Description: Laser synchronizing detection error: start position [K] 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 BICU.
Remedy: 1. Check the connectors. 2. Replace the laser-synchronizing detector. 3. Replace the LDB. 4. Replace the BICU.
Code: 222

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 BICU. Defective BICU.
Remedy: 1. Check the connection between the controller board and the BICU. 2. Replace the BICU. 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 BICU. Defective BICU.
Remedy: 1. Check the connection between the controller board and the BICU. 2. Replace the BICU. 3. Replace the controller board.
