Canon printers are known for their reliability, advanced features, and user-friendly designs. However, like any device, they occasionally encounter issues.

While these codes may look intimidating, they serve a valuable purpose: helping you pinpoint what’s wrong.

Here, we’ll explore the most common Canon printer error codes, explain what they mean, and provide actionable steps to fix them. Whether you’re using a Canon Pixma, imageCLASS, or imageRUNNER series printer, this blog will help you troubleshoot issues efficiently and get your printing back on track.

1. Error Code 5100: Ink Cartridge or Carriage Jam

What it means:
This code indicates a carriage problem—often due to a paper jam, foreign object, or misaligned ink cartridge.

How to fix it:

  • Turn off the printer and unplug it.
  • Open the printer cover and check for any paper, packaging material, or debris obstructing the carriage path.
  • Gently move the carriage to ensure it can move freely.
  • Remove and reseat the ink cartridges.
  • Plug the printer back in and restart it.

Pro Tip: Always use genuine Canon ink cartridges to reduce the risk of carriage issues.

2. Error Code B200: Printhead or Hardware Fault

What it means:
B200 is a critical error related to the printhead or internal electronics. It may point to overheating or malfunction.

How to fix it:

  • Turn off the printer and unplug it.
  • Open the top cover and carefully remove the ink cartridges and printhead.
  • Clean the printhead contacts with an isopropyl alcohol.
  • Let everything dry and reinstall the printhead and cartridges.
  • Restart the printer.

If the error persists:
It could indicate a hardware issue that requires professional service or a printhead replacement.

3. Error Code E05 / E07: Cartridge Not Recognised

What it means:
These errors suggest the printer cannot detect the ink cartridge, or it’s installed incorrectly.

How to fix it:

  • Turn off the printer and open the cartridge compartment.
  • Remove and inspect the cartridges. Make sure there’s no protective tape left on the ink nozzles or chip.
  • Clean the cartridge chip with a soft, dry cloth.
  • Reinsert the cartridges firmly into their slots.
  • Restart the printer.

Note: Non-genuine or refilled cartridges may cause detection issues. Use Canon-approved consumables for best results.

4. Error Code E03: Paper Jam

What it means:
The printer has detected a paper jam, typically during loading or printing.

How to fix it:

  • Turn off the printer and open all accessible panels.
  • Carefully remove any jammed or crumpled paper. Avoid tearing it.
  • Check the rear tray and internal rollers for hidden bits of paper.
  • Once clear, close all covers and restart the printer.

Preventative tip: Use the recommended paper size and avoid overloading the paper tray.

5. Error Code 5B00 / 5B02: Waste Ink Tank Full

What it means:
Canon printers use a waste ink absorber to collect excess ink during cleaning cycles. This error means the absorber is full.

How to fix it:

  • This is not user-serviceable in most models.
  • Contact an authorised Canon service centre to replace the waste ink pad.
  • Some advanced users attempt manual resets, but this is not recommended as it can void your warranty.

6. Error Code 6000: Paper Feed or Sensor Issue

What it means:
The printer is having trouble feeding paper—usually due to obstruction or sensor faults.

How to fix it:

  • Power off the printer and remove any paper in the tray.
  • Check the paper feed area for dust, scraps, or small obstructions.
  • Use compressed air to clean the feed rollers.
  • Ensure paper is loaded correctly—not bent or damp.

If unresolved:
It may be a damaged sensor or roller issue that requires professional repair.

7. Error Code 1401 / 1403: Faulty or Missing Printhead

What it means:
The printer is not recognising the printhead, or the printhead is faulty.

How to fix it:

  • Power off the printer and remove the ink cartridges and printhead.
  • Clean the electrical contacts on the printhead and carriage.
  • Reinstall the printhead and ink cartridges.
  • Restart the printer.

If the issue continues:
You may need to replace the printhead. Contact Canon support for compatibility and pricing.

8. Error Code 1688: Ink Has Run Out

What it means:
The printer believes the ink cartridge is empty, even if it may still have some ink.

How to fix it:

  • Press and hold the Stop/Reset button for 5-10 seconds to override the warning and continue printing.
  • Replace the ink cartridge as soon as possible to avoid print quality issues or hardware damage.

9. Error Code U163: Cartridge Cannot Be Recognised

What it means:
This typically occurs with non-genuine cartridges or after refilling.

How to fix it:

  • Confirm the cartridge is seated properly.
  • Try resetting the printer by holding the Stop/Reset button.
  • Replace the cartridge if the issue persists.

Important: Canon printers may not support unofficial ink cartridges.

10. Error Code E02: No Paper Loaded

What it means:
The printer is expecting paper in the tray but detects none.

How to fix it:

  • Load the correct paper size into the rear tray or cassette.
  • Check for dust or blockages on the paper sensor.
  • Restart the printer after loading paper.

General Tips for Handling Canon Printer Errors

  • Keep your firmware updated: Canon regularly releases firmware updates that fix known bugs or improve compatibility.
  • Use Canon software utilities: Tools like My Printer or Canon IJ Utility can help diagnose and reset certain errors.
  • Always power off properly: Turning the printer off using the power button ensures printhead parking and prevents ink clogs.
  • Clean your printer regularly: Dust, paper bits, and ink buildup can cause many avoidable errors.

When to Seek Professional Help

If the error code:

  • Keeps recurring after multiple resets
  • Involves the printhead or internal components
  • Affects print quality despite fresh cartridges

…it’s best to contact Canon support or take your printer to an authorised service centre. Attempting complex DIY fixes may worsen the issue or void your warranty.

Conclusion

Canon printer error codes may seem frustrating, but they’re designed to help you identify and resolve problems quickly. Understanding what each code means can save you time, reduce downtime, and extend the life of your printer. By keeping your printer clean, updated, and using genuine Canon supplies, you can avoid most common issues and keep your printing tasks running smoothly.
