Exposure lamp • Check if the connector is properly connected to the board of LED lamp unit. • Check if there are any scratches or damage on the board of LED lamp unit. • Replace the exposure lamp unit.
Harness • Check if wiring of the harness (CN125 on the SYS board) is abnormal. • Check if the harness (CN125 on the SYS board) has any scratch on it or is open circuited or caught anywhere. • Replace the harness (CN125 on the SYS board).
- Code: C262
- Description: Communication error
- Causes: Scanning system related service call Communication error between the CCD board and the SYS board
- Remedy: 1 Lens unit • Check if the connector is properly connected all the way in the CCD board. • Check if there is any abnormality in the appearance of parts mounted on the CCD board. • Check if +5V is output to the lens unit. • Check if the voltage is output from the CCD board. • Replace the Lens unit.
2 SYS board • Check if the connector is properly connected all the way in the SYS board. (CN120) • Check if there is any abnormality in the appearance of parts mounted on the SYS board. • Check if +5V is output to the SYS board. • Replace the SYS board.
3 Harnesses • Check if the harness has any scratch on it or is open circuited or caught anywhere. • Check if there is any abnormality in the connector terminal. • Replace the harness between the SYS board and the CCD board.
4 RADF/DSDF • Turn the power OFF, disconnect the communication cable of the RADF/DSDF from the equipment and turn the power ON again. Then check if the error is reproduced. • If the error is reproduced, check if there is any abnormality in the communication cable and the connector between the RADF/DSDF and the equipment. • Replace the communication cable between the RADF/DSDF and the equipment. • Replace the RADF/DSDF.
- Code: C270
- Description: Carriage home position sensor not turning OFF within a specified period of time/ Downloading firmware with an incorrect model
- Causes: Scanning system related service call Carriage home position sensor not turning OFF within a specified period of time/Downloading firmware with an incorrect model
- Remedy: 1 Carriage locking Check if the carriage locking screw for packaging is attached.
2 Are the carriages slightly moved to the feeding direction?/Are the carriages staying at a position other than home position? Yes Check if the circuits of the CCD board are abnormal. No 3
3 CCD board • Check if the connector pin is disconnected or the harness is short circuited or open circuited. (CN001) • Check if the conductor pattern on the CCD board is short circuited or open circuited. • If the model of the firmware downloaded is incorrect, a C270 error (exposure lamp blinks twice) occurs. If the exposure lamp blinks twice, download the correct firmware.
4 Carriage home position sensor • Check if the harness of the carriage home position sensor is connected properly. (CN121, J002) • Check if the harness is caught or open circuited.
5 SYS board • Check if the connector of the SYS board (CN120, CN121, CN124, CN105) is connected properly. • Check if the mounted parts on the SYS board are damaged or abnormal. • Check if 24 V (CN105) on the SYS board is short circuited. • Check if 24 V is supplied to the SYS board (CN105).
6 Scan motor • Check if the belt tension is loosened. • Check if the motor fixing screw is loosened. • Check if the carriage wire and the timing belt come off. • Check if the connector (CN124) is connected to the motor properly. • Check if the harness of the motor is caught or open circuited.
