• Code: E025-0000
• Description: The hopper motor or the bottle motor is faulty.
  The sub hopper toner sensor connection detection signal is absent for 100 msec 10 times in sequence.
• Remedy: Replace the sub hopper toner sensor. Connect the connector. Replace the detection PCB.

• Code: E025-0001
• Description: The hopper motor or the bottle motor is faulty.
  While the hopper motor is rotating, the motor error lock signal is detected continuously 4 times every 56 msec. Or, while the bottle motor is rotating, the motor error lock signal is detected 22 times in sequence every 10 msec.
• Remedy: Replace the hopper motor. Replace the bottle motor. Replace the DC controller PCB.

• Code: E032-0001
• Description: The NE controller counter malfunctions.
  An open circuit is detected for the count pulse signal.
• Remedy: Turn off the main power, and check the cable for an open circuit; then, turn the main power back on.

• Code: E064-0001
• Description: The voltage of the power supply is faulty (high-voltage error).
  The value read from the EEPORM is outside a specific range.
• Remedy: Turn off and then back on the main power. Replace the EEPROM.

• Code: E064-0002
• Description: The voltage of the power supply is faulty (high-voltage error).
  While output is being generated, the AD value of the primary DC voltage is 230 (DEC) or more for 100 msec 2 times in sequence. (However, after output, it is not detected for 100 msec.)
• Remedy: Replace the high-voltage power supply. Replace the DC controller PCB.

• Code: E064-0003
• Description: The voltage of the power supply is faulty (high-voltage error).
  While output is being generated, the AD value of the developing DC voltage is 224 (DEC) or more for 10 msec 2 times in sequence. (However, after output, it is not detected for 100 msec.)
• Remedy: Replace the high-voltage power supply. Replace the DC controller PCB.

• Code: E064-0004
• Description: The voltage of the power supply is faulty (high-voltage error).
  While output is being generated, the AD value of the transfer output current is 205 (DEC) or more for 100 msec 2 times in sequence. (However, after output, it is not detected for 100 msec.)
• Remedy: Replace the high-voltage power supply. Replace the controller PCB.

• Code: E064-0005
• Description: The voltage of the power supply is faulty (high-voltage error).
  While output is being generated, the AD value of the transfer output voltage is 0 (DEC) for 100 msec 2 times in sequence. (However, after output, it is not detected for 100 msec.)
• Remedy: Replace the high-voltage power supply. Replace the DC controller PCB.
