Description: LD unit home position error 1
The LD unit home position sensor does not detect an on condition when the LD unit moves to its home position.
Causes: • HP sensor/harness defective • LD unit home position sensor defective • LD positioning motor harness defective • LD unit movement blocked because of incorrect connector routing
Code: 328
Description: LD unit home position error 2
The LD unit home position sensor does not detect an off condition when the LD unit moves from its home position.
Causes: • HP sensor/harness defective • LD positioning/harness motor defective • LD unit movement blocked because of incorrect connector routing
Code: 329
Description: LD unit beam pitch adjusted incorrectly
The LD unit HP sensor does not detect the ON condition while changing the LD unit position for correcting the LD position or changing the dpi.
Causes: • After initialization of the SP modes, SP2-109-3 or SP2-109-4 was not executed. • The harness is blocking the LD drive (PCB), preventing adjustment of the pitch.
Code: 335
Description: Polygonal Mirror Motor Error 1: ON Timeout
The XSCRDY signal is not issued (LOW: Active) within 25 s after the polygonal mirror motor switches on.
Causes: • I/F harness of the polygonal mirror motor disconnected or defective. • Polygonal mirror motor or polygonal mirror motor driver defective. • Polygonal mirror motor drive pulse is not output incorrectly. • GABIC cannot monitor XSCRDY signal.
Code: 336
Description: Polygonal Mirror Motor Error 2: OFF Timeout
The XSCRDY signal is not issued (HIGH: Inactive) within 2 s after the polygonal mirror motor switches off.
Causes: • I/F harness of the polygonal mirror motor disconnected or defective. • Polygonal mirror motor or polygonal mirror motor driver defective. • Polygonal mirror motor drive pulse is not output incorrectly. • GABIC cannot monitor XSCRDY signal.
Code: 337
Description: Polygonal Mirror Motor Error 3: XSCRDY Signal Error
The XSCRDY is not issued (HIGH: Inactive) after the polygonal mirror motor has been rotating normally for 600 ms.
Causes: • I/F harness of the polygonal mirror motor disconnected or defective. • Polygonal mirror motor or polygonal mirror motor driver defective. • Polygonal mirror motor drive pulse is not output incorrectly. • GABIC cannot monitor XSCRDY signal.
