SC842- C Number of Nand-Flash block deletions exceeded
02
At startup, or when the machined returned from energy save mode, the Nand-
Flash was read and judged that the number of deleted blocks had exceeded the
threshold, and then SCS generated this SC code.
Number of blocks deleted exceeded threshold for Nand-Flash.
Replace the controller board (PCB15).

When updating the firmware automatically (ARFU), the firmware cannot be read or
written normally, and the firmware update cannot be completed even by 3 retries.
Hardware abnormality of the target board
Replace the target board.
For SC845-02, HDD and memory may cause the problem. Replace the HDD or
memory if the SC cannot be recovered by replacing the controller board (PCB15).
No. Type
SC845- D DMM or hard disk failure

This SC occurs if auto firmware decompression fails after downloading the
package firmware during auto firmware update or receiving reservation setting in
SFU.
The machine operates normally if you turn the main power off and then back on,
but the SC occurs again when firmware decompression fails again during the next
auto firmware update.
