Description: LD unit home position error 2
The LD unit home position sensor did not detect the OFF condition when the LD unit moved from its home position.
Causes: • LD unit HP sensor/harness defective • LD unit home position sensor defective • LD positioning motor connector or harness loose, broken, defective • LD unit or LD unit motor blocked • LD unit motor defective
Code: 329
Description: LD unit beam pitch adjusted incorrectly
The LD unit HP sensor did not detect the ON condition while changing the LD unit position to correct the LD position or change the resolution (dpi).
Causes: • After initialization of the SP modes, SP2-109-3 or SP2-109-4 did not execute. • If this SC code appears at power on or during a print job, do these two SP codes then turn the main power off/on. • If executing these two SP codes does not solve the problem, check the LD unit drive mechanism (the harness of the LD board or other object could be blocking the LD drive mechanism, preventing adjustment of the pitch). • Do SP 5801, then do SP2109 3 and SP2109 4 again.
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 was detected LOW) (Active) after the polygonal mirror motor switched on, but the signal was not detected LOW after 1 sec., and was not detected after another 500 ms.
Causes: • I/F harness of the polygonal mirror motor disconnected or defective. • Polygonal mirror motor or polygonal mirror motor drive board defective.
