• Code: 220-01
• Description: Laser synchronizing detection error: start position LD1: Bk/C. Synchronizing detection signal cannot be received. This SC is detected when: • The machine starts up. • The machine is copying.
• Causes: • Defective LD unit (Synchronizing mechanism or LDB failure) • BiCU failure (Damaged laser ASIC) • Disconnected LDB harness
• Remedy: • Cycle the power off/on. • Check for condensation on the LDB. • Check the harness between LDB (Synchronizing mechanism) and BiCU. • Replace the LD unit. • Replace the BiCU. • Replace the harness between LDB and BiCU.

• Code: 220-03
• Description: Laser synchronizing detection error: start position LD1: M/Y. Synchronizing detection signal cannot be received. This SC is detected when: • The machine starts up. • The machine is copying.
• Causes: • Defective LD unit (Synchronizing mechanism or LDB failure) • BiCU failure (Damaged laser ASIC) • Disconnected LDB harness
• Remedy: • Cycle the power off/on. • Check for condensation on the LDB. • Check the harness between LDB (Synchronizing mechanism) and BiCU. • Replace the LD unit. • Replace the BiCU. • Replace the harness between LDB and BiCU.

• Code: 230-01
• Description: FGATE ON error: Bk. FGATE signal cannot be received even when the laser is ready to emit. This SC is detected when the machine is copying.
• Causes: • Connection error between BiCU and Controller • BiCU failure (Damaged laser ASIC)
• Remedy: • Cycle the power off/on. • Check the connection between BiCU and Controller. • Replace the BiCU.

• Code: 230-02
• Description: FGATE ON error: Cy. FGATE signal cannot be received even when the laser is ready to emit. This SC is detected when the machine is copying.
• Causes: • Connection error between BiCU and Controller • BiCU failure (Damaged laser ASIC)
• Remedy: • Cycle the power off/on. • Check the connection between BiCU and Controller. • Replace the BiCU.

• Code: 230-03
• Description: FGATE ON error: Ma. FGATE signal cannot be received even when the laser is ready to emit. This SC is detected when the machine is copying.
• Causes: • Connection error between BiCU and Controller • BiCU failure (Damaged laser ASIC)
• Remedy: • Cycle the power off/on. • Check the connection between BiCU and Controller. • Replace the BiCU.

• Code: 230-04
• Description: FGATE ON error: Ye. FGATE signal cannot be received even when the laser is ready to emit. This SC is detected when the machine is copying.
• Causes: • Connection error between BiCU and Controller • BiCU failure (Damaged laser ASIC)
• Remedy: • Cycle the power off/on. • Check the connection between BiCU and Controller. • Replace the BiCU.

• Code: 231-01
• Description: FGATE OFF error: Bk. FGATE signal is not OFF even when the laser is ready to end. This SC is detected when the machine is copying.
• Causes: • Connection error between BiCU and Controller • BiCU failure (Damaged laser ASIC)
• Remedy: 1. Cycle the power off/on. 2. Check the connection between IPU and Controller. 3. Replace the BiCU.

• Code: 231-02
• Description: FGATE OFF error: Cy. FGATE signal is not OFF even when the laser is ready to end. This SC is detected when the machine is copying.
• Causes: • Connection error between BiCU and Controller • BiCU failure (Damaged laser ASIC)
• Remedy: 1. Cycle the power off/on. 2. Check the connection between IPU and Controller. 3. Replace the BiCU.
