  • Replace the controller board.

• Code: SC816-35
• Description: read() error
• Causes:
• Remedy: • Turn the main power off/on.
  • Replace the controller board.

• Code: SC816-36... SC816-94
• Description: Subsystem error
• Causes: Energy save I/O subsystem detected some abnormality. • Energy save I/O subsystem defective • Energy save I/O subsystem detected a controller board error (nonresponse). • Error was detected during preparation for transition to STR.
• Remedy: • Turn the main power off/on.
  • Replace the controller board.

• Code: SC818-00
• Description: Watchdog timer error
• Causes: • The system program fell into a bus-hold state or an endless loop of the program interruption occurred, causing other process to stop. • System program defective • Controller board defective • Optional board defective
• Remedy: • Turn the main power off/on. • Replace the controller board. • Replace the optional devices.

• Code: SC833-00
• Description: [0F31] Self-diagnostic error: Engine I/F ASIC Self-diagnostic error: Video I/F
• Causes: Engine I/F: ASIC register error The /CONFIG_DONE signal is not detected even after the specified time has elapsed after turning the power on or restoring from energy saver mode. Downloading of the Config data to FPGA has failed.
• Remedy: Replace the controller board.

• Code: SC833-00
• Description: [0F10] Fsync input timeout
• Causes: After the /PRREQ signal is detected, the /FSYNC(/FGATE) signal of the first color is not detected even after the specified time has elapsed. Connector, harness defective FGATE control error EGB defective
• Remedy:

• Code: SC842-01
• Description: Nand-Flash bad block number exceeding the threshold
• Causes: When starting-up the machine or re-stating it from the energy saving, the machine reads the state of the NAND-Flash and detects that there are defective blocks whose amount exceeds the threshold. This means that the life of the NAND-Flash is near-end. Near-end Life of NAND-Flash
• Remedy: Replace the controller board as soon as possible.

• Code: SC850-00
• Description: Network I/F error
• Causes: The access to the network work is unavailable due to an error in the printer driver.
• Remedy:
