Canon Printer Won’t Turn On: Causes, Fixes, and Complete Troubleshooting Guide

 When your canon printer wont turn on, it can be incredibly frustrating—especially when you need to print something important at the last minute. Canon printers are known for reliability, but like any electronic device, they may occasionally fail to power on due to hardware issues, power faults, or internal glitches. The good news? Most of these problems can be fixed at home with simple troubleshooting steps.

In this comprehensive guide, we’ll walk you through all the major reasons why your Canon printer won’t turn on and provide step-by-step solutions to get your device up and running again. Whether you're using a Canon inkjet, laser, or multifunction printer, this guide covers everything you need to know.

1. Why Your Canon Printer Won’t Turn On

Several factors can cause a Canon printer to stop powering up. Understanding these reasons makes it easier to identify the root cause and fix it quickly.

1.1. Power Cable Issues

Loose, damaged, or incorrectly connected power cables are the most common reasons a Canon printer fails to turn on. Even a minor disconnection can interrupt the power supply.

1.2. Faulty Power Outlet

Sometimes the issue is not with the printer but with the wall socket or extension board you're using.

1.3. Internal Power Supply Failure

Canon printers have internal power boards. If these components fail, the printer stays completely unresponsive.

1.4. Overheating or Power Surge

Printers have built-in safety mechanisms. If your device overheated or experienced a surge, it might stay off until it resets.

1.5. Firmware Glitches

A failed update or corrupted firmware can sometimes cause the printer to freeze during startup.

1.6. External Damage

Physical damage or moisture exposure can also prevent the printer from turning on.

2. Initial Checks Before Troubleshooting

Before diving into deeper fixes, perform these quick checks:

✔ Is the power cable securely connected?
✔ Is the socket working?
✔ Is the printer’s power button functional?
✔ Has the printer recently stopped due to a storm or power outage?
✔ Are you using the original Canon power adapter (for certain models)?

If everything looks okay, move on to the troubleshooting steps below.

3. Step-by-Step Fixes for a Canon Printer That Won’t Turn On

This section provides detailed solutions that work for most Canon printer models.

3.1. Check the Power Cable and Connection

  1. Disconnect the power cable from the printer.

  2. Inspect both ends of the cable for cuts, bends, or signs of damage.

  3. Reconnect the cable firmly into the printer’s power port.

  4. Plug the other end directly into a wall socket (not an extension cord).

  5. Press the power button for 3–5 seconds.

If the printer turns on, your issue was simply a loose connection.

3.2. Test the Power Outlet

To confirm the outlet is working:

  • Plug in another device like a phone charger or lamp.

  • If it doesn’t work, try a different wall socket.

  • Avoid using surge protectors or extension boards for testing.

A faulty outlet is more common than many people realize.

3.3. Power Reset the Printer (Hard Reset)

A hard reset can solve internal glitches.

How to perform a hard reset:

  1. Turn off the printer (if possible).

  2. Unplug the power cord from the back of the printer.

  3. Wait 60 seconds.

  4. Press and hold the printer's power button for 15 seconds (this discharges residual power).

  5. Plug the cable back in and try turning the printer on.

Many users report this method instantly revives a dead Canon printer.

3.4. Remove Any Connected USB Cables or Devices

USB cables, memory cards, or even wireless adapters sometimes interfere with startup.

  • Disconnect all cables and accessories.

  • Try powering on the printer with just the power cable connected.

3.5. Inspect for Power Surges or Overheating

If your printer suddenly shut down:

  • Feel the printer body—does it feel unusually hot?

  • If yes, unplug it and allow it to cool for 10–20 minutes.

Canon printers may temporarily disable themselves to prevent electrical damage.

3.6. Try a Different Power Cable (If Compatible)

Some Canon printers use standard detachable power cords. If you have another compatible cable:

  • Swap the cable and test again.

  • If the printer turns on with a different cord, replace the old one.

3.7. Check the Printer’s Power Button

The power button may be:

  • Jammed

  • Broken

  • Not making proper contact internally

Try pressing gently and repeatedly. If it feels stuck, dust or mechanical wear might be the cause.

3.8. Reset the Printer’s Internal Power Supply

Certain Canon models have removable power modules.

If your model includes an external or semi-detachable power supply:

  1. Remove the power module (if possible).

  2. Leave it disconnected for 10 minutes.

  3. Reinstall it and plug in the printer.

If the internal supply is burned out, you may notice:

  • Burning smell

  • Clicking noise

  • No LED indicators

  • Printer won't respond at all

In such cases, you may need professional repair.

3.9. Check for Firmware Corruption

Firmware issues usually occur after:

  • Interrupted updates

  • Sudden power loss

  • Long periods without usage

If your printer shows no lights at all, firmware may be frozen.

Try the following:

  1. Disconnect power.

  2. Hold down the Stop/Cancel button (if available).

  3. While holding it, plug in the power cable.

  4. Release after 5 seconds.

This forces the printer to attempt a recovery boot.

3.10. Inspect for Physical Damage or Moisture

Look for signs such as:

  • Liquid spills

  • Rust or corrosion

  • Cracks or dents

  • Burn marks

Moisture or physical impact often damages the internal circuit board, requiring service.

4. Advanced Troubleshooting Techniques

If your Canon printer still won’t turn on, try these expert-level solutions:

4.1. Use a Different Power Adapter (Canon Models with AC Adapters)

Some models, especially portable or compact printers, use external adapters. If the adapter is dead, the printer won’t start.

  • Replace with a genuine Canon adapter.

  • Avoid third-party adapters as they may not provide stable voltage.

4.2. Check for Blown Fuses Inside the Printer (Service Level)

Warning: Only trained technicians should open the printer.

Canon printers have onboard fuses that protect electronics from surges. If a fuse blows, the printer becomes completely unresponsive.

A technician can:

  • Test the fuse with a multimeter

  • Replace damaged components safely

4.3. Diagnose with Canon Printer Support Mode

Some Canon printers have hidden diagnostic modes. If the printer at least shows a faint LED or flickers, a technician may access deeper diagnostics.

5. When Should You Contact Canon Support?

You should contact support if:

  • The printer shows no lights at all

  • You smell something burning

  • The printer turns on and immediately shuts down

  • There was a recent power surge or lightning strike

  • The printer is still under warranty

Attempting repairs on your own could void warranty coverage, so proceed carefully.

6. How to Prevent Your Canon Printer from Failing to Turn On

Prevention is the best cure. Follow these tips:

✔ Use a Surge Protector

Protects your printer from voltage spikes.

✔ Keep the Printer in a Dry, Dust-Free Environment

Moisture and dust cause internal damage.

✔ Avoid Long Periods of Inactivity

Use the printer at least once a week to keep circuits active.

✔ Regular Maintenance

Clean the printer and inspect cables regularly.

✔ Update Firmware Carefully

Never interrupt firmware updates.

7. Final Thoughts

When your Canon printer won’t turn on, it doesn’t always mean the device is permanently damaged. In many cases, the issue is as simple as a loose cable, a faulty socket, or a temporary internal glitch. By following the troubleshooting steps in this guide, you can often get your printer working again without needing professional help.
