How do I perform a print head cleaning cycle on a Canon G3000 series printer, and when should I do it?

Access the printer's maintenance menu through the LCD screen (usually by navigating to Settings > Maintenance > Print Head Cleaning). Follow the on-screen prompts. Perform a cleaning cycle when you notice faded prints, streaks, or missing colors. Avoid excessive cleaning as it consumes ink; try a power cycle first. If cleaning doesn't work, try a deep cleaning cycle (if available).
