If the automatic search fails, choose the manual settings method. You will need to enter the network's SSID and security key. Be careful when entering the password: letter case is important, and extra spaces may result in an authorization error.
Setting up WiFi via WPS (if your router supports it)
The fastest way to connect MFP To connect to the network, use WPS (Wi-Fi Protected Setup). This method automatically transmits the password, eliminating the need to enter it manually. Check your router: it should have a physical button with the appropriate marking or icon.

In the printed document, find the section TCP/IPThe device's IP address will be listed here, for example, 192.168.1.45. This address confirms that the printer is on the network. If you see 0.0.0.0 instead of the address, it means the connection to the router is not established.
| Parameter | Normal value | Problem |
|---|---|---|
| SSID | Your network name | Invalid network |
| IP Address | 192.168.x.x | 0.0.0.0 |
| Signal Strength | Good / Excellent | Weak / None |
Using the obtained IP address, you can check the printer's availability through a browser. Simply enter the numbers into the address bar of any browser. If the web configurator page opens, Samsung, which means the connection between the laptop and the printer is established correctly.
Adding a printer to the operating system
After setting up the network, the Windows or macOS operating system should automatically detect the new device. Go to the section Control Panel → Devices and Printers (or Settings → Devices in Windows 10/11). If the printer does not appear automatically, click the button Add a printer.
The system will start searching for available devices. When one appears in the list Samsung SCX-3400 Series, select it, and click "Next." Windows will automatically select the necessary drivers from the update center or use the files already installed.
