‘Unable to Connect with ScanSnap’ error in Windows

After investigating this particular issue, it turns out that there are several different underlying issues that might be responsible for the apparition of this error code. Here’s a list of potential culprits that might trigger the ‘Unable to connect with ScanSnap’ error:

  • Common Spooler service inconsistency – More often than not, you can expect to encounter this particular issue in those instances where you’re actually dealing with a glitched Spooler service. If this scenario is applicable, you should be able to fix the issue temporarily with a simple restart.
  • The Windows Image Acquisition service is not allowed to interact with your desktop – By far, the most common cause that will produce this error is an instance in which the WIA (Windows Image Acquisition service) is not permitted to interact with the computer. In this case, you can fix the issue by using the Services utility to allow the WIA service to interact with your desktop.
  • A different imaging device is controlling the ScanSnap utility – If you have multiple imaging devices installed on the computer that is triggering this issue, it’s likely that a conflicting driver is taking over ScanSnap. If this scenario is applicable, you can fix the issue by disabling every non-relevant imaging device that you don’t need when using your Fujitsu scanner using Device Manager.
  • Outdated ScanSnap Home version – If you’re using a severely outdated ScanSnap version, it’s possible to see this error because the version you’re using is not fully compatible with your operating system. If you find yourself in this situation, uninstalling the current version before upgrading to the latest build should allow you to fix the issue.

Now that you are familiar with every situation that might end up causing this error, here’s a list of verified methods that will allow you to fix the issue:
