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. 3. Replace the harness between the SYS board and the CCD board.
4 RADF/DSDF 1. 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. 2. 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. 3. Replace the communication cable between the RADF/DSDF and the equipment. 4. 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

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.
