Yes Check if the circuits of the CCD board are abnormal. No 3 3 CCD board ¡E Check if the connector pin is disconnected or the harness is short circuited or open circuited. ¡E Check if the conductor pattern on the CCD board is short circuited or open circuited. ¡E 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 1. Check if the harness of the carriage home position sensor is connected properly. 2. Check if the harness is caught or open circuited. 5 SYS board 1. Check if the connector of the SYS board (CN121, CN124, CN125) is connected properly. 2. Check if the mounted parts on the SYS board are damaged or abnormal. 3. Check if 24 V (CN125) on the SYS board is short circuited. 4. Check if 24 V is supplied to the SYS board (CN125). 6 Scan motor 1. Check if the belt tension is loosened. 2. Check if the motor fixing screw is loosened. 3. Check if the carriage wire and the timing belt come off. 4. Check if the connector (CN124) is connected to the motor properly. 5. Check if the harness of the motor is caught or open circuited. 7 Setting Clear the SRAM data and initialize them. Refer to ƒt P. 9-24 "9.2.5 Precautions and procedure when replacing the SRAM".
