• Code: CD701, CD702, CD703
• Description: • CD701: Mechanical controller flash ROM writing error • CD702: Mechanical controller flash ROM device error • CD703: FW download communication fault. CD701: A mechanical controller flash ROM writing sequence is interrupted in its mid-operation due to, for example, power being shut off. CD702: An erase error or other device fault occurs during mechanical controller flash ROM writing. CD703: Irregular data is received during FW downloading. • Places are changed in the order of write completion pulses. • A write completion pulse is received for a memory for which binary writing is not permitted. • Final checksum mismatch in FW download • Two-minute timeout (no response from CTL, the number of transfer data items less than the specified)
• 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.

• 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: CD705, CD706
• Description: • CD705: Mechanical controller sub-CPU flash ROM device error • CD706: Mechanical controller sub-CPU flash ROM error. • CD705: An erase error or other device fault occurs during mechanical controller sub-CPU flash ROM writing. • CD706: A data error is determined to exist in the mechanical controller sub-CPU flash ROM during starting.
• 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: CDF50, CDF70, CDFA0
• Description: • CDF50: ASIC image version failure • CDF70: ASIC image access failure • CDFA0: ASIC image error. Communication error is detected between the MFP board (MFPB) and the CCD board (CCDB).
• Causes: • CCD unit • MFP board (MFPB) • CCD board (CCDB)
• Remedy: 1. Check the connector between MFPB CN7-CCDB PJ1 for proper connection and correct as necessary. 2. Rewrite the firmware. 3. Replace the CCD unit. 4. Replace MFPB.

• Code: CE001, CE003, CE004
• Description: • CE001: Abnormal message queue • CE003: Task error • CE004: Event error. MFP board (MFPB) is faulty.
