Printheads
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 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 three and a half 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.
