SC496-83CMUSIC Sensor Error: Bend error (Y)
  

Error Condition:
The SC is issued when one of the following errors is occurred.

  • Poor patch number
    (-11: Front, -12: Center, -13: Rear)
  • Belt scratched, smudged
    (-21: Front, -22: Center, -23: Rear, -30: Multi ch)
  • Sub scan registration error
    (-41: Cyan, -42: Magenta, -43: Yellow)
  • Main scan registration error
    (-51: Cyan, -52: Magenta, -53: Yellow)
  • Main scan magnification ratio error
    (-61: Cyan, -62: Magenta, -63: Yellow)
  • Main scan magnification ratio error (Left/Right)
    (-71: Cyan, -72: Magenta, -73: Yellow)
  • Bend error
    (-81: Cyan, -82: Magenta, -83: Yellow)

Error Detection:

  • Executing MUSIC

Details:
Each branch number error determines as follows.

  • Poor patch number
    -> When the patch number is lower than specified.

  • Belt scratched, smudged
    -> When the belt is scratched or smudged in multiple parts.

  • Sub scan registration error
    -> When the correction amount is as follows; fine adjustment: ±1.4 or more, rough adjustment: ±20mm or more.

  • Main scan registration error
    -> When the correction amount is as follows; fine adjustment: ±1.4 or more, rough adjustment: ±15mm or more.

  • Main scan magnification ratio error
    -> When the ratio is ±0.7% or more (outside of the correction table).

  • Main scan magnification ratio error (Left/Right)
    -> When the correction amount is ±32 dot or above.

  • Bend error
    -> When the correction amount is ± (the value of the SP2-190-011) or more.

  • Pattern density abnormal

  • ITB scratched or smudged

  • MUSIC sensor smudged or defective

  • Writing skew motor defective

  • SP value defective

  1. Check the SP2-181-001 (Alignment result: General).

    • Branch numbers 11 to 13: execute step 2.
    • Branch numbers 21 to 30: execute step 3.
    • Branch numbers 41 and more: execute step 2, 3, and 4.

  2. Check the image density. (Execute Density Adjustment)

  3. Check the ITB belt. (Cleaning and replacement)

  4. Check the ID/MUSIC sensor. (Cleaning and replacement)

  5. Replace the laser unit of the applicable color.

SC No.

ITB Temperature/Humidity Sensor Error

One of the following occurred.

  • The temperature sensor output was less than 0.5V or more than 2.8V for three seconds (one second x 3), indicating a problem with the temperature sensor.

  • The humidity sensor output was more than 2.4V for three seconds (one second x 3), indicating a problem with the humidity sensor.

Details:

Detection is repeated after power off/on.

If either of ITB temperature/humidity sensors works correctly, the working sensor will be used even after the SC is issued.

The machine continues working with the assumption that the temperature is 23 degrees centigrade (if there is a problem with the temperature sensor) and/or the humidity is 50% (if there is a problem with the humidity sensor)

  • Connector disconnected or harness broken

  • ITB temperature/humidity sensor defective

  • Connector disconnected or harness broken: Revert connection.

  • ITB temperature/humidity sensor defective: Replace the sensor.
