SC2xx: Exposure
D0CA/D0C9/D0C8/D0CB 6-18 SM
No. Type Details (Symptom, Possible Cause, Troubleshooting Procedures)
SC231-01 D FGATE OFF Error: K
SC231-02 D FGATE OFF Error: C
SC231-03 D FGATE OFF Error: M
SC231-04 D FGATE OFF Error: Y
FGATE signal is not OFF even when the laser is ready to end.
This SC is detected when the machine is copying.
• Connection error between BiCU (PCB1) and Controller
• BiCU failure (Damaged laser ASIC)
1. Cycle the power OFF/ON.
2. Check the connection between BiCU (PCB1) and Controller Board
(PCB24).
3. Replace the BiCU (PCB1).

SC240-01 D LD Error: K
SC240-02 D LD Error: C
SC240-03 D LD Error: M
SC240-04 D LD Error: Y
• The LD current is more than the prescribed current during emitting light.
• LD driver cannot be initialized correctly.
• Disconnected LDB harness.
This SC is detected when:
• The machine starts up.
• The machine is copying.
• LDB harness connection error
• Deteriorated LD (LD broken)
• LDB (Laser unit) failure
• LDB harness failure
1. Cycle the power OFF/ON.
2. Check the value in SP2-110-001 to 004 (LD Driver).
• If current value is "0", perform step 3.
• If current value is "1", perform steps 3 and 5.
• If current value is "2" to "FF", perform step 4.
3. Reconnect the connectors between LDB and BICU (PCB1).
4. Replace the Laser unit.
5. Replace the harness between LDB and BiCU (PCB1).
