• Code: CC155
• Description: Finisher ROM error (When FS-533, FS-534, FS-534SD or JS-506 is installed). Data of flash ROM of the finishing options is determined to be faulty when the main power switch is turned ON.
• Causes: <When FS-533, FS-534 or FS-534SD is installed> • FS control board (FSCB) <When JS-506 is installed> • JS control board (JSCB)
• Remedy: When FS-533, FS-534 or FS-534SD is installed 1. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2. Rewrite the firmware. 3. Replace FSCB. (FS-533/FS-534/FS-534SD) When JS-506 is installed 1. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2. Rewrite the firmware. 3. Replace JSCB.

• Code: CC156
• Description: DF ROM error (When DF-629 or DF-704 is installed). Upgrade of the firmware has not been successful.
• Causes: DF control board (DFCB)
• Remedy: 1. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2. Rewrite the firmware. 3. Replace DFCB. (DF-629/DF-704)

• Code: CC159, CC15A
• Description: • CC159: ROM contents error upon startup (DSC1) • CC15A: 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/1 (DSCB/1; SC-508) • DSC board/2 (DSCB/2; SC-508: only when DF-704 is installed)
• Remedy: 1. Check DSCB/1 or DSCB/2 connector for proper connection and correct as necessary. 2. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 3. Rewrite the firmware. 4. Replace DSCB/1 or DSCB/2.

• Code: CC15B
• Description: Flash ROM error (saddle) (When FS-534SD is installed). Data of flash ROM of the saddle is determined to be faulty when the main power switch is turned ON.
• Causes: SD drive board (SDDB)
• Remedy: 1. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2. Rewrite the firmware. 3. Replace SDDB.

• Code: CC15C
• Description: Engine Flash ROM writing error. Data of flash ROM of the engine is determined to be faulty.
• Causes: MFP board (MFPB)
• Remedy: 1. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2. Rewrite the firmware. 3. Replace MFPB.

• 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: • EEPROM/1 • EEPROM/2 • MFP board (MFPB)
• Remedy: 1. Rewrite the firmware. 2. Replace MFPB NOTE • When taking the above steps, check whether MFPB is defective or not without replacing the EEPROM. 1. Turn OFF the main power switch and replace the current MFPB with a new one. 2. Update the 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 MFPB to the original board. 3. If the above actions do not solve the problem, contact KM.
