• 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 PS201, M201, REYB/SCAN and IPB connector for proper connection and correct as necessary. 5 PS201 I/O check, sensor check IPB CN11IPB-3 (ON) T-15 6 M201 operation check REYB/SCAN CN5REYB/SCAN-4 to 7 Q to R-18. 7 Change REYB/SCAN. 8 Change IPB.

• 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 prescan 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 PS201, M201, REYB/SCAN and IPB connector for proper connection and correct as necessary. 5 PS201 I/O check, sensor check IPB CN11IPB-3 (ON) T-15 6 M201 operation check REYB/SCAN CN5REYB/SCAN-4 to 7 Q to R-18. 7 Change REYB/SCAN. 8 Change IPB.

• Code: C6301
• Description: Optical cooling fan motor’s failure to turn
  • The fan lock signal remains HIGH for a predetermined continuous period of time while the motor remains stationary.
• Remedy: 1 Check the FM201 connector for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 M202 operation check REYB/SCAN CN2REYB/SCAN-3 (LOCK) Q to R-18. 4 Change REYB/SCAN. 5 Change IPB.

• Code: C6704
• Description: Image input time out
  • Image data is not input from the image processing board (IPB) to the printer control board (PRCB).
• 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 IPB and MFPB for proper connection and correct as necessary. 3 Change MFPB. 4 Change IPB.
