Description: Polygon motor error 3: XSCRDY signal error
Causes: The SCRDY_N signal remains HIGH for 200 ms while the LD unit is firing.
Remedy: • Polygon motor/driver board harness loose or disconnected • Polygon motor/driver board defective • Laser optics unit defective • IPU (EGB) defective 1. Replace the interface harness of the laser optics unit. 2. Replace the laser optics unit. 3. Replace the EGB (Engine Board).
Causes: The laser synchronizing detection signal for LDB [K]/[Y] is not output after the LDB unit has turned on while the polygon motor is rotating normally.
Causes: The laser synchronizing detection signal for LDB [M]/[C] is not output after the LDB unit has turned on while the polygon motor is rotating normally.
Remedy: • Disconnected cable from the laser synchronizing detection unit or defective connection • Defective laser synchronizing detector • Defective LDB • Defective EGB 1. Check the connectors. 2. Replace the laser optics unit. 3. Replace the EGB.·
