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. 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. 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. CAUTION - Do not remove the Maintenance Cartridge or ink tanks during either Head Cleaning A or Head Cleaning B.
NOTE - If printing does not improve after Head Cleaning B, try repeating Head Cleaning B once or twice. If this still does not improve 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.
Perform cleaning as follows. 1. On the Tab Selection screen of the Control Panel, press  or  to select the Settings/Adj. tab (  ).

2. Press the OK button. The Set./Adj. Menu is displayed. 3. Press  or  to select Maintenance, and then press the OK button. 4. Press  or  to select Head Cleaning, and then press the OK button. 5. Press  or  to select Head Cleaning A or Head Cleaning B, and then press the OK button. Head cleaning is now executed.
