I'm impressed with your problem pursuit measures, Zoltan - you have tried quite a lot. If your CE is stumped...
I presume that the drive's panel indicates a neutral drive state, rather than any indication of cleaning. (I would not want to see a situation where the OS was for some reason persistently forcing the drive to cleaning mode.)
Whereas the drive has been reset and power-cycled, it ostensibly doesn't think that it is in Cleaning mode; but the library still does. This might indicate a problem in communication between library and drive, which occurs over the ARTIC manifold of RS-422 cabling...which might be as simple as a loose connection, or may be a fault in some of the electronics. The CE should be able to watch the 3494's internal logs as you perform actions like reset and power cycling on the drive, to see if communication is happening - particularly comparing its behavior with that of the other drives. If the communication is all happening correctly, then something may be awry in the library database. I would try to jog state by making the drive Unavailable then Available at the 3494 operator panel. An experienced CE should be able to track this down.
