• If nozzle check pattern is not printed correctly:
After performing the print head cleaning, print the nozzle check pattern and examine the pattern.
• If problem is not resolved after performing print head cleaning twice:
Perform print head deep cleaning.
• If problem is not resolved after performing print head deep cleaning:

■ For Mac OS:

To perform system cleaning, press and hold the Stop button until the Alarm lamp flashes 5 times, and
then release the button.

• Before performing system cleaning, check the remaining ink level of all colors. If the remaining ink
level is below the single dot (a), refill the ink tank of corresponding color. Performing system
cleaning when the remaining ink level is not enough may damage the machine.
If the problem is not resolved yet, the print head may be damaged. Contact your nearest Canon service
center to request a repair.
Important
• Do not tilt the machine when moving it since the ink may leak out.
