• Code: C6102
• Description: Drive system home sensor malfunction
  • The scanner home sensor is unable to detect the scanner located at its home position. • The scanner home sensor is unable to detect a scanner even when the scanner motor has been driven to move the scanner over the maximum travelling distance. • The scanner home sensor detects the scanner when the scanner has moved the maximum travelling distance from the position, at which it blocks the scanner home sensor.
• Remedy: 1 Correct or change the scanner drive (cable, pulley, gear, belt) if it is faulty. 2 Correct the scanner motor set screw if loose. 3 Adjust [Image Position Leading Edge] and [Feed Direction Adjustment]. 4 Check the connector between M201- REYB/SCAN PJ5 for proper connection and correct as necessary. 5 Check the connector between PS201- REYB/SCAN PJ8 for proper connection and correct as necessary. 6 Check the connector between REYB/ SCAN PJ2-MFPB PJ14 for proper connection and correct as necessary. 7 PS201 I/O check, sensor check REYB/SCAN PJ8-3 (ON) T-9 8 M201 operation check REYB/SCAN PJ5-1 to 4 T-12. 9 Change REYB/SCAN. 10 Change MFPB.

• Code: C6103
• Description: Slider over running
  • The scanner home sensor detects the scanner at its home position during a period of time that begins with the time when a pre-scan command and a scan preparation command are executed and ends when a home return command is executed.
• Remedy: 1 Correct or change the scanner drive (cable, pulley, gear, belt) if it is faulty. 2 Correct the scanner motor set screw if loose. 3 Adjust [Image Position Leading Edge] and [Feed Direction Adjustment]. 4 Check the connector between M201- REYB/SCAN PJ5 for proper connection and correct as necessary. 5 Check the connector between PS201- REYB/SCAN PJ8 for proper connection and correct as necessary. 6 Check the connector between REYB/ SCAN PJ2-MFPB PJ14 for proper connection and correct as necessary. 7 PS201 I/O check, sensor check REYB/SCAN PJ8-3 (ON) T-9 8 M201 operation check REYB/SCAN PJ5-1 to 4 T-12. 9 Change REYB/SCAN. 10 Change MFPB.

• Code: C6704
• Description: Image input time out
  • Image data is not input from the CCD board (CCDB) to the MFP board (MFPB).
• Remedy: 1 Select [Service Mode] - [State Confirmation] - [Memory/HDD Adj.] - [Memory Bus Check] ?? [Scanner??Memory], and conduct the memory bus function. 2 Check the connectors between scanner section and MFPB for proper connection and correct as necessary. 3 Change MFPB. 4 Change CCDB.

• Code: C6751
• Description: CCD clamp/gain adjustment failure
  • The adjustment value is 0 or 255 during a CCD clamp adjustment. • The peak value of the output data is 64 or less during a CCD gain adjustment.
• Remedy: 1 Check the connector between CCDB PJ2- MFPB PJ01 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 Correct reflective mirror of the scanner if faulty, or change scanner. 5 Change CCDB. 6 Change MFPB.

• Code: C6752
• Description: ASIC clock input error (front side)
  • When starting the scanner, verification on reading and writing the predetermined value for image processing ASIC on CCD board was conducted, and verification failure was detected.
• Remedy: 1 Correct the harness connection of CCDB if faulty. 2 Change CCDB. 3 PRCB ICP11 conduction check. 4 Change PRCB. 5 Change MFPB.

• Code: C6753
• Description: ASIC clock input error (back side)
  • When starting the scanner, verification on reading and writing the predetermined value for image processing ASIC on CCD board was conducted, and verification failure was detected.
• Remedy: 1 Correct the harness connection of CCDB if faulty. 2 Change CCDB. 3 PRCB ICP11 conduction check. 4 Change PRCB. 5 Change MFPB.

• Code: C6901
• Description: DSC board mount failure 1
  • When MFP detects that DSC board is not properly installed.
• Remedy: 1 Correct the harness connection of DSC board if faulty. 2 Change DSC board. 3 Change MFPB.

• Code: C6902
• Description: DSC Bus check NG1-1
  • When DSC bus check detects an error.
• Remedy: 1 Correct the harness connection of DSC board if faulty. 2 Change DSC board. 3 Change MFPB.
