Experiencing the frustrating “Could not connect. Check the PSK settings” error on your Canon printer? You’re not alone. This message typically pops up when your printer is struggling to connect to your Wi-Fi network, and it can halt your printing tasks unexpectedly. Before you assume your printer is faulty, let’s explore what this error means and how you can effectively troubleshoot it to get back to seamless wireless printing.
Understanding the “Check PSK Settings” Error
The “PSK” in the error message stands for “Pre-Shared Key,” which is essentially your Wi-Fi password. Therefore, “Check PSK settings” directly points to a potential issue with the password your printer is using to connect to your wireless network. While the error message itself suggests a password problem, the root cause might be slightly more nuanced. Here’s a breakdown of common reasons behind this error:
- Incorrect Wi-Fi Password: This is the most straightforward reason. Even a minor typo in your password during the initial printer setup or a subsequent reconnection can trigger this error. Remember that Wi-Fi passwords are case-sensitive.
- Network Changes: If you’ve recently changed your Wi-Fi password, router, or network settings, your printer, still holding onto the old credentials, will fail to connect and display this error.
- Weak Wi-Fi Signal: A weak or unstable Wi-Fi signal can sometimes disrupt the printer’s ability to authenticate and connect, leading to a PSK error, even if the password is correct.
- Printer Network Configuration Issues: Occasionally, the printer’s network settings might become corrupted or require a refresh, causing connection problems.
- Router Problems: Issues with your router, such as needing a restart or firmware update, can also indirectly cause your printer to display this error.
Troubleshooting Steps to Resolve “Check PSK Settings”
Let’s walk through a series of troubleshooting steps to help you resolve this error and get your Canon printer back online.
1. Double-Check and Re-enter Your Wi-Fi Password
The first and most crucial step is to meticulously verify your Wi-Fi password.
- Locate your Wi-Fi password: This is usually found on your router itself (often on a sticker) or in your router’s configuration settings (accessed through a web browser).
- Access your printer’s wireless settings: Navigate to the “Wireless LAN setup” or “Network settings” menu on your Canon printer’s control panel. The exact menu names may vary slightly depending on your printer model, but they are usually found under “Setup” or “Settings.”
- Re-enter your password: Carefully retype your Wi-Fi password, paying close attention to capitalization and special characters. It’s helpful to have the password displayed on another device (like your phone or computer) to minimize errors while entering it on the printer’s smaller screen.

2. Restart Your Printer and Router
A simple restart of both your printer and your Wi-Fi router can often resolve temporary glitches that might be causing the connection issue.
- Restart your router: Unplug your Wi-Fi router from the power outlet, wait for about 30 seconds, and then plug it back in. Allow a few minutes for the router to fully restart and reconnect to the internet.
- Restart your Canon printer: Turn off your printer, wait for about a minute, and then turn it back on.
After both devices have restarted, try reconnecting your printer to your Wi-Fi network through the printer’s control panel.

3. Ensure Strong Wi-Fi Signal Strength
A weak Wi-Fi signal can be a hidden culprit.
- Check signal strength: Most printers display Wi-Fi signal strength in their network settings menu. Ideally, you want a strong or good signal.
- Move closer to the router: If the signal is weak, try moving your printer closer to your Wi-Fi router to improve signal strength and stability.
- Eliminate interference: Physical obstructions like walls, metal objects, and interference from other electronic devices can weaken Wi-Fi signals. Try to minimize these factors.
4. Reconfigure Wireless Settings on Your Printer
If restarting and password re-entry don’t work, try completely reconfiguring the wireless settings on your Canon printer.
- Forget network (if option available): Some printers offer an option to “forget network” or “delete wireless settings.” If available, use this option to clear the existing wireless configuration.
- Redo wireless setup: Go through the wireless setup process again from scratch, as if you are setting up the printer for the first time. This ensures a fresh connection attempt.

5. Consider a Wired USB Connection (Temporary Solution)
As a temporary workaround or to isolate if the issue is truly wireless-related, try connecting your printer to your computer using a USB cable.
- Connect USB cable: Use a USB-B to USB-A cable (standard printer USB cable) to connect your printer directly to your computer.
- Select USB connection on printer: In your printer’s settings, choose “USB” or “Wired LAN” as the connection method.
- Install drivers (if needed): Your computer should automatically detect the printer. If prompted, install the necessary printer drivers.
If printing works correctly via USB, this suggests the problem likely lies within the wireless connection itself, further pointing towards the PSK settings or network issues.
6. Factory Reset (Use with Caution)
As a last resort, you can perform a factory reset on your Canon printer. Be aware that this will erase all settings, including network settings, and revert the printer to its original factory state. You will need to set up everything again from scratch.
- Consult your printer manual: The process for factory resetting varies between Canon printer models. Refer to your printer’s manual for specific instructions on how to perform a factory reset. This usually involves pressing and holding a combination of buttons on the printer’s control panel.
Important Note: Only use factory reset if other troubleshooting steps have failed, as it is a more drastic measure.
When to Seek Professional Support
If you’ve exhausted all these troubleshooting steps and are still facing the “Check PSK settings” error, it might be time to consider professional help.
- Canon Support: Contact Canon’s customer support. They can provide model-specific guidance and potentially diagnose hardware issues.
- Technical Expert: If you suspect a more complex network problem or printer hardware failure, consulting a qualified technical expert or printer repair service might be necessary.
By systematically following these steps, you should be able to identify and resolve the “Check PSK settings” error on your Canon printer and restore your wireless printing functionality. Remember to double-check every step and proceed methodically for the best results.
