Description: Polygon motor error 3: XSCRDY signal error The SCRDY_N signal goes HIGH (inactive) while the laser diode is firing.
Causes: • Disconnected or defective harness to polygon motor driver board • Defective polygon motor • Defective polygon motor driver board
Remedy: 1. Check or replace the harness. 2. Replace the polygon motor. 3. Replace the IPU board. 4. Replace the BCU.
Code: 220
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 unit. 3. Replace the IPU board. 4. Replace the BCU.
Code: 222

Remedy: 1. Check the connectors. 2. Replace the laser unit. 3. Replace the IPU board. 4. Replace the BCU.
Code: 226
Description: Laser synchronizing detection error: start position [C] 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 unit. 3. Replace the IPU board. 4. Replace the BCU.
Code: 230
Description: FGATE ON error: K 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 BCU. 2. Replace the BCU. 3. Replace the controller board.
