Description: Original exit roller thermistor error The original exit roller thermistor reading was abnormal.
Causes: • Thermistor connection loose, broken, defective • Thermistor short • Harness between thermistor and IOB loose, broken, defective • IOB defective • BCU defective
Remedy:
Code: SC300
Description: Charge corona output error Charge corona feedback voltage less than 0.5 V was detected for more than 200 sec after power on.
Causes: • TD power pack defective. • High voltage cable defective. • Dirty charge corona wire caused voltage leak
Remedy:
Code: SC303
Description: Charge grid output error Control PWM duty value is higher than 1% (FB less than 1V) for more than 200 ms due to grid current leak.
Causes: • CGB power pack is defective. • CGB power pack harness loose, broken, defective
Remedy:
Code: SC305
Description: Charge corona wire cleaner error The wire cleaning pad did not return to its home position within 5 sec. after wire cleaning.
Causes: • Wire cleaner motor harness loose, broken, defective • Wire cleaner motor defective • Charge corona wire defective
Remedy: • This SC is not issued if SP2804 is set to zero (no cleaning). • If immediate repair is not possible, set SP2804 to zero to switch off the charge corona cleaner function.
Code: SC347
Description: Development drive motor lock error Development drive motor stopped (the lock signal remained HIGH longer than 5 sec. when the development was operating).
Causes: • Motor or drive mechanism blocked • Motor harness loose, broken, defective • Motor defective
Remedy:
Code: SC392
Description: Development bias error The PWM duty level was detected higher than 5% within 100 ms after high voltage output started, and the feedback voltage was detected less than 0.3 V for more than 200 ms.
Causes: • Harness connection between CGB power pack and IOB loose, broken, defective • CGB power defective • High voltage cable damaged
