My scanner has stopped working

[Annobanano]

My scanner, which was working perfectly, now is extremely sluggish, stops mid-scan, or does not scan at all. The ONLY thing that looks odd, is that the color copy button is lit, but the b&w is not.

@Annobanano, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Thanks for the detailed description—let's troubleshoot your HP ENVY 6055 scanner issue on macOS step-by-step:

✅ Quick Checks First

1. Restart Everything
   • Power off your printer, unplug it for 1 minute, then power back on.
   • Restart your Mac as well.
2. Check Connection
   • If you're using Wi-Fi, ensure both the printer and Mac are on the same network.
   • Try scanning over USB temporarily to isolate if the issue is Wi-Fi related.
3. Try a Hardware Copy
   • Place a document on the scanner bed and press the Color Copy button.
   • Then try the Black & White Copy button.
   • If B&W is unresponsive or slow, it may be hardware-related.

🛠️ On Your Mac

1. Reset the Printing System
   (This won’t delete files, but will remove all printers/scanners temporarily)
   • Go to System Settings > Printers & Scanners.
   • Right-click (or Control-click) the printer list > Reset printing system.
   • Re-add your HP ENVY 6055 using +.
2. Use HP Smart App (Official)
   • Download from HP Smart for macOS.
   • Reconnect your printer through the app.
   • Use Scan > Flatbed Scanner and check if scanning works better here.
3. Check for Updates
   • In the HP Smart app, go to Settings > Printer Settings > Advanced Settings.
   • Check for a firmware update.
   • On your Mac, go to System Settings > General > Software Update.

🧹 Optional: Clean Out Old Drivers

Sometimes leftover drivers cause issues:

• Go to ~/Library/Printers/ and /Library/Printers/ folders and remove HP related files.
• Reinstall the HP Smart app after that.

🟡 About the Copy Button Lighting

• It’s normal for one copy button to be lit—it typically lights up the last used mode (e.g., color copy).
• If the B&W copy button doesn’t respond at all or blinks strangely, that might suggest:
  • A hardware issue with the button.
  • Or a firmware/software issue confusing the scanner function.

🔚 If Nothing Works

• Try scanning from Preview > File > Import from Scanner or Image Capture app.

I hope this helps. 

Take care and have a good day.
