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 three and a half 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 four minutes to complete. • Do not remove the Maintenance Cartridge or ink tanks during either Head Cleaning A or Head Cleaning B.
