1. Check Your Printer’s Power and Basic Connections

Before diving into technical troubleshooting Canon printer not connecting to computer, start with the simplest checks.

Make sure:

1. The canon printer is turned on and displays no error lights.

2. The USB cable (if you’re using one) is securely plugged into both the printer and computer.

3. You’re using a working USB port.

4. For wireless printers, your Canon printer is connected to the same Wi-Fi network as your computer.

A loose cable or mismatched Wi-Fi network is one of the most common reasons a Canon printer won’t connect.

2. Restart the Printer, Computer, and Router

A restart can clear temporary software glitches and reset network connections.

Do this:

1. Turn off your Canon printer and unplug it for 30 seconds.

2. Restart your computer.

3. Restart your router if you’re using Wi-Fi.

Once everything powers back up, try connecting the printer again. This simple step often solves connection issues instantly.

3. Reconnect the Printer to Wi-Fi (for Wireless Models)

If your Canon printer won’t connect to your computer (Call USA/CA: +1-8O1-878-6858) via Wi-Fi, the printer may have disconnected from the network or the network name/password may have changed.

Reconnect using the printer’s menu:

1. Go to Setup or Settings on the printer screen.

2. Select Wireless LAN Setup.

3. Choose your Wi-Fi network name.

4. Enter your Wi-Fi password.

If the printer fails to connect:

1. Move it closer to the router.

2. Ensure your router isn’t using a 5GHz-only network (many Canon printers only support 2.4GHz Wi-Fi).

After reconnecting, try adding the printer again on your computer.

4. Reinstall or Update Canon Printer Drivers

Outdated or corrupted drivers are a frequent cause of connection problems—especially after a system update on Windows or macOS.

How to fix it:

1. Visit the Canon Support website.

2. Enter your printer model.

3. Download the latest driver for your operating system.

4. Install the driver and restart your computer.

For Windows users:

You can also update drivers via:

1. Device Manager

2. Windows Update

Once updated, your computer should detect the printer again.

5. Add the Printer Manually

Sometimes your computer doesn’t automatically detect the Canon printer, even when it’s properly connected. Adding it manually often resolves the issue.

On Windows:

1. Go to Settings > Bluetooth & devices > Printers & scanners.

2. Click Add a printer or scanner.

3. If your printer doesn’t appear, select The printer I want isn’t listed.

4. Choose the appropriate detection option (Wi-Fi, USB, or IP address).

On Mac:

1. Open System Settings > Printers & Scanners.

2. Click Add Printer (+).

3. Select your Canon printer from the list.

4. If it doesn’t appear, try adding it using IP and entering the printer’s IP address.

This step helps the system recognize your printer manually when auto-detection fails.

6. Disable “Use Printer Offline” or Pause Mode

If your Canon printer is showing as “Offline” even though it’s connected, your computer might be blocking communication.

Windows:

1. Open Printers & scanners.

2. Select your Canon printer and click Open Print Queue.

3. Ensure “Use Printer Offline” is unchecked.

Mac:

1. Go to Printers & Scanners.

2. Select the printer and check if it’s paused.

3. If paused, click Resume.

Once corrected, your computer should communicate with the printer normally.

7. Reset Network Settings or Perform a Factory Reset

If nothing else works, your printer’s internal settings may be corrupted. Resetting them often resolves deep connection issues.

To reset network settings:

1. Open Setup on the printer’s display.

2. Choose Device Settings.

3. Select Reset LAN Settings.

For a full factory reset:

1. Go to Device Settings again.

2. Choose Reset All or Restore Defaults.

After the reset:

1. Reconnect your Canon printer to Wi-Fi.

2. Reinstall the printer on your computer.

This gives you a clean start, removing any configuration conflicts.
