Greetings,
Remove and reseat the ink cartridges. Then retest. If the behavior continues, the printhead is likely damaged due to overheating or other issue.
The printer has a 1 yr warranty. However, it's approximately 10 years old now. You can register the printer in your MyCanon account to see your support options.
If the printer is out of warranty, I recommend replacing it.
