• Code: 230
• Description: FGATE error
  The PFGATE ON signal does not assert within 1 second. The PFGATE ON signal still assert within 7 seconds, after processing the image in a normal job
• Causes: • Defective engine board • Defective controller board • Disconnect harness

• Code: 302
• Description: Charge roller current leak
  The PWM duty output exceeded 60% for longer than 200 ms, indicating a leak in the charge roller current.
• Causes: • Cartridge (charge roller) defective • High voltage supply board defective • Defective cartridge connection

• Code: 320
• Description: Polygon motor error
  The polygon motor did not enter the lock state within 10 sec. after it switched on. -or- Once the polygon motor was detected in the lock state after started to rotate, within 0.2 sec. it entered the unlock state. -or- After the polygon motor switched off, it did not enter unlock state within 3 sec.
• Causes: • Polygon motor • Polygon motor cable

• Code: 322
• Description: 1st beam laser synchronization error
  With all doors closed the polygon motor is locked and not rotating, or the laser synchronization detector could not detect 1st beam laser detection signal within 500 ms.
• Causes: • Laser synchronization detector board out of position • Laser synchronization detector board or cable defective • Laser synchronization mirror out of position • LD unit defective • Engine board defective

• Code: 323
• Description: LD drive current exceeded
  The LD driver detected an error for 50 ms.
• Causes: • LD unit defective

• Code: 326
• Description: 2nd beam laser synchronization error
  With all doors closed the polygon motor is locked and not rotating, or the laser synchronization detector could not detect 2nd beam laser detection signal within 500 ms.
• Causes: • Laser synchronization detector board out of position • LD unit defective • Engine board defective

• Code: 391
• Description: Development bias leak
  A development bias leak signal was detected for 200 ms.
• Causes: • High voltage supply board defective • Defective cartridge connection

• Code: 500
• Description: Main motor error
  The machine does not detect a main motor lock signal within 700 ms after the main motor started to rotate. -or- The machine detects a main motor lock signal within 500 ms after the main motor started to rotate, after that, the main motor lock signal does not detect within 200ms. -or- The machine does not detect a main motor lock signal within 200 ms after the main motor switched off.
• Causes: • Main motor defective • Mechanical overload on the drive mechanism
