Description: Polygonal Mirror Motor Error 4: Unstable Timeout
The XSCRDY signal is detected LOW) (Active) after the polygonal mirror motor switches on, but the signal is not detected LOW after 1 s has elapsed, and not detected after another 500 ms has elapsed.
Causes: • I/F harness of the polygonal mirror motor disconnected or defective. • Polygonal mirror motor or polygonal mirror motor driver defective. • Polygonal mirror motor drive pulse is not output incorrectly. • GABIC cannot monitor XSCRDY signal.
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 >=2.5V 2) Vsg <= 2.5V 3) Vsp = 0V 4) Vsg = 0V
Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • ID sensor dirty • Defect at ID sensor pattern writing area of the drum
Code: 351
Description: ID sensor Vsg test error
When the ID sensor was checked, the ID sensor output voltage was 5.0V while the PWM signal input to the ID sensor was 0.
Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connection • I/O board (IOB) defective • Scanning system defective • High voltage supply board defective • ID sensor dirty • Defect at the ID sensor pattern writing area of the drum
Code: 352
Description: ID sensor, pattern edge detect error
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: 353
Description: ID sensor, LED current abnormal at initialization
• 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 harness defective • ID sensor connector defective • Poor ID sensor connection • I/O board (IOB) defective • Exposure system defective • High voltage supply board defective • Dirty ID sensor
Code: 354
Description: ID sensor timeout abnormal at adjustment
Vsg falls out of the adjustment target (4.0 +- 0.2V) at the start of Vsg checking after 20 seconds
Causes: • ID sensor defective • ID sensor harness defective • ID sensor connector defective • I/O board (IOB) defective • Exposure system defective • Poor ID sensor connector connection • High voltage supply board defective • Dirty ID sensor
