I have refilled my ink from HP ink bottles. My printer is not recognising that the ink tanks are full and comes back to telling me to fill the tanks.

Hi @diamond2579 ,

Welcome to The HP Support Community.  

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

I understand you are facing an issue with your HP Smart Tank 7605 is not recognizing that the ink tanks are full after refilling them, follow these steps to resolve the issue:

1. Ensure Proper Refilling Process

• Double-check that you used the correct HP ink bottles compatible with the Smart Tank 7605.
• Confirm that the ink bottles were fully emptied into the corresponding tanks, with no air bubbles or gaps in the ink flow.

2. Clean the Ink Tank Sensor

• Turn off the printer and unplug it.
• Locate the ink level sensors on the side of the tanks (usually visible from the transparent part of the tank).
• Gently clean the sensors and the tank area with a soft, lint-free cloth to ensure there’s no ink residue blocking the sensors.

3. Restart the Printer

• Plug the printer back in and turn it on.
• Allow the printer to initialize and check if it updates the ink levels.

4. Manually Update Ink Levels

• Open the HP Smart app on your Windows 11 PC.
• Navigate to Printer Maintenance or Printer Tools.
• Look for an option to manually reset or update the ink levels.

5. Perform a Printer Reset

• Turn the printer off.
• Disconnect the power cord from the back of the printer and wait for 60 seconds.
• Reconnect the power cord and turn the printer back on.
• Check if the ink levels are now recognized.

6. Update Printer Firmware

• Ensure that the printer’s firmware is up to date.
• Download and install the latest firmware from the HP Support Website for your printer model.

7. Calibrate the Printer

• Use the Printer Settings menu on the printer’s control panel to run a calibration or alignment process.
• This can sometimes trigger the printer to reevaluate ink levels.

I hope this helps. 

Take care and have a good day.
