If print quality does not improve by standard print head cleaning, try print head deep cleaning, which is a more powerful process. Print head deep cleaning consumes ink, so perform this procedure only when necessary.
2 Open the Printer Properties dialog box.
See Opening the Printer Properties dialog box directly from the Start menu
3 Start Print Head Deep Cleaning.
(3) Select the ink nozzles to be cleaned, and then click Execute.
All colors: All nozzles
Black: Black ink nozzles
Color: Color ink nozzles
(4) When the message is displayed, click OK.
2 Open the Printer Utility dialog box.
(1) Select Page Setup... in the File menu.
(2) Click Utilities to open the Printer Utility dialog box.
3 Start Print Head Deep Cleaning.
(1) Select Cleaning from the pull-down menu.
(3) Select the ink nozzles to be cleaned, and then click OK.
All colors: All nozzles
Black: Black ink nozzles
Color: Color ink nozzles
(4) When the message is displayed, click OK.
The process takes one or two minutes to complete, so simply wait until the POWER lamp stops flashing.
Note
After print head deep cleaning finishes, print the nozzle check pattern to verify that the print head nozzles are clean.
See Printing the Nozzle Check Pattern
If the head is still not clean after the second deep cleaning, the print head may be worn out. In this event, contact a Canon service representative.
