Error Codes List page 1

  • Code: 901
  • Description: Upper total counter error • Feedback signal stays LOW when the main switch turns on. • Feedback signal stays LOW just before the trigger signal goes ON. • Feedback signal stays HIGH just before the trigger signal goes off.
  • Causes:
  • Remedy: 1. Check if the connectors are properly set. 2. Replace the total counter.
  • Code: 902
  • Description: Lower total counter error • Feedback signal stays LOW when the main switch turns on. • Feedback signal stays LOW just before the trigger signal goes ON. • Feedback signal stays HIGH just before the trigger signal goes off.
  • Causes:
  • Remedy: 1. Check if the connectors are properly set. 2. Replace the total counter.
  • 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 (FU103) • Defective lamp regulator • Poor connection of cables • Defective cables • Defective scanner IPU board • Defective PSU
  • 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 the 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 cables. 5. Replace the lamp regulator if 100Vac is present at the CN3-1 and 5 on the lamp regulator. 6. Replace the scanner IPU board - Signals to Check - • LAMPDET: CN502-2 on lamp regulator / CN403-12 on scanner IPU board • LAMPTRIG: CN403-11 on scanner IPU board / CN502- 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 CN406-7 stays HIGH (5V).
  • Causes: • Scanner motor out of synchronization (drive error) • Poor connection of connectors • Defective scanner HP sensor • Defective 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 CN710, and CN731 on the scanner motor drive board. 5 Check continuity of cables. 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 cable is properly connected. 2 Check the continuity of cable. 3 Replace the sensor. 4 Replace the scanner IPU board. 5 Replace the main control board. - Signals to Check - • Scanner HP: CN406-7 on 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 CN406- 7stays LOW (0V).
  • Causes: • Scanner motor out of synchronization (drive error) • Poor connection of connectors • Defective scanner HP sensor • Defective 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 CN710, and CN731 on the scanner motor drive board. 5 Check continuity of cables. 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 cable is properly connected. 2 Check the continuity of cable. 3 Replace the sensor. 4 Replace the scanner IPU board. 5 Replace the main control board. - Signals to Check - • Scanner HP: CN406-7 on scanner IPU board
  • Code: SC130
  • Description: Scanner start error - Timing - • Scanning start • While the scanner motor is running - Condition - The scanning start signal is generated while the motor is moving. Total number of steps calculated based on the signal from the stepper motor is out of range. The H.P. sensor stays off when the scanner starts moving. A ‘scan start’ command was issued while the motor was active.
  • Causes: • Scanner motor out of synchronization (drive error) • Poor connection of connectors • Defective scanner HP sensor • Defective 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 CN710, and CN731 on the scanner motor drive board. 5 Check continuity of cables. 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 cable is properly connected. 2 Check the continuity of cable. 3 Replace the sensor. 4 Replace the scanner IPU board. 5 Replace the main control board. - Signals to Check - • Scanner HP: CN406-7 on scanner IPU board or Replace the sub and/or main scanner IPU board(s).
