• Code: E020-0001
• Description: There is no toner in the developing assembly; there is an error in the detection of developing toner sensor connection; there is an error in the detection of hopper toner sensor connection.
  At power-on, the connection of the developing assembly toner sensor is not detected.
• Remedy: - Check the connector for any fault in connection. - Replace the sensor.

• Code: E020-0002
• Description: There is no toner in the developing assembly; there is an error in the detection of developing toner sensor connection; there is an error in the detection of hopper toner sensor connection.

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

• Code: E061-0001
• Description: There is a potential control error/there is an APC error.
  As a result of potential control, the drum surface potential (VL2) of the background is 200 V or higher (i.e., causing a solid black image).
• Remedy: - Replace the potential sensor unit. - Replace the laser scanner unit. - Replace the DC controller PCB.

• Code: E061-0002
• Description: There is a potential control error/there is an APC error.
  The primary charging output used at time of printer output and the drum surface potential after laser output is identified as being 200 V or more (i.e., causing a solid black image).
• Remedy: - Replace the potential sensor unit. - Replace the laser scanner unit. - Replace the DC controller PCB.
