• Code: SC350-3
• Description: ID sensor error 3
  The ID sensor pattern edge voltage is detected to be not 2.5V twice consecutively during an 800 ms interval.
• Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • Dirty ID sensor • Defect at the ID sensor pattern writing area of the drum

• Code: SC350-4
• Description: ID sensor error 4
  One of the following ID sensor output voltages is detected at ID sensor initialization. 1) Vsg < 4.0V when the maximum PWM input (255) is applied to the ID sensor. 2) Vsg >= 4.0V when the minimum PWM input (0) is applied to the ID sensor.
• Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • Dirty ID sensor • Defect at the ID sensor pattern writing area of the drum

• Code: SC350-5
• Description: ID sensor error 5
  Vsg falls out of the adjustment target (4.0+- 0.2V) during Vsg checking.
• Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • Dirty ID sensor • Defect at the ID sensor pattern writing area of the drum

• Code: SC360
• Description: Hard disk drive error 1
  The machine does not detect the connection signal from the HDD.
• Causes: • Poor connection between the HDD and HDD controller board • The ac power connector to the HDD is disconnected. • HDD defective • HDD controller board defective • BICU defective

• Code: SC361
• Description: Hard disk drive error 2
  The image data stored in the HDD cannot be output properly.
• Causes: When this SC occurs only once, this problem will be solved after turning the main power switch off and on. • When this SC occurs while performing SP4-911-1 (HDD media check), it can be cured by doing SP4-911-2 (HDD formatting). • HDD defective

• Code: SC362
• Description: IMAC (image compression IC) error
  An error occurs during image processing in the IMAC, which handles image compression and image data transmission.
• Causes: • BICU defective • HDD controller board defective

• Code: SC365
• Description: Image storage address error
  The BICU receives an image data output request signal for data that is not stored in memory.
• Causes: • BICU defective

• Code: SC390-1
• Description: TD sensor error 1
  The TD sensor output voltage is less than 0.5V or more than 5.0V 10 consecutively during copying.
• Causes: • TD sensor abnormal • Poor connection between the TD sensor and the I/O board (IOB) • I/O board (IOB) defective
