Hi @aminadwani, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Air bubbles in the ink pipes of your HP Ink Tank Wireless 419 printer can cause inconsistent color printing or missing colors. Here’s how to resolve the issue:

Step 1: Check Ink Levels

Ensure that the ink tanks have enough ink. If low, refill them with genuine HP ink.

Step 2: Remove Air Bubbles from Ink Pipes

To remove air bubbles, follow these steps:

Perform a Power Cycle:

• Turn off the printer and unplug it for 5 minutes.
• Plug it back in and turn it on.

Run a Printhead Cleaning Cycle:

• Open HP Smart or HP Printer Assistant on your PC.
• Navigate to Printer Maintenance → Clean Printhead.
• Run the cleaning process up to three times, if needed.

Manually Prime the Ink System (if needed):
If air bubbles persist, manually prime the ink system:

• Open the ink tank access door.
• Use a syringe (if available) to gently pull ink from the printhead area.
• Ensure ink flows smoothly in the pipes without gaps.

Step 3: Check for Clogged Printheads

If colors are still not printing properly:

• Print a Print Quality Diagnostic Page from Printer Maintenance.
• If colors are missing or faded, soak the printhead in warm water for 5-10 minutes.
• Dry it thoroughly and reinstall it.

Step 4: Align the Printhead

• Use HP Smart or HP Printer Assistant to align the printhead under Printer Maintenance.

I hope this helps. 

Take care and have a good day.
