• Code: 300
• Description: Charge Corona Output Error After sampling at 10 ms intervals, the charge-corona feedback voltage remained less than 0.5 V for more than 200 ms.
• Causes: • Charge corona unit defective • High voltage cable defective • Corona wire dirty or defective • CGB power pack fuse, connections loose, broken, or defective • CGB power pack defective
• Remedy:

• Code: 305
• Description: Charge Corona Wire Cleaner Error The charge wire cleaner did not: (1) come from the home position within 5 s, or (2) did return to the home position within 3.75 s due to wire cleaner overload.
• Causes: • Cleaner unit blocked or damaged • Until replacement parts become available, set SP2804 to "0" to disable the charge-corona cleaning function so the machine can operate.
• Remedy:

• Code: 392
• Description: Development Bias Error The development bias feedback voltage was less than 0.3 V for longer than 200 ms while the PWM duty value was more than 5% (indicating a development bias leak).
• Causes: • Bias terminal damaged • High voltage cable damaged, defective • CGB power pack defective
• Remedy:

• Code: 400
• Description: ID Sensor Auto Adjustment Error. Vsg did not reach 4 ±0.2 V when the ID sensor was initialized with SP3001-2.
• Causes: • ID sensor dirty • ID sensor harness, connector loose, disconnected, damaged, defective • ID sensor defective • MCU defective • Development unit defective • CGB power pack defective
• Remedy:

• Code: 401
• Description: ID Sensor Vsg Error The Vsg level was twice detected lower than 2.5 V. -or- The Vsg level was once detected higher than 4.8V.
• Causes: • ID sensor dirty • ID sensor harness, connector loose, disconnected, damaged, defective • ID sensor defective • MCU defective • CGB power pack defective
• Remedy:

• Code: 402
• Description: ID Sensor Vsp Error The Vsp level was twice detected at 0V or at more than 2.5 V.
• Causes: • Under the left upper cover, make sure that the hex screw of the main drum drive gear is tight • ID sensor dirty • ID sensor harness, connector loose, disconnected, damaged, defective • ID sensor defective • MCU defective • Development unit defective • CGB power pack defective
• Remedy:

• Code: 440
• Description: Transfer Output Error. A high voltage feedback voltage of less than 0.5 V was detected for 200 ms.
• Causes: • High voltage cable disconnected, damaged • T/S power pack defective
• Remedy:

• Code: 460
• Description: DC Separation Corona Output Error A dc separation feedback voltage of less than 0.5 V was detected after more than 200 ms.
• Causes: • High voltage cable disconnected, damaged • T/S power pack defective
• Remedy:
