Hi @Lue2,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If the yellow ink cartridge in your HP OfficeJet Pro 6978 is not printing green despite cleaning the cartridges, there are a few additional steps you can take to troubleshoot and resolve the issue.

1. Check Ink Levels: Make sure that the yellow ink cartridge has sufficient ink. You can check the ink levels through your printer software or control panel. If the ink level is low, consider replacing the cartridge.

2. Print a Test Page: Print a test page to see if the issue persists. This can help you identify whether the problem is with a specific document or if it's a consistent issue.

3. Align the Printer: Many printers have an alignment function that ensures the printhead is correctly aligned. Check your printer's manual for instructions on how to align the printhead. This can sometimes resolve color-related printing issues.

4. Update Printer Drivers: Ensure that your printer drivers are up-to-date. Visit the HP website to download and install the latest drivers for your OfficeJet Pro 6978.

5. Check for Firmware Updates: Check if there are any firmware updates available for your printer. Firmware updates can address performance and compatibility issues.

6. Perform a Deep Cleaning: Some printers have a deep cleaning function that goes beyond a regular cleaning. Consult your printer manual to see if your model has this option and follow the instructions to perform a deep cleaning.

7. Remove and Reinstall Cartridge: Remove the yellow ink cartridge and reinstall it. Make sure it is securely and correctly inserted. This can sometimes resolve connectivity issues.

8. Inspect for Physical Damage: Check the yellow ink cartridge for any physical damage or leaks. If you find any issues, consider replacing the cartridge.

I hope this helps.

Take care and have a good day.
