Cleaning the Proximity Sensor Cavities
The SelfCheck system uses proximity sensors installed in the book cradle to
determine when a book has been placed on the cradle. If the proximity
sensor cavities become blocked with dirt and debris, the proximity sensors
may not work properly. Clean the proximity sensor cavities as needed.
