Fuji XG5000

I traveled to Athens today to address a problem they were having with Fuji XG5000 CR reader. They were reporting that slot #3 would not work and slot #2 was having problems returning the IP plate back into the cassette. When we arrived, we tested the unit and found all slots working as they should. After checking the error log, we found multiple errors pointing to the SZ2 sensor on the drive shaft at the bottom left section of the unit. We changed the sensor just as a precaution, even though the reader seemed to be working properly. We tested all the slots again and found them to be working properly. Then we checked the error log again and found no more errors.
