Description: Laser synchronizing detection error: end position [M] The laser synchronizing detection signal for the end position of LDB [K], [Y], [M], [C] is not detected for one second after the LDB unit turned on when detecting the main scan magnification.
Causes: • Disconnected or defective harness to synchronizing detector for end position • Defective synchronizing detector board • Defective LD board or driver • Defective EGB
Remedy: 1. Replace the harness of the LD board. 2. Replace the laser optics housing unit. 3. Replace the EGB.
Code: 213

Causes: • Disconnected or defective harness to synchronizing detector for end position • Defective synchronizing detector board • Defective LD board or driver • Defective EGB
Remedy: 1. Replace the harness of the LD board. 2. Replace the laser optics housing unit. 3. Replace the EGB.
Code: 220
Description: Laser synchronizing detection error: start position [K]: 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: 221
