I have the same machine. One time I got the error, "Mechanical Reels Not Configured" and "Mechanical Reels Device Error". The problem turned out to be the 'Reel Driver Optic Board' (P/N AS-03356-0527) on one of the reel assemblies. I pulled the reel giving me the problem and looked at the traces on the circuit board. They were burned. Replacing the board corrected the problem. You may or may not have this same problem, but it can cause this error message. Also, I have had USB cables go bad. Twice, simply replacing a USB cable fixed a problem.
