Solutions

Quick Diagnosis

Error 1401 displays when the printer cannot identify the ink cartridges. If you have recently changed the ink or moved the device, the electrical contacts may have shifted or collected debris, preventing a clear signal.

Step-by-Step Solution

  1. Check Power: Ensure the device is plugged in and powered on.
  2. Access Carriage: Lift the scanner unit to reach the cartridge holder.
  3. Remove Ink: Release and pull out both cartridges.
  4. Clean: Wipe the gold electrical contacts on the cartridges with a clean, dry cloth.
  5. Install: Insert the cartridges back into their respective slots until they snap into place.

Prevention and Maintenance

Handle ink cartridges by the plastic casing rather than the gold contact chip to prevent residue buildup. Use only genuine Canon ink to ensure longevity of the print head. Keep the printer area dust-free to avoid mechanical blockages.

When to Call a Technician

If you have performed a thorough cleaning of the contacts and tried a new set of cartridges without success, the print head may have suffered an internal electrical failure that requires professional repair.
