Now the POWER lamp starts flashing and print head deep cleaning begins. The process
takes one or two minutes to complete, so simply wait until the POWER lamp stops flashing.
After print head deep cleaning finishes, print the nozzle check pattern to verify that the head
is clean. If the print head is still not clean, repeat print head deep cleaning and the nozzle
check pattern printing up to three times. If the problem persists, the print head may be worn
out. Contact a Canon service representative.
