Owners of office equipment often face the need to get rid of unnecessary wires, and the model Samsung SCX-3405W Enables wireless printing without loss of functionality. Connecting this multifunctional device to a local network allows scanning and printing from any computer or mobile device within range. The setup process may seem complicated at first glance, but following the steps carefully ensures stable operation.
The main difficulty lies in choosing the right connection method, as the manufacturer provides several network integration options. You will have to choose between a direct connection via Wi-Fi Direct or a classic connection via a wireless router. Both methods have their advantages, but require different approaches to software installation and security configuration.
In this article, we'll cover each setup step in detail, focusing on the nuances of working with drivers and static IP addresses. Understanding the network protocol's operating principles will help you avoid common mistakes, such as the system losing the printer after rebooting the router. Let's get started preparing your equipment for wireless operation.
Preparatory stage and compatibility check
Before proceeding with software setup, you need to ensure that your hardware is physically ready. Make sure your router is working properly and transmitting a signal in the 2.4 GHz range, as older printer models, including the 2.4 GHz series, may not be able to do so. SCX-3400, often don't support modern 5 GHz standards. This is critical, as attempting to connect to a 5 GHz network will result in the device simply not seeing your access point.
You will also need to download the latest version of the drivers from the official support website in advance. Using the included discs may be ineffective, as the software on them is often outdated. Download the package. Unified Driver, which contains all the necessary components for printing, scanning and managing the device.
⚠️ Note: Router web configurator interfaces and driver versions may be updated by the manufacturer. If a step in the instructions visually differs from what you see on the screen, look for similar items in your equipment's settings menu.
To ensure a successful installation, we recommend temporarily disabling any firewall or antivirus software that may be blocking network device detection. After setup is complete, you can restore your security settings to their default state. Preparing your cables is also important: although we're setting up Wi-Fi, the initial synchronization may require a brief USB connection.
Connection method via WPS (Wi-Fi Protected Setup)
The fastest way to integrate Samsung SCX-3405W The easiest way to connect to a network is to use WPS technology if your router supports it. This method eliminates the need to manually enter a password and complex IP address settings. Simply press the corresponding button on the router, then activate WPS mode on the printer's control panel.
The process is as follows: On the printer, press the button WPS (or the button combination specified in the instructions, often a few seconds of holding the Wi-Fi button). The wireless network indicator will begin flashing, indicating it's searching for an access point. Within two minutes, press the WPS button on your router.
If the connection is successful, the Wi-Fi indicator on the device will stop flashing and remain solid. This means the printer has automatically acquired an IP address and is ready to use. However, if automatic setup fails, you'll need to use the manual method using the software.
Setting up via Samsung software
If automatic methods don't work, the most reliable option is to use the driver installation package. Run the previously downloaded installation file and follow the wizard's instructions. When prompted to choose a connection type, select Wireless network connectionThe program will offer several scenarios; select the one that suits your situation.
During the installation process, you will be prompted to select your printer from a list of found devices. If the device is not found, the system may prompt you to temporarily connect it via USB cable to transfer network settings. This is standard practice for models in the series. 3405After transferring the Wi-Fi parameters, the cable can be disconnected.
The key here is to select the correct SSID (your network name) from the drop-down list. Make sure you select your home or office network, not your neighbor's. Enter the Wi-Fi password in the appropriate field, being careful to ensure the letters are case-sensitive.
☑️ Checklist before installing drivers
After installing the drivers, we recommend printing a test configuration page. This will ensure a stable connection between the computer and the printer. The configuration report will show the device's exact IP address, which will be useful for further diagnostics.
Using Wi-Fi Direct technology
Technology Wi-Fi Direct Allows you to connect mobile devices directly to the printer without an intermediate router. This is ideal for quickly printing photos from your smartphone or documents from your tablet when you're away from the office or home network. In this mode, the printer itself becomes an access point.
To activate this mode, press and hold the Wi-Fi Direct button on the printer control panel. The network name (usually starting with Direct-XX-SCX-3405) and a password to connect. The standard password is often sec00000, but it is better to check it in the report printing menu.
On your smartphone or laptop, find the new network in the list of available Wi-Fi connections and enter the password. Once connected, you can print documents using the standard operating system menus or mobile apps. In this mode, the device may not have internet access, as the network channel is busy transmitting data to the printer.
⚠️ Please note: When connecting via Wi-Fi Direct, data transfer speeds may be lower than via a dedicated router. For printing large documents (over 50 pages), we recommend using a standard network connection.
Network troubleshooting and diagnostics
Even with proper configuration, situations may arise where the computer stops seeing the printer. This is most often due to a change in the device's IP address if a static address isn't reserved in the router. Dynamic address distribution (DHCP) can assign a new address to the printer after a router reboot, causing the driver to lose connection with the device.
To solve this problem, you need to go to the router settings and find the section DHCP Server or Address ReservationFind your device in the list by its MAC address (found on the sticker on the back of the printer) and assign it a permanent IP address. This will ensure that the address 192.168.0.x will always belong to your MFP.
Another common issue is incompatibility of security protocols. If your router is configured to use only WPA3, the old printer may not connect. In this case, you need to set the router to mixed mode. WPA/WPA2.
What to do if the red Wi-Fi light is on?
A red light usually indicates a critical connection error. Try completely resetting the printer's network settings (by holding the Wi-Fi button for more than 10 seconds), then repeat the pairing process. Also, check if your router is using MAC address filtering.
If all else fails, reset the printer's network settings to factory defaults. This can be done through the menu or by pressing a key combination. After the reset, the device will return to its out-of-the-box state and will require reconfiguration via USB or WPS.
Comparison of connection methods
The choice of connection method depends on your specific needs and network configuration. For office use, where access to the printer from multiple computers simultaneously is essential, a router connection is the only suitable option. For home printing from one or two devices, Wi-Fi Direct is perfectly sufficient.
Below is a table comparing the main characteristics of the different connection methods of the model. Samsung SCX-3405W:
| Parameter | Via Router | Wi-Fi Direct | USB cable |
|---|---|---|---|
| Range of action | Up to 30 meters (indoors) | Up to 10 meters | Up to 2 meters |
| Number of users | Unlimited | One active | One PC |
| Internet access | Eat | No (usually) | Eat |
| Difficulty of setup | Average | Low | Low |
Based on this information, you can choose the best option for your situation. Don't forget that hybrid use is also possible: you can keep the printer connected to the router for your PC and periodically connect via Direct from your smartphone.
