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)

  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.
