MFP Samsung SCX-3405W It remains one of the most popular home office devices due to its reliability and affordable consumables. However, despite the "W" in its name, which implies wireless network support, initial setup of this printer often presents difficulties for users. Unlike modern touchscreen models, the interface is limited to a two-line display and a set of buttons, requiring an understanding of menu logic.
The main difficulty is that the printer doesn't have a built-in screen for selecting a network from a list, like smartphones or laptops. You'll have to manually enter the SSID and password using only the navigation buttons, or use alternative synchronization methods. Proper setup wireless module will open access to printing from any device in the house without the need to pull long USB cables.
In this guide, we'll cover all available connection methods in detail, focusing on Android and iOS mobile devices. You'll learn how to avoid common password errors and why your printer might not see your network even with the correct router settings.
Preparing for wireless setup
Before you begin configuring the network module, you need to ensure your equipment is ready for use. First, check that the router is turned on and providing internet access, and that the printer has toner and paper in the tray. It's important to understand that Samsung SCX-3405W supports only the standard 2.4 GHz, so if your router only broadcasts 5 GHz, the device will simply not be detected by the network.
It's also critical at this stage to install drivers on the computer from which the initial configuration will be performed if you plan to use the WPS method or manual entry via a PC. Although connecting to the phone is possible without a PC, having a computer on hand significantly simplifies the diagnostic process if errors occur.
⚠️ Attention: Make sure that the printer cartridge is original or a high-quality replacement. Some models chips may block the device from operating when attempting to configure it if the toner level is determined to be critical.
Place the MFP close to the router during setup. The signal must be stable to avoid interruptions in the encryption key exchange process. After successful configuration, you can move the device to any convenient location within the Wi-Fi coverage area.
Using the WPS method for quick synchronization
The easiest way to connect Samsung SCX-3405W to the network is technology WPS (Wi-Fi Protected Setup). This method allows you to transfer security settings automatically, eliminating the need to manually enter a complex password using the printer's control panel buttons. Most modern routers support this feature, making the process extremely fast.
First, locate the WPS button on your router. It may be a physical button or a software button accessible through the router's web interface. On the printer's control panel, press the button. WPS and hold it for a few seconds until the wireless indicator starts blinking. This means the device is in connection standby mode.
Immediately after this, press the corresponding button on the router. If you use a physical button, you usually need to hold it for 2-3 seconds. Within a minute, the printer and router will exchange data, and the Wi-Fi indicator on the MFP will turn solid, indicating a successful connection. local network.
- 📶 Press and hold the WPS button on the printer until the indicator light flashes.
- 🔌 Activate WPS mode on your wireless router.
- ⏳ Wait until the Wi-Fi indicator stops flashing and remains on continuously.
- 🖨️ Print a configuration report to verify that you have received an IP address.
If the indicator continues to flash or is red, the connection has not been established. In this case, check if the connection timeout has expired (usually 2 minutes) and try again. Sometimes you need to reboot the router if it's overwhelmed with connection requests.
Manual network setup via computer
If the automatic method doesn't work or your router doesn't support WPS, you'll need to use manual setup. To do this, you'll need a computer with a USB cable connected to the printer, or an installation disc (or a driver downloaded from the official website). Run the driver installation program. Samsung Unified Driver and select the connection type "Wireless Network Connection".
During installation, the program will prompt you to select a network setup method. Select "Use a USB cable to set up a wireless network." The system will prompt you to connect the MFP to your computer via USB, even if you plan to use Wi-Fi only. This is necessary to transfer router settings directly to the printer module.
The program will detect available Wi-Fi networks. Select your router from the list and enter the password. The drivers will then transfer the parameters to network module printer. Once the device confirms receiving the settings, you can disconnect the USB cable—the printer will continue to operate via Wi-Fi.
⚠️ Important: When manually entering the password, pay attention to the case of the letters. A single letter error will cause the router to reject the connection, and the printer will try to connect endlessly without success.
☑️ Check before manual configuration
In some cases, antivirus software or Windows Firewall may block the setup process. If the setup program freezes while searching for networks, try temporarily disabling the protection or adding an exception for the installer. SamsungAfter successful setup, don't forget to reset your security settings to their original state.
Connecting a smartphone via Samsung Mobile Print
To print directly from your phone or tablet, you need to use a dedicated app. For devices Samsung SCX-3405W the optimal solution is an application Samsung Mobile Print, available on Google Play and the App Store. It not only allows you to print documents and photos but also scan images directly to your smartphone.
Before launching the app, make sure your phone is connected to the same Wi-Fi network you connected the printer to in the previous steps. If the printer isn't yet configured, some versions of the app offer a "Wi-Fi Direct" or direct setup feature, but for stable operation, it's best to first configure the MFP via a PC or WPS.
Launch the app and click the "Add Printer" button. The program will automatically scan the network and find an available device. If a printer is found, tap its name to pair it. Now you can open documents, photos, or web pages and print them with just a few taps.
- 📱 Download and install the Samsung Mobile Print app.
- 🔗 Make sure your phone and printer are on the same Wi-Fi network.
- 🔍 Click "Add Printer" and select the device from the list.
- 📄 Select the file to print and adjust the settings (copies, scale).
The app's functionality allows you to change page orientation, select paper size, and choose the number of copies. A scanning function is also available: you can control the MFP remotely, initiating scans and receiving finished files directly to your phone's gallery.
What should I do if the app doesn't see the printer?
If the automatic search doesn't yield results, try adding the printer manually by IP address. To do this, find the IP address by printing a network configuration report (press the Menu button on the printer -> Report -> Network Config). In the app, select "Add Manually" and enter the resulting address, for example, 192.168.1.55.
Setting up Wi-Fi Direct for printing without a router
A unique feature of the model Samsung SCX-3405W is technology support Wi-Fi DirectThis feature allows you to create a direct wireless connection between your phone and printer without using a router. This is especially useful in offices where corporate Wi-Fi access is limited, or at home if the internet is temporarily down.

WPS and hold it for more than 5 seconds until the Wi-Fi Direct indicator lights up (usually a combination of indicators or a specific blinking pattern described in the instructions). After this, a device with a name containing "Direct" or the printer model will appear in the list of available Wi-Fi networks on the phone screen.
Connect to this network. The default password is usually printed on a sticker on the back of the device or in the configuration report. Once connected, the phone will receive the printer's IP address, and you'll be able to print via the app even if the router is turned off.
| Parameter | Mode of operation via Router | Wi-Fi Direct mode |
|---|---|---|
| Internet access | An active router is required. | Not required |
| Communication range | Depends on the router (up to 30-50 m) | Limited (up to 10 m) |
| Number of users | Multi-user access | Usually 1 device |
| Print speed | High | Medium/High |
Please note that in Wi-Fi Direct mode, your phone may temporarily lose internet access, as the phone's Wi-Fi module switches to a direct connection with the printer. Some modern smartphones can handle two connections simultaneously, but this depends on the phone model.
Diagnostics and problem solving
Even if you follow the instructions exactly, technical difficulties can arise. Most often, users encounter a situation where the printer sees the network but won't connect, or the computer doesn't see the printer on the network. Printing should always be the first step in troubleshooting. network configuration report (Network Configuration Page). This will show your current IP address and connection status.
If the IP address starts with 0.0.0.0 or 169.254.x.x, which means the printer didn't receive an address from the router. This may indicate an encryption type incompatibility. Samsung SCX-3405W may not support the new WPA3 encryption standards, which are enabled by default on some modern routers. In your router settings, try switching the security mode to WPA2-PSK (AES).
Another common issue is a hidden SSID. If your network is hidden (not broadcasting its name), the printer won't be able to connect automatically. You'll have to manually enter the network name in the printer settings using the navigation buttons, which is extremely inconvenient. It's easier to temporarily enable the SSID broadcast in your router settings.
⚠️ Note: Router interfaces and printer firmware versions are subject to update. If the menu items described differ, please refer to the documentation for your specific equipment or the manufacturer's website for the latest security settings.
Also check if MAC address filtering is enabled on your router. If it is, you need to find the printer's MAC address (printed on the report or sticker on the back) and add it to the list of allowed devices in the router settings.
The printer prints, but with a delay.
If printing is very slow or has long pauses, the printer and router may be too far apart, or microwaves or other devices may be blocking the signal. Try changing the Wi-Fi channel in your router settings to 1, 6, or 11.
