Hi @johnmoyer,

Welcome to HP Support Community.  

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

I understand you are facing a print quality issue with your  HP OfficeJet Pro 6978 printer isn't printing with the blue cartridge despite cleaning it multiple times, there are a few steps you can take to troubleshoot the issue:

• Check Ink Levels: Ensure that the blue cartridge has sufficient ink levels. You can check this through the printer's control panel or the HP printer software on your computer.
• Use Genuine Cartridges: Ensure you're using genuine HP cartridges. Sometimes, third-party or refilled cartridges may cause compatibility issues.
• Verify Cartridge Installation: Make sure the blue cartridge is properly installed in the printer. Remove it and reinsert it carefully to ensure it's seated correctly.
• Clean the Cartridge Contacts: Turn off the printer and remove the blue cartridge. Wipe the electrical contacts gently with a lint-free cloth dampened with distilled water. Be careful not to touch the nozzles. Reinsert the cartridge and turn the printer back on.
• Printer Maintenance: Run the printer's built-in maintenance functions, such as the printhead cleaning utility. You can usually find this option in the printer's settings menu.
• Update Printer Drivers: Ensure that your printer drivers are up to date. Sometimes, outdated drivers can cause printing issues. You can download the latest drivers from the HP website.
• Reset the Printer: Try resetting the printer to its factory settings. This can sometimes resolve software-related issues that are preventing the blue cartridge from printing.
