Description: Scanner Home Position Error 2 The Scanner HP Sensor (S20) did not go ON : • During homing operation • During auto adjustment • During document, book scanning
Causes: • Motor drive error • Defective Scanner Motor (M7) • Defective Scanner HP Sensor (S20) • Disconnected connectors or damaged harness • Timing belt, pulley, wires or 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.
Code: SC141-00
Description: Black Level Detection Error Black level is not less than the prescribed value. This SC is detected when: the scanner power is turned on and the machine returns from the energy saver 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: • SBU (PCB11) - BiCU harness (FFC) 2. Replace the scanner carriage 3. Replace the BiCU (PCB1). 4. Replace the harness (FFC).
Code: SC142-00
Description: White Level Detection Error The white peak level cannot be in the prescribed value when adjusting the scanner gain. This SC is detected when the scanner power is turned on and the machine returns from the energy saver mode.
Causes: • Condensation in scanner unit • Scanner carriage defective • BiCU defective • Harness defective • Connector defective (disconnected, loose) • 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 white plate that is used for shading adjustment. This plate is attached to the back 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: SC144-00
Description: SBU Communication Error The machine cannot detect that the SBU (PCB11) is connected.
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) 2. Replace the scanner carriage. 3. Replace the BiCU (PCB1). 4. Replace the following harness: • Scanner Carriage - BiCU (PCB1) (FFC)
Code: SC151-00
Description: Black Level Correction Error: Rear Side The automatic adjustment has failed to correct the black level (rear side) to the permissible range.
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: • CIS (S21) - BiCU harness (FFC) 2. Replace the CIS (S21). 3. Replace the BiCU (PCB1). 4. Replace the harness (FFC).
Code: SC152-00
Description: White Level Correction Error: Rear Side The automatic adjustment has failed to correct the white level (rear side) to the permissible range.
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 BiCU (PCB1). 5. Replace the harness (FFC).
