Really, that is all we get to go on? It is very difficult to help when we know so little about your project. We need specific information about the "scanner" and the library. We need to know how the scanner is connected to the Arduino (schematic). Also we will need to see your code.
PLEASE read the "how to use the forum-please read" stickies to see how to format and post code. Also there are some good hints on how to ask an effective question.
