If you are experiencing issues with entering the PIN during the installation of HP Smart software, here are a few steps that you can follow to resolve the problem:

Double-check the PIN: Ensure that the PIN is entered correctly. Verify that you are distinguishing between similar-looking numbers and letters, such as '0' and 'O', '1' and 'I', etc.

Locate the PIN accurately: The PIN is usually located on a sticker inside the cartridge access area or printer door. Make sure that you have identified the correct label and PIN.

Check for updates: Make sure you are using the latest version of the HP Smart app. You can download it from the appropriate app store or HP's official website.

Try alternate methods: If the PIN continues to show as invalid, try installing the software using an alternative method, such as setting up the printer using Wi-Fi Direct if your model supports it.  

Hope this helps! 

Take care, and have an amazing day!
