Pressure Roller Thermistor (Center) Disconnection (Low Power)

 

 

In Machine Condition A, after turning the fusing lamp on, the pressure roller thermistor (center) (TH3) has detected the temperature of 0°C or below continuously for 20 seconds.

Machine Condition A refers to any of the following conditions:

  • In Warm-up mode
  • At start-up and restart-up
  • Rotation after reload
  • Before/while/after printing
  • In Ready mode
  • In Panel Off mode
  • In Low Power mode
  • Thermopile disconnection
  • Thermistor disconnection
  • Connector error (disconnected, loose)
  1. Check the power supply voltage and reconnect the cable to the outlet. (-05 only)
  2. Reconnect the connectors (between the fusing unit and the BICU).
  3. Replace the pressure roller thermistor (center) (TH3).
  4. Replace the fusing unit.
  5. Replace the harness between the fusing unit and the BICU or the PSU (AC controller board).
  6. Replace the BICU (PCB10).
  7. Replace the fusing sleeve belt unit.
  8. Replace the PSU (AC controller board) (PCB9).

In Machine Condition B, after turning the fusing lamp (center) on, the pressure roller thermistor (center) (TH3) has failed to reach 40°C in 12 seconds.

Machine Condition B refers to any of the following conditions:

  • In Warm-up mode
  • At start-up and restart-up
  • Thermistor dirt
  • Thermistor modification/float
  • Outside input voltage guarantee
  • After excessive temperature rise prevention unit operation
  1. Check the power supply voltage and reconnect the cable to the outlet.
  2. Clean or replace the pressure roller thermistor (center) (TH3).
  3. Replace the fusing sleeve thermostat.
  4. Replace the fusing sleeve belt unit.
  5. Replace the harness between the fusing unit and the BICU or the PSU (AC controller board).
  6. Replace the thermopile (center) (TH1).
  7. Replace the BICU (PCB10).
  8. Replace the PSU (AC controller board) (PCB9).

Pressure Roller Thermistor (Center) High Temperature Detection (software)

The pressure roller thermistor (center) (TH3) has detected the temperature of 230°C or higher continuously for 1 second.

  • Triac short-circuit
  • IOB board defective
  • BICU board defective
  1. Check the paper settings.
  2. Check the paper position in the paper feed tray.
  3. Reconnect the connectors (main machine side, BICU side).
  4. Remove the jammed paper between the center thermopile and fusing unit.
  5. Clean or replace the thermopile (center) (TH1).
  6. Replace the harness between the fusing unit and the BICU or the PSU (AC controller board).
  7. Replace the BICU (PCB10).
  8. Replace the PSU (AC controller board) (PCB9).
  9. If the problem cannot be solved after performing the above steps, replace the fusing unit.

Paper Exit/ Pressure Release Motor Error Detection

Retry operation fails 3 times consecutively.

  • Pressure roller HP sensor (S26) disconnected
  • Pressure release encoder modification
  • Fusing unit defective
  • Paper exit/ pressure release motor disconnected

Inspect the pressure roller HP sensor (S26) with SP5-803-047.

If no response from the sensor, perform steps 1 and 2.

  1. Check the connection of the pressure roller HP sensor (S26).
  2. Inspect the pressure roller HP sensor (S26).
  3. Inspect the pressure release encoder.
  4. Replace the fusing unit.
  5. Check the connectors of the paper exit/ pressure release motor (M4).
