Identifying the potential cause is the first step towards resolving the issue.
Basic Troubleshooting Steps
Let’s start with some simple checks and fixes that often resolve the “printer offline” problem.
Power Cycle Your Printer and Computer
This is often the first and easiest solution. Simply turning off both your printer and your computer, waiting a few seconds, and then turning them back on can often resolve temporary glitches.
- Turn off your Canon printer.
- Turn off your computer.
- Unplug both devices from the power outlet.
- Wait for at least 30 seconds.
- Plug the printer back in and turn it on.
- Plug the computer back in and turn it on.
- Check if the printer is now online.
Power cycling allows the devices to reset their connections and clear any temporary errors.
Check the Physical Connections
Ensure that all cables are securely connected. If you’re using a USB connection, try a different USB port on your computer. If you’re using a network connection (wired or wireless), verify that the network cable is properly plugged into both the printer and the router/switch or that the wireless connection is stable.
A loose or faulty cable can easily disrupt the communication between your computer and printer.
Verify the Printer Status
Check the printer’s control panel for any error messages or indicators. Make sure the printer is not paused, in sleep mode, or displaying any error codes. Sometimes, a simple paper jam or low ink level can cause the printer to go offline.
Consult your printer’s manual for specific instructions on interpreting error messages.
Advanced Troubleshooting for Network Printers
If the basic steps didn’t work, the problem might be related to your network connection.
Confirm Network Connectivity
Ensure that both your computer and printer are connected to the same network. Verify that your Wi-Fi is working correctly and that you have a stable internet connection. You can try accessing a website on your computer to confirm internet connectivity.
Sometimes, a simple network outage can be the culprit.
Check the Printer’s IP Address
Your printer needs a valid IP address to communicate on the network. You can usually find the printer’s IP address in the printer’s network settings menu (refer to your printer’s manual for instructions on how to access this menu).
On your computer, you can ping the printer’s IP address to check if it’s reachable. Open the Command Prompt (Windows) or Terminal (macOS) and type ping [printer's IP address] (e.g., ping 192.168.1.100). If you get replies, it means your computer can communicate with the printer. If you get “Request timed out” or similar errors, there’s a network connectivity issue.
If the printer doesn’t have an IP address, or the IP address is invalid, you may need to configure the network settings manually.
Reinstall the Printer Driver
A corrupted or outdated printer driver can often cause the “printer offline” issue. Reinstalling the driver can resolve these problems.
- Uninstall the current driver: Go to Control Panel (Windows) or System Preferences (macOS), find your printer in the “Devices and Printers” or “Printers & Scanners” section, and remove it.
- Download the latest driver: Visit the Canon website, find the driver download page for your specific printer model, and download the latest driver.
- Install the new driver: Run the downloaded driver installation file and follow the on-screen instructions.
Make sure to download the driver that is compatible with your operating system (Windows or macOS) and its version (e.g., Windows 10 64-bit).
Update the Printer Firmware
Printer firmware is the software embedded in the printer itself. Keeping it up-to-date can improve performance and fix bugs. Check the Canon website for firmware updates for your printer model.
Follow the instructions provided by Canon for updating the firmware. This usually involves downloading a firmware update file and running it on your computer while the printer is connected.
Troubleshooting USB Connections
If you are using a USB connection, there are specific troubleshooting steps you can follow.
Try a Different USB Port and Cable
A faulty USB port or cable can cause connectivity issues. Try connecting the printer to a different USB port on your computer. If possible, try using a different USB cable to rule out a cable problem.
Sometimes, the USB port on the back of the computer works better than the ones on the front.
Check Device Manager (Windows)
In Windows, the Device Manager lists all the hardware devices connected to your computer. Check if your printer is listed correctly and without any errors.
- Open Device Manager (search for it in the Start menu).
- Expand the “Printers” or “Universal Serial Bus controllers” section.
- Look for your Canon printer. If it has a yellow exclamation mark next to it, it indicates a problem.
- Right-click on the printer and select “Update driver” or “Uninstall device”.
- If you uninstalled the device, restart your computer and Windows will attempt to reinstall the driver automatically. You can also manually install the driver from the Canon website.
Firewall and Antivirus Interference
Sometimes, your firewall or antivirus software can block communication between your computer and printer.
Temporarily Disable Firewall and Antivirus
Temporarily disable your firewall and antivirus software to see if they are causing the problem. If the printer starts working after disabling them, you need to configure your firewall and antivirus settings to allow communication with the printer.
Consult your firewall and antivirus software documentation for instructions on how to add exceptions for your printer.
Create Firewall Exceptions
Add exceptions to your firewall for the Canon printer software and any related ports. The specific ports used by your printer can be found in the printer’s manual.
Common ports used by printers include:
- Port 80 (HTTP): Used for web-based printer management.
- Port 443 (HTTPS): Used for secure web-based printer management.
- Port 515 (LPD): Used for Line Printer Daemon protocol.
- Port 631 (IPP): Used for Internet Printing Protocol.
- Port 9100 (Raw TCP): Used for direct TCP printing.
IP Address Conflicts on a Network
In a network environment, if two devices have the same IP address, it can cause communication problems.
Configure a Static IP Address for the Printer
To avoid IP address conflicts, you can configure a static IP address for your printer. This means assigning a specific IP address to the printer that will not change.
- Access your printer’s network settings menu (refer to your printer’s manual).
- Disable DHCP (Dynamic Host Configuration Protocol). This will prevent the printer from automatically obtaining an IP address.
- Enter a static IP address, subnet mask, and gateway. Make sure the IP address is within the same network range as your other devices but is not already in use. You can find the subnet mask and gateway settings from your router’s configuration page.
- Save the settings.
You may need to restart the printer for the changes to take effect.
Contacting Canon Support
If you’ve tried all the troubleshooting steps and your Canon printer is still offline, it’s time to contact Canon support. They may be able to provide more specific assistance or diagnose a hardware problem.
Have your printer model number and serial number ready when you contact support. Also, be prepared to describe the troubleshooting steps you’ve already tried.

Why is my Canon printer showing as offline even though it’s turned on?
Your Canon printer appearing offline despite being powered on can stem from several factors. A common cause is a broken or unstable connection between your printer and your computer. This could be due to issues with the USB cable (if connected directly), a problem with your Wi-Fi network, or a driver malfunction preventing proper communication.
Another possibility is that your printer is paused, set to “use printer offline,” or experiencing an IP address conflict with another device on your network. These software-related issues can trick your computer into believing the printer is unavailable, even when it is physically online and ready to print. Regularly checking your network settings and print queue can often resolve these situations.
How do I check my Canon printer’s connection to my Wi-Fi network?
Firstly, navigate to the printer’s control panel. Most Canon printers have an LCD screen where you can access the settings menu. Look for options like “Wireless LAN setup,” “Wi-Fi settings,” or something similar, and select it. This should display the current Wi-Fi network your printer is connected to and its signal strength.
Alternatively, you can use the Canon PRINT Inkjet/SELPHY app on your smartphone or tablet. Ensure your mobile device is connected to the same Wi-Fi network as your printer. The app should automatically detect your printer. If it doesn’t, you may need to manually add it using its IP address. The app also provides information on the network connection status and allows you to change Wi-Fi settings if needed.
What does it mean if my Canon printer has an IP address conflict?
An IP address conflict occurs when two or more devices on the same network are assigned the same IP address. This can prevent your Canon printer from communicating properly with your computer and result in it showing as offline. The router becomes confused about which device to send data to, causing communication errors.
To resolve this, you can either assign a static IP address to your printer or configure your router to use DHCP reservation. A static IP address ensures that the printer always uses the same unique IP address, preventing conflicts. DHCP reservation allows the router to automatically assign a specific IP address to the printer based on its MAC address, ensuring consistency and avoiding conflicts. Consult your router’s documentation for instructions on setting up DHCP reservation.
How do I update my Canon printer drivers?
The most straightforward method is to visit the official Canon website and navigate to the support section for your specific printer model. Search for “drivers” and download the latest version available for your operating system (Windows or macOS). Close any programs using the printer and run the downloaded installer, following the on-screen instructions to complete the installation.
Alternatively, on Windows, you can use Device Manager. Locate your printer under “Print queues” or “Other devices,” right-click on it, and select “Update driver.” Choose “Search automatically for updated driver software,” and Windows will attempt to find and install the latest driver from the internet. If this doesn’t work, try the first method using the Canon website.
My Canon printer is paused. How do I unpause it?
To unpause your Canon printer on Windows, first, search for and open “Devices and Printers” in the control panel. Locate your Canon printer icon, right-click on it, and select “See what’s printing.” This will open the print queue window, displaying any pending print jobs and the printer’s status.
If the printer is paused, you’ll see “Paused” indicated. In the print queue window, click on “Printer” in the menu bar. There will be an option labeled “Pause Printing.” If there is a checkmark next to it, click it to remove the checkmark and unpause the printer. This should allow pending print jobs to resume.
What should I do if my Canon printer is set to “Use Printer Offline”?
Similar to unpausing the printer, you need to access the print queue. Search for and open “Devices and Printers” in the Windows control panel. Locate your Canon printer icon, right-click on it, and select “See what’s printing.” This opens the printer’s print queue, showing its status.
In the print queue window, click on “Printer” in the menu bar. If the option “Use Printer Offline” has a checkmark next to it, click it to remove the checkmark. This will switch the printer back to online mode, allowing it to communicate with your computer and print normally, assuming other connectivity issues are resolved.
I’ve tried everything, and my Canon printer is still offline. What are my next steps?
If you have exhausted all basic troubleshooting steps, consider performing a power cycle on your printer, your computer, and your router. Turn off all three devices, wait for a minute or two, then turn them back on in the following order: router, computer, and finally the printer. This can often resolve temporary glitches and re-establish the connection.
If the issue persists, contact Canon’s customer support for further assistance. They may be able to provide specific troubleshooting steps based on your printer model or identify a hardware issue that requires repair.
