Canon printers are one of the most recommended brands for their high-quality and reliable performance. However, like any other machines, they may sometimes encounter some errors that can affect their functionality. One of these errors is the Canon printer error code E31, which means that there is a problem with the network communication or the print server. This error can prevent you from printing or scanning documents from your printer. In this blog, I will tell you what causes the Canon printer error code E31 and how to fix it.

What Causes the Canon Printer Error Code E31?

The Canon printer error code E31 can be caused by various factors, such as:

• A faulty network cable or router
• A wrong network configuration or IP address
• A firewall or antivirus software blocking the network connection
• A corrupted or outdated printer driver
• A malfunctioning print server or network device

These factors can interfere with the connection between your printer and your computer or mobile device, and cause the error code E31 to appear on your printer’s display.

How to Fix the Canon Printer Error Code E31?

To fix the Canon printer error code E31, you need to check and fix the following aspects:

• The network connection and settings
• The printer driver and software
• The print server and network device

Check and Fix the Network Connection and Settings

The first thing you need to do is to check and fix the network connection and settings of your printer and your computer or mobile device. Make sure that:

• The network cable or router is working properly and securely connected
• The printer and computer or mobile device are on the same network and have valid IP addresses
• The network settings of the printer match the settings of the computer or mobile device and router
• The firewall or antivirus software is not blocking the network connection

To check and fix the network connection and settings, you can follow these steps:

1. Press the Menu button on your printer and select Network Settings.
2. Select TCP/IP Settings and then IPv4.
3. Check the IP address, subnet mask, gateway, and DNS server of your printer. If they are set to Auto, you can change them to Manual and enter the correct values according to your network configuration.
4. Press the OK button to save the changes.
5. On your computer or mobile device, open a web browser and type the IP address of your printer in the address bar. If you can access the printer’s web page, it means that the network connection is good. If not, you may need to reset the network settings of your printer by following these steps:
   • Press the Menu button on your printer and select Network Settings.
   • Select Reset Network Settings and then Yes.
   • Wait for the printer to restart and then reconnect it to your network.
6. If you still cannot access the printer’s web page, you may need to check your router’s settings and make sure that it is not blocking the printer’s IP address or port.

Update the Printer Driver and Software

The next thing you need to do is to update the printer driver and software on your computer or mobile device. A corrupted or outdated printer driver can cause various errors, including the error code E31. To update the printer driver and software, you can follow these steps:

1.  enter your printer model in the search box.
2. Select your operating system and download the latest driver and software for your printer.
3. Run the downloaded file and follow the on-screen instructions to install them on your computer or mobile device.
4. Restart your computer or mobile device and try to print again.

Check and Fix the Print Server and Network Device

The last thing you need to do is to check and fix the print server and network device that are connected to your printer. A print server is a device that allows multiple computers to share a printer over a network. A network device is a device that connects your printer to a network, such as a router or a switch. If there is a problem with these devices, they can cause the error code E31. To check and fix them, you can follow these steps:

1. Make sure that the print server and network device are working properly and securely connected to your printer and network.
2. Check the settings of the print server and network device and make sure that they are compatible with your printer and network.
3. Update the firmware of the print server and network device if needed.
4. Restart the print server and network device and try to print again.

Conclusion

The Canon printer error code E31 can be annoying, but it can be fixed easily by following these steps:

• Check and fix the network connection and settings
• Update the printer driver and software
