Description: Black level detection error The black level cannot be adjusted to the target level at the time of turning on the scanner (when the main power is turned ON).
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1. Reconnect the following connectors. • Scanner Carriage – BiCU (PCB16) connector • BiCU (PCB16) – IOB (PCB17) connector 2. Scanner carriage defective Replace the scanner carriage. 3. BiCU (PCB16) defective Replace the BiCU (PCB16). 4. Harness defective Replace the following harnesses. • Scanner Carriage – BiCU (PCB16) harness • BiCU (PCB16) – IOB (PCB17) harness 5. IOB (PCB17) defective Replace the IOB (PCB17).
Code: SC142-00
Description: White level detection error The white level cannot be adjusted to the target level during auto gain control.
Causes: • Condensation in the scanner unit • Scanner Carriage defective • BiCU (PCB16) defective • Harness defective • Connector disconnected • White Guide Plate dirty or attachment fault
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1.

Error detection timing: At the time of turning on the scanner (when the main power is turned ON or when the machine returns from energy saving mode)
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1. Reconnect the following connectors. • Scanner Carriage – BiCU (PCB16) connector • BiCU (PCB16) – IOB (PCB17) connector 2. Scanner carriage defective Replace the scanner carriage. 3. BiCU (PCB16) defective Replace the BiCU (PCB16). 4. IOB (PCB17) defective Replace the IOB (PCB17). 5. Harness defective Replace the following harnesses. • Scanner Carriage – BiCU (PCB16) harness • BiCU (PCB16) – IOB (PCB17) harness
Code: SC151-00
Description: Black level detection error (back side) The black level cannot be adjusted to the target level. Error detection timing; • During a scan from DF • When confirming the lowest black level
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1. Reconnect the connector. Reconnect the following connectors; • Scanner Carriage – BiCU (PCB16) connector • BiCU (PCB16) – IOB (PCB17) connector 2. BiCU (PCB16) defective Replace the BiCU (PCB16). 3. CIS defective Replace the CIS. 4. Harness defective Replace the following harnesses. • CIS CONNECT PCB (PCB28)– BiCU (PCB16) harness • CIS – CIS CONNECT PCB (PCB28) harness 5. CIS CONNECT PCB (PCB28) defective Replace the CIS CONNECT PCB (PCB28).
Code: SC152-00
Description: White level adjustment error (back side) The white level cannot be adjusted to the target level during auto gain control.
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1. Check the white guide plate (DF). Check the DF white guide plate. If the white guide plate is in an unusual state, replace the white guide plate. 2. Reconnect the following connectors. • Scanner Carriage – BiCU (PCB16) connector • SBU (PCB3) – LEDB connector (SBU (PCB3) side connector which is on the scanner carriage) • BiCU (PCB16) – IOB (PCB17) connector 3. CIS defective Replace the CIS. 4. Harness defective Replace the following harnesses. • CIS CONNECT PCB (PCB28)– BiCU (PCB16) harness • CIS – CIS CONNECT PCB (PCB28) harness 5. BiCU (PCB16) defective Replace the BiCU (PCB16). 6. CIS CONNECT PCB (PCB28) defective Replace theCIS CONNECT PCB (PCB28).
Code: SC154-01
Description: Scanner communication error (back side) • CIS connection cannot be confirmed • Cannot communicate with CIS or other scanning device, or communication is abnormal Error detection timing; • During scanner startup (main power was turned on or the machine returned from energy saving mode) • During a scan
