Cleaning the Print Head If printing is faint, cleaning the print head may improve results. Choose one of three print head cleaning modes (Cleaning, Deep cleaning, or System cleaning), depending on the problem to resolve. • Cleaning Use this mode if printing is faint or contains foreign substances. This method of cleaning consumes the least amount of ink. It takes about 8 minutes. • Deep cleaning Use this mode if no ink is ejected at all or if Cleaning does not solve the problem. It takes about 8 or 9 minutes. • System cleaning Use this if printing is not improved after Deep cleaning. System cleaning consumes a very large amount of ink. Performing this frequently consumes the ink faster. Perform this only when needed. It takes about 10 minutes. Important • Do not remove the maintenance cartridge or ink tanks during Cleaning, Deep cleaning, or System cleaning. Ink may leak or an error may occur. • If printing is not improved after System cleaning, the print head may be at the end of its service life. Contact your Canon dealer for assistance. Note • Check the nozzle check pattern and select an ink group for which to perform cleaning as needed. You can clean all print head or select pattern 1, 2, or 3 to clean the print head with a clogged nozzle. 311
