This error can occur if the decouplers in the Material Station are not calibrated. They have either been de-calibrated during transport, or calibration hasn't been performed yet. A decoupler calibration procedure must be performed.
If you have performed the calibration procedure, but the error still persists, it may be that you have a faulty UMBus cable. This is the cable that connects the Ultimaker S5 to the Material Station.
To resolve this error, please follow the decoupler calibration instructions outlined in this document.
