@Jimvs, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Check Ink Levels

Go to the printer’s control panel:

Tap Ink icon or go to Settings > Ink Levels.

Ensure there’s sufficient black ink.

Print a Diagnostic Page

This helps identify if the issue is software, hardware, or ink-related:

On the printer:
Setup > Printer Maintenance > Print Quality Report

Check if black ink appears on the report.

Clean the Printhead

Even with a good cartridge, dried ink or clogged nozzles can cause this.

Go to Settings > Printer Maintenance > Clean Printhead.

Run it twice if needed.

Print another Print Quality Report.

Run HP Smart:

• Download and run the HP Smart. Follow the prompts to diagnose and fix common printing issues.
• Refer: Use Diagnose & Fix in HP Smart to repair common printing issues (Windows, macOS) | HP® Support

Update Printer Firmware (Update the firmware on an HP printer | HP® Support)

• Go to the HP Customer Support - Software and Driver Downloads page. Enter your printer model number and search for the latest firmware update. Follow the instructions to download and install the firmware update.

I hope this helps.

Take care and have a good day.
