fingerprint Scanner-TTL (GT-511C3) message issue

Projects General Guidance

I am having difficulty setting up my fingerprint Scanner - TTL (GT-511C3). I have bought it from http://www.w11stop.com/manufacturer-sparkfun I'm using the library from https://github.com/sparkfun/Fingerprint_Scanner-TTL/tree/master/FPS_GT511C3 and none of the example sketches work.

I have a message printing to the serial before the fps.open() command and a message printing afterwards, but I only ever see the first message. Does this mean the arduino is stuck trying to open the scanner?
Please Help me out.....!!!

Yes. My first guess would be a baud rate mismatch. My second would be bad wiring. My third would be a pin use conflict. My fourth would be a faulty fingerprint reader. My fifth would be a bad library and example sketches.
