• Code: SC161-01
• Description: IPU Error (LSYNC abnormal) An error occurred during the self-diagnostic test performed every time the machine is turned on, or returns to full operation from energy save mode.
• Causes: • IPU (BiCU, iCTL) board defective (ASIC-LEO connection failure, LSYNC abnormal, etc.) • Cable between SBU and IPU (or BiCU) defective
• Remedy: • Replace the IPU (or BiCU) board. • Check the cable between SBU and IPU (or BiCU)

• Code: SC161-02
• Description: IPU error (Ri response abnormal) The machine detects an error during an access to the Ri.
• Causes: IPU (BiCU, iCTL) board defective (Ri response abnormal, etc.)
• Remedy: Replace the IPU (or BiCU) board.

• Code: SC165-00
• Description: Copy data security unit error • 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.
• Causes: • 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: SC185-00
• Description: CIS transmission error The data read from the ASIC register on the CIS were not as expected. Details: • Occurs when a serial communication error between the CIS board and the DF board is detected. Occurs also when an error is detected during initialization of the ASIC on the CIS. • This can happen during initialization and feeding. The first and second consecutive occurrences of each constitute jams. The third occurrence constitutes an SC.
• Causes: • Connector or harness between DF board and CIS board is disconnected or defective • ASIC on the CIS is defective • Boot failure of ASIC on the CIS
• Remedy: • Reconnect the power/signal harness. • Replace the CIS and CIPB. • Replace the ADF main control board. • Replace the power/signal harness.

• Code: SC186-00
• Description: CIS LED error. During initialization: • The ratio between the average values of leading-edge area and rear-edge area is out of specification. • Shading data peak value is below specification. During scanning: • Shading data peak value is below specification. Details: During initialization: • Occurs when one out of two CIS LEDs is malfunctioning, causing the difference between the average values of leading-edge area and rear-edge area to be large (CIS LED error detection). • Occurs when both of the CIS LEDs are malfunctioning (unlit), causing the shading data peak value to be extremely low (CIS white level adjustment). During scanning: • Occurs when both of the CIS LEDs are malfunctioning (unlit), causing the shading data peak value to be extremely low (CIS scan control, gray balance adjustment/confirmation). • The first and second consecutive occurrences of each constitute initial/feed jams. The third occurrence constitutes an SC.
• Causes: During initialization: • One or two out of two CIS LEDs are defective During scanning: • Both of the CIS LEDs are defective.
• Remedy: • Reconnect the power/signal harness. • Replace the CIS and CIPB. • Replace the CIS background white roller. • Replace the power/signal harness. • Replace the ADF main control board.

• Code: SC187-00
• Description: CIS black level error The black level scanned by CIS is abnormal. Details: • Occurs when abnormality is detected in the process of black level generation – detection. • The first and second consecutive occurrences constitute initial jams. The third occurrence constitutes an SC.
• Causes: CIS defective
• Remedy: Replace the CIS and CIPB.

• Code: SC188-00
• Description: CIS white level error • The shading data peak value read out from the CIS is abnormal. • The shading data peak value is not within the specified range from the target value. (The target value is set with SP4-784-001/ SP4-785-001/SP4-786-001.) Details: • Occurs when abnormality is detected in the process of CIS shading data peak detection. • The first and second consecutive occurrences constitute initial jams. The third occurrence constitutes an SC.
• Causes: CIS defective
• Remedy: • Reconnect the power/signal harness. • Replace the CIS and CIPB. • Replace the CIS background white roller. • Replace the power/signal harness.

• Code: SC189-00
• Description: CIS gray balance adjustment error The difference between gray balance adjustment target value and the value scanned from the GS20 chart was out of specification upon execution of gray balance adjustment confirmation (SP4-705-002). Details: • Occurs when gray balance adjustment fails. • The first occurrence constitutes an SC (not an initial jam).
• Causes: CIS defective
• Remedy: Replace the adjustment chart. (Degradation due to scratches and smudges)
