If your Canon printer displays Canon Printer Error 1403, it usually indicates that the printer cannot detect or properly communicate with the print head. This error can prevent the printer from printing, scanning, or copying until the issue is resolved. While the message may seem alarming, it is often caused by a loose print head, dirty electrical contacts, incompatible ink cartridges, or a temporary firmware issue.

In this guide, you’ll learn what Canon Printer Error 1403 means, its most common causes, proven troubleshooting steps, when to replace the print head, and how to prevent the error from returning.

What Does Canon Printer Error 1403 Mean?

Canon Printer Error 1403 is a hardware-related error that indicates the printer cannot recognize the installed print head. Since the print head is responsible for transferring ink onto paper, the printer will stop operating when it cannot communicate with this component.

Depending on your Canon printer model, you may also see messages such as the following:

• Print Head Not Installed
• The Type of Print Head Is Incorrect
• Print Head Error
• Support Code 1403
• Printer Error 1403

Ignoring the error can eventually affect print quality and may prevent the printer from functioning altogether.

Common Causes of Canon Printer Error 1403

Several issues can trigger Canon Printer Error 1403.

The most common causes include:

• Loose or improperly installed print head
• Dirty print head electrical contacts
• Damaged print head
• Defective ink cartridges
• Non-genuine or incompatible cartridges
• Firmware glitches
• Power interruption during printing
• Internal printer hardware failure

Identifying the exact cause helps determine the fastest solution.

How to Fix Canon Printer Error 1403

Follow these troubleshooting methods in order.

Restart the printer.

A simple restart can clear temporary hardware communication errors.

Steps:

1. Turn off the printer.
2. Unplug the power cable.
3. Wait for two minutes.
4. Plug the printer back in.
5. Turn it on again.

If the error disappears, no further troubleshooting is needed.

Check the print head installation.

A slightly misaligned print head is one of the most common reasons for Error 1403.

To inspect it:

1. Open the printer cover.
2. Wait for the carriage to stop moving.
3. Remove all ink cartridges.
4. Unlock the print head lever.
5. Remove the print head carefully.
6. Reinstall it firmly.
7. Lock the lever securely.
8. Reinsert the cartridges.

Restart the printer after reinstalling the print head.

Clean the Print Head Contacts

Dirty electrical contacts can interrupt communication between the printer and the print head.

To clean them safely:

• Turn off the printer.
• Remove the print head.
• Use a lint-free cloth slightly dampened with isopropyl alcohol.
• Gently clean the gold-colored contacts.
• Allow the contacts to dry completely.
• Reinstall the print head.

Avoid touching the nozzles directly.

Inspect the Ink Cartridges

Faulty cartridges can also trigger Canon Printer Error 1403.

Check for:

• Empty cartridges
• Damaged chips
• Protective tape left on new cartridges
• Incorrect cartridge model
• Poor cartridge installation

If necessary, replace damaged cartridges with compatible replacements.

Perform a Printer Reset

Resetting the printer may clear temporary firmware issues.

Basic reset procedure:

1. Turn off the printer.
2. Disconnect the power cord.
3. Wait for five minutes.
4. Hold the Power button for 30 seconds.
5. Reconnect power.
6. Restart the printer.

Some Canon printer models also include factory reset options in the Settings menu.

Update Printer Firmware

Outdated firmware may occasionally cause print head communication problems.

Firmware updates can:

• Improve printer stability
• Fix known bugs
• Enhance hardware compatibility
• Resolve communication issues

Always avoid interrupting a firmware update once it has started.

Reinstall the printer driver.

Corrupted drivers may generate misleading printer errors.

Driver reinstallation steps:

1. Remove the existing Canon printer.
2. Uninstall the printer driver.
3. Restart the computer.
4. Install the latest compatible driver.
5. Add the printer again.

This process resolves many communication-related issues.

Signs That the Print Head Needs Replacement

If none of the troubleshooting methods work, the print head itself may have failed.

Common warning signs include:

• Persistent Error 1403
• Blank pages after cleaning
• Missing colors
• Streaked prints
• Printer repeatedly fails print head detection
• Frequent print quality issues

Replacing the print head is often the only permanent solution if it is electrically damaged.

Common Mistakes to Avoid

Many users accidentally make the problem worse.

Avoid these mistakes:

• Forcing the print head into position
• Installing incompatible cartridges
• Cleaning contacts with excessive liquid
• Touching print head nozzles
• Interrupting firmware updates
• Using damaged cartridges
• Ignoring recurring error messages

Following proper maintenance procedures reduces the risk of additional damage.

How to Prevent Canon Printer Error 1403

Regular maintenance helps prevent future print head problems.

Best practices include:

• Print at least once each week.
• Use genuine or high-quality compatible cartridges.
• Keep the printer clean.
• Avoid sudden power interruptions.
• Update firmware periodically.
• Replace leaking cartridges immediately.
• Store unused cartridges properly.
• Turn off the printer using the Power button instead of unplugging it.

Preventive maintenance extends both printhead and printer life.

When Should You Contact Canon Support?

Professional repair may be necessary if:

• Error 1403 returns immediately after replacing the print head.
• Multiple print heads fail.
• The printer reports additional hardware errors.
• The carriage mechanism does not move.
• Internal electronics appear damaged.

These symptoms usually indicate a motherboard or hardware communication failure.

Frequently Asked Questions

Is Canon Printer Error 1403 caused by bad ink cartridges?

Sometimes. Faulty or incompatible cartridges can prevent proper communication with the print head and trigger Error 1403.

Can I continue printing with Error 1403?

No. Most Canon printers disable printing until the print head issue is resolved.

Does cleaning the print head fix Error 1403?

If dirty electrical contacts are causing the problem, cleaning the print head can often resolve the error.

Will replacing the print head always solve the issue?

Not always. If the printer’s logic board is damaged, replacing the print head alone may not fix the error.

Can firmware updates prevent Error 1403?

Firmware updates can resolve software-related communication issues but cannot repair a physically damaged print head.

Conclusion

Canon Printer Error 1403 usually indicates that the printer cannot detect or communicate with the print head. In many cases, the issue can be resolved by reseating the print head, cleaning the electrical contacts, checking the ink cartridges, updating the firmware, or reinstalling the printer driver. If the error persists after completing all troubleshooting steps, the print head or another internal hardware component may need replacement. Regular maintenance and proper cartridge installation can help prevent Canon Printer Error 1403 from occurring again.
