What specific components should I visually inspect inside my Canon G2020 when troubleshooting Error 1723?

When troubleshooting Canon G2020 Error 1723, visually inspect the following components: 1. Print Heads: Check if they are securely latched and for any visible damage or ink residue on the contacts. 2. Ink Tanks: Ensure they are properly seated in their respective slots and have sufficient ink. 3. Print Carriage: Look for any obstructions (e.g., paper scraps, foreign objects) that might impede its movement. 4. Flexible Flat Cables (FFC): While harder to access for a casual user, ensure none appear crimped or disconnected (though this might require disassembling covers). 5. Encoder Strip: A clear, thin strip usually running across the back of the print carriage's path. Ensure it's clean and unobstructed, as damage here can cause carriage errors. Always perform these checks with the printer powered off and unplugged.
