Description: SBU Communication Error • Connection to SBU cannot be confirmed. (Connection detection error) • Cannot communicate with the SBU, or the communication result is abnormal.
Causes: • SBU defective • The other side of the communication (BCU, IPU etc.) defective • Power/signal harness defective
Remedy: 1. Turn the power off/on. 2. Reconnect the power/signal harness. 3. Replace the following parts: • Replace the SBU board. • Replace the IPU board. • Replace the BCU board. • Replace the power/signal harness.
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.
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. (An initialization jam/transport jam occurs on 2 continuous occasions during either initialization or transport, and on the 3rd continuous occasion, an SC is generated)
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: 1. Reconnect the power/signal harness. 2. Replace the following parts: • 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. (An initialization jam/transport jam occurs on 2 continuous occasions during either initialization or transport, and on the 3rd continuous occasion, an SC is generated)
Causes: During initialization: • One or two out of two CIS LEDs are defective During scanning: • Both of the CIS LEDs are defective.
Remedy: 1. Reconnect the power/signal harness. 2. Replace the following parts: • Replace the CIS and CIPB. • Replace the CIS background white roller. • Replace the power/signal harness. • Replace the ADF main control board.
