) Select your product type below.

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Select the appropriate option based on your preference.

6) Fill the web-form and proceed further.

Keep me posted for any other assistance.
