Solutions

Quick Diagnosis

If the error 1405 is persistent, take the head out and look for dried ink covering the electrical contact pins on the back. Ink deposits there are a primary cause of communication errors.

Step-by-Step Solution

  1. Extraction: Power on the printer, open the cover, and pull the locking lever to remove the printhead.
  2. Clean: Clean the electrical contacts with a lint-free cloth and a very small amount of isopropyl alcohol.
  3. Reseat: Reinstall the printhead carefully, ensuring a snug connection.

Prevention and Maintenance

Avoid handling the electrical pins with greasy fingers. Stick to OEM Canon inks to prevent clogging of the tiny printhead nozzles and subsequent circuit damage.

When to Contact a Technician

If you have cleaned the contacts several times and still receive the 1405 error, the printhead assembly is likely fried and requires replacement.
