Here's what to do if you get the error message "The ScanSnap is turned off" when using the Sansan scanner.
*These steps are also effective if you don't get this particular message but the scanner is not responding.
1. Make sure the Wi-Fi switch (1) on the back of the scanner is set to Off.
2. Unplug the power cords (2, 3) on the scanner/tablet and the adapter (4) and then plug them back in.
3. Unplug the USB cable (5) on the scanner and plug it back in, and use a different USB port on the tablet.
*If you use a docking station, remove and re-attach the tablet (6).
4. Close the scanner cover (7), wait 5 seconds, then re-open it.
5. Restart the tablet (8).
Press the [Power] button in the top right of the scanner app screen and select [Reboot Windows].
If the touch panel doesn't respond, press and hold the power switch until the unit turns off, and then restart it. Click here for more on how to do this.
