• Code: C6756
• Description: CCD power-supply voltage malfunction. Power is not supplied to CCD after the lapse of a given period of time after the main power switch or power key is turned ON or the machine recovers from the sleep mode.
• Causes: • Scanner unit • DC power supply (DCPS) • MFP board (MFPB)
• Remedy: 1. Correct the harness connection between the scanner unit-MFPB CN103 if faulty. 2. Correct the harness connection between MFPB CN3E-DCPS CN5 if faulty. 3. MFPB ICP9 conduction check 4. Replace MFPB. 5. Replace the scanner unit. 6. Replace DCPS.

• Code: C6F01
• Description: Scanner sequence trouble 1. The original transport interval becomes shorter than the predetermined value due to an original transport control error in original reading in ADF.
• Causes: • MFP board (MFPB) • DF drive board (DFDB)
• Remedy: 1. Correct the harness connection between MFPB CN800E-DFDB J1 if faulty. 2. Replace DFDB. 3. Replace MFPB.

• Code: C8401
• Description: Data flash failure Data flash does not access normally.
• Causes: DF drive board (DFDB)
• 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. Check the DFDB connector for proper connection and correct as necessary. 3. Rewrite the firmware. 4. Replace DFDB.

• Code: C9401
• Description: Exposure lamp lighting failure detected. The output from the CCD sensor is a predetermined value or less during CCD sensor gain adjustment.
• Causes: • Scanner unit • MFP board (MFPB)
• Remedy: 1. Check the connector between scanner unit-MFPB CN23, CN103 for proper connection and correct as necessary. 2. Check for possible extraneous light and correct as necessary. 3. Clean the lens, mirrors, CCD surface, and shading sheet if dirty. 4. Replace the scanner unit. 5. MFPB ICP7, PTC802E conduction check 6. Replace MFPB.

• Code: C9402
• Description: Exposure LED lighting abnormally. The average output value of the CCD sensor with the scanner at its standby position is a predetermined value or more at the end of a scan job.
• Causes: • Scanner unit • MFP board (MFPB)
• Remedy: 1. Check the connector between scanner unit-MFPB CN23, CN103 for proper connection and correct as necessary. 2. Check for possible extraneous light and correct as necessary. 3. Clean the lens, mirrors, CCD surface, and shading sheet if dirty. 4. Replace the scanner unit. 5. MFPB ICP7, PTC802E conduction check 6. Replace MFPB.

• Code: CA051, CA052, CA053
• Description: • CA051: Standard controller configuration failure • CA052: Controller hardware error • CA053: Controller start failure. Trouble detection condition • CA051: The controller of the MFP board (MFPB) is faulty. • CA052: A controller hardware error is detected in the network interface. • CA053: A controller start failure is detected in the controller interface.
• Causes: MFP board (MFPB)
• Remedy: 1. Check the connectors of the MFPB for proper connection and correct as necessary. 2. Replace MFPB.

• Code: CC002
• Description: Vendor internal error. Error occurs inside the vendor.
• Causes: • Vendor • 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. Turn OFF and ON the power switch at the vendor side. 2. Check the connector between the vendor-MFPB CN16 for proper connection and correct as necessary. 3. Replace MFPB. 4. Replace the vendor.

• Code: CC140
• Description: Trouble related to security.
• Causes:
• Remedy: • Contact the responsible people of KM before taking some countermeasures.
