Many wireless device users face a situation where they need to connect a new device to the same network as a printer, but they've forgotten the Wi-Fi password. Owners of devices in the Canon PIXMA People often wonder whether it's possible to retrieve saved data directly from a printer's memory. Unfortunately, the security architecture of most modern devices, including MFPs, doesn't allow for the stored encryption key to be easily viewed in plaintext via the standard on-screen menu.
However, this doesn't mean the situation is hopeless. There are several workarounds and technical solutions that can restore access or reconfigure the connection without losing functionality. Wireless network security The printer is designed to act more as a client than as a key-dealer, but we'll cover all the available diagnostic and reset methods to help you regain control.
In this article, we'll take a detailed look at why simply reading a password from the screen isn't possible and what alternatives are needed. We'll cover working with software, mobile apps, and physical buttons on the device. Understanding these processes will help you avoid wasted time and incorrect hardware interactions.
Why can't I just look at the password on the printer screen?
The first thing that the owner of the equipment needs to realize is CanonThis is how the WPA2 and WPA3 security protocols work. When connecting to a router, the printer uses a password for authentication, but doesn't store it in a user-readable text file. Network settings The device's memory is encrypted, and the display interface, if present, typically only displays the connection status (IP address, signal strength), but not the access key.
This isn't done out of malice on the part of the manufacturer, but to protect your local network. If anyone with physical access to the office printer could easily find out the Wi-Fi password, it would create a huge breach in corporate data security. Therefore, the menu Settings → Network Settings The MFP display most often only offers to change settings or disable Wi-Fi, but does not show the current key.
⚠️ Warning: Attempting to reflash the printer with third-party software to extract data may cause irreversible damage to the firmware and void the warranty. Use only Canon's proprietary methods.
There are rare exceptions for very old push-button models, where it was sometimes possible to display a network report, but even there, the password was often hidden behind asterisks. Therefore, the main focus should not be on "reading" the memory, but on restoring access to the router or using the function WPS to reconnect without entering a key.
Using Network Connection Reports
Although direct viewing of the password is not possible, many models Canon PIXMA (especially the G, TS, and MG series) can print detailed network status reports. These reports contain technical information that can be useful for diagnostics and, in some rare cases with older firmware, hints about the encryption type. To obtain such a report, you usually need to press a key combination.
On most models with a monochrome display, you need to press a button Setup (gear icon), then use the arrow keys to repeatedly select the device or settings item until you find the report print option. For models without a screen, holding down the button is often used. Wireless or a combination Stop + BlackIt is better to look for the exact combination in the manual of a specific model, since the logic Canon PIXMA may differ.
What to do if the report does not print?
If the error light is on when you try to print a report, check the paper and ink levels. Also, make sure the printer isn't in deep sleep mode—wake it up by pressing the power button.
In the printed report, look for the section Wireless LANIt will list the SSID (your network name), the printer's MAC address, and the IP address. If you're lucky and the model is very old, the key type may be listed, but the key itself will be hidden. However, knowing the printer's IP address can help you access its web interface, if this feature is supported, although this is only for home models. PIXMA This is a rarity.
- 🖨️ Press the "Settings" button or hold the "Stop" button until you hear a beep to start printing the report.
- 📄 Examine the “LAN Report” or “Wireless Report” section on the printed sheet.
- 🔍 Find the SSID line to make sure that the printer is connected to your network and not to a neighbor's.
- 📡 Check your signal strength to rule out issues with your router's range.
Restoring access via a PC already connected to Wi-Fi
The most reliable way to find out the password if the printer Canon If a printer is already successfully connected to the network, you can "ask" it from a computer that's also connected to the same Wi-Fi network. Windows stores the keys of all the networks it's ever connected to. This works because the OS manages network profiles, and the printer is simply one of the clients.
To do this, you need to open the command prompt. Click Win + R, enter cmd and press Enter. In the black console window, you need to enter the command to display all saved profiles. Find your network name (SSID) in the list. Then, use the command to display the key for a specific network. This is the standard procedure for Windows 10 and 11.
netsh wlan show profile name="Your_Network_Name" key=clearIn the command output, look for the line "Key Content." This will contain your password in clear text. This method works regardless of the printer model, whether it's Canon PIXMA TS3340 or old MG2540The main thing is that the computer remembers this network. If the computer is connected via cable but remembers the Wi-Fi profile, this method will also work.
Using the Canon PRINT Inkjet/SELPHY mobile app
Modern models Canon PIXMA actively interact with smartphones through the app Canon PRINT Inkjet/SELPHYIf your phone is already connected to Wi-Fi, the app can help you transfer network settings to the printer without having to re-enter the password on your phone's keypad or search for it in your notes. This is especially convenient for devices without a display.
The process is as follows: launch the app, select your printer, and go to Wi-Fi settings. The app will prompt you to "Reconfigure Wi-Fi" or "Change settings." At this point, your phone will transmit the current password for the network it's connected to directly to the printer via a secure channel (often using Bluetooth or a direct Wi-Fi connection). Transfer protocol data in this case is safe and does not require entering characters.
| Canon PIXMA model | Canon Print Support | Connection method | Peculiarities |
|---|---|---|---|
| G Series (G1411, G3411) | Yes | Wi-Fi / Direct | AP mode is required for initial setup. |
| TS Series (TS3340, TS5340) | Yes | Wi-Fi / Bluetooth | Automatic password transfer |
| MG Series (MG2540, MG3640) | Partially | Wi-Fi | May require a WPS button |
| TR Series (TR4540, TR8540) | Yes | Wi-Fi / Ethernet | Cloud functionality support |
If the printer was already connected to the network, but you changed the router, the app will allow you to quickly switch it to the new network. It's important to have location services and Bluetooth enabled on your smartphone, as Android And iOS These permissions are required to scan the environment and manipulate network configurations. This is a standard security requirement for mobile operating systems.
Resetting the network settings of a Canon PIXMA printer
If none of these methods work, or you've changed your ISP and password, there's a radical but effective solution: resetting the printer's network settings. This will reset the Wi-Fi module to its factory defaults, allowing you to reconnect it with the new password (or by setting it up again). Reset settings Does not affect print settings or ink counters, only network.
To reset models with a display, go to the menu, select "Device Settings," then "LAN Settings," and find the "Reset LAN Settings" option. On models without a display (e.g., PIXMA TS2040) often requires holding down the button Wireless until the power light flashes a certain number of times (usually 2 or 3 times), or use a combination Stop + Wireless.
☑️ Network reset algorithm
After the reset, the Wi-Fi indicator on the printer will begin flashing, indicating setup mode. At this point, the device creates its own network (Direct-Connection), which you can connect to from your phone or computer for initial configuration. This is standard behavior for Canon, which allows you to configure the device without a cable.
⚠️ Note: After resetting network settings, all computers in the house will lose connection to the printer. You will need to re-add the device to the system on each PC that needs to print.
Alternative methods: WPS and direct connection
If you don't know the password but have physical access to the router, the easiest way is to use technology WPS (Wi-Fi Protected Setup). It allows you to connect devices with the press of a button, bypassing the password entry. There's a WPS button on the router (sometimes combined with a Reset button, so be careful), and on the printer Canon - button Wireless or WPS menu.
The algorithm is simple: press the WPS button on the router, then within 2 minutes press the wireless button on the printer (or select WPS in the menu). The devices will exchange encryption keys automatically. This is the fastest method if the router is within range. For models without a screen, such as Canon PIXMA TS3340, a mode is often used where you need to press the Wi-Fi button and hold the button with the image of a straight line (or Stop) until the indicators flash.
Another option is to use a USB cable for initial setup. Even if the cable isn't included (for some models), you can purchase one separately. After connecting the printer to your PC via USB, run the installation software from the Canon website. The software will automatically retrieve the Wi-Fi settings from your computer and transfer them to the printer. This acts as a "bridge," transferring the password from your PC's memory to the MFP's.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password just by looking at the sticker under the printer?
No, on the sticker under the body Canon PIXMA Typically, the serial number, model, and MAC address are listed. Your home network password isn't listed there, as this is user-specific, not factory-set. It may only list the password for "Direct Connection" mode (direct connection to the printer) if that's the default setting, but it's not your internet password.
What should I do if the WPS button on my router doesn't work?
If the button is physically missing or unresponsive, use the USB cable connection method (as described in the alternative methods section) or reset the network settings on the printer and set it up again using the mobile app. Canon PRINT, which can read the password from the smartphone system.
Will a Factory Reset reset the printer's ink counters?
A full reset of the device (all settings) may affect some system parameters, but typically doesn't reset the absorber pad or ink counters immediately. However, resetting the LAN (network) settings is completely safe for the printer's mechanics and cartridges. It's recommended to do just that. reset LAN settings, and not a full system reset if the problem is only with Wi-Fi.
Why can't my printer see my 5GHz network?
Many models Canon PIXMA (especially the budget TS and MG series) only support the 2.4 GHz band. If your router only distributes 5 GHz or combines them into a single network with 5 GHz priority, the printer may not detect the signal. Try separating the networks in your router settings or enabling compatibility.
How do I connect a printer if I changed my router and don't remember the old password?
You don't need the old password. You need to reset the printer's network settings (as described above) so it "forgets" the old router. Then connect it to the new router, entering the current password for the new network via a PC or app. The printer doesn't store passwords in plaintext, so it won't be able to "remember" the old one.
