How do I perform a deep cleaning on my Canon printer to resolve persistent color issues?

A deep cleaning cycle is more thorough than the standard nozzle check cleaning. Access this option through the printer driver or control panel. It typically involves a longer cleaning process that addresses more stubborn clogs. However, be aware that deep cleaning uses more ink, so only run it if the standard cleaning doesn't resolve the problem. Refer to your printer's manual for the specific deep cleaning procedure.
