## Basic operation

- **Detection scanner**


​	After the scanning software is opened, it will automatically detect the scanner connected directly through USB or set up a network connection.

**Note: when the device is not detected, please confirm whether the corresponding driver has been installed or whether the USB cable used matches. Mixing will lead to unknown errors, such as IO errors**

- **Install Scanner Driver**


​	After the scanner software is opened, it will automatically detect scanners connected directly through USB or set up network connection. If no available devices are detected, a detection program for devices without drivers will be triggered. If a scanner device with drivers that can be installed is found, the corresponding driver will be recommended for automatic installation.
