Some of the units ship with a different baud rate. Try changing the baud rate in the sketch to 9600.

Have you tested it with the SFGDemo utility? That checks a bunch of different rates and reports the speed that it connected at.

It's linked from the 'Downloads' page of the Fingerprint Sensor Tutorial, but here's a copy for convenience:
