• Code: SC195-00
• Description: Machine serial number error Comparison of the product identification code in the machine serial number (11 digits).
• Causes: The product identification code in the machine serial number (11 digits) does not match.
• Remedy: Re-enter the machine serial number.

• Code: SC202-01
• Description: Polygon Motor: ON Timeout Error: Bk. 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: • Cycle the machine off/on. • Replace the LSU. • Replace the polygon harness. • Replace the IPU board.

• Code: SC202-03
• Description: Polygon Motor: ON Timeout Error: Ma. 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: • Cycle the machine off/on. • Replace the LSU. • Replace the polygon harness. • Replace the IPU board.

• Code: SC203-01
• Description: Polygon Motor: OFF Timeout Error: Bk. The XSCRDY signal (polygon ready) never becomes inactive (H) 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: • Cycle the machine off/on. • Replace the LSU. • Replace the polygon harness. • Replace the IPU board.

• Code: SC203-03
• Description: Polygon Motor: OFF Timeout Error: Ma. The XSCRDY signal (polygon ready) never becomes inactive (H) 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: • Cycle the machine off/on. • Replace the LSU. • Replace the polygon harness. • Replace the IPU board.

• Code: SC204-01
• Description: Polygon Motor: XSCRDY Signal Error: Bk. During polygon motor rotation, the XSCRDY signal was inactive (H) for longer than one rotation of the polygon. Details: • Occurs when the PATMOS polygon error determination register detects that the XSCRDY signal was inactive (H) for longer than one rotation of the polygon (7 cycles of PMCLK). • The PATMOS polygon error determination register detects that the XSCRDY signal was inactive (H) for longer than one rotation of the polygon, and then refers to SCERR2.
• Causes: • Polygon motor or polygon motor driver defective • The interface harness to the polygon motor driver damaged or not connected correctly.
• Remedy: • Cycle the machine off/on. • Replace the LSU. • Replace the polygon harness.

• Code: SC204-03

• Causes: • Polygon motor or polygon motor driver defective • The interface harness to the polygon motor driver damaged or not connected correctly.
• Remedy: • Cycle the machine off/on. • Replace the LSU. • Replace the polygon harness.

• Code: SC210-01
• Description: Trailing Edge Beam Error: Bk. When the main scan magnification rate was measured, the value measured between 2 points was out of specification. Details: • When a trailing edge beam detection error flag is asserted to VTEC status register. • The CPU detected an error flag when measuring the main scan magnification rate.
• Causes: • The interface harness to the beam detection unit damaged or not connected correctly. • Beam detection board defective • Beam does not enter photodetector. • Abnormality around VTEC • LDB defective • BCU defective • Large main scan magnification rate
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the IPU board. • Replace the BCU board. • 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.
