• Causes: • Glass cleaning motor (M4) • Original reading glass cleaning sensor (PS12) • DF control board (DFCB)
• Remedy: 1. Check the connector between M4-DFCB J8 for proper connection and correct as necessary. 2. Check the connector of M4 for proper drive coupling and correct as necessary. 3. Check the connector between PS12-DFCB J15 for proper connection and correct as necessary. 4. PS12 I/O check, sensor check • Control signal: DFCB J15-5 (ON) • Location of electrical component: DF-628 3-G 5. M4 operation check • Control signal: DFCB J8-1 to 4 • Location of electrical component: DF-628 1 to 2-B 6. Replace M4. 7. Replace DFCB.

• Code: C8401
• Description: Data flash failure (When DF-628 is installed). Data flash does not access normally.
• 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. Check the DFCB connector for proper connection and correct as necessary. 3. Rewrite the firmware. 4. Replace DFCB.

• Code: C9401
• Description: Exposure LED lighting failure. The output from the CCD sensor is a predetermined value or less during CCD sensor gain adjustment.
• Causes: • LED exposure unit • CCD unit • Flat cable (CCD unit) • CCD board (CCDB) • MFP board (MFPB)
• Remedy: 1. Check the connector between LEDB CN1-CCDB PJ7 for proper connection and correct as necessary. 2. Check the connector between CCDB PJ1-MFPB CN7 for proper connection and correct as necessary. 3. Replace the LED exposure unit. 4. Replace the CCD unit. 5. MFPB F8E 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: • LED exposure unit • CCD unit • Flat cable (CCD unit) • CCD board (CCDB) • MFP board (MFPB)
• Remedy: 1. Check the connector between LEDB CN1-CCDB PJ7 for proper connection and correct as necessary. 2. Check the connector between CCDB PJ1-MFPB CN7 for proper connection and correct as necessary. 3. Replace the LED exposure unit. 4. Replace the CCD unit. 5. MFPB F8E conduction check 6. Replace MFPB.

• Code: CA051
• Description: Standard controller configuration failure. The controller of the MFP board (MFPB) is faulty.
• Causes: MFP board (MFPB)
• Remedy: 1. Check to see if [Service Mode] -> [System 2] -> [Image Controller Setting] has been set to “Controller 0.” If changing the setting, turn OFF the main power switch and turn it ON again after 10 seconds or more. 2. Check the connectors of the MFPB for proper connection and correct as necessary. 3. Replace MFPB.

• Code: CA052
• Description: Controller hardware error. A controller hardware error is detected in the network interface.
• Causes: MFP board (MFPB)
• Remedy: 1. Check to see if [Service Mode] -> [System 2] -> [Image Controller Setting] has been set to “Controller 0.” If changing the setting, turn OFF the main power switch and turn it ON again after 10 seconds or more. 2. Check the connectors of the MFPB for proper connection and correct as necessary. 3. Replace MFPB.

• Code: CA053
• Description: Controller start failure. A controller start failure is detected in the controller interface.
• Causes: MFP board (MFPB)
• Remedy: 1. Check to see if [Service Mode] -> [System 2] -> [Image Controller Setting] has been set to “Controller 0.” If changing the setting, turn OFF the main power switch and turn it ON again after 10 seconds or more. 2. Check the connectors of the MFPB for proper connection and correct as necessary. 3. Replace MFPB.
