• Code: 302
• Description: Charge roller error
  A charge roller current leak signal is detected.
• Causes: • Charge high voltage supply board defective • Connection at PCU loose, disconnected, or damaged

• Code: 320
• Description: Polygon motor error
  • The XSCRDY signal did not activate (go LOW) within 10 sec. after the polygon motor turned on. • The XSCRDY signal did not deactivate (go HIGH) within 3 sec. after the polygon motor turned off. • The polygon motor continued to rotate for the prescribed number of rotations for 200 ms after the XSCRDY signal went HIGH (deactivated). • After the polygon motor turned on, or after the machine detected that the prescribed number of rotations had changed, the XSCRDY signal did not go LOW (active).
• Causes: • Polygon motor I/F harness loose, disconnected, or defective • Polygon motor defective • Polygon motor driver defective • SBCU board defective

• Code: 322
• Description: Laser synchronization error
  The main scan synchronization detector board cannot detect the laser synchronization signal for more than 10 consecutive 50 ms intervals.
• Causes: • Poor connection between the laser synchronization detector board and the SBCU board • Laser synchronization detector board out of position • Laser synchronization detector board defective • SBCU board defective • LD unit defective

• Code: 323
• Description: LD drive current over
  • The LD drive current exceeded 100 mA. • The XLDERR of the LD board was detected LOW twice within 100 ms. • Initialization of the PMACA failed.
• 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 - 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 - 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
