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.740
2. Print a test pattern to check the nozzles.
Note
• If you repeat these steps several times but the horizontal lines are still faint or incomplete, contact
your Canon dealer.
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 re-
solve.
• 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.
