As SC285-02 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. Execute 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. Execute 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 Test General:FCR).
    • Normal If the result is "111"
      -->Execute other countermeasures.
    • Vsg adjustment is 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 Image Transfer 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. Execute SP2-194-007 (MUSIC Execution Result: Execution Result).
      4. If it fails, replace the Image Transfer Belt/ Image Transfer Unit.
    • There is a high probability that contaminants or curls 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 Image Transfer 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. Execute SP2-194-007 (MUSIC Execution Result: Execution Result).
      4. If it fails, replace the Image Transfer Belt/ Image Transfer Unit.
Countermeasure (4): TM/ID Sensor (S48) 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 TM/ID Sensor (S48).
  2. Check the harness and connector for TM/ID sensor (S48).
  3. Replace the TM/ID sensor (S48).
  4. Replace the BICU (PCB10).
Countermeasure (5): Paper Transfer contact/release Mechanism Defective

Check if the MUSIC/ProCon Pattern is attached on the Paper Transfer Roller. If it is attached, separating may be defective.

  1. Execute SP5-804-255(OUTPUT Check: Paper Transfer Contact Operation) to operate the Paper Transfer Contact Motor to check the separating operation of the Paper Transfer Roller.
  2. Check for a broken harness or connector disconnection.
  3. If the problem cannot be solved, replace the Imaging IOB (PCB2).
Countermeasure (6): Laser Optics Positioning Motor (M23) (M24) (M25) in Laser Unit Error

  1. Check the operation of the laser optics positioning motor (M23) (M24) (M25) and check for a broken harness or connector disconnection. If an abnormality is detected, replace the Laser Unit.

  2. If the problem cannot be solved, replace the Imaging IOB (PCB2).
