Cleaning the Printer
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.
•
Nozzles are periodically checked to ensure they are clear. Congure the settings on the Control Panel
