Why my scanner does not start scanning even when I press the scan button?
Your network connection could be blocked in the environment where firewall is activated. Adding ScanSnap Manager in the firewall exception may solve your problem (To set firewall exception, refer to the manual of your firewall).
When you add a program in firewall exception, the port that the program uses can receive a contact from outside. Before changing the setting of the firewall, please be aware of the risk involved and perform it on the customer's responsibility. Our company will not be responsible for any damage or failure caused by the change.
