Modern multifunctional devices The Epson L355 series has become a standard for home offices thanks to its cost-effectiveness and the convenience of wireless printing. However, even reliable equipment sometimes encounters software glitches, such as when the printer stops detecting the router or refuses to transmit data over the air. In such situations, the most effective solution is a complete reset of the network settings to factory defaults, which eliminates accumulated configuration errors.
The recovery process Epson L355 Requires careful attention, as the device doesn't have a full touchscreen for navigating the complex menu. All actions are performed using a combination of buttons on the control panel and an indicator light, the blinking of which serves as the primary means of communication with the user. Understanding the logic behind the indicators Wi-Fi And Network is critical to the successful completion of the procedure.
Before resorting to drastic measures, it's worth making sure the problem lies with the printer software itself, and not with a faulty router or computer. Often, simply rebooting the hardware is enough, but if that doesn't help, then reset network settings Resets the wireless module to its default state, deleting all saved passwords and IP addresses. This is especially important when changing providers, purchasing a new router, or changing your home network security key.
Diagnosing wireless connection problems
Before starting the reset process, it is necessary to clearly identify the symptoms of the malfunction. Wi-Fi indicator The control panel light may behave differently: it may be solid, blink rapidly, or be completely off. If the light is green but printing isn't occurring, the problem may lie with the computer's job queues, not the printer itself. However, if the light is blinking green and orange simultaneously, or is only orange, this is a clear sign that the connection to the access point has been lost.
Owners of the model Epson L355 We often encounter a situation where, after updating our PC's operating system or changing router settings (for example, switching to WPA3 security or changing the broadcast channel), our printer stops responding. In this case, the device may continue to emit a signal, but it won't establish a stable connection. Diagnostics It starts with checking the list of available networks on the device itself, although on the L355 this is difficult to do without a computer, so visual analysis of the indicators remains the main tool.
It's also worth paying attention to the distance between the router and the printer. If the device is in a weak signal area, it may constantly lose connection, which may be mistaken for a malfunction. Make sure there's enough space between MFP There are no thick concrete walls or strong sources of interference, such as microwave ovens, near the router. If the physical location is fine but there's no connection, it's time to clear the network settings memory.
Preparing for the factory reset procedure
The success of the operation depends directly on the proper preparation of the work site and the equipment itself. You won't need any special cables or software for the initial stage, but having your network's initial data on hand will be extremely helpful. After the reset, the printer will forget everything, including the network name (SSID) and password, so you'll have to re-enter them. It's recommended to write this information down in advance or keep it handy to avoid searching for the provider's receipt mid-process.
Make sure the printer is turned on and in Ready mode, not in deep sleep. If the device is asleep, press the power button to wake it, but do not turn it off completely during the setup process. It's also important to check the ink levels, as some models can lock out network functions when ink levels are critically low. While this is rare for the L355, it's still a good idea to check. Stable power supply — the key to success, power surges can interrupt the process of flashing network modules.
For convenience, you can prepare a computer or smartphone for subsequent setup. If you plan to use the WPS method, make sure your router has a physical WPS button or it's accessible through the web interface. If you're manually entering data via a PC, make sure the drivers are installed. Epson already installed or the installation disk/file is accessible. Preparation only takes a couple of minutes but saves a lot of hassle later.
Method 1: Reset via a combination of buttons on the panel
The fastest way to return network settings To reset the device to factory defaults, use a hidden combination of buttons on the front panel. This method doesn't require a computer and works even if the drivers aren't installed or a PC is unavailable. On this model Epson L355 This function is controlled by the "Network Status" button (often marked with a network icon or the letter "i" in a circle) in combination with the power button or the wireless button.
To perform a reset, find the button Network StatusPress and hold it for 5-7 seconds until the network and Wi-Fi indicators start flashing simultaneously. Some firmware versions may require you to hold both buttons simultaneously. Wi-Fi and buttons Network StatusThe exact sequence may vary slightly depending on the board revision, but the principle remains the same: holding the buttons for a long time initiates reset mode. Once the indicators begin flashing in a specific rhythm (the usual green and orange flashing), release the buttons.
After releasing the buttons, the printer will begin the network module initialization process. The Wi-Fi indicator should turn off and then turn solid green or start blinking slowly, waiting for a connection. This means settings memory The device has been successfully cleared, and is ready for reconfiguration. If the indicators remain orange or flash in alarm mode, you may need to repeat the procedure, ensuring you held the buttons down long enough.
Method 2: Reset via Epson Net Config utility
A more advanced and informative way to manage network parameters is to use specialized software. Epson Net ConfigThis utility not only allows you to reset the settings but also view detailed information about the current network status, IP address, MAC address, and encryption type. For this method to work, the printer must be temporarily connected to the computer via USB or be on the same network (if it's still responsive).
After installing the utility (it's often included with the drivers or available on the official website), launch the program and find your device in the list. Select the printer. Epson L355 and go to the configuration menu. There you'll find the "Initialize" or "Reset Network Settings" option. Pressing this button will send a command to the printer that will forcefully clear all user data in the network module. This is especially useful if the printer's control panel buttons are stuck or unresponsive.
The advantage of this method is that you see the results immediately and can reconfigure the settings immediately without switching between windows. The utility may also prompt you to update. firmware (firmware) of the network module, which often resolves compatibility issues with new routers. However, caution is advised: interrupting the firmware update process may render the network adapter inoperable.
What should I do if Epson Net Config doesn't see my printer?
If the utility doesn't detect the device, check that the scanner and printer drivers are fully installed. Sometimes the network component isn't installed during a custom installation. Also, try temporarily disabling Windows Firewall or antivirus software, as they may be blocking the utility's local network search. Make sure the computer and printer are on the same subnet (e.g., 192.168.1.X).
Setting up Wi-Fi Direct for printing without a router
After resetting the settings, you can use the mode Wi-Fi Direct, which allows you to print directly from your phone or tablet, bypassing your home router. This is an ideal solution for temporary printing or in offices where access to the main network is limited. In this mode, the printer itself becomes an access point, creating its own network to which your devices can connect.
To activate this mode on Epson L355 After the reset, press and hold the Wi-Fi button for about 3 seconds until the Wi-Fi and Wi-Fi Direct (smartphone icon) indicators start flashing. The printer will print a network information sheet, including the network name (SSID) and password. This information is unique to each device and is generated at the factory, so it cannot be changed manually. However, it can be found by printing a network status report.
By connecting to the printer's network from your smartphone, you can send documents to print via the app. Epson iPrintThis method is convenient because it operates autonomously, but it has a limitation: while the phone is connected to the printer, it may lose internet access if the smartphone only has one Wi-Fi module. Therefore, for continuous use, it's best to set up a connection through the main router.
☑️ Checklist before resetting settings
Reconnecting after a reset
When the settings are reset, the printer is in a "clean slate" state and awaits commands. The easiest way to restore communication is to use technology WPS (Wi-Fi Protected Setup), if your router supports it. Find the WPS button on the router (it's often hidden or requires a long press), press it, and then press the Wi-Fi button on the printer within 2 minutes. The devices will find each other and automatically exchange passwords.
If WPS doesn't work or isn't supported, you'll need to use the software method. Insert the installation disc or run the driver downloaded from the Epson website. During the installation, select the "Wireless Connection" option and follow the wizard's instructions. The program will automatically find the reset printer and transfer the new network settings to it. L355 It is also possible to use a temporary connection via a USB cable specifically for transferring Wi-Fi parameters, after which the cable can be disconnected.
Once successfully configured, the Wi-Fi indicator should be solid green. Print a connection report (usually by holding the network status button) to ensure the printer has received the correct connection. IP address From the router. If the report shows an address like 169.254.xx, this means the connection is not established and the printer has not received an address from the router's DHCP server. In this case, check the router's security settings.
| Indicator | State | Meaning | Action |
|---|---|---|---|
| Wi-Fi | It's green | There is a network connection | Print documents |
| Wi-Fi | Flashing green | Searching for a network/data transfer | Wait for completion |
| Wi-Fi | It's glowing orange | Connection error | Check password/settings |
| Wi-Fi + Network | Blink together | Reset mode / WPS | Release the buttons or press WPS |
Common mistakes and how to fix them
Even if you follow the instructions carefully, unexpected complications may arise. One of the most common issues is frequency band incompatibility. Printer Epson L355 works only in the range 2.4 GHzIf your router only distributes 5 GHz bands or combines them into a single network with 5 GHz as the priority, the printer may not see the network or constantly lose connection. You need to explicitly separate these bands in your router settings or enable compatibility mode.
Another common error is an incorrect password format. When entering the security key, make sure you're not case-sensitive (uppercase and lowercase letters matter) or adding extra spaces at the beginning or end of the line. Special characters in the password can also sometimes be incorrectly handled by older firmware, so if you encounter problems, try temporarily changing your router password to a simpler one (letters and numbers only), setting up a printer, and then resetting the password if the system allows.
Blocking by antivirus software or firewall software is another hidden enemy. During initial setup via a PC, security systems may detect attempts to write printer settings as suspicious activity. It's recommended to temporarily disable third-party antivirus software during setup. It's also worth checking that MAC address filtering isn't enabled on your router, which could block access for new devices.
⚠️ Attention: Do not attempt to reset the printer while printing or scanning. This may damage the mechanical component (carriage) or cause a software failure, requiring the device to be taken to a service center for firmware reflashing.
⚠️ Attention: Router interfaces and printer firmware versions are subject to update. If the menu items described here differ from what you see on the screen, please refer to the documentation for your specific device or the manufacturer's official website for the latest information.
Final operating recommendations
After successfully restoring your operation Epson MFP It's worth thinking about preventing similar problems in the future. Avoid changing router settings unnecessarily, especially those related to security and broadcast channels. If you must change your provider's equipment, prepare in advance to reconfigure all peripherals in your home, including printers, cameras, and smart plugs.
Update your printer software regularly. Epson periodically releases updates that improve compatibility with new Wi-Fi standards and fix known bugs. You can check for updates using the same Epson Software Updater utility. It only takes a few minutes, but it could save you hours of troubleshooting down the road.
Remember that the L355 series is designed for intensive use, and its network modules are quite reliable. Most issues can be resolved with a simple reboot or reset. Proper use of wireless printing capabilities will make your work more mobile and convenient, eliminating unnecessary cables and restrictions.
Is it possible to set up a printer without a computer?
Yes, for the Epson L355, this is possible via Wi-Fi Direct and the Epson iPrint app on your smartphone. However, initial network setup (entering the router password) via the phone screen can be inconvenient due to the lack of a keyboard on the printer itself. The easiest way is to use WPS or a one-time connection via USB.
What should I do if the Wi-Fi indicator remains orange after a reset?
An orange light means the printer can't connect to the network. Check that the network name (SSID) and password are entered correctly. Make sure the router is turned on and transmitting a 2.4 GHz signal. Also, check that the printer isn't too far from the router.
Will this procedure reset the scanner settings?
Resetting network settings only affects Wi-Fi connection settings and IP addressing. Scan settings, such as default resolution and file type, are saved in the device's memory. However, scan-to-PC paths may become lost if the printer's IP address changes and will need to be reconfigured in the software.
How to find out the printer's IP address after setup?
The easiest way is to print a network status report. To do this, press and hold the network status button (the "i" or network icon) on your printer for a few seconds until the printer starts printing. The current IP address will be listed in the TCP/IP section on the printed report.
Is it possible to reset the printer if it is not responding?
If the printer stops responding to buttons completely, try a cold reset: turn off the device, unplug the power cord for 1-2 minutes, then turn it back on. If this doesn't help, the problem may be hardware-related.
