Blue Ink not working

[S54213]

My HP OfficeJet Pro 6978 blue ink isn't working...I can print black but anything color just prints a pink/purple color.  I went through the normal head cleaning options but just kept running through the ink cartridges with no actual progress made.  I erally need some help.

Hi @S54213,

Welcome to The HP Support Community.  

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

I understand the blue ink nozzle in your HP OfficeJet Pro 6978 might be clogged or not functioning properly. Here are a few steps to troubleshoot and hopefully resolve the issue:
 

Check Ink Levels: Make sure that the blue ink cartridge is not empty or low. Sometimes even a small amount of ink can cause issues with color printing.

Perform a Printhead Cleaning:

• Go to the printer's control panel.
• Navigate to the "Setup" or "Maintenance" menu.
• Select "Clean Printhead" or a similar option.
• You may need to perform this process a few times to clear any clogs.

Perform a Printhead Alignment:

• From the printer’s control panel, go to the "Setup" menu.
• Select "Printer Maintenance" or "Tools" and choose "Align Printhead".
• Follow the on-screen instructions.

Check for Clogs Manually:

• If cleaning from the menu doesn’t work, you can try cleaning the printhead manually. Remove the printhead and check for any dried ink or debris. Use a soft, lint-free cloth moistened with warm water to gently clean the printhead.

Reinstall the Ink Cartridges:

• Remove the blue ink cartridge and reinstall it. Sometimes a poor connection can cause issues.

Replace the Ink Cartridge:

• If the above steps don’t help, the blue ink cartridge might be defective. Try replacing it with a new one.

Update Printer Firmware: Update the firmware on an HP printer

• Check if there’s a firmware update available for your printer on the HP website. Sometimes updates can fix issues related to printing.
