Multifunctional device integration Samsung SCX-3405W Connecting the printer to a local network provides access to printing and scanning from any computer or mobile device without the need for cables. The wireless module in this model ensures stable data transfer, but initial configuration can often be challenging for users unfamiliar with network protocols.
The setup process requires careful attention to detail, as the device has a minimalist interface without a full-screen display. You'll have to rely on blinking indicators and a sequence of button presses to activate the desired operating modes.
In this guide we will cover all possible connection methods, including using technology WPS, installation via USB cable with subsequent conversion to wireless mode, as well as manual configuration of IP addresses for corporate networks.
Equipment preparation and compatibility testing
Before you begin, make sure your wireless router is working properly and assigning IP addresses to connected clients. Printer Samsung SCX-3405W supports Wi-Fi 802.11 b/g/n standards, operating exclusively in the 2.4 GHz range, which is a critical feature for modern dual-band routers.
Place the printer in an area with a strong signal, ideally within line of sight of the router's antennas. Walls, metal cabinets, and household appliances can significantly weaken the signal, resulting in lost data packets when printing large documents.
You'll need to know your wireless network name (SSID) and password. If your router has MAC address filtering enabled, find the sticker on your printer or print a configuration report to whitelist the device's address.
- 📶 Make sure your router is broadcasting in the 2.4 GHz range, as this printer cannot see the 5 GHz band.
- 🔌 Check if there is a free USB port on your computer for initial driver setup.
- 📄 Print a test page or network report to ensure the MFP itself is working properly.
⚠️ Note: If your router uses "WPA3 Only" mode or a hidden SSID, the printer may not detect the network automatically. Temporarily change your router's security settings to WPA2-PSK (AES) for successful pairing.
⚠️ Note: Driver interfaces and router web interfaces may differ depending on the firmware version. If the menu item described is missing, look for a similar section in your equipment's documentation.
The fastest method: using the WPS button
Technology Wi-Fi Protected Setup Allows you to connect devices without entering a password, using a secure communication channel. This is the easiest method if your router supports this feature and has a physical activation button.
Press and hold the WPS button on your wireless router for 2-3 seconds until the security light starts blinking. Immediately after, press and hold the WPS button on your printer's control panel. Samsung SCX-3405W Press and hold the wireless button (antenna icon) until the lights flash in a specific sequence.
The device will automatically detect the router and exchange encryption keys. The process takes no more than two minutes, after which the printer's Wi-Fi indicator should turn solid blue or green, indicating a successful connection.
If the LEDs flash rapidly and continuously but don't turn solid, the connection hasn't been established. In this case, check if the router has timed out and repeat the procedure, performing the steps more quickly.
Setup via USB cable and software
If automatic network detection doesn't work, the most reliable method is to use an installation disc or a driver package downloaded from the official website. This method allows you to programmatically transfer Wi-Fi settings from your computer to the printer.
Run the installer Samsung Printer Setup and follow the on-screen instructions. When the program asks for the connection type, select "Wireless." At a certain point, the installer will ask you to connect the device directly to the computer via a USB cable.
After connecting the cable, the program automatically reads your PC's current network settings and prompts you to transfer them to the printer. All you need to do is confirm your network selection from the list and enter the password if it isn't pre-populated.
☑️ Installation Preparation Checklist
After successfully transferring the configuration, the driver will prompt you to disconnect the USB cable. From this point on, the computer will continue communicating with the printer over the air. Make sure both devices are on the same subnet, especially if you have a complex home network with multiple routers.
What should I do if my computer doesn't see my printer after setup?
Make sure your Windows firewall or antivirus software isn't blocking printing ports. Try temporarily disabling the firewall and performing a test print. Also, make sure the network type in Windows is set to "Private" and not "Public."
Manual configuration of IP address and network parameters
Advanced users or corporate network users may need to manually assign a static IP address. This will prevent situations where, after a router reboot, the printer receives a new address and computers lose access to it.
To access the printer's web interface, you need to know its current IP address. Print a network configuration report by pressing the stop button or a combination of buttons on the panel (depending on the firmware version), typically a long press on the wireless button.
Enter the received IP address into the browser's address bar. If the page doesn't open, use a utility. SyncThru Web Service or a network scanner. In the navigation menu, go to the section Network -> TCP/IP and select the mode Static instead of DHCP.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | The unique address of a device on the network | 192.168.1.150 |
| Subnet Mask | Subnet mask (usually default) | 255.255.255.0 |
| Gateway | Gateway (router) address | 192.168.1.1 |
| DNS Server | Name server (you can specify your provider's DNS) | 8.8.8.8 |
After applying the settings, the printer may reboot the network module. You will need to re-add the print port in the operating system, specifying a new static address so the computer can find the device.
Mobile printing and additional features
Modern mobile device operating systems allow you to print documents and photos directly, bypassing the computer. Samsung SCX-3405W The AirPrint (for iOS) and Mopria (for Android) protocols are relevant.
Make sure your smartphone is connected to the same Wi-Fi network as your printer. In the Photos or Files app, select the desired document, tap the Share button, and find your printer in the list of available devices.
For advanced features like scanning to the cloud or adjusting paper settings, you can use the app. Samsung Mobile PrintIt allows you to manage the print queue and monitor the toner level in the cartridge in real time.
- 📱 For iPhone, no additional driver installation is required; AirPrint technology is built into the system.
- 🤖 On Android, you may need to install the "Mopria Print Service" plugin from Google Play.
- ☁️ The "Scan to PC" function requires installation of the appropriate software on the computer and setting up shared folders.
⚠️ Note: When using a guest Wi-Fi network (Guest Network) on a router, mobile devices may not see the printer due to client isolation. Use the main network for printing.
Diagnosis and solution of typical problems
Even with proper setup, wireless module malfunctions may occur. If your printer stops responding to print requests, first check the control panel.
A common issue is when the router changes the Wi-Fi channel to a less congested one that isn't supported by the printer (for example, channels 12-14 in some regions). Set the channel in the router settings to a value between 1 and 11.
If the device is stuck in the "Disconnected" or "Offline" status, try resetting the printer's network settings. This usually requires pressing and holding the wireless button and the cancel button (the cross) simultaneously for 10-15 seconds until the indicators reset.
In complex cases, updating the device's firmware may help if the manufacturer has released new versions to improve compatibility with modern routers. You can download the latest version from the official support portal.
Why doesn't the printer see the 5 GHz network?
The Wi-Fi module in the SCX-3405W model does not physically support the 5 GHz frequency band. It only operates in the 802.11 b/g/n standard at 2.4 GHz. You need to enable 2.4 GHz network broadcasting in your router settings.
How to find out the IP address of a printer without printing a report?
You can use the Status Monitor utility, which is installed with the drivers. The IP address is also often displayed in the list of connected clients in your router's web interface.
Is it possible to connect a printer via Wi-Fi Direct?
Yes, the SCX-3405W model supports Wi-Fi Direct, which allows you to connect to the printer directly without a router. To do this, activate the mode in the print menu and find the network with the "Direct-XX-SCX-3405 Series" prefix on your device.
