Description: Laser Synchronization Detector Error 2: K Leading Edge (Other than LD0)
While the polygon motor is rotating normally, no synchronizing detection signal is output for black, leading edge for any LD other than LD0, even after the laser diode has been firing for 2 sec.
Causes: • Beam not reflected in photo detection • GAVD on the BICU defective • LD driver defective • LDB defective • BCU defective • Check board connections, replace
Code: SC222
Description: Laser Synchronization Detector Error 1: Y Leading Edge: LD0
While the polygon motor is rotating normally, no synchronizing detection signal is output for LD0 yellow, leading edge, even after the laser diode has been firing for 2 sec.
Causes: • Harness between the laser synchronizing detector and I/F unit is disconnected, defective • Laser synchronizing detector defective • GAVD on the BICU defective • LD driver board defective • LDB defective • BCU defective • Check board connections, replace
Code: SC223
Description: Laser Synchronization Detector Error 2: Y Leading Edge (Other than LD0)
While the polygon motor is rotating normally, no synchronizing detection signal is output for yellow, leading edgefor any LD other than LD0, even after the laser diode has been firing for 2 sec.
Causes: • Beam not reflected in photo detection • GAVD on the BICU defective • LD driver defective • LDB defective • BCU defective • Check board connections, replace
Code: SC224
Description: Laser Synchronization Detector Error 1: M Leading Edge: LD0
While the polygon motor is rotating normally, no synchronizing detection signal is output for LD0 magenta, leading edge, even after the laser diode has been firing for 2 sec.
Causes: • Harness between the laser synchronizing detector and I/F unit is disconnected, defective • Laser synchronizing detector defective • GAVD on the BICU defective • LD driver board defective • LDB defective • BCU defective • Check board connections, replace
Code: SC225
Description: Laser Synchronization Detector Error 2: M Leading Edge (Other than LD0)
While the polygon motor is rotating normally, no synchronizing detection signal is output for magenta, leading edge for any LD other than LD0, even after the laser diode has been firing for 2 sec.
Description: Laser Synchronization Detector Error 1: C Leading Edge: LD0
While the polygon motor is rotating normally, no synchronizing detection signal is output for LD0 cyan, leading edge, even after the laser diode has been firing for 2 sec.
Causes: • Harness between the laser synchronizing detector and I/F unit is disconnected, defective • Laser synchronizing detector defective • GAVD on the BICU defective • LD driver board defective • LDB defective • BCU defective • Check board connections, replace
