Users have complained about not being able to scan documents when the Canon Pixma MG5220 is out of ink. However, there is a way around this issue. All you have to do is reset the ink detection, and the scanner will work again.
- To reset the ink detection, simply press and hold “Stop” (button with orange circle and triangle) for 5 seconds. The Alarm should clear, and the printer will allow you to scan once again.
