• Code: 195
• Description: Serial Number Mismatch Serial number stored in the memory does not have the correct code.
• Causes: EEPROM defective • BCU replaced without original EEPROM
• Remedy:

• Code: 202
• Description: Polygon motor error 1: ON timeout. The polygon mirror motor does not reach the targeted operating speed within 10 sec. after turning on or changing speed
• Causes: • Polygon motor/driver board harness loose or broken • Polygon motor/driver board defective • Laser optics unit defective • Bridge board defective
• Remedy:

• Code: 203
• Description: Polygon motor error 2: OFF timeout The polygon mirror motor does not leave the READY status within 3 sec. after the polygon motor switched off.
• Causes: • Polygon motor/driver board harness loose or broken • Polygon motor/driver board defective • Laser optics unit defective • Bridge board defective
• Remedy:

• Code: 204
• Description: Polygon motor error 3: XSCRDY signal error The SCRDY_N signal remains HIGH for 200 ms while the LD unit is firing.
• Causes: • Polygon motor/driver board harness loose or broken • Polygon motor/driver board defective • Laser optics unit defective • Bridge board defective
• Remedy:

• Code: 220
• Description: Laser synchronizing detection error: start position LD0 The laser synchronizing detection signal for the start position of the LDB is not output for two seconds after LDB unit turns on while the polygon motor is rotating normally
• Causes: • Disconnected cable from the laser synchronizing detection unit or defective connection • Defective laser synchronizing detector • Defective LD board • Defective BCU
• Remedy:

• Code: 221
• Description: Laser synchronizing detection error: start position LD1 The laser synchronizing detection signal for the start position of the LDB is not output for two seconds after LDB unit turns on while the polygon motor is rotating normally.
• Causes: • Disconnected cable from the laser synchronizing detection unit or defective connection • Defective laser synchronizing detector • Defective LD board • Defective BCU
• Remedy:

• Code: 230
• Description: FGATE ON error The FGATE signal does not assert within the prescribed time. (The bridge board generates the FGATE signal and sends it to the LD unit when the registration sensor switches on.)
• Causes: • BCU, Controller board harness loose or broken • Controller board defective • BCU defective
• Remedy:

• Code: 231
• Description: FGATE OFF error The FGATE signal does not assert within the prescribed time. (The bridge board generates the FGATE signal and sends it to the LD unit when the registration sensor switches on.)
• Causes: • BCU, Controller board harness loose or broken • Controller board defective • BCU defective
