Dotty IWB


If your IWB displays gaps when you are writing or drawing or sections don’t seem to respond to the pen then the most likely cause is dust on the camera (situated at each corner of the screen) or on the reflective strip that runs around the perimeter of the board.

Using a lint free cloth clean the cameras and the reflective strip that surrounds the IWB.


Items attached to the outside of the board or blocking the camera or reflective strip can also prevent the pen from working.
