# Troubleshooting RFID cannot be written error on the MiSeq
This error can appear during a run as the instrument checks the Radio-frequency Identification (RFID) sensors. It is usually caused by a temporary communication failure and will not stop a run nor affect data quality.
**Figure 1**: Error language can include "The FPGA reported an error while executing command "RFIDBLKWR 0 19 80000002"; error message: "RFID ERROR STATUS 2 A0000", "PR2RFIDSensor: Cannot write Run ID to RFID tag" or "FlowcellCartridgeRFIDSensor: Cannot write Run ID to RFID tag."\
**Troubleshooting Steps:**
1. Allow the run to continue.
2. Power cycle the MiSeq before next run.
For further information, search for Knowledge Base articles **How to Shut down or power cycle the MiSeq** and **How To Power Cycle the MiSeq Video.**
