How do I resolve the "User Intervention Required" message on my Canon printer? (Windows)
- At the same time, press the windows key and ‘r’ on your keyboard.
 - In the ‘Run’ box, type ‘services.msc’ then ‘OK.’
 - Within ‘Services,’ right-click on ‘Print Spooler.’
 - Press ‘Restart.’
 - Close this window and try printing.
 - If this is unsuccessful, turn off your printer.
