Important
• Do not touch the Linear Scale (a),
Carriage Shaft (b), or Fixed Blade (c).
This may stain your hands and damage
the printer.
• Do not use a dry cloth to wipe inside the Top Cover. This may create a static charge,
which may attract dust and affect the printing quality.
• Do not touch the clear sheet on the side of the Top Cover Roller. This may damage the
roller.

Close the Top Cover.
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 four 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 five minutes to complete.
Important
• Do not remove the Maintenance Cartridge or ink tanks during either Head Cleaning A or Head
Cleaning B.
Ink may leak or an error may occur.
• If printing does not improve even if you execute 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.
