Check if the mounted parts on the SYS board are damaged or abnormal. 3. Check if the power is output. 3 SYS board 1. Check if the supply cable is connected properly to the connector (CN105). 2. Check if the mounted parts on the SYS board are damaged or abnormal. Exposure lamp 1. Check if the harness of the exposure lamp is connected to the LED light source properly. (CN123, CN010) 2. Check if the exposure lamp is scratched or damaged. 3. Check if the exposure lamp harness comes off the board. Power supply harness 1. Check if wiring of the power supply harness (CN105) is abnormal. 2. Check if the harness is scratched or open circuited.
  • Code: C261
  • Description:Peak detection error (high-light intensity)
  • Causes:Exposure lamp SYS board
  • Remedy:1 Exposure lamp 1. Replace the exposure lamp. 2 SYS board 1. Check if there is any abnormality in the appearance of the LED driver IC. (IC33) 2. Replace the SYS board. 3 Reflector 1. Check if there is any abnormality in the appearance of the reflector, such as deformation. 2. Replace the carriage-1.
  • Code: C262
  • Description:Peak detection error (communication error)
  • Causes:Lens unit SYS board Harnesses
  • 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 harness. 3. Replace the harness between the SYS board and the CCD board.
  • Code: C270
  • Description:Carriage home position sensor not going OFF within a specified time / Downloading firmware with an incorrect model
  • Causes:CCD board Carriage home position sensor Carriage home position sensor harness SYS board Scan motor Scan motor harness
  • 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 ¡E Check if the connector pin is disconnected or the harness is short circuited or open circuited. (CN001) ¡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. (CN121, J002) 2. Check if the harness is caught or open circuited. 5 SYS board 1. Check if the connector of the SYS board (CN120, CN121, CN124, CN105) is connected properly. 2. Check if the mounted parts on the SYS board are damaged or abnormal. 3. Check if 24 V (CN105) on the SYS board is short circuited. 4.
