Hi @JuliaJules80,
Welcome to The HP Support Community.
Thank you for posting your query, I will be glad to help you.
I understand the Diagnose & Fix feature in the HP Smart app may not be available for certain printers or in some regions. Here are a few things you can try to resolve the issue:
1. Update HP Smart App
Ensure you have the latest version of HP Smart installed on both your iPhone and HP PC:
- On your iPhone, go to the App Store → Search for HP Smart → Tap Update (if available).
- On your HP PC, go to the Microsoft Store → Search for HP Smart → Click Update (if available).
2. Check If Your Printer Supports Diagnose & Fix
Not all HP printers support this feature. Try using HP Print and Scan Doctor on your PC instead:
- Download HP Print and Scan Doctor from HP’s official website.
- Run the tool and follow the on-screen instructions to diagnose issues.
3. Reinstall HP Smart App
- On iPhone:
- Press and hold the HP Smart app icon → Tap Remove App → Delete.
- Go to the App Store and reinstall HP Smart.
- On HP PC:
- Open Settings → Apps → Installed apps → Find HP Smart → Click Uninstall.
- Restart your PC and reinstall HP Smart from the Microsoft Store.
4. Check HP Smart Account & Region
Sign out and sign back into HP Smart to check if it resolves the issue. Some features might not be available based on your HP Smart account region.
I hope this helps.
Take care and have a good day.
