Beckman coulter field service engineer (fse) evaluated the automate instrument, and re-enacted the location of the customer's hand at the time of the injury in the tube supply unit whilst the instrument was powered down.The fse determined that a tube blockage in this section of the automate was attempted to be recovered whilst the system was still powered on and active.When the operator identified that a tube jam occurred in the inlet section of the tube hopper, the compressor was still under pressure and the piston still exerting a force on the tube.The automate ifu indicates to depressurize the compressor first and raises a warning "do not try to remove any tube jammed without depressurizing the compressor first." the cause of this issue is attributed to use error as the operator did not respect the prescribed instruction to depressurize the compressor while attempting to remove the jammed tube and the piston, now free from resisting obstacle, trapped the finger of the user.No further details were provided on the customer's injury.Initial reporter telephone number is (b)(6).The beckman coulter internal identifier is (b)(4).
