Remedy: • Replace the PCB • Replace the short-circuited part (harness, motor, solenoid)
Code: SC791-00
Description: No Bridge Unit when Finisher is Present. When power supply is switched on or paper is transported, finisher set is detected but bridge unit set is not detected. (during internal finisher connection, not detected)
Causes: • Bridge unit not attached • Bridge unit defective
Remedy: • Reset the bridge unit • Turn the power off/on
Code: SC792-00
Description: No Finisher, Bridge Unit Provided When a machine which has a bridge unit is powered on, no finisher is detected
Causes: • Finisher connector set fault • In a machine which has a bridge unit connected, a finisher is not fitted • Finisher defective
Remedy: Connect finisher or disconnect bridge unit, and turn the power off/on
Code: SC816
Description: Energy save I/O subsystem error
Causes: • Energy save I/O subsystem defective • Energy save I/O subsystem detected a controller board error (non-response). • Error was detected during preparation for transition to STR.
Remedy: • Turn the main power off/on. • Replace the controller board.
Code: SC817-00
Description: Monitor error: File detection / Digital signature error • Bootloader cannot read any of diagnostic module, kernel, or root filesystem. • In a bootloader SD card, the digital signature cheking for any of diagnostic module, kernel, or root filesystem is failed.
Causes: • Any of the following items does not exist or is broken: OS Flash ROM, Diagnostic module in SD card, Kernel, Root filesystem • Any of the following items is revised fraudulently: Diagnostic module in SD card, Kernel, Root filesystem
Remedy: • ROM update for controller system • Use another booting SD card having a valid digital signature
Code: SC818-00
Description: Watchdog timer error The system program fell into a bus-hold state or an endless loop of the program interruption occurred, causing other process to stop.
Causes: • System program defective • Controller board defective • Optional board defective
Remedy: • Turn the main power off/on. • Replace the controller board.
