Description: Polygon motor error 4: XSCRDY signal unstable
When the polygon motor switches on, or after the speed of the motor changes, the SCRDY_N signal goes HIGH (inactive).
Causes: • Harness to polygon motor driver board disconnected, defective • Polygon motor defective • Polygon motor driver board defective
Code: SC210
Description: Laser beam detection error 1: K (Black)
The laser synchronization sensor failed to detect the beginning and end of the laser beam flash for the designated color onto the polygon mirror while the mirror is rotating at the prescribed number of revolutions.
Description: Laser beam detection error 1: Y (Yellow)
The laser synchronization sensor failed to detect the beginning and end of the laser beam flash for the designated color onto the polygon mirror while the mirror is rotating at the prescribed number of revolutions.
Description: Laser beam detection error 1: M (Magenta)
The laser synchronization sensor failed to detect the beginning and end of the laser beam flash for the designated color onto the polygon mirror while the mirror is rotating at the prescribed number of revolutions.
Description: Laser beam detection error 1: C (Cyan)
The laser synchronization sensor failed to detect the beginning and end of the laser beam flash for the designated color onto the polygon mirror while the mirror is rotating at the prescribed number of revolutions.
Description: Laser Synchronization Detector Error 1: K Leading Edge: LD0
While the polygon motor is rotating normally, no synchronizing detection signal is output for LD0 black, or 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 • Beam not reflected in photo detection • GAVD on the BICU is defective • LD driver board defective • LDB defective • BCU defective • Check board connections, replace
