Description: Polygon Motor: ON Timeout Error After the polygon motor turned on, or within 10 sec. after the rpm’s changed, the motor did not enter READY status.
Causes: • The interface harness to the polygon motor driver damaged or not connected correctly. • Polygon motor or polygon motor driver defective • Polygon motor drive pulse cannot be output correctly. (Polygon controller) • XSCRDY signal observation failing (Polygon controller)
Remedy: • Turn the power off/on. • Replace the laser unit. • Replace the harness. • Replace the IPU board.
Code: SC203-00
Description: Polygon Motor: OFF Timeout Error The XSCRDY signal (polygon ready) never becomes inactive (H) within 3 sec. after the polygon motor went OFF.
Causes: • The interface harness to the polygon motor driver damaged or not connected correctly. • Polygon motor or polygon motor driver defective • Polygon motor drive pulse cannot be output correctly. (Polygon controller) • XSCRDY signal observation failing (Polygon controller)
Remedy: • Turn the power off/on. • Replace the laser unit. • Replace the harness. • Replace the IPU board.
Code: SC204-00
Description: Polygon Motor: XSCRDY Signal Error During polygon motor rotation, the XSCRDY signal was inactive (H) for longer than one rotation of the polygon.
Causes: • The interface harness to the polygon motor driver damaged or not connected correctly. • Polygon motor or polygon motor driver defective
Remedy: • Turn the power off/on. • Replace the laser unit. • Replace the harness. • Replace the IPU board.
Code: SC220-00
Description: Laser Synchronization Detection Error: Leading Edge The laser synchronizing detection signal for the start position of the LD was not output for 200msec. after LDB unit turned on with the polygon motor rotating normally.
Causes: • The interface harness to the synchronization detection unit damaged or not connected correctly. • Synchronization detection board defective • Beam does not enter photo detector. • Abnormality around GAVD • IDB (LED driver) defective • LDB defective • IPU defective
Remedy: • Turn the power off/on. • Replace the laser unit. • Replace the harness. • Replace the IPU board.
Code: SC230-00
Description: FGATE ON Error The FGATE signal did not turn ON within the given time period after the writing process started.
Causes: • GAVD defective • Image processing ASIC defective • BCU, controller board not connected correctly or defective • Harness between BCU and LDB defective
Remedy: • Turn the power off/on. • Replace the harness between IPU and laser unit. • Replace the IPU board. • Replace the controller board.
Code: SC231-00
Description: FGATE OFF Error The FGATE signal did not turn OFF within the given time period after the writing process ended.
Causes: • GAVD defective • Image processing ASIC defective • IPU, controller board not connected correctly or defective • Harness between IPU and LDB defective
Remedy: • Turn the power off/on. • Replace the harness between IPU and laser unit. • Replace the IPU board. • Replace the controller board.
