Fix HP Scanner Not Working Issue

When your HP printer's scanner stops working, the cause is typically a driver issue, Windows Image Acquisition (WIA) service problem, or connection problem.

Fix 1: Restart WIA Service (Windows)

1. Press Win + R, type services.msc
2. Find Windows Image Acquisition (WIA)
3. Right-click → Restart
4. Also restart Shell Hardware Detection and Remote Procedure Call (RPC)

Fix 2: Run HP Print and Scan Doctor

HP's free tool automatically diagnoses and fixes scanner issues. Download from HP's support site and run the scan fix option.

Fix 3: Update or Reinstall HP Driver

1. Uninstall current HP software from Control Panel > Programs
2. Go to HP's support site, search your model
3. Download HP Easy Start or the full software suite
4. Reinstall and restart

Fix 4: Check HP Scan Software

1. Open HP Smart or HP Scan
2. If the scanner doesn't appear, click Manage → Add a printer or scanner
3. Let the software rediscover your device

Fix 5: Check for Conflicts

Third-party scanning software can conflict with HP's scanner driver. Temporarily disable other scanning apps.

Fix 6: Fix Scanner on Mac

1. Open System Settings > Printers & Scanners
2. Select your HP printer/scanner
3. Click Open Scanner to test
4. If it fails, delete and re-add the printer

macOS uses the ICA (Image Capture Architecture) framework. Open Image Capture app (in Applications) and see if your HP scanner appears there.
