• Code: CC155
• Description: Finisher ROM error <bizhub C3851FS> A finisher flash ROM writing sequence is interrupted in its mid-operation due to, for example, power being shut off.
• Causes: FS control board (FSCB)
• 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 FSCB.

• Code: CC163
• Description: Faulty destination • The wrong model of firmware is detected in the engine during the initial connection to the engine is being checked. • Hardware signal is not fixed when the Boot started.
• Causes: 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.

• 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: MFP board (MFPB)
• Remedy: 1. Check the ROM version. 2. Rewrite the firmware. 3. Replace MFPB. 4. If the above actions do not solve the problem, contact KM.

• Code: CC167
• Description: Finisher FW download communication fault (ENG detection) <bizhub C3851FS> A communication error is detected on the MFP board (MFPB) side during FW download communication between the MFP board (MFPB) and FS control board (FSCB).
• Causes: • FS control board (FSCB) • 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 FSCB. 4. Replace MFPB.

• Code: CC168
• Description: Finisher FW download communication fault (FNS detection) <bizhub C3851FS> A communication error is detected on the FS control board (FSCB) side during FW download communication between the MFP board (MFPB) and FS control board (FSCB).
• Causes: • FS control board (FSCB) • 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 FSCB. 4. Replace MFPB.

• Code: CC169
• Description: Finisher Flash ROM device error <bizhub C3851FS> An erase error or other device fault occurs during finisher flash ROM writing.
• Causes: FS control board (FSCB)
• 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 FSCB.

• Code: CC170 ... CC186
• Description: • CC170: Dynamic link error during starting (AP0) • CC171: Dynamic link error during starting (AP1) • CC172: Dynamic link error during starting (AP2) • CC173: Dynamic link error during starting (AP3) • CC174: Dynamic link error during starting (AP4) • CC180: Dynamic link error during starting (LDR) • CC181: Dynamic link error during starting (IBR) • CC182: Dynamic link error during starting (IID) • CC183: Dynamic link error during starting (IPF) • CC184: Dynamic link error during starting (IMY) • CC185: Dynamic link error during starting (SPF) • CC186: Dynamic link error during starting (OAP) Trouble detection condition A dynamic link error occurs in the program on the MFP board due to an insufficient memory space available, a ROM fault, or other reason when the main power switch is turned ON.
• Causes: MFP board (MFPB)
• Remedy: 1. If the malfunction code "C-C180" has occurred, check to install the appropriate loadable device driver for an authentication unit which is installed to the MFP. When the appropriate loadable device driver is not installed, reinstall the appropriate loadable device driver. 2. Replace MFPB. 3. If the above actions do not solve the problem, contact KM.
