Canon Printer Cannot Detect USB

by

If your Canon printer cannot detect the USB connection, it usually means there’s a problem with the USB cable, port, driver, or printer settings. This issue prevents your computer from recognizing the printer, meaning you can’t print or scan over USB.

Here’s a complete step-by-step guide to troubleshoot and fix the problem.

1. Check the USB Cable and Connection

Use a Different USB Cable
  • Try a new or known-working USB cable.
  • Make sure the cable is not damaged, overly long, or low quality.

Use a Different USB Port
  • Plug the USB into a different USB port on your computer (preferably USB 2.0).
  • Avoid USB hubs, extenders, or docking stations – connect directly to the computer.

Fully Insert the Cable
  • Ensure both ends are securely connected – to the printer and the computer.

2. Power Cycle the Printer and Computer
  1. Turn off the printer and unplug it.
  2. Shut down your computer.
  3. Wait 30 seconds.
  4. Plug in the printer, turn it on, and restart your computer.
  5. Reconnect the USB cable and check detection.

3. Confirm USB Connection on the Printer (if model supports it)

Some Canon printers allow switching between USB and network modes.

  • Go to Settings > Device Settings > USB Settings (or similar).
  • Make sure USB is enabled as a connection method.

4. Check Windows or macOS Recognition

Windows
  1. Press Windows + R, type devmgmt.msc and press Enter (opens Device Manager)
  2. Expand Printers or Universal Serial Bus Controllers
  3. Look for your Canon printer
    • If it’s listed with a yellow triangle, the driver is not working properly
    • If it’s not listed, try another cable or port

You can also check under:

  • Control Panel > Devices and Printers
  • If the printer is missing, Windows isn’t detecting it

macOS
  1. Go to System Settings > Printers & Scanners
  2. If the Canon printer isn’t listed, click the + button to add it
  3. If it’s still not visible, try a different port or cable

5. Reinstall or Update the Printer Driver

Step-by-Step:
  1. Go to Canon Support
  2. Enter your printer model
  3. Download the USB driver, printer driver, and utility software for your operating system
  4. Uninstall any existing Canon software
  5. Reinstall using the newly downloaded files
  6. Restart your computer and reconnect the USB cable

6. Check the Print Spooler (Windows Only)
  1. Press Windows + R, type services.msc, and press Enter
  2. Scroll to Print Spooler
  3. Right-click > Restart
  4. Try reconnecting the printer

7. Run the Printer Troubleshooter (Windows Only)
  1. Go to Settings > System > Troubleshoot > Other Troubleshooters
  2. Select Printer > Run
  3. Follow the on-screen instructions to detect and fix issues

8. Try Another Computer
  • Connect the printer via USB to a different computer.
  • If it works, the issue is with your original system.
  • If not, the printer’s USB port may be faulty.

9. Firmware Update (if applicable)
  • Go to Canon’s support site, download the latest firmware for your printer
  • Follow the instructions carefully
  • Some connection issues are resolved by updating the firmware via USB or network

10. When to Contact Canon Support

Contact Canon if:

  • The printer still isn’t detected via USB after trying new cables, ports, and drivers
  • The USB port on the printer feels loose or damaged
  • You’re using a new OS version and no compatible drivers are available
  • You suspect a hardware failure in the printer’s USB controller

Canon support can help with hardware diagnostics or offer repair/warranty options.
