Imaging IOB malfunction
Solutions
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 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.
2. Check the harness and connector for TM/ID sensor.
3. Replace the TM/ID sensor.
4. Replace the BCU.
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 and release motor to check the separating operation of the paper transfer roller.
