• Code: SC240-03
• Description: LD error: Ma. When two errors were detected consecutively while monitoring the VTEC for LD error registers in 350msec intervals after LD initialization. Details: The VTEC LD error flag was detected twice consecutively when the LD turned on after initialization.
• Causes: • LD degradation (LD broken, shift of output characteristics etc.) • LD driver defective • VTEC defective • The interface harness damaged or not connected correctly. • Large main scan magnification rate
• Remedy: • Cycle the main power off/on. • Replace the IPU board. • Replace the LSU board. • Replace the LD unit. • Replace the harness. • Correct the main scan magnification SP* * SP2-184-006 through 009 = 269600 SP2-102-001,007 = 123 SP2-102-016 through 025 = 0 Adjust SP2-184-006 through 009 while checking the images until the values of SP2-102-001,007 become 123 ± 30.

• Code: SC260-01
• Description: Laser Thermistor Error: Bk. • The reading of the thermistor in the laser unit was less than 10 °C (50 °F), indicating that the thermistor has disconnected. • The reading of the thermistor in the CK or YM laser unit was more than 80 °C (176 °F), indicating that the thermistor has shorted out. Details: When the thermistor voltage is out of range (-10 to 80 °C) after the machine was turned on.
• Causes: • Thermistor defective • Harness defective • BCU defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the LSU harness.

Details: When the thermistor voltage is out of range (-10 to 80 °C) after the machine was turned on.
• Causes: • Thermistor defective • Harness defective • BCU defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the LSU harness.

• Code: SC265-02
• Description: Skew correction error: Cy. The skew control pulse total is not within range.
• Causes: • Skew motor defective • Harness defective • Optical system defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the LSU harness.

• Code: SC265-03
• Description: Skew correction error: Ma. The skew control pulse total is not within range.
• Causes: • Skew motor defective • Harness defective • Optical system defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the LSU harness.

• Code: SC265-04
• Description: Skew correction error: Ye. The skew control pulse total is not within range.
• Causes: • Skew motor defective • Harness defective • Optical system defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the LSU harness.

• Code: SC270-01
• Description: LD ASIC communication error: Bk. On startup: Written to and read the same register but the values were different. VTEC: Monitored the parity and retried three times. Details: • On startup: Data 0x5A5A and 0xA5A5 are written to a predetermined register. Then the register is read and the read data is compared to the are compared • VTEC: Monitors parity during communication. If it does not match, retries up to three times. The second retry constitutes an SC.
• Causes: • VTEC defective • HORUS defective • BCU defective • IPU defective • Harness defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the IPU board. • Replace the BCU board. • Replace the LDB harness.
