Cleaning the Printhead If printing is faint, cleaning the Printhead may improve results. Choose one of two Printhead cleaning modes (Head Cleaning A or Head Cleaning B), depending on the problem to resolve. • Head Cleaning A Use this mode if printing is faint or contains foreign substances. This method of cleaning consumes the least amount of ink. It takes about six minutes to complete. • Head Cleaning B Use this mode if no ink is ejected at all, or if Head Cleaning A does not solve the problem. It takes about seven minutes to complete. • Do not remove the Maintenance Cartridge or ink tanks during either Head Cleaning A or Head Cleaning B. Caution • If printing does not improve after Head Cleaning B, try repeating Head Cleaning B once or twice. If this still does not improve Note printing, the Printhead may have reached the end of its useful life. Contact your Canon dealer for assistance. • Nozzles are periodically checked to ensure they are clear. Configure the settings on the Control Panel menu in Nozzle Check.
