• Remedy: • Replace the IPU (or BCU) board. • Check the cable between SBU and IPU (or BCU)

• Code: SC165
• Description: Copy data security unit error
• Causes: • The copy data security option is enabled in the User Tools but the option board is detected as missing or defective. • The copy data security option was detected as defective when the machine was turned on or returned from energy save mode. • Copy data security unit board not installed correctly • Copy data security unit board defective
• Remedy: • Reinstall the copy data security unit board. • Replace the copy data security unit board.

• Code: SC195

• Code: SC202
• 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
• 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 or polygon motor • Replace the polygon harness • Replace the IPU board

• Code: SC204
• 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 or polygon motor • Replace the polygon harness • Replace the IPU board

• Code: SC220
• Description: Laser synchronization detection error: LD0 The laser synchronizing detection signal for the start position of the LD was not output for 500 msec. 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 or polygon motor • Replace the polygon harness • Replace the IPU board
