• Code: 226
• Description: Laser synchronizing detection error: start position [C]: LD0
  The laser synchronizing detection signal for the start position of the LDB [K], [Y], [M], [C] 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 LDB • Defective IPU
• Remedy: 1. Check the connectors. 2. Replace the laser-synchronizing detector. 3. Replace the LDB. 4. Replace the IPU.

• Code: 227
• Description: Laser synchronizing detection error: start position [C]: LD1
  The laser synchronizing detection signal for the start position of the LDB [K], [Y], [M], [C] 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 LDB • Defective IPU
• Remedy: 1. Check the connectors. 2. Replace the laser-synchronizing detector. 3. Replace the LDB. 4. Replace the IPU.

• Code: 230
• Description: FGATE ON error: Bk
  The PFGATE ON signal does not assert within 5 seconds after processing the image in normal job or MUSIC for start position [K].
• Causes: • Defective ASIC (Lupus) • Poor connection between controller and IPU. • Defective IPU
• Remedy: 1. Check the connection between the controller board and the IPU. 2. Replace the IPU. 3. Replace the controller board.

• Code: 231
• Description: FGATE OFF error: Bk
• Causes: • The PFGATE ON signal still asserts within 5 seconds after processing the image in normal job or MUSIC for end position [K]. • The PFGATE ON signal still asserts when the next job starts.
• Remedy: 1. Check the connection between the controller board and the IPU. 2. Replace the IPU. 3. Replace the controller board.

• Code: 232
• Description: FGATE ON error: Y
  The PFGATE ON signal does not assert within 5 seconds after processing the image in normal job or MUSIC for start position [Y].
• Causes: • Defective ASIC (Lupus) • Poor connection between controller and IPU. • Defective IPU
• Remedy: 1. Check the connection between the controller board and the IPU. 2. Replace the IPU. 3. Replace the controller board.

• Code: 233
• Description: FGATE OFF error: Y
  • The PFGATE ON signal still asserts within 5 seconds after processing the image in normal job or MUSIC for end position [Y]. • The PFGATE ON signal still asserts when the next job starts.
• Causes: • Defective ASIC (Lupus) • Poor connection between controller and IPU. • Defective IPU
• Remedy: 1. Check the connection between the controller board and the IPU. 2. Replace the IPU. 3. Replace the controller board.

• Code: 234
• Description: FGATE ON error: M
  The PFGATE ON signal does not assert within 5 seconds after processing the image in normal job or MUSIC for start position [M].
• Causes: • Defective ASIC (Lupus) • Poor connection between controller and IPU. • Defective IPU
• Remedy: 1. Check the connection between the controller board and the IPU. 2. Replace the IPU. 3. Replace the controller board.

• Code: 235
• Description: FGATE OFF error: M
  • The PFGATE ON signal still asserts within 5 seconds after processing the image in normal job or MUSIC for end position [M]. • The PFGATE ON signal still asserts when the next job starts.
• Causes: • Defective ASIC (Lupus) • Poor connection between controller and IPU. • Defective IPU
• Remedy: 1. Check the connection between the controller board and the IPU. 2. Replace the IPU. 3. Replace the controller board.
