Before creating the shared folder, check the following.
The scanner is connected to the network where it can access the computer where the shared folder will be created.
A multi-byte character is not included in the name of the computer where the shared folder will be created.
When a multi-byte character is included in the computer name, saving the file to the shared folder may fail.
In that case, change to the computer that does not include the Multi-byte character in the name or change the computer name.
When changing the computer name, make sure to confirm with the administrator in advance because it may affect some settings, such as computer management, resource access, etc.
