Wireless connection of office equipment is a standard that provides freedom of action and eliminates unnecessary wires. Model Samsung SCX-3405W Equipped with a built-in Wi-Fi module, it can be placed anywhere in the room as long as there's a strong router signal. However, initial setup often raises questions for users, especially if the drivers aren't installed correctly or the network has specific security settings.
In this article, we'll take a detailed look at the process of integrating a printer into a local network. You'll learn how to properly prepare the equipment, what software components are required for stable operation, and how to avoid common password errors. The key point is a sequence of actions: first, the device itself is configured, then a connection with the computer is established.
Modern routers often operate in two bands, and older printer models may not be able to detect 5 GHz networks. Therefore, before starting the procedure, make sure your router is broadcasting a signal in the 2.4 GHz band, as the module SCX-3405W Only this standard is supported. Ignoring this fact is the most common reason why a device cannot find available access points.
Preparing equipment and checking network compatibility
The first step is to physically prepare and analyze your network infrastructure. You need to ensure that the router is turned on and providing internet access. The printer should be located within a strong signal range, preferably no more than 5-7 meters from the source during setup. If the device has already been connected to another network, it is recommended to reset the network settings to factory defaults to avoid IP address conflicts.
Pay attention to the indicators on the control panel. The button with the antenna or Wi-Fi icon should be lit or flashing, indicating the module is ready for use. If the indicator is not active, the wireless module may be disabled by software or hardware. In some cases, a brief connection via USB cable is required for initial configuration, although the model 3405W Allows you to configure Wi-Fi directly from the panel.
⚠️ Attention: Make sure MAC address filtering is not enabled on your router. If the security settings prohibit new device connections, the printer will not be able to authenticate, even if the password is entered correctly.
Check your wireless network encryption type. The most common standards WPA2-PSK And WPA3 These are generally supported without issue, but older encryption algorithms (WEP) can cause problems with modern operating systems, even though the printer understands them. It's also important to know the network name (SSID) and password; if the network name uses Cyrillic characters or special symbols, encoding issues may occur, so temporarily rename the network to Latin characters.
Installing Samsung drivers and software
Without specialized software, your computer won't be able to properly interact with the multifunction device. Windows or macOS may recognize the printer as an unknown device, but full scanning and tray management functionality will be unavailable. Therefore, the primary task is to find and install the latest drivers from an official source.
Since the support of Samsung printers was transferred to the company HP, you should now search for drivers on the HP support portal. You'll need a utility Samsung Printer Setup or a complete package Unified DriverDownload the installer corresponding to your operating system version (32-bit or 64-bit is important). During installation, the program will prompt you to select the connection type.
Run the installer and follow the on-screen instructions. When asked about the connection method, select "Wireless Network Connection" or "Wi-Fi." The installer will attempt to find the device on the network. If the automatic search is unsuccessful, the program will offer a temporary connection via USB cable to transfer network settings—this is standard procedure for this series of devices.
⚠️ Attention: Antivirus programs or the built-in Windows firewall may block the installation of the driver's network components. We recommend pausing protection or adding an exception for the Samsung installer during setup.
It's important not to interrupt the installation process. Even if the program seems to freeze while searching for a device, wait a few minutes. Port configuration may be occurring in the background. After successful installation, it's recommended to restart your computer so that all system print services update and register the new device.
Setting up a Wi-Fi connection via the control panel
The most reliable way to connect Samsung SCX-3405W — Use the buttons on the device itself. This method doesn't require a computer and allows the printer to find the network automatically. On the control panel, look for a button with a (Wireless) icon or menu. Pressing this button puts the device into search mode or displays the current status.
To enter the settings menu, press the button Menu, then use the navigation arrows to navigate to the item Network or WirelessIn the submenu that opens, select Wireless On/Off and make sure the value is On. Next, select SSID Setting or Wireless SetupThe printer will begin scanning the air and display a list of available networks.
Find your router's name in the list. If the network is hidden, select the option to manually enter the SSID. After selecting the network, the device will ask for a password (security key). Enter the characters carefully, using the arrow keys to navigate through the characters and the button. OK to confirm each character. After entering the full password, select Apply or OK.
- 📶 If the Wi-Fi indicator is solid, the connection has been successfully established.
- 🔄 A flashing indicator indicates the connection process or an error in the password.
- ❌ Lack of response may indicate frequency incompatibility (check 2.4 GHz).
- 🔒 Authentication errors most often occur due to incorrect letter case in the password.
After successful setup, the control panel may print a Network Configuration Page, which will show the IP address assigned by the router. This document is useful for further diagnostics. Write down the IP address; you'll need it to manually install the printer on the system if the automatic installation fails.
☑️ Checklist for successful setup
Manually configuring IP addresses and ports
Sometimes automatic printer detection on the network fails, especially in complex corporate networks or when using guest VLANs. In this case, you need to manually enter the device's IP address in the driver settings or assign a static IP address to the printer itself so that it doesn't change after a router reboot.
To assign a static address via the web interface (if available) or the printer control panel, go to the menu Network -> TCP/IP. Turn off the mode DHCP (Dynamic Host Configuration Protocol) and proceed to manual parameter entry. You will need: IP address, subnet mask, and gateway.
IP Address: 192.168.1.150Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
The values above are examples. You should use addresses that match your local network. The first three digits of the IP address must match your router's address, and the last digit must be unique (not already occupied by another device) and in the range 2-254.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | The printer's unique address on the network | 192.168.0.55 |
| Subnet Mask | Subnet mask, which determines the size of the network | 255.255.255.0 |
| Gateway | Gateway (router) address | 192.168.0.1 |
| DNS Server | Name server (you can specify the router address) | 8.8.8.8 or 192.168.0.1 |
After changing the settings, the network may be disconnected for a few seconds. Verify that the new IP address is available by running the command ping in the computer's command line. If a response is received from the device, the physical and logical connection is established correctly, and you can begin adding the printer to the OS.
What to do if IP addresses conflict?
If you assign a printer an address that's already occupied by another device (such as a smartphone or laptop), an IP conflict will occur. In this case, one of the devices will lose network access. To avoid this, choose addresses at the end of the range (e.g., above .200), where the likelihood of occupancy is minimal, or reserve an address in the router settings based on the printer's MAC address.
Adding a device to the operating system
The final step is to add the printer to your operating system's device list. In Windows, go to Parameters -> Devices -> Printers and scanners. Click the button Add a printer or scannerIf the system finds the device by name (for example, SCX-3400 Series), just select it and click "Add".
If the automatic search does not yield any results, select the option The printer you need is not listed.In the window that opens, select the item Add a printer by its TCP/IP address or hostnameIn the "Name or IP Address" field, enter the static IP address you set or found in the configuration report (e.g., 192.168.1.150). The system will attempt to discover the device.
In the next step, Windows may prompt you to select a driver. If you have previously installed software from Samsung/HP, select it from the list. If not, click the button Install the driver and specify the path to the previously downloaded files or select a model from the list of manufacturers (Samsung or Hewlett Packard). After installing the driver, the system will prompt you to name the printer; keep the default name or choose a more convenient one, for example, "Samsung Office Wi-Fi."
- 🖨️ For macOS, the process is similar: System Preferences -> Printers & Scanners -> +.
- 🔍 Use the IP and Protocol tab AirPrint or HP Jetdirect for manual input.
- ✅ Be sure to check the "Use when printing" box to make it the default.
After installation is complete, it is recommended to print a test page. This will confirm that data is being transmitted over the network without loss or distortion. If the page prints clearly, then SCX-3405W completely ready for wireless operation.
Troubleshooting and Frequently Asked Questions
During operation, situations may arise where the printer stops responding or its status changes to "Use Offline." This is often due to a change in the router's IP address (if a static IP isn't set) or updating Windows drivers. Check that the IP address in the printer properties matches the device's actual network address.
Another common issue is a weak signal. If the printer is located far from the router or behind thick walls, the data transfer rate may drop, leading to timeouts when printing large documents. In such cases, installing a repeater or moving the router closer to the printing area can help.
⚠️ Attention: Router and operating system settings interfaces are subject to update. Menu item locations or security protocol names may differ from those described in the instructions. Always consult the latest documentation from the manufacturer of your network equipment.
If nothing helps, perform a full network reset on the printer (item Network -> Clear Settings) and repeat the setup procedure again. This often resolves issues with stuck configurations.
Why can't my computer see my Samsung SCX-3405W printer on the network?
The most common cause is that the computer and printer are on different subnets (for example, one device is connected to a guest Wi-Fi network, and the other to the main Wi-Fi network). It's also possible that a firewall is blocking device discovery, or the printer's wireless indicator isn't lit.
Can this printer be connected to 5GHz Wi-Fi?
No, model SCX-3405W The router is equipped with a module that only supports the 802.11 b/g/n standard in the 2.4 GHz band. For this feature to work, the router must be transmitting a signal in this band. If you have a dual-band router, make sure the Smart Connect feature doesn't interfere with the device's ability to find a 2.4 GHz network.
How do I reset my printer's network settings to factory defaults?
Click the button Menu, go to the section Network (Network), find the item Clear Settings (Clear settings) or Reset NetworkConfirm the action. After rebooting, the printer will forget all saved passwords and IP addresses.
What to do if the printer prints garbage instead of text?
This is a classic sign of an incorrectly selected driver (PCL vs. PS or Generic Text Only). Remove the current printer from the system, go to the official website, download the full driver package for your specific model and Windows version, and reinstall it, selecting the correct page description language.
