Why is my printing not printing green or blue color?

Hi @SANTI0110,

Welcome to HP Support Community.

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

If your HP Smart Tank 510 printer is not printing green or blue, it could be due to a few common issues. Here's a step-by-step guide to diagnose and resolve the problem.

Check Ink Levels

• Ensure that the ink levels in the cyan (blue) and yellow tanks are adequate. If the ink levels are low, refill the tanks using the correct HP ink.

Perform a Printhead Cleaning

• Inconsistent or missing colors may result from clogged printheads. Use the printer's maintenance menu or the HP Smart app to perform a printhead cleaning.
• After cleaning, run a print quality diagnostic page to verify improvement.

Check for Air in the Ink Tubes

• Air bubbles in the ink tubes can prevent ink flow. Gently follow the printer manual's instructions to prime the ink system if needed.

Verify Ink Bottle Type

• Confirm that you're using genuine HP ink bottles. Non-HP inks might not mix correctly, leading to color issues.

Align the Printheads

• Misaligned printheads can cause color inaccuracies. Use the printer's maintenance tools to align the printheads.

Inspect the Color Cartridges/Nozzles

• Sometimes, the nozzles or cartridges that deliver ink might be clogged or damaged. Inspect and clean the printhead assembly manually if necessary.

Update Printer Firmware

• Ensure the printer has the latest firmware installed. Check for updates via the HP Smart app or the printer's settings menu.

Test a Different Document

• Print a test page or different document to rule out file-specific issues.

Perform a Factory Reset

• If none of the above resolves the issue, you might need to perform a factory reset. Be sure to back up any settings beforehand.

I hope this helps.

Take care and have a good day.
