• Code: 350
• Description: ID sensor error 1
  One of the following ID sensor output voltages was detected twice consecutively when checking the ID sensor pattern. Vsp greater than or equals 2.5V Vsg less than 2.5 Vsp = 0V Vsg = 0
• Causes: • ID sensor defective • ID sensor harness disconnected • ID sensor connector defective • IOB defective • ID sensor pattern not written correctly • Incorrect image density • Charge power pack defective • ID sensor dirty

• Code: 351
• Description: ID sensor error 2
  The ID sensor output voltage is 5.0V and the PWM signal input to the ID sensor is 0 when checking the ID sensor pattern
• Causes: • ID sensor defective • ID sensor harness disconnected • ID sensor connector defective • IOB defective • ID sensor pattern not written correctly • Incorrect image density • Charge power pack defective • ID sensor dirty

• Code: 352
• Description: ID sensor error 3
  For 2 s during the ID sensor pattern check, the ID sensor pattern edge voltage is not 2.5V or the pattern edge is not detected within 800 ms.
• Causes: • ID sensor defective • ID sensor harness disconnected • ID sensor connector defective • IOB defective • ID sensor pattern not written correctly • Incorrect image density • Charge power pack defective • ID sensor dirty

• Code: 353
• Description: ID sensor error 4
  One of the following ID sensor output voltages is detected at ID sensor initialization. Vsg less than 4.0V when the maximum PWM input (255) is applied to the ID sensor. Vsg greater than or equal to 4.0V when the minimum PWM input (0) is applied to the ID sensor.
• Causes: • ID sensor defective • ID sensor harness disconnected • ID sensor connector defective • IOB defective • ID sensor pattern not written correctly • Incorrect image density • Charge power pack defective • ID sensor dirty

• Code: 354
• 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 harness disconnected • ID sensor connector defective • IOB defective • ID sensor pattern not written correctly • Incorrect image density • Charge power pack defective • ID sensor dirty

• Code: 355
• Description: ID sensor error 6
  The Vp value, which measures the reflectivity of the ID sensor pattern, was not in the range of -70V to -400V.
• Causes: • Potential sensor defective • Potential sensor harness defective • Potential sensor disconnected • IOB defective • OPC unit connector defective • Charge corona power pack defective • Charge corona wire dirty, broken

• Code: 401
• Description: Transfer output abnormal
  When the transfer is output, the feedback voltage remains higher than 4V for 60 ms.
• Causes: • Transfer power pack defective • Transfer current terminal, transfer power pack disconnected, damaged connector

• Code: 402
• Description: Transfer output abnormal release detection
  When the transfer is output, there is hardly any feedback voltage within 60 ms even with application of 24% PWM.
• Causes: • Transfer power pack defective • Transfer unit harness disconnected • Transfer connector loose, defective
