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
Remedy:
Code: SC400
Description: ID sensor error 1: automatic adjustment error During the process control self-check, the Vsg value (reflectivity of the bare drum surface) could not be adjusted to within 4.0±0.2V within 20 sec. after automatic adjustment began.
Causes: • ID sensor dirty • ID sensor harness loose, broken, defective • ID sensor harness connection at IOB loose, broken, defective. • ID sensor defective • Exposure unit defective • Development unit defective • TD power pack defective
Remedy:
Code: SC401
Description: ID sensor error 2: Vsg When the ID sensor was calibrated, Vsg (reflectivity of the bare drum surface) was detected less than 2.5V after two attempts. -or- After calibration, Vsg was detected as 5.0V at PWM adjustment and PWM=0.
Causes: • Dirty ID sensor • ID sensor harness connection loose, broken, defective • TD power pack defective • IOB defective
Remedy:
Code: SC402
Description: ID sensor error 3: Vsp The Vsp (reflectivity of ID sensor pattern) value was detected at "0" or more than 2.5V when the ID sensor was calibrated during process control.
Causes: • OPC drum gear Allen screw loose • ID sensor dirty • ID sensor harness loose, broken, defective • ID sensor defective • IOB defective • Exposure unit defective • Development unit defective • TD power pack defective
Remedy:
Code: SC403
Description: ID sensor error 4: LED current error During Vsg adjustment (reflectivity of the bare drum surface) during process control, the averaged PWM output was zero or 255.
Causes: • ID sensor dirty • ID sensor harness connection loose, broken, defective • ID sensor defective • IOB defective • Exposure unit defective • Development unit defective • TD power pack defective
