• Code: C0210
• Description: H. V. abnormal
  - The Drum Charge Monitor Voltage (HVC_MON) signal falls outside a predetermined range at any time after the lapse of a predetermined period of time after the Power Switch has been turned ON.
  - The Image Transfer Voltage Monitor signal (T_MON_V) and Image Transfer Current Monitor signal (T_MON_I) fall outside a corresponding predetermined range
• Remedy: 1 Replace Fusing Unit. 2 Replace PWB-P.

• Code: C0500
• Description: Fuser warm up error
  - The voltage of the Thermistor remains low for a predetermined period of time when a warm-up cycle is started.
  - The temperature detected by the Thermistor remains lower than a reference value for a predetermined period of time for the period of time that begins 5 sec. after, and ends 9 sec. after, the start of the warm-up cycle (where the temperature detected by the Thermistor is 80 °C or less).
  - The temperature detected by the Thermistor does not increase for a 3-sec. period or more for the period of time that begins after the lapse of a predetermined period of time after the Fusing Roller Heater Lamp has been turned ON and ends when the lamp is turned OFF.
  - The Fusing Roller Heater Lamp remains ON for a 30-sec. period or more (except during the period through which the Main Motor remains energized).
• Remedy: 1 Replace Thermistor (TH1). 2 Replace Fusing Unit. 3 Replace Controller/Mechanical Control Board (PWB-P). 4 Replace Power Unit (PU1).

• Code: C0510
• Description: Fuser temperature low
  - The temperature detected by the Thermistor remains lower than the set temperature continuously for a predetermined period of time while the fusing temperature control is being provided. (The set temperatures are as follows: 140 °C during a print mode at 600 dpi; 70 °C during the standby mode.)
• Remedy: 1 Replace Thermistor (TH1). 2 Replace Fusing Unit. 3 Replace Controller/Mechanical Control Board (PWB-P). 4 Replace Power Unit (PU1).

• Code: C0520
• Description: Fuser overheat
  - The temperature detected by the Thermistor remains higher than 235 °C for a predetermined period of time while the fusing temperature control is being provided.
• Remedy: 1 Replace Thermistor (TH1). 2 Replace Fusing Unit. 3 Replace Controller/Mechanical Control Board (PWB-P). 4 Replace Power Unit (PU1).

• Code: C0650
• Description: Scanner home sensor error
  - The Scanner Home Position Sensor is not detected within the predetermined period of time after the Scanner Motor has started turning.
• Remedy: 1 M4 operation check. 2 Replace PWB-P.

• Code: C1200
• Description: ASIC memory abnormal
  - An error occurred while writing to or reading the SRAM on the Control Board (PWB-C).
• Remedy: 1 Turn the copier off, then on again. 2 Check the connection of the memory on the PWB-P, and then correct it if necessary. 3 Replace PWB-P.r unit.

• Code: C1300
• Description: Polygon mirror motor error
  - The LOCK signal is not detected within a predetermined period of time that begins 1 sec. after the Polygon Motor has been energized.
  - No new LOCK signal is detected for a 1-sec. period that begins 1.5 sec. after the first LOCK signal was detected.
  - The LOCK signal is not detected for a continuous 0.5-sec. period in a state in which the Polygon Motor runs stably.
  - The LOCK signal remains ON for a continuous 5-sec. period or more when the Polygon Motor remains deenergized.
• Remedy: 1 Check cables for connection and correct as necessary. 2 Replace PH Unit. 3 Replace PWB-P.
