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.
Code: 210-01
Description: Laser synchronizing detection error: end position [K] The laser synchronizing detection signal for the end position of LDB [K], [C], [M], [Y] 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 IPU
Remedy: 1. Check the connectors. 2. Replace the harness of the LD board. 3. Replace the laser optics housing unit. 4. Replace the IPU.
Code: 210-02
Description: Laser synchronizing detection error: end position [C] The laser synchronizing detection signal for the end position of LDB [K], [C], [M], [Y] 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 IPU
Remedy: 1. Check the connectors. 2. Replace the harness of the LD board. 3. Replace the laser optics housing unit. 4. Replace the IPU.
Code: 210-03
Description: Laser synchronizing detection error: end position [M] The laser synchronizing detection signal for the end position of LDB [K], [C], [M], [Y] 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 IPU
Remedy: 1. Check the connectors. 2. Replace the harness of the LD board. 3. Replace the laser optics housing unit. 4. Replace the IPU.
Code: 210-04
Description: Laser synchronizing detection error: end position [Y] The laser synchronizing detection signal for the end position of LDB [K], [C], [M], [Y] 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 IPU
Remedy: 1. Check the connectors. 2. Replace the harness of the LD board. 3. Replace the laser optics housing unit. 4. Replace the IPU.
Code: 220-01
Description: Laser synchronizing detection error: start position [K]: LD1 The laser synchronizing detection signal for the start position of the LDB [K], [C], [M], [Y] 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.
