Hi @JStephenH,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!  

We're thrilled to have the opportunity to assist you and provide a solution.

Try the following steps:

Check Ink Levels

• Ensure the black ink tank is filled with genuine HP ink.
• If low, refill the tank properly.

Run Printhead Cleaning

• On the printer’s touchscreen, go to Setup (⚙️) → Maintenance → Clean Printhead.
• Repeat up to 3 times if needed.

Check for Air Bubbles in the Ink Hose

• If the black ink hose is empty:
  • Open the ink access door.
  • Make sure the black ink valve is fully open.
  • Run the ‘Clean Printhead’ function again to prime the ink flow.

Perform a Hard Reset

• Turn off the printer, unplug it for 5 minutes, then turn it back on.
• Try printing a nozzle check or test page.

Check Printhead & Nozzles

• Remove the black printhead, wipe the nozzle area with a lint-free cloth.
• Reinsert the printhead and run a Printhead Alignment.
