Type  | Storage Timing  | Destination (maximum storage capacity)  | 
|---|---|---|
Controller debug log (GW debug log)  | 
  | HDD (4 GB). Compressed when written to an SD card from the HDD (from 4 GB to about 300 MB)  | 
Engine debug log  | 
  | HDD (up to 300 times)  | 
Operation panel debug log  | 
  | Operation panel (400 MB /Up to 30 times) When updating the firmware for the operation panel, the debug logs are erased.  | 
Debug logs are not saved when:
- Memory is being erased
 - Data encryption equipment is being installed
 - Firmware configuration is being changed
 - There is a power outage (power cord disconnected accidentally)
 - The machine is shutdown normally with the power switch and data write to the HDD cannot be completed. For example, when shutdown starts immediately after a paper jam occurs or the front door is opened or closed, the machine needs about 5 sec. to save the debug log after the machine stops completely.
 - Power supply to the HDD is off because of energy saving (engine OFF mode /STR mode)
