How fast did you swipe? Did you try fprint_demo to check the quality of fingerprint? > etes603:debug [process_remove_fp_end] Removing 498 empty lines from > image > etes603:debug [process_remove_fp_end] Removing 496 empty lines from > image Here the second fingerprint seems empty... Not sure what happened here. Is it easy to reproduce? I think the best way to find the problem is that you try fprint_demo and you send me debug output and resulted fingerprint images.
