Description: LED Error The peak white level is less than the prescribed value. This SC is detected when the machine adjusts the LED’s light intensity or before just scanning.
Causes: • Loose connector • Defective scanner carriage • Defective BiCU (PCB1) • Damaged harness (FFC) • White plate for shading adjustment is dirty or incorrect. • Scanning guide plate is dirty or incorrect.
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 scanning guide plate. If the scanning guide plate is dirty, clean it. 2. Reconnect the following connectors: • Scanner Carriage - BiCU harness (FFC) • SBU (PCB11) - LEDB (scanner lamp board) harness (FFC) connector 3. Check the whit plate that is used for shading adjustment. This plate is attached to the back side of the sheet-through or platen exposure glass. If the white plate is dirty, clean it or replace the sheet-through exposure glass. 4. Replace the scanning guide plate. 5. Replace the scanner carriage. 6. Replace the BiCU (PCB1). 7. Replace the following harnesses: • Scanner Carriage - BiCU (PCB1) (FFC)
Code: SC101-02
Description: LED Error (LED illumination adjustment) The peak white level is less than the prescribed value. This SC is detected when the machine adjusts the LED’s light intensity.
Causes: • Condensation in scanner unit • Connector defective (disconnected, loose) • BiCU defective • Scanner carriage defective • Harness defective • White plate for shading adjustment is dirty or installed incorrectly.
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 harness (FFC) • SBU (PCB11) - LEDB (scanner lamp board) harness (FFC) connector 2. Check the whit plate that is used for shading adjustment. This plate is attached to the back side of the sheet-through or platen exposure glass. If the white plate is dirty, clean it or replace the sheet-through exposure glass. 3. Replace the scanner carriage 4. Replace the BiCU (PCB1). 5. Replace the following harnesses: • Scanner Carriage - BiCU (PCB1) (FFC)
Code: SC102-00
Description: LED Intensity Adjustment Error The peak white level cannot be in the prescribed value even though adjusting several times. This SC is detected when the machine adjusts the LED’s light intensity.
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 harness (FFC) • SBU (PCB11) - LEDB (scanner lamp board) harness (FFC) connector 2. Check the whit plate that is used for shading adjustment. This plate is attached to the back side of the sheet-through or platen exposure glass. If the white plate is dirty, clean it or replace the sheet-through exposure glass. 3. Replace the scanner carriage. 4. Replace the BiCU (PCB1). 5. Replace the following harnesses: • Scanner Carriage - BiCU (PCB1) (FFC)
Code: SC111-01
Description: LED Error (Scanning): Rear Side The peak white level is less than the prescribed value.
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 scanning guide plate (rear side). If the scanning guide plate is dirty or damaged, clean or replace it. 2. Replace the following harnesses: • CIS (S21) - BiCU (PCB1) (FFC) 3. Replace the CIS (S21). 4. Replace the harness (FFC). 5. Replace the BiCU (PCB1).
Code: SC112-00
Description: LED Illumination Adjustment Error: Rear Side The white level peak reached the prescribed threshold when the white plate was scanned after a specified number of adjustments.
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 scanning guide plate (rear side). If the scanning guide plate is dirty or damaged, clean or replace it. 2. Replace the following harnesses: • CIS (S21) - BiCU (PCB1) (FFC) 3. Replace the CIS (S21). 4. Replace the harness (FFC). 5. Replace the BiCU (PCB1).
Code: SC120-00
Description: Scanner Home Position Error 1 The Scanner HP Sensor (S20) did not go OFF : • During homing operation (power ON, leaving low power mode) • During auto adjustment (power ON, leaving low power mode) • During document, book scanning
Causes: • Motor drive error • Defective motor • Defective sensor • Disconnected connectors or damaged harness • Timing belt, pulley, wires or scanner carriage failure
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 input of the scanner HP sensor (S20) with SP5-803-200. 2. Replace the Scanner HP Sensor (S20), if input check fails. 3. Replace the Scanner Motor (M7). 4. Replace the harness.
