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 (or BCU) board defective (ASIC-BREIT connection failure, LSYNC abnormal, etc.) • Cable between SBU and IPU (or BCU) defective
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: 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 unit (CIS and CIPB). • Replace the ADF 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 unit (CIS and CIPB). • Replace the CIS background white roller. • Replace the power/signal harness. • Replace the ADF main control board.
