• Code: CC157
• Description: Finisher ROM error (RU) • When a communication error is detected between the main body and the horizontal transport unit.
• Causes: Transport control board (TRCB) FS control board (FSCB)
• Remedy: 1 Disconnect and then connect the power cord. Turn OFF the main power switch, wait for 10 sec. or more, and turn ON the main power switch. 2 Rewrite the firmware. 3 Change TRCB 4 Change DFCB

• Code: CC158
• Description: Finisher ROM error (ZU) • Data of flash ROM of the z-folding unit is determined to be faulty when the power is turned ON.
• Causes: ZU control board (ZUCB)
• Remedy: 1 Disconnect and then connect the power cord. Turn OFF the main power switch, wait for 10 sec. or more, and turn ON the main power switch. 2 Rewrite the firmware. 3 Change ZUCB

• Code: CC159
• Description: ROM contents error upon startup (DSC1) • A fault is detected in a sequence of ROM contents check of the DSC board during starting.
• Causes: DSC board (SC-507)
• Remedy: 1 Check the DSC board connector for proper connection and correct as necessary. 2 Disconnect and then connect the power cord. Turn OFF the main power switch, wait for 10 sec. or more, and turn ON the main power switch. 3 Rewrite the firmware. 4 Change DSC board

• Code: CC15A
• Description: ROM contents error upon startup (DSC2) • A fault is detected in a sequence of ROM contents check of the DSC board during starting.
• Causes: DSC board (SC-507)
• Remedy: 1 Check the DSC board connector for proper connection and correct as necessary. 2 Disconnect and then connect the power cord. Turn OFF the main power switch, wait for 10 sec. or more, and turn ON the main power switch. 3 Rewrite the firmware. 4 Change DSC board

• Code: CC15B
• Description: Finisher ROM error (SD) • Data of flash ROM of the saddle unit is determined to be faulty when the power is turned ON.
• Causes: SD drive board (SDDB)
• Remedy: 1 Disconnect and then connect the power cord. Turn OFF the main power switch, wait for 10 sec. or more, and turn ON the main power switch. 2 Rewrite the firmware. 3 Change SDDB

• Code: CC163
• Description: ROM contents error (PRT) • The wrong model of firmware is detected in the engine during the initial connection to the engine is being checked.
• Causes: Service EEPROM board (SV ERB) Printer control board (PRCB)
• Remedy: 1 Rewrite the firmware. 2 Change PRCB 1. Turn OFF the main power switch and replace the current PRCB with a new one. (When using a PRCB of another machine in service, be sure to use a PRCB installed in the same model.) 131 2. Update the PRCB firmware. 3. After completing the firmware update, turn OFF and ON the main power switch and check to see that warm-up is started. 4. When the trouble cannot be solved, reinstall the removed PRCB to the original board. NOTE • When taking the above steps, check whether PRCB is defective or not without replacing the SV ERB. 3 Change SV ERB 1. Replace the current SV ERB with a new one. 139 2. Turn ON the main power switch and check to see that warm-up is started. (One minute is spent to prepare the new SV ERB for use. During the period, the control panel backlight stays off.) 3. Make the specified readjustments. 139 4 If the above actions do not solve the problem, contact KMBT.

• Code: CC164
• Description: ROM contents error (MSC) • The wrong model of firmware is detected in the MFP board when the main power switch is turned ON.
• Causes: Printer control board (PRCB) MFP board (MFPB)
• Remedy: 1 Check the ROM version. 2 Rewrite the firmware. 3 Replace the corresponding board. 4 When not reviving even if the above-mentioned procedure is done, contact the responsible people of KMBT.

• Code: CC165
• Description: ROM contents error (ADF) • When the power is turned ON, DF control board or firmware error is detected.
• Causes: DF control board (DFCB)
• Remedy: 1 Disconnect and then connect the power cord. Turn OFF the main power switch, wait for 10 sec. or more, and turn ON the main power switch. 2 Rewrite the firmware. 3 Change DFCB
