• Code: SC400
• Description: ID sensor error: Calibration
  Before adjustment Vsg_reg<0.5 but Vsg_reg could not be adjusted to the target Vsg_reg = 4.0+-0.2V during process control.
• Causes: • ID sensor harness disconnected, loose, defective • ID sensor dirty • ID sensor defective • ITB unit drawer connector dirty

• Code: SC402
• Description: ID Sensor Pattern Maximum Coverage Error 1: K
  The amount of toner applied to create the black ID sensor pattern between sheets (SP3101-1 ID Pattern Display - Applied: K) exceeded the maximum threshold of 0.3 mg/cm2 due to an over supply of black toner.
• Causes: K toner supply unit defective

• Code: SC403
• Description: ID Sensor Pattern Maximum Coverage Error 2: M
  The amount of toner applied to create the magenta ID sensor pattern between sheets (SP3101-2 ID Pattern Display - Applied: M) exceeded the maximum threshold of 0.7 mg/cm2 due to an over supply of magenta toner.
• Causes: • Magenta toner supply unit defective

• Code: SC404
• Description: ID Sensor Pattern Maximum Coverage Error 3: C
  The amount of toner applied to create the cyan ID sensor pattern between sheets (SP3101-3 ID Pattern Display - Applied: C) exceeded the maximum threshold of 0.7 mg/cm2 due to an over supply of cyan toner.
• Causes: • Cyan toner supply unit defective

• Code: SC405
• Description: ID Sensor Pattern Maximum Coverage Error 4: Y
  The amount of toner applied to create the yellow ID sensor pattern between sheets (SP3101-4 ID Pattern Display - Applied: Y) exceeded the maximum threshold of 0.7 mg/cm2 due to an over supply of yellow toner.
• Causes: • Yellow toner supply unit defective

• Code: SC406
• Description: ID Sensor Pattern Minimum Coverage Error 1: K
  The machine detected 10 times that the amount of toner applied to create the black ID sensor pattern on the drum between sheets (SP3101-1 ID Pattern Display - Applied K) was less than the minimum threshold setting (0.0 mg/cm2). Also, the total time for the operation of the sub hopper clutch (SP3251-1 Tnr Supply Time - Sub Hopper CL: K) was less than or equal to the threshold of 65K ms.
• Causes: • Toner shield glass dirty • Development unit defective • Image transfer unit defective

• Code: SC407
• Description: ID Sensor Pattern Minimum Coverage Error 2: M
  The machine detected 10 times that the amount of toner applied to create the magenta ID sensor pattern on the drum between sheets (SP3101-2 ID Pattern Display - Applied M) was less than the minimum threshold setting (0.2 mg/cm2). Also, the total time for the operation of the sub hopper clutch (SP3251-2 Tnr Supply Time - Sub Hopper CL: M) was less than or equal to the threshold of 65K ms.
• Causes: • Toner shield glass dirty • Development unit defective • Image transfer unit defective

• Code: SC408
• Description: ID Sensor Pattern Minimum Coverage Error 3: C
  The machine detected 10 times that the amount of toner applied to create the cyan ID sensor pattern on the drum between sheets (SP3101-3 ID Pattern Display - Applied C) was less than the minimum threshold setting (0.2 mg/cm2). Also, the total time for the operation of the sub hopper clutch (SP3251-3 Tnr Supply Time - Sub Hopper CL: C) was less than or equal to the threshold of 65K ms.
• Causes: • Toner shield glass dirty • Development unit defective • Image transfer unit defective
