Resetting the Wi‑Fi Connection on a Canon Pixma TR4520

Introduction

A wireless connection that keeps dropping, a printer that refuses to find your network, or an error message that says “Unable to connect” can be frustrating, especially when you need a document printed urgently. The Canon Pixma TR4520, like many home‑office printers, relies on a stable Wi‑Fi link to communicate with your computer or mobile device. When connectivity issues arise, a quick reset of the Wi‑Fi settings often resolves the problem.

This guide explains why a reset might be necessary, how to prepare the printer and network, the exact steps to reset the Wi‑Fi connection on the Canon Pixma TR4520, how to reconnect the device, and what to do if the problem persists. Follow each section carefully and you’ll have your printer back online in no time.

Why Reset the Wi‑Fi Connection?

The Wi‑Fi reset function rewrites the wireless settings stored in the printer’s memory. Over time, firmware updates, network changes, or corrupted settings can cause the printer to hold outdated or incorrect information. A reset forces the printer to start fresh, clearing any old network data and eliminating misconfigurations that prevent a successful connection.

Common symptoms that indicate a reset may help:

• The printer shows “WLAN Connect” repeatedly on the LCD.
• The network icon flashes but the printer does not appear in the list of available devices.
• Printing from a mobile app yields “Connection failed”.
• The printer’s wireless indicator stays on “Off” even after enabling Wi‑Fi on the device.

Preparation Checklist

Before you begin, ensure that the following items are ready:

Tip: It is best to perform the reset on the day you have access to both the printer and a device capable of configuring it. If you prefer to avoid a full reset, you can try using the built‑in “Network Status” screen to locate the printer on your network and manually enter the SSID and password.

Step 1: Turn on the Printer and Check the Display

1. Power on the Pixma TR4520 by pressing the power button.
2. Watch the LCD screen for the message “Ready” or a Wi‑Fi symbol.
3. If the Wi‑Fi indicator shows a red “X” or the message “WLAN Connect,” the printer is not currently connected.

If the screen displays a normal “Ready” state but the printer is still offline, proceed to the next section.

Step 2: Access the Wireless Settings Menu

1. On the LCD, press the “Setup” button (usually represented by a wrench icon).
2. Navigate to the “Network” menu.
3. Select “Wireless LAN Settings”.
4. The screen will display the current SSID and the wireless status. If the SSID is blank or wrong, a reset will be required.

If you can’t see the menu options, the printer may already be in a locked state. In that case, move to the reset procedure.

Step 3: Reset the Wireless Connection

The Canon Pixma TR4520 offers a simple on‑screen reset option. Follow these instructions:

1. Inside the Wireless LAN Settings menu, choose “Reset Settings”.
2. The screen will prompt you to confirm. Select “Yes”.
3. The printer will clear all stored wireless credentials and reboot automatically.
4. When the LCD returns to the “Ready” screen, the wireless network indicator will turn off.

If the reset option is not visible (for example, if the printer’s firmware is outdated), you can perform a manual reset by turning the printer off, unplugging it for 30 seconds, then plugging it back in and powering on again. The printer will then reboot with default settings.

Step 4: Re‑Enter Your Wi‑Fi Network Information

After the reset, you must reconnect the printer to your network:

1. From the Wireless LAN Settings menu, select “Wireless LAN Settings” again.
2. Choose “Wireless LAN Settings” and then “Wireless LAN Settings” a second time if prompted.
3. The printer will start searching for available networks.
4. When your network name (SSID) appears on the screen, highlight it and press the “Select” button.
5. Enter the Wi‑Fi password using the on‑screen keypad.
6. Press “OK” to confirm.
7. The printer will attempt to connect. A successful connection is indicated by a green Wi‑Fi icon and a “Ready” message on the LCD.

If the printer shows “WLAN Connect” again after entering the password, double‑check that you typed the password correctly and that it matches the case‑sensitivity rules of your router.

Step 5: Verify the Connection

Once the printer claims it is connected, verify that it appears on your network:

Using a Computer

• Open a web browser and type http://192.168.1.1 (or the IP address assigned by your router) to access the router’s admin page.
• Look for the printer in the list of connected devices.
• You can also run the Canon IJ Network Utility on Windows or macOS to scan for the TR4520.

Using a Mobile Device

• Open the Canon PRINT app or any compatible printing app.
• The app should detect the Pixma TR4520 automatically.
• Try printing a test page from the app.

If the printer does not appear, check the router’s client list again or try moving the printer closer to the router to improve signal strength.

Troubleshooting Common Issues

Additional Tips for a Stable Connection

• Keep the firmware up to date: Firmware updates can fix bugs related to wireless connectivity. Use the Canon IJ Network Utility or download the latest firmware from Canon’s support site.
• Use a 2.4 GHz band: The Pixma TR4520 is optimized for 2.4 GHz networks. If you have a dual‑band router, disable the 5 GHz band for the printer or set the printer to use only the 2.4 GHz SSID.
• Assign a static IP: This prevents the router from changing the printer’s IP address, which can disrupt printing sessions.
• Avoid IP address conflicts: Make sure no other device uses the same IP as the printer.
• Use WPA2‑PSK security: This is the most compatible encryption for home printers.

FAQ

Q: Can I reset the Wi‑Fi connection without accessing the LCD?
A: Not directly. The printer’s internal reset requires interaction with the LCD or a power cycle. However, some routers allow you to delete a device from the client list, forcing the printer to reconnect.

Q: What if my router uses a hidden SSID?
A: The printer will not automatically detect a hidden network. You must manually enter the SSID and password through the printer’s “Wireless LAN Settings” menu.

Q: The printer connects but I cannot print from my phone.
A: Ensure that the Canon PRINT app is installed and that your phone is on the same Wi‑Fi network. Also, check that the printer’s firewall settings on the router allow local traffic.

Q: How often should I perform a Wi‑Fi reset?
A: Only when you experience connectivity problems. A reset deletes all saved networks, so you must reconnect each time. It is not a routine maintenance task.

Conclusion

Resetting the Wi‑Fi connection on the Canon Pixma TR4520 is a straightforward process that can quickly resolve many common networking issues. By following the step‑by‑step instructions above, you ensure that the printer starts with fresh wireless settings, accurately reflects your current network credentials, and maintains a reliable connection. Regular firmware updates, a stable 2.4 GHz signal, and a static IP address can further improve stability and keep your home office running smoothly. If problems persist after a reset and troubleshooting, consult Canon’s support resources or consider contacting your network administrator for advanced diagnostics.
