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: Polygon motor error 1: On timeout
The XSCRDY signal did not go LOW (Active) within 10 sec. after the polygon motor was turned on.
Causes: • Polygon motor drive board I/F harness loose, disconnected, or damaged • Polygon motor drive board defective • Polygon motor defective
Code: 336
Description: Polygon motor error 2: Off timeout
The XSCRDY signal did not go HIGH (Inactive) within 3 sec. after the polygon motor was turned off.
Causes: • Polygon motor drive board I/F harness loose, disconnected, or damaged • Polygon motor drive board defective • Polygon motor defective
Code: 337
Description: Polygon motor error 3: XSCRDY signal error
The XSCRDY signal did not go HIGH (Inactive) after the polygon motor had been rotating normally for 200 ms.
Causes: • Polygon motor drive board I/F harness loose, disconnected, or damaged • Polygon motor drive board defective • Polygon motor defective
Code: 338
Description: Polygonal Mirror Motor Error 4: Unstable Timeout
The XSCRDY signal is detected LOW) (Active) after the polygonal mirror motor switches on, but the signal is not detected LOW after 1 s has elapsed, and not detected after another 500 ms has elapsed.
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.
