• Code: 323
• Description: LD drive current over
  The LD drive board applies more than 100 mA to the LD.
• Causes: • LD unit defective (not enough power, due to aging) • Poor connection between the LD unit and the SBCU board • SBCU board defective

• Code: 350
• Description: ID sensor calibration - Error 1
  One of the following conditions occurred when the ID sensor pattern was calibrated during printing: • Vsp > 2.5V • Vsg < 2.5V • Vsp = 0V • Vsg = 0V
• Causes: • ID sensor defective or dirty • ID sensor harness disconnected or connector is damaged • SBCU defective • Scanning system or image creation system malfunction • High voltage power supply board (power pack) defective

• Code: 351
• Description: ID sensor calibration œ Error 2
  The following conditions occurred simultaneously when the ID sensor pattern was calibrated during printing: • Vsg = 5V • PWM = 0 (LED current drop)
• Causes: • ID sensor dirty or defective • ID sensor harness disconnected, or connector damaged • SBCU board defective • High voltage power supply board (power pack) defective

• Code: 352
• Description: ID sensor calibration œ Error 3
  During printing the 2.5V value for edge detection of the ID sensor pattern could not be detected after 800 ms.
• Causes: • ID sensor dirty or defective • ID sensor harness disconnected, or connector damaged • SBCU defective • High voltage power supply board (power pack) defective

• Code: 353
• Description: ID sensor adjustment Error 1
  Error occurred during automatic adjustment of Vsg: • Vsg output did not attain 4V, even with PWM = 255 (maximum current for LED) • Vsg output was greater than 4V, even with PWM=0 (no current for the LED)
• Causes: • ID sensor dirty or defective • ID sensor harness disconnected, or connector damaged • SBCU defective • High voltage power supply board (power pack) defective • Scanning system or image creation system malfunction

• Code: 354
• Description: ID Sensor Adjustment Error 2
  Error occurred during automatic adjustment of Vsg. Vsg could not be adjusted to 4.0V±0.2V within 50 ms even after 20 attempts.
• Causes: • ID sensor dirty or defective • ID sensor harness disconnected, or connector damaged • SBCU defective • High voltage power supply board (power pack) defective • Scanning system or image creation system malfunction

• Code: 355
• Description: ID sensor error
  For details about the cause of the problem, please refer to SC350~354 above.
• Causes: • ID sensor dirty or defective • ID sensor harness disconnected, or connector damaged • SBCU board defective • High voltage power supply board (power pack) defective • Scanning system or image creation system malfunction

• Code: 389
• Description: TD sensor error
  TD sensor output was less than 0.5V, or more than 0.5V 10 times in succession. If the fax unit is installed, this SC is issued immediately. If the fax unit is not installed, this SC is issued after the prescribed number of copies has printed.
• Causes: • TD sensor defective • TD sensor connector damaged.
