HP printers are known for their reliability, but even the best devices can run into issues. One common problem users face is when an HP printer won’t scan documents, either to a computer or via the HP Smart App. Whether you’re using Windows, macOS, or mobile, this guide will walk you through the most effective solutions to get your HP scanner working again.


🔍 Common Reasons Why HP Printers Stop Scanning

Before jumping into the fixes, it helps to understand why the scanning feature might stop working. Common causes include:

  • Outdated or missing scanner drivers

  • Misconfigured scan settings

  • Communication errors between the printer and computer

  • Issues with the HP Smart App or HP Scan software

  • Firewall or antivirus interference

  • USB or Wi-Fi connectivity issues


✅ Step-by-Step Fixes for HP Printer Not Scanning


🧰 Step 1: Restart Everything

Begin with the basics—sometimes a simple reboot resolves temporary glitches.

  1. Turn off the HP printer and unplug it for 30 seconds.

  2. Restart your computer or mobile device.

  3. Reboot your Wi-Fi router (if scanning wirelessly).

  4. Plug in and power on the printer.

  5. Try scanning again.


📡 Step 2: Check the Connection (USB or Wi-Fi)

For your printer to scan successfully, it must be properly connected.

  • USB users:

    • Ensure the cable is securely connected to both the printer and PC.

    • Avoid using USB hubs—plug directly into the computer.

  • Wi-Fi users:

    • Ensure both the printer and the device are on the same network.

    • Check the printer’s screen or HP Smart App to verify network connection.

    • Print a Network Configuration Page to check connectivity.



🔄 Step 3: Reinstall HP Smart or HP Scan Software

Corrupt or outdated software may block scanning functionality.

For Windows:

  1. Uninstall HP Smart or HP Scan from Control Panel > Programs.

  2. Visit https://123.hp.com and download the latest version.

  3. Reinstall and run the software, then try scanning again.

For macOS:

  1. Remove the HP printer from System Settings > Printers & Scanners.

  2. Uninstall the HP Easy Scan or HP Smart app.

  3. Reinstall via the App Store or https://123.hp.com.

  4. Add the printer again and attempt to scan.


🔁 Step 4: Use the HP Print and Scan Doctor (Windows Only)

HP offers a dedicated tool for fixing scan-related issues on Windows.

  1. Download HP Print and Scan Doctor from:https://support.hp.com/us-en/topic/printscandoctor

  2. Open the tool and select your printer.

  3. Click Fix Scanning.

  4. Follow the on-screen instructions to resolve detected problems.

This tool checks for connectivity issues, driver conflicts, and service errors.


🖥️ Step 5: Enable “Scan to Computer” Feature

Many HP printers require this feature to be enabled for scanning from the device panel.

On HP Smart App:

  1. Open HP Smart on your PC or Mac.

  2. Go to Printer Settings > Advanced Settings (EWS).

  3. Under Scan > Scan to Computer, make sure it’s turned On.

  4. Also check if Enable Scan to Computer at Startup is selected.


🔐 Step 6: Check Firewall and Security Software

Firewalls and antivirus software may block scanning communication.

  • Temporarily disable firewall/antivirus during scanning.

  • Add exceptions for:

    • HP Smart App

    • HPScan.exe

    • Twain service or WIA (Windows Image Acquisition)

Try scanning again. If successful, configure permanent exceptions in your security software.



⚙️ Step 7: Update or Reinstall Scanner Drivers

Outdated or corrupt drivers often cause scan failures.

  1. Go to https://support.hp.com.

  2. Enter your printer model and navigate to the Drivers section.

  3. Download the latest Full Feature Software and Driver package.

  4. Install and restart your computer.


📲 Step 8: Scanning from HP Smart Mobile App

If scanning via phone fails:

  1. Ensure your mobile device is on the same Wi-Fi as the printer.

  2. Open the HP Smart App and tap Scan.

  3. If “Scan” is grayed out, remove and re-add the printer.

  4. Restart the app or reinstall it from the App Store or Google Play.


🧩 Additional Tips for Scanning Issues

  • Try a different scanning app (e.g., Windows Fax and Scan, macOS Preview).

  • Test from another device to rule out hardware failure.

  • Check for printer firmware updates via the HP Smart App.

  • Check scanner glass or ADF for physical issues like jams or dust.


📝 When to Contact HP Support

If none of the above methods work, it may be a hardware-related issue such as:

  • Scanner light failure

  • Internal component damage

  • Firmware corruption
