The stack of plates in the cassette is higher than the cassette lip, preventing the MCU from reaching the pick position sensor.
To correct the error:
Click Release to reinitialize the system.
Load the cassette that had the error. See Loading and Imaging Media in the operator
guide.
CAUTION: Wear
protective gloves when handling plates. Plate edges can be sharp. Failure
to wear protective gloves can result in injury.
