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.
Caution
•
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.
