Error Codes List page 1

  • Code: SC101
  • Description: Exposure lamp failure - Timing & Condition - • The lamp output check signal (LAMPDET) is still HIGH 250 ms after the lamp turns on (the ON check is canceled if the lamp goes off within 250 ms). • The lamp output check signal is still LOW 30ms after the lamp turns off (the OFF check is canceled if the lamp turns on within 30 ms).
  • Causes: • Blown lamp • Blown thermostat • Blown fuse (FU301) • Defective lamp regulator • Poor connection of harnesses • Defective harnesses • Defective AC drive board • Defective sub/main scanner IPU board
  • Remedy: 1. Visually check the lamp element or check the continuity between both ends of the lamp terminals with a multimeter. 2. Check continuity at the ends of he thermostat terminals with a multi-meter. 3. Check if the connectors (CN1, CN2, and CN3) on the lamp regulator are properly connected. 4. Check the continuity of the 3 harnesses. 5. Replace the lamp regulator if 100Vac is provided from the AC drive board by checking CN3-1 and 5 on the lamp regulator. 6. Replace the AC drive board if 100Vac is not supplied at CN3 on the lamp regulator. 7. Replace the sub scanner IPU board and/or main scanner IPU board [ Signal Check ] • LAMPDET: CN2-2 on lamp regulator / CN403-A10 on sub scanner IPU board • LAMPTRIG: CN403-A9 on sub scanner IPU board / CN2-3 on lamp regulator
  • Code: SC120
  • Description: Scanner HP sensor does not turn on - Timing & Condition - The scanner H.P. sensor does not turn on when the scanner moves back to the home position or at the home position check. The sensor output at CN403-A1 stays HIGH (5V).
  • Causes: • Scanner motor out of synchronization (drive error) • Poor connection of connectors • Defective scanner HP sensor • Defective sub/main scanner IPU board • Defective main control board
  • Remedy: 1. In SP 5-804-104, stop supplying the current to the scanner motor. Check the output signal from the scanner H.P. sensor in SP 5-803-100 by moving the scanner manually. (0: Not actuated; 1: Actuated - at H.P.) 2. If the result of step 1 is OK; 1 Check the tension of the timing belt. 2 Check if the pulley is firmly secured. 3 Check if the scanner wire is properly wired 4 Check the connection of CN700, CN701, and CN702 on the scanner motor drive board. 5 Check continuity of harnesses. 6 Replace the scanner motor drive board. 7 Replace the scanner motor. 3. If the result of step 1 is not OK; 1 Check if the harness is properly connected. 2 Check the continuity of harness. 3 Replace the sensor. 4 Replace the sub and/or main scanner IPU board(s). 5 Replace the main control board. [ Signal Check ] • Scanner HP: CN403-A1 on sub scanner IPU board
  • Code: SC121
  • Description: Scanner HP sensor does not turn off - Timing & Condition - The sensor does not turn off when the scanner moves to the home position after scanning an original. The sensor output at CN403-A1 stays LOW (0V).
  • Causes: • Scanner motor out of synchronization (drive error) • Poor connection of connectors • Defective scanner HP sensor • Defective sub/main scanner IPU board • Defective main control board
  • Remedy: 1. In SP 5-804-104, stop supplying the current to the scanner motor. Check the output signal from the scanner H.P. sensor in SP 5-803-100 by moving the scanner manually. (0: Not actuated; 1: Actuated - at H.P.) 2. If the result of step 1 is OK; 1 Check the tension of the timing belt. 2 Check if the pulley is firmly secured. 3 Check if the scanner wire is properly wired 4 Check the connection of CN700, CN701, and CN702 on the scanner motor drive board. 5 Check continuity of harnesses. 6 Replace the scanner motor drive board. 7 Replace the scanner motor. 3. If the result of step 1 is not OK; 1 Check if the harness is properly connected. 2 Check the continuity of harness. 3 Replace the sensor. 4 Replace the sub and/or main scanner IPU board(s). 5 Replace the main control board. [ Signal Check ] • Scanner HP: CN403-A1 on sub scanner IPU board
  • Code: SC130
  • Description: Scanner start error - Timing - • Scanning start • During scanner motor ON - Condition - The scanning start signal is generated while the motor is moving. Total number of steps calculated based on the signal from the stepping motor is out of range. The H.P. sensor stays OFF when the scanner starts moving.
  • Causes: • Scanner motor out of synchronization (drive error) • Poor connection of connectors • Defective scanner HP sensor • Defective sub/main scanner IPU board • Defective main control board
  • Remedy: 1. In SP 5-804-104, stop supplying the current to the scanner motor. Check the output signal from the scanner H.P. sensor in SP 5-803-100 by moving the scanner manually. (0: Not actuated; 1: Actuated - at H.P.) 2. If the result of step 1 is OK; 1 Check the tension of the timing belt. 2 Check if the pulley is firmly secured. 3 Check if the scanner wire is properly wired 4 Check the connection of CN700, CN701, and CN702 on the scanner motor drive board. 5 Check continuity of harnesses. 6 Replace the scanner motor drive board. 7 Replace the scanner motor. 3. If the result of step 1 is not OK; 1 Check if the harness is properly connected. 2 Check the continuity of harness. 3 Replace the sensor. 4 Replace the sub and/or main scanner IPU board(s). 5 Replace the main control board. [ Signal Check ] • Scanner HP: CN403-A1 on sub scanner IPU board or Replace the sub and/or main scanner IPU board(s).
  • Code: SC150
  • Description: Scanner ROM mismatch - Timing - After software installation or when the main switch turned on - Condition - Main scanner IPU detects that the software installed is not specific one.
  • Causes: • An invalid IC card used (such as a different model IC card) • Replace the main scanner IPU board.
  • Remedy: Reinstall the correct IC card. Replace the main scanner IPU board.
  • Code: SC170
  • Description: Video processing error 1 - Timing - When the main switch is turned on (after auto gain control at scanner IPU board) - Condition - The black level corrected between the Odd and Even (O/E) of the CCD is not in the proper range.
  • Causes: • Poor connection of CCD flat cable • Defective Scanner IPU board • Defective CCD
  • Remedy: 1. Check if the flat cable is firmly connected at CN501 and CN404 on the CCD board and main scanner IPU board. 2. Check the continuity of the flat cable. 3. Replace main scanner IPU board. 4. Replace CCD board as the lens unit assembly.
