Description: Laser synchronizing detection error: start position [M]: 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 EGB
Remedy: 1. Check the connectors. 2. Replace the laser-synchronizing detector. 3. Replace the LDB. 4. Replace the EGB.
Code: 225

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 EGB. • Defective EGB
Remedy: 1. Check the connection between the controller board and the EGB. 2. Replace the EGB. 3. Replace the controller board.
Code: 231
Description: FGATE OFF error: Bk • 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.
Causes: • Defective ASIC (Lupus) • Poor connection between controller and EGB. • Defective EGB
Remedy: 1. Check the connection between the controller board and the EGB. 2. Replace the EGB. 3. Replace the controller board.
