Check the printing results.
If the horizontal lines are not faint or incomplete, the nozzles are
clear.
If some sections of the horizontal lines are faint or incomplete, the
nozzles for those colors are clogged.
If horizontal lines are faint or incomplete, follow the steps below
and check again for nozzle clogging.
1.
Clean the Printhead. (See "Cleaning the Printhead.") →P.846

Important
• If you repeat these steps several times but the horizontal lines are still faint or incomplete, contact your Canon
dealer.
Cleaning the Printhead
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 six 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 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.
