As SC285-00 is a logging SC (SC Type C), it is not displayed at once when an error occurs. Though the equipment can be operated, check the SC history and perform a recovery operation if the SC has occurred.

Countermeasure (1): Large drifting

An abnormal value may be contained in the SP where the MUSIC corrected result is saved.

  1. Execute SP2-180-001 (Line Pos. Adj.: Clear Color Regist.).
  2. Execute SP2-111-004 (Forced Line Position: Adj. Mode d).
  3. Check SP2-194-007 (MUSIC Execution Result: Execution Result).
Countermeasure (2): MUSIC pattern density Error

Execute MUSIC and check the result.

  1. Execute SP3-011-001 (Manual ProCon :Exe : Normal ProCon).
  2. Execute SP2-111-004 (Forced Line Position: Adj. Mode d).
  3. Check SP2-194-007 (MUSIC Execution Result: Execution Result).
Countermeasure (3): Image transfer belt/ Image transfer unit defective
  1. Execute SP2-112-001 (TM/ID Sensor Check: Execute).
  2. Check SP2-112-010 (TM/ID Sensor Check: Display Result: Front-Center-Rear).
    • Normal if the result is "111"
      -->Execute other countermeasures.
    • Vsg adjustment failed if the result is "2xx", "x2x", or "xx2"
      -->Execute recovery operation for SC370
    • There is a high probability that contaminants, scars, or irregularities may exist on the belt if the result is "3xx", "x3x", or "xx3"
      -->Execute the following procedure;
    1. Remove the ITB unit, and check for abnormalities such as contaminants or scars, and set it after cleaning.
    2. Execute SP2-111-004 (Forced Line Position: Adj. Mode d).
    3. Check SP2-194-007 (MUSIC Execution Result: Execution Result).
    4. If it fails, replace the ITB unit.
    • There is a high probability that contaminants or curl may exist on the belt if the result is "5xx", "6xx", "7xx", "8xx", "x5x", "x6x", "x7x", "x8x", "xx5", "xx6", "xx7", or "xx8".
      --> Execute the following procedure
    1. Remove the ITB unit, and check for abnormalities such as contaminants or scars, and set it after cleaning.
    2. Execute SP2-111-004 (Forced Line Position: Adj. Mode d).
    3. Check SP2-194-007 (MUSIC Execution Result: Execution Result).
    4. If it fails, replace the ITB unit.
Countermeasure (4): ID sensor defective

Follow the next step if executing SP2-111-004 (Forced Line Position: Adj. Mode d) and SP2-194-007 (MUSIC Execution Result: Execution Result) fails.

  1. Clean the ID Sensor.
  2. Check the harness and connector for ID sensor.
  3. Replace the ID sensor.
  4. Replace the BiCU.
Countermeasure (5): ID Sensor Shutter Defective

Check if there is no problem concerning the mechanism (interference or deformation).

  1. Execute SP5-804-021 (OUTPUT Check: TM sensor Shutter Solenoid) to operate the ID sensor shutter solenoid to check opening/closing of the shutter.
  2. Check for a broken harness or connector disconnection.
  3. If the problem cannot be solved, replace the BiCU.
