Cleaning The Print Head Deeply - Canon Pixma MX520 Series Online Manual

Cleaning the Print Head Deeply

If print quality does not improve by the standard cleaning of the print head, clean the print head deeply. Cleaning the print
head deeply consumes more ink than the standard cleaning of the print head, so clean the print head deeply only when
necessary.
