• Code: SC202-00
• Description: Polygon Motor: ON Timeout Error After the polygon motor turned on, or within T1 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 or polygon motor • Replace the polygon harness • Replace the IPU board

• Code: SC203-00
