1. Prepare the printer and network before setup

Before you start connecting, make sure that your Samsung SCX-3400 and the network meet the minimum requirements. Skipping this step often results in errors like "cannot find printer" or "no network connection."

Here's what you need to check:

• 🔌 Printer power supplyThe device must be plugged into a power outlet and in working order (the power indicator is green). If the printer is newly unpacked, allow it 1-2 minutes to initialize.
• 📶 Wi-Fi router: The router must support the standards 802.11b/g/n on frequency 2.4 GHz (the printer does not work with 5 GHz). Make sure the network is visible (not hidden) and running in network mode. WPA2-PSK (AES).
• 📱 Tuning device: Prepare a PC with Windows/macOS or a smartphone with Android/iOS. It must have the software installed. Samsung Easy Printer Manager (you can download it from official website).
• 📡 Printer locationPlace the MFP no more than 5 meters from the router. Walls, metal objects, and other electronic devices may cause interference.

Pay special attention to your router settings. If your network uses WPA3, 802.11ac (Wi-Fi 5) or sharing a guest network, the printer may not connect. In this case, temporarily switch to WPA2 Or create a separate network for the device. Also, check if the MAC address filter is enabled on your router—this could block new devices from connecting.

⚠️ Attention: If your router has dual band (2.4 GHz + 5 GHz under one name), the printer can automatically connect to 5 GHz, which will result in an error. Manually separate the networks in the router settings or disable 5 GHz during setup.

1. Click the button Menu on the printer panel. Use the arrows ↑/↓ for navigation and OK for selection.

2. Go to the section Network → Wireless → Wireless Setup Wizard.

3. Select Infrastructure (connection to a router) or Wi-Fi Direct (direct connection to the device). The first option is suitable for most tasks.

4. The printer will begin scanning for networks. Find your network in the list and select it using OK.

5. Enter your Wi-Fi password. Use the arrow keys to move between symbols and OK to confirm. Letters are entered in uppercase by default - to change the case, press #.

6. Confirm your password and wait for the message ConnectedAt this stage, the printer will receive an IP address from the router.

If the printer does not find your network, try entering its name manually: in the menu Wireless select Manual Setup → SSID and enter the network name (case-sensitive!). Then proceed to enter the password.

The printer is connected to a 220V network. The router supports 2.4 GHz. The network is not hidden (the "hidden SSID" mode is disabled). The Wi-Fi password is at hand. Samsung Easy Printer Manager software is installed.

After successful connection, print network report to check the parameters. To do this, press and hold the button Wi-Fi (or Wireless) within 5 seconds. In the report, pay attention to:

• 🔢 IP address: Must be within your local network range (eg. 192.168.1.x).
• 📡 SSID: Must match your network name.
• 🔒 Security: Must be specified WPA2-PSK.
• 📶 Signal Strength: The signal strength is at least 70%. If it's lower, move the printer closer to the router.

⚠️ Attention: If the network report indicates the status Ad-hoc instead of Infrastructure, then the printer is connected in Wi-Fi Direct mode. This mode is not suitable for printing from multiple devices - repeat the setup, selecting Infrastructure.
