Multifunctional device Samsung SCX-3405W It remains a popular choice for small offices and home workstations due to its reliability and wireless printing capabilities. However, initial setup of the router connection often presents difficulties for users inexperienced with network protocols. Unlike modern touchscreen models, it is controlled via button combinations, requiring a clear understanding of the sequence of actions.
Successfully integrating a printer into a local network allows you to print documents from any device, including smartphones and tablets, without the need for a constant USB cable connection. This significantly improves mobility and ease of use in the office. In this article, we'll cover all current connection methods, from automatic driver installation to manual IP address configuration.
Before starting the procedure, make sure that your router is working properly and is distributing the Internet, and that the printer itself is filled with toner. Critical Know your Wi-Fi network password, as it will be required to authorize the device in the router's security system. Without this information, further steps will not be possible.
Preparatory stage and equipment testing
The first step to reliable operation is properly preparing the physical environment. Make sure the MFP is located within a strong wireless network signal range. Walls, metal structures, and household appliances can create interference, reducing data transfer speeds or causing connection interruptions when printing large documents.
Turn on the device and wait for the warm-up cycle to complete. The Ready light on the control panel should be lit. If you were previously using a USB connection, the computer may automatically detect the device, but switching to Wi-Fi will require a full network reset or an installation disc.
⚠️ Please note: The SCX-3405W model only supports the WPA2-Personal security standard. If your router is configured to use the legacy WEP or corporate WPA2-Enterprise security standard, the printer may not detect the network or may refuse to connect.
To install the software, you will need the original installation disc or internet access to download the latest driver version from the manufacturer's official website. Using third-party driver builds may result in unstable network functionality.
Automatic setup via installation disk
The easiest way to activate the wireless module is to use the included software. Insert the disc into your computer's drive or run the downloaded installation file. The software will automatically detect the device model and offer connection options.
Select "Wireless Connection" in the installer's main menu. The system will offer several options. If you're connecting the device for the first time, select "Use a USB cable to connect." This will allow the program to copy the Wi-Fi settings from your computer directly to the printer.
- 📡 Connect the MFP to your computer via a USB cable and wait until it is detected by the system.
- 💻 Run the setup program and follow the on-screen instructions, selecting the "Wireless Network" connection type.
- 🔑 Enter your Wi-Fi network password in the appropriate field when the program asks for security information.
- 🔄 After transferring the settings, disconnect the USB cable when prompted by the program.
The process takes a few minutes. During this time, encryption keys are exchanged between the router and the printer. After the driver installation is complete, the device should automatically enter network command mode.
☑️ Checking readiness for installation
If the automatic setup was successful, the wireless indicator on the device's panel should glow solid blue. A blinking indicator indicates the network search is in progress or there are configuration errors.
Using WPS technology for a quick start
Many modern routers are equipped with a function WPS (Wi-Fi Protected Setup), which allows you to connect devices without entering a password. This makes life much easier if you don't want to manually enter a complex security key or if your computer keyboard is inaccessible.
To use this method, locate the WPS button on your router. It may be physical or software-based, accessible through the admin web interface. Press this button.
What to do if there is no WPS button on the router?
If there's no physical button, access your router settings through a browser (usually 192.168.0.1 or 192.168.1.1). Find the Wireless or Wi-Fi section and activate the WPS function programmatically. This mode is limited to 2 minutes.
Within two minutes of activating the mode on the router, press and hold the button WPS on the printer control panel Samsung SCX-3405W within a few seconds. The Wi-Fi indicator will begin to flash, indicating that the device is searching and pairing.
Once the connection is successful, the indicator will stop flashing and remain solid. This method only works on networks with WPA/WPA2 encryption and is not supported if WPS is disabled on the router or if MAC address filtering is enabled without prior registration.
Manually configuring the network address and drivers
On corporate networks or if the router's DHCP server is unstable, it is recommended to assign a static IP address to the printer. This will prevent situations where the device's address changes after a router reboot, causing computers to lose connection.
First, you need to find out the printer's current IP address. Click the button WPS on the device's control panel and hold it for more than 5 seconds (up to 10 seconds) until the wireless indicator starts blinking. The printer will print a network configuration report, which will display the current IP address.
Enter this address into the address bar of your computer's browser. This will open the SyncThru™ Web Service printer management web interface. Go to "Network" → "Wireless" → "TCP/IP." Here you can switch the mode from DHCP to Static and enter the address manually.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | The unique address of a device on the network | 192.168.1.55 |
| Subnet Mask | Subnet mask (usually default) | 255.255.255.0 |
| Gateway | Gateway (router) address | 192.168.1.1 |
| DNS Server | Domain Name Server | 8.8.8.8 |
After applying the settings, you must reinstall the driver on the computers, specifying the new static address. This will ensure a stable connection regardless of address redistribution on the local network.
Installing drivers on a computer and mobile devices
Once the printer is connected to the router, you need to configure the client devices. For computers running Windows or macOS, you will need a full driver package. Download the universal driver. Samsung Unified Driver from the official support site.
During installation, select "Add a device" and select "Search for a wireless device." The program will find the printer on the network using the IP address or hostname you specified. Make sure your computer and printer are on the same subnet.
For Android and iOS mobile devices, use the app Samsung Mobile Print Or the operating system's standard printing service. Modern versions of Android (starting with 4.4) and iOS have built-in printing support, but for advanced features (scanning), it's better to use the proprietary software.
- 📱 Make sure your smartphone is connected to the same Wi-Fi network as the printer.
- 🖨️ Open a document or photo and select "Print" from the menu.
- 🔍 Select from the list of detected devices SCX-3405 Series.
- ✅ Confirm the settings and start printing.
⚠️ Important: If you're using a guest Wi-Fi network on your router, devices on it may be isolated from the main network where the printer is located. Client Isolation must be disabled for printing to work properly.
Diagnosis and solution of common problems
Even with proper setup, problems may still occur. These are most often related to changes in router settings or IP address conflicts. If your printer stops responding, first check the panel display.
If the Wi-Fi indicator is blinking, try rebooting the router and printer. This is often caused by a frozen network module in the MFP. It's also worth checking whether the router's security settings have been automatically updated, which could have changed the password or encryption type.
If persistent errors occur, reset the printer's network settings. To do this, turn off the device, hold down the button WPS and turn on the power by holding the button for about 10 seconds until you hear a characteristic sound signal or the behavior of the indicators changes.
If nothing helps, use the network utility ping To check if the device is accessible, open the command prompt and enter ping 192.168.1.XX (where XX is the printer address). The lack of a response indicates a physical connection failure or a firewall blocking the connection.
How do I reset my network settings to factory defaults?
Turn off the printer. Press and hold the WPS button. Turn on the printer while still holding the button. Hold it for about 10 seconds until all the lights flash simultaneously. This will reset the network settings to factory defaults.
