• Code: 559-00
• Description: Fusing jam detected 3 times in succession
  Fusing jam is detected three times in succession.
• Causes: Paper is wrapped around the fusing roller.
• Remedy: CLEAR THE SP: FUSING SC.

• Code: 561-00
• Description: Broken pressure (Center) thermistor wire
  At least ten times, the temperature is detected to stay at 0 deg C or less for three seconds.
• Causes: - Broken thermistor wire - Bad connector contact
• Remedy: • CLEAR THE SP: FUSING SC. • Check the connector connection. • Replace the fusing (End) thermistor.

• Code: 562-00
• Description: Pressure (Center) thermistor not reloaded
  The pressure (Center) thermistor does not reach 40 deg C 17.8 seconds after the start of heat control (during normal startup control).
• Causes: • Stained thermopile lens • Deformed or floating thermistor • Input voltage out of range • The overtemperature prevention mechanism started working
• Remedy: • CLEAR THE SP: FUSING SC. • Replace the Fusing Unit.

• Code: 563-00
• Description: Pressure (Center) thermistor high-temperature detected (software)
  The temperature is detected to stay at 230 deg C or higher for one second.
• Causes: • Shorted triac • Failed Engine Board
• Remedy: • CLEAR THE SP: FUSING SC. • Replace the PSU. • Replace the Engine Board.

• Code: 564-00
• Description: Pressure (Center) thermistor high-temperature detected (hardware)
  The pressure (Center) thermopile temperature becomes 250 or higher. (The hardware high-temperature error Sensor flag is detected at 10 ms intervals.)
• Causes: • Damaged triac (shorted) • Failed Engine Board • Failed fusing thermopile • Failed fusing thermistor • Abnormal fusing control software behavior • The PWM signal is continuously supplied from the IH inverter (due to a software or temperature Sensor error).
• Remedy: • CLEAR THE SP: FUSING SC. • Replace the PSU. • Replace the Engine Board. • Replace the fusing thermopile. • Replace the Fusing Unit.

• Code: 571-00
• Description: Broken pressure (End) thermistor wire At least ten times, the temperature is detected to stay at 0 deg C or less for three seconds.
• Causes: - Broken thermistor wire - Bad connector contact
• Remedy: • CLEAR THE SP: FUSING SC. • Check the connector connection. • Replace the fusing (End) thermistor.

• Code: 573-00
• Description: Pressure (Center) thermistor high-temperature detected (software)
  The temperature is detected to stay at 230 deg C or higher for one second.e seconds
• Causes: • Shorted triac • Failed Engine Board
• Remedy: • CLEAR THE SP: FUSING SC. • Replace the PSU. • Replace the Engine Board.

• Code: 574-00
• Description: Pressure (End) thermistor high
  The pressure (Center) thermopile temperature becomes 250 deg C or higher. (The hardware high)
• Causes: • Damaged triac (shorted) • Failed Engine Board • Failed fusing thermopile • Failed fusing thermistor • Abnormal fusing control software behavior • The PWM signal is continuously supplied from the IH inverter (due to a software or temperature Sensor error).
• Remedy: • Clear the SP: fusing SC. • Replace the PSU. • Replace the Engine Board. • Replace the fusing thermopile. • Replace the Fusing Unit.
