• Code: 335
• Description: Polygon motor error 1: On timeout
  The XSCRDY signal did not go LOW (Active) within 10 sec. after the polygon motor was turned on.
• Causes: • Polygon motor drive board I/F harness loose, disconnected, or damaged • Polygon motor drive board defective • Polygon motor defective

• Code: 336
• Description: Polygon motor error 2: Off timeout
  The XSCRDY signal did not go HIGH (Inactive) within 3 sec. after the polygon motor was turned off.
• Causes: • Polygon motor drive board I/F harness loose, disconnected, or damaged • Polygon motor drive board defective • Polygon motor defective

• Code: 337
• Description: Polygon motor error 3: XSCRDY signal error
  The XSCRDY signal did not go HIGH (Inactive) after the polygon motor had been rotating normally for 200 ms.
• Causes: • Polygon motor drive board I/F harness loose, disconnected, or damaged • Polygon motor drive board defective • Polygon motor defective

• Code: 338
• Description: Polygonal Mirror Motor Error 4: Unstable Timeout
  The XSCRDY signal was detected LOW) (Active) after the polygonal mirror motor switched on, but the signal was not detected LOW after 1 sec., and was not detected after another 500 ms.
• Causes: • I/F harness of the polygonal mirror motor disconnected or defective. • Polygonal mirror motor or polygonal mirror motor drive board defective.

• Code: 350
• Description: ID sensor pattern test error
  One of the following ID sensor output voltages was detected twice consecutively when checking the ID sensor pattern. 1. Vsp greater/equal 2.5V 2. Vsg less than/equal 2.5V 3. Vsp = 0V 4. Vsg = 0V
• Causes: • ID sensor defective • ID sensor harness or connector loose, broken, defective • IOB defective • HVPS board defective • ID sensor dirty

• Code: 351
• Description: ID sensor Vsg measurement error
  When the ID sensor was checked twice, the ID sensor output voltage was 5.0V while the PWM signal input to the ID sensor was 0.
• Causes: • ID sensor connector or harness loose, broken, or defective • ID sensor defective • IOB defective • HVPS defective • ID sensor dirty

• Code: 352
• Description: ID sensor pattern edge detection error
  The ID sensor pattern edge voltage was not equal to 2.5 V and two samplings within 800 ms.
• Causes: • ID sensor connector or harness loose, broken, or defective • ID sensor defective • IOB defective • HVPS defective • ID sensor dirty

• Code: 353
• Description: ID sensor, LED current abnormal at initialization
  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) was applied to the ID sensor. • Vsg exceeded 4.0V when the minimum PWM input (0) is applied to the ID sensor.
• Causes: • ID sensor connector or harness loose, broken, or defective • ID sensor defective • IOB defective • HVPS defective • ID sensor dirty
