Code :

Code: SC674-02
Description: Transfer error: PCI The video transfer error has occurred on the controller board. A PCI error interrupt is generated by the expanded engine ASIC (SELENE, SELENE2). The expanded engine ASIC has failed in its attempt to access another PCI device. The PCI error may occur simultaneously with the M2P error (SC674-01). If this happens, the PCI error takes priority when the SC is displayed.
Causes: • Defective Controller Board/software
Remedy: • Turn the main power off/on.

Code: SC681
Description: Device ID is not identified (toner cartridge) An error is notified during the ID identification after three retries.
Causes: 681 - 1 Device ID error (Incorrect ID) 681 - 6 Channel error 681 - 11 Device ID error (No ID chip) 681 - 16 Communication Error 681 - 21 Communication timeout 681 - 26 The device has stopped its operation 681 - 31 The requested buffer is full 681 - 36 EEPROM SRAM OPEN: Verification error
Remedy: • Turn the main power off/on. • Replace the toner cartridge (ID chip error)

Code: SC682
Description: Device ID is not identified (PCDU) An error is notified during the ID identification after three retries.
Causes: 682 - 1 Device ID error (Incorrect ID) 682 - 6 Channel error 682 - 11 Device ID error (No ID chip) 682 - 16 Communication Error 682 - 21 Communication timeout 682 - 26 The device has stopped its operation 682 - 31 The requested buffer is full 682 - 36 EEPROM SRAM OPEN: Verification error
Remedy: • Turn the main power off/on. • Replace the PCDU (ID chip error)

Code: SC687-00
Description: RAPI-PER receipt failure Even though 120 seconds have elapsed after RAPI -PES (request for image transfer) is issued, a RAPI-PER receipt is not received from the controller board.
Causes: • Defective controller board • Noise
Remedy: • Turn the main power off/on. • Replace the controller board.

Code: SC688-00
Description: PRREQ signal not asserted The print request signal (PRREQ) signal is not asserted within the prescribed time after paper reaches the registration stand-by position,
Causes: • Noise • Engine board error
Remedy: • Turn the main power off/on. • Replace the engine board.

Code: SC790-00
Description: Maximum number of banks (paper tray units) exceeded error When the main power is turned ON, the machine detects that more than three paper tray units are mounted.
Causes: The number of mounted paper tray units exceeds the specifications.
Remedy: Reduce the number of mounted paper tray units according to the specifications.

Code: SC816
Description: Energy save I/O subsystem error. Energy save I/O subsystem detected some abnormality.
Causes: • 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 • 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.
