Since you checked and found no paper jam, please try performing a reset of the printer. While the printer is on, unplug the power cord from the printer. While the power is off, press the power button 5 times. After 60 seconds plug the power cord back in and power on the printer.
If the issue persists, I recommend reaching out to Canon support for this issue. You will need to register your Canon gear HERE to access additional support options.
We look forward to hearing from you.
