Causes: Lens unit SYS board LED Supply harness
Remedy: 1 Does the exposure lamp lit? (Perform the output check: FS-03-267) Yes It is lit. 2 No It is not lit. 3 2 Shading correction plate Check if there is any scratch or stain on the shading correction plate. Mirror Check if the mirror is tilted. 1. Check that the lens is reflected in the mirror looking at carriage-1 from the upper position. 2. Check that the mirror is secured at the leaf spring. Carriage 1. Check if the carriage is tilted by moving it to the left stopping point. 2. Check if the wire fixing screw is loosened. 3. Check if the movement of the carriage is unstable due to disengagement of the carriage roller. LED 1. Check if the LED lamp is correctly lit. 2. Check if the harness is connected properly to the LED lamp connector. 3. When the carriage is driven, check if the harness interferes with it or parts are caught in it. CCD board / Lens unit 1. Check if the connector of the CCD board is connected properly. 2. Check if the CCD board is installed properly. (Check that the lens unit is not tilted or the screw is securely tighten.) SYS board 1. Check if the connector of the SYS board (CN120, CN123) is connected properly. 2. Check if the mounted parts on the SYS board are damaged or abnormal. 3. Check if the power is output from the SYS board for CCD. 3 SYS board 1. Check if the supply cable is connected properly to the connector (CN125). 2. Check if the mounted parts on the SYS board are damaged or abnormal. LED 1. Check if the harness of the lamp is connected to the LED light source properly. 2. Check if the lamp is scratched or damaged. 3. Check if the LED harness comes off the board. Supply harness 1. Check if wiring of the supply harness (CN125) is abnormal. 2. Check if the harness is scratched or open circuited.
Remedy: 1 Lens unit 1. Check if the connector is properly connected all the way in the CCD board. (CN001) 2. Check if there is any abnormality in the appearance of parts mounted on the CCD board. 3. Check if +5V is output to the CCD board. 4. Check if +3.3V is output from the CCD board. 5. Replace the Lens unit. 2 SYS board 1. Check if the connector is properly connected all the way in the SYS board. (CN120) 2. Check if there is any abnormality in the appearance of parts mounted on the SYS board. 3. Check if +5V is output to the SYS board. 4. Replace the SYS board. 3 Harnesses 1. Check if the harness has any scratch on it or is open circuited or caught anywhere. 2. Check if there is any abnormality in the connector terminal or the contacting surface of the flat cable. 3. Replace the harness between the SYS board and the CCD board.
