Hi @terbar17,

Welcome to HP Support Community.

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

If your HP ENVY 7640 e-All-in-One Printer's cyan ink is not printing after cleaning the cartridges, here are some troubleshooting steps you can follow.

Check Ink Cartridge Levels

• Ensure the cyan ink cartridge has sufficient ink. Low ink can sometimes prevent printing, even if the cartridge is new or recently cleaned.

Clean the Ink Cartridge Contacts

• Power off the printer and remove the cyan ink cartridge.
• Gently clean the copper-colored contacts on the cartridge and the corresponding contacts inside the printer using a lint-free cloth slightly dampened with water or rubbing alcohol.
• Reinstall the cartridge and check if it prints.

Run the Printer's Ink Cartridge Cleaning Cycle

• From the printer's control panel, navigate to the Setup menu > Tools > Clean Cartridges.
• Follow the instructions to perform a deeper cleaning cycle.

Check for Air Bubbles in the Cyan Cartridge

• Sometimes, air bubbles can block the ink flow. If this is the case, gently shake the cartridge side to side or tap it lightly to remove any air bubbles.

Replace the Cyan Cartridge

• If the cyan ink continues to come out blank after cleaning, the cartridge might be defective or dried out. Try replacing the cyan ink cartridge with a new one and check if this resolves the issue.

Check for Firmware or Software Issues

• Ensure the printer's firmware is up to date. You can check for updates through the printer's control panel or via the HP Smart app.

I hope this helps.

Take care and have a good day.
