• Code: SC270-10
• Description: LD ASIC communication error: Others On startup: “Door open” status was cleared but did not change to “Door closed” status. Details: On startup: After clearing PATMOS “Door open” status, checks the status of the door after “Door open” determination period. Failure to detect “Door closed” status constitutes an SC.
• Causes: • PATMOS defective • HORUS defective • BCU defective • IPU defective • Harness defective • Interlock defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the IPU board. • Replace the BCU board. • Replace the LDB harness.

• Code: SC274-01
• Description: Image transfer error: Bk. • On detection of lane abnormality • On detection of elastic buffer overflow/underflow • On detection of STP error • On detection of END error Details: • When DES status is detected as abnormal.
• Causes: • IPU defective • Harness defective • LDB defective • GAVD defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the IPU board. • Replace the BCU board. • Replace the LDB harness.

• Code: SC274-03
• Description: Image transfer error: Ma. • On detection of lane abnormality • On detection of elastic buffer overflow/underflow • On detection of STP error • On detection of END error Details: • When DES status is detected as abnormal.
• Causes: • IPU defective • Harness defective • LDB defective • GAVD defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board. • Replace the IPU board. • Replace the BCU board. • Replace the LDB harness.

• Code: SC276-01
• Description: Microcomputer communication error: Bk. APC microcomputer does not respond. Details: • Detected an abnormality concerning GAVD interruption.
• Causes: • LDB defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board.

• Code: SC276-03
• Description: Microcomputer communication error: Ma. APC microcomputer does not respond. Details: • Detected an abnormality concerning GAVD interruption.
• Causes: • LDB defective
• Remedy: • Cycle the machine off/on. • Replace the LSU board.

• Code: SC285-00
• Description: MUSIC error. The results of MUSIC pattern reading failed 4 times while the machine is turned ON. Details: • When MUSIC fails 4 times while the machine is turned ON. (The count is cleared when the machine is turned OFF e.g. when entering sleep mode.) • TM sensor sampling error • Sensor LED adjustment error • Patch number error • Transfer belt flaw error • Main registration error • Sub registration error • Main scan magnification ratio error • Main scan magnification ratio deviation error
• Causes: • Belt flawed or smudged • Sensor smudged or defective • Pattern density defection
• Remedy: • Cycle the machine off/on. • Replace the TM sensor. • Replace the belt. • Process control • Cleaning

• Code: SC286-01
• Description: LD shutter open error. Detected an erratic movement during closing or opening.
• Causes: • Shutter motor movement error • Sensor defective • Links broken
• Remedy: • Cycle the machine off/on.(In case of a malfunction) • Replace the LSU. (In case of defective parts)

• Code: SC286-02
• Description: LD shutter close error Detected an erratic movement during opening.
• Causes: • Shutter motor movement error • Sensor defective • Links broken
• Remedy: • Cycle the machine off/on.(In case of a malfunction) • Replace the LSU. (In case of defective parts)
