Error code E05 on a Canon printer typically indicates an issue with one of the ink cartridges. This error is often associated with the “The FINE Cartridge cannot be recognized” message. Here’s how to troubleshoot and resolve error code E05:

Check the Ink Cartridges: Open the printer’s cover or access panel to access the ink cartridges. Ensure that they are correctly installed and securely seated in their respective slots.

Inspect for Protective Tape: New ink cartridges often come with a protective tape or seal that needs to be removed before installation. Check if any protective tape is still attached to the cartridges, and if so, carefully remove it.

Replace or Reinstall the Cartridges: If you have recently replaced one or more ink cartridges. It’s possible that the cartridge is not compatible or not recognized by the printer. In such cases, try reinstalling the original Canon cartridges or compatible cartridges that are specifically designed for your printer model.

Clean the Cartridge Contacts: Turn off the printer and unplug it from the power source. Gently remove the ink cartridges and inspect the metal contacts (the gold or copper-colored areas) on both the cartridge and the printer. If you see any dirt or residue, use a lint-free cloth or cotton swab lightly moistened with distilled water to clean them. Make sure the contacts are completely dry before reinstalling the cartridges.

Perform a Printer Reset: To reset the printer and clear the error, unplug it from the power source and leave it disconnected for a few minutes. Then, plug it back in and turn it on.
