'Unknown Error' with Adafruit fingerprint scanner

I just got an Adafruit fingerprint scanner but i’m getting an error when i run the enrol sketch. I downloaded the libraries from adafruit’s github and installed them. I uploaded the enrol sketch to my arduino but this happens when i try to enrol one of my fingers.
