Print Head Deep Cleaning

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.

The process takes one or two minutes to complete, so simply wait until the Power lamp stops flashing.
After print head cleaning finishes
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" on page 38.
When one specific color only does not print, see "Replacing Ink Tanks" on page 35.
If the problem remains, make sure that ink remains in the ink tank, turn off the printer's power for at
least 24 hours, and then perform deep cleaning of the print head again.
If the problem still remains, the print head may be damaged. Contact your local Canon service
representative.
