This error is due to a transient communication issue that does not affect run progression or performance.
Possible error messages: "AsyncFirmwareOperationCommand timed out waiting for started after XX:XX:XX." "While waiting on an asynchronous firmware operation: camera bitmask 111111 Originally caused by: Failed XY Stage."
Troubleshooting steps:
If the run is continuing, allow the run to complete and monitor.
After the run completes, review run performance. See Specifications for the NextSeq 500/550 System.
Power cycle NextSeq 500/550.\*
If the system initializes, proceed with the next sequencing run.
If the same notification is displayed over 2-3 consecutive runs, contact Illumina Technical Support, for further assistance.
