Cleaning the Print Heads from Your Computer
The print head cleaning function allows you to clear up clogged print head nozzle. Perform
print head cleaning if printing is faint or a specific color fails to print, even though there is
enough ink.
The procedure for cleaning the print head is as follows:
Cleaning
1. Select Cleaning from the pop-up menu on the Canon IJ Printer Utility
2. Click the Cleaning icon
When the dialog opens, select the ink group for which cleaning is to be performed.
Click to display the items you need to check before performing cleaning.
3. Execute cleaning
Make sure that the machine is on and then click OK .
Print head cleaning starts.
4. Complete cleaning
The Nozzle Check dialog opens after the confirmation message.
5. Check the results
To check whether the print quality has improved, click Print Check Pattern . To
cancel the check process, click Cancel .
If cleaning the head once does not resolve the print head problem, clean it once
more.
Important
Cleaning consumes a small amount of ink.
Cleaning the print head frequently will rapidly deplete your printer's ink supply.
Consequently, perform cleaning only when necessary.
