How to Fix Canon Printer Error 1551

Follow these troubleshooting steps in order. After each step, check whether the error has been resolved.

Restart the printer.

Temporary software glitches can sometimes trigger Error 1551.

Steps:

1. Turn off the printer.

• Physical damage
• Protective tape still attached
• Ink leakage
• Correct cartridge model

Remove and reinstall each cartridge carefully until it clicks into place.

Clean the Print Head Contacts

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

To clean them:

1. Remove the ink cartridges.
2. Remove the print head if your printer model allows it.
3. Use a lint-free cloth slightly dampened with distilled water.
4. Gently wipe the gold-colored contacts.
5. Allow the contacts to dry completely.
6. Reinstall the print head and cartridges.

Avoid touching the contacts with your fingers.

Perform a Printer Reset

Resetting the printer can clear temporary internal errors.

To perform a basic reset:

1. Turn off the printer.
2. Disconnect the power cable.
3. Wait one minute.
4. Reconnect the power.
5. Turn the printer on again.

For some Canon models, restoring factory settings through the printer menu may also help.

Update the printer driver.

Outdated drivers can sometimes cause communication problems between your computer and printer.

Update your printer driver by:

• Downloading the latest driver for your printer model.
• Installing the updated software.
• Restarting your computer.
• Testing the printer again.

Keeping the driver current improves compatibility with newer operating systems.

Small pieces of paper, labels, or foreign objects inside the printer can interfere with the printer’s startup sequence.

Inspect:

• Paper path
• Rear access area
• Cartridge carriage
• Print head movement

Carefully remove any debris before restarting the printer.
