• Code: CA10
• Description: Laser optical unit related service call. Polygonal motor abnormality: The polygonal motor is not rotating normally.
• Causes: MAIN board Laser optical unit
• Remedy: 1 Is the polygonal motor rotating? Yes 1. Check if the conductor pattern on the MAIN board is short circuited or open circuited. 2. Replace the MAIN board. 3. Replace the laser optical unit. No 1. Check if the connector of the harness is disconnected between MAIN board (CN32) and the laser optical unit. Reconnect it securely if so. Even if the connector is not apparently disconnected, it may be connected loosely. Therefore check carefully that it is secure. 2. Check if the harness is open circuited and the connector pin is disconnected. 3. Check if the conductor pattern on the MAIN board is short circuited or open circuited. 4. Replace the laser optical unit. 5. Replace the MAIN board.
