It's quite common to need to connect a device to a wireless network but lose or forget the password. Owners of popular inkjet MFPs Epson L3150 are no exception, especially considering that this model doesn't have a built-in screen to display system information. Users often look for a way to "find out" the current password, assuming it's stored somewhere in the device's memory. However, the architecture of Wi-Fi routers and printers is different: the printer acts as a network client and doesn't store the password in plain text for viewing.
Instead of searching for a forgotten code, the owner will need to reset the network settings or use alternative connection methods, such as WPS or a mobile app. This is a standard security procedure that doesn't require advanced technical knowledge. Restoring access Accessing Wi-Fi settings will only take a few minutes if you follow the steps in sequence using the buttons on the device body.
In this guide, we'll cover all possible scenarios: from a standard reset to using the Direct function. You'll learn how to correctly interpret blinking indicators and avoid common setup mistakes. Remember that for successful configuration, you'll always need to know the password for your home Wi-Fi network (router), as you'll need to re-enter it into the printer.
Why can't I just view my saved password?
Many users mistakenly believe that they can print the saved password or see it in the menu, as is sometimes the case with ink status reports. However, WPA2 security protocol, which is used in most modern networks, prevents client devices (printers, phones, laptops) from displaying or transmitting the password in clear text after a successful connection. This is a fundamental protection against data leakage.
MFP Epson L3150 The device features a minimalist interface consisting of just two buttons and a few indicators. The physical lack of a display makes it impossible to navigate complex menus to view system logs or network settings. The device stores the encryption key in internal memory solely for automatic connection to the router, but does not allow the user to read this string of characters.
⚠️ Attention: There's no hidden key combination or secret menu that would print a receipt with the current Wi-Fi router password stored in the printer's memory. Attempts to find such codes online often result in a factory reset, which, incidentally, is the solution.
The only legitimate way to "find out" what password a printer uses is to look at the settings of the router it's connected to. If the router has also been reset or the password is unknown, then the only solution is... reinitialize the networkThis is a safe process that will return the printer's network module to a state ready for a new configuration.
Resetting the Epson L3150 network settings to factory defaults
The most reliable way to restore control of your network connection is to reset the Wi-Fi settings. This procedure doesn't affect print settings, ink counters, or printhead calibration; it only clears the list of saved networks and passwords. First, make sure the device is turned on and idle (not printing or making any sounds).
On the control panel Epson L3150 There are two main buttons: the Power button and the Wireless button, marked with an antenna icon. We'll need the second one. Press and hold the button. Wireless within 5-7 seconds. The indicators will begin flashing, signaling the transition to configuration mode.
☑️ Network reset algorithm
The critical moment comes when the indicators Wi-Fi And Wi-Fi Direct (usually two adjacent LEDs) begin to flash simultaneously and rapidly. Once you see this rhythmic light, you can release the button. This means the indoor module has reset its old settings and is now awaiting a new connection command.
After resetting, the printer may automatically switch to Access Point mode, creating its own network with a name like EPSONXXXXXXThis is normal behavior. If you plan to connect the device via a computer, it's best to immediately launch the driver installation wizard, which will pick up the "ready for configuration" status.
Using WPS technology for quick connection
If your router supports the technology WPS (Wi-Fi Protected Setup), then the question of "how to find out the password" disappears. This standard allows devices to exchange encryption keys automatically with the physical press of a button. This is the simplest method for models without a screen, such as L3150.
Find the button marked on the body of your router. WPSIt can be a separate button or combined with the Wi-Fi power button. On the printer, press and hold the wireless network button until the network indicator starts blinking (usually about 3 seconds). Immediately after, press the WPS button on the router.
The devices will begin searching for each other. Within 2-3 minutes, the Wi-Fi indicator on the printer should turn solid green, indicating a successful connection. If the indicator flashes red or green at long intervals, the connection has not been established, and you should repeat the button procedure closer to the router.
What to do if WPS doesn't work?
The WPS feature may be disabled in your router settings for security reasons or may not be supported by your ISP. In this case, use the USB cable setup method or the Epson iPrint mobile app, which allows you to manually enter the password from your smartphone's screen.
Setup via PC and Epson Software Updater utility
For Windows or macOS users, the most controlled method is to use the official software. Utility Epson Software Updater Or the driver installation package allows you to transfer the Wi-Fi password to the printer via a temporary USB connection. You'll need a cable. USB Type-B, which often comes included.
Connect the printer to your computer using a cable and run the setup program. Select "Wireless Setup." The program will prompt you to select your network from a list of available networks. You will need to enter the Wi-Fi password in the appropriate field on the computer screen. Once entered, the program will transfer this information to the printer.
During the setup process, the program may prompt you to disconnect the USB cable at a certain point. Follow the on-screen instructions. Once complete, the printer will remember the network and connect to it automatically every time it's turned on until you change the router or password again.
| Indicator | State | Meaning | Action |
|---|---|---|---|
| Wi-Fi | Turned off | The network is disconnected | Press the Wireless button |
| Wi-Fi | Flashing green | Connection/data transfer in progress | Wait for completion |
| Wi-Fi | It's green | Connected to the network | You can print |
| Wi-Fi Direct | Flashing | Direct communication mode | Connect to the printer network |
Connecting via Epson iPrint and Direct mode
Modern smartphones allow you to set up a printer without using a computer. The app Epson iPrint (available for iOS and Android) can detect printers even if they are not connected to the main network, but are operating in the mode Wi-Fi DirectIn this mode, the printer itself creates a network to which you connect using your phone.
To activate this mode, press and hold the wireless button on the printer until the lights begin to blink alternately or light up in a specific pattern (consult the manual for specific blink patterns, usually alternating green lights). A network named EPSON-Printer-XXXX.
Once connected to this network, open the Epson iPrint app. It will automatically detect the device and offer to "Set up a wireless connection." You'll be prompted to select your home router from the list and enter the password. After this, the printer will switch from Direct mode to your primary network.
⚠️ Attention: When using Wi-Fi Direct, make sure your mobile data connection (3G/4G/5G) is disabled during setup. Otherwise, your phone may attempt to connect to the internet via cellular data without detecting the printer, and the setup process will be interrupted.
Access Point Mode (AP Mode) and its features
It's worth mentioning separately the mode in which the printer operates as an access point. This is often confused with a regular connection. In this mode AP Mode You don't enter your router password into the printer. Instead, you connect your phone or laptop to the Wi-Fi network provided by the printer itself.
This is convenient for printing documents from a phone when visiting or in an office where connecting other devices to the main network is not allowed. However, for regular home use, it's better to use the standard infrastructure (client) mode described above, as in access point mode, the printer won't have internet access for cloud functions.
Switching between modes often requires a specific sequence of presses. For example, holding the Wi-Fi button for more than 10 seconds can change the operating mode. The exact combination for L3350/L3150 It's better to check the manual, as firmware may differ.
Common problems when setting up a Wi-Fi module
Even knowing how to reset the settings, users still encounter difficulties. Often, the problem lies in the frequency range. Printers of the series L3150, like many budget IoT devices, only operate in the range 2.4 GHzIf your router only broadcasts 5 GHz or the network names are the same, the printer may not see them.
Another common mistake is using special characters in a password. While modern devices support complex passwords, some older printer firmware may not correctly handle characters like &, % or spaces. If the connection fails, try temporarily simplifying the router password to only letters and numbers.
It's also worth checking the MAC address filter on your router. If you have a whitelist configured, a new (or reset) printer won't be able to access the network until you add its MAC address to the router settings. You can find the address on the sticker on the back of the device or print a status report.
Is it possible to recover my password if I didn't write it down anywhere?
No, the printer itself doesn't remember the password in a readable form. You'll have to reset the router (if the password is forgotten there) or look for a sticker on the router itself, which often contains the factory password.
The Wi-Fi indicator is orange, what should I do?
An orange (or intermittently blinking green) light usually means the signal is too weak. Move the printer closer to the router or remove any physical obstacles between them.
Reset the settings, but the computer doesn’t see the printer?
After the reset, you'll need to re-start the printer addition process in the system (Windows/macOS). The old device will be listed as "Offline." You'll need to remove it and find a new one.
Does Wi-Fi Direct work without internet?
Yes, Direct Print mode works offline. You can print photos from your phone even if the printer doesn't have internet access, as long as you're connected to the printer's Wi-Fi network.
