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 2 to 3 minutes.
• Deep cleaning
Use this mode if no ink is ejected at all or if Cleaning does not solve the problem.
It takes about 3 minutes.
• System cleaning
Use this mode 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 4 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.
• When using cut sheets, do not move the release lever until instructions (guidance) for removing the
paper are displayed.
Moving the release lever during printing or maintenance operations will cause the printer to stop.
Note
• Check the nozzle check pattern and select an ink group for which to perform cleaning as needed. You
can clean all print heads or select pattern 1 or 2 to clean the print heads with a clogged nozzle.
