 All About this machine
  • Code: E537
  • Description: Fuser Fail
    - Control Thermistor detected a temperature exceeding the specified temperature. Safety Thermistor detected a temperature exceeding the specified temperature.
    - The Control Thermistor did not detect a Ready even though the specified time elapsed from Main Lamp ON at Warm Up.
    - The Main Lamp continues to stay lit even after time specified for the Main Lamp elapsed after the Control Thermistor detected a Ready.
    - The Control Thermistor detected a temperature below the specified temperature even after the specified time elapsed from Main Lamp ON at Warm Up.
    - The latch lever of FUSER ASSY is set incorrectly.
  • Causes: • FUSER ASSY • HARNESS ASSY MCU C/L • FFC-ASSY LV/MCU • HARNESS ASSY AC • PWBA FUSER CONT • LV/HVPS • HARNESS ASSY MAIN • PWBA MCU
  • Remedy: 1 Check of FUSER ASSY attachment Is the FUSER ASSY attached correctly to the printer? In particular, is the connector connected firmly to the printer? Is the connector latched normally? Go to Step [3]. Re-attach, and go to step [2]. 2 Does the error recur when the power is turned ON? Go to Step [3]. End of procedure 3 Check after replacement of the FUSER ASSY Replace FUSER ASSY. Does the error recur when the power is turned ON? Go to Step [4]. End of procedure 4 Continuity check of HARNESS ASSY MCU C/L Allow FUSER ASSY to cool down before performing work. Remove FUSER ASSY. Is the continuity normal between all terminals of J614A . J417 and J614 . J3? Go to Step [5]. Replace HARNESS ASSY MCU C/L. 5 Continuity check of FFC-ASSY LV/MCU Disconnect P/J401 from PWBA MCU and P/ J500 from LV/HVPS. Do all of the wiring below have normal continuity? P401-21 . J500-2 P401-22 . J500-1 Go to Step [6]. Replace FFCASSY LV/MCU. 6 Continuity check of HARNESS ASSY AC Disconnect P/J503 from LV/HVPS and P/J2 from PWBA FUSER CONT. Do all of the wiring below have normal continuity? J503-5 . J2-5 J503-6 . J2-6 Go to Step [7]. Replace HARNESS ASSY AC. 7 Check after replacement of PWBA FUSER CONT Replace PWBA FUSER CONT. Does the error occur when the power is turned ON? Go to Step [8]. End of procedure 8 Check after replacement of LV/HVPS Replace LV/HVPS. Does the error occur when the power is turned ON? Go to Step [9]. End of procedure 9 Continuity check of HARNESS ASSY MAIN Disconnect P/J1 from PWBA FUSER CONT and P/J410 from PWBA MCU. Do all of the wiring below have normal continuity? P/J1-1 . P/J410-10 P/J1-3 . P/J410-9 Replace PWBA MCU. Replace HARNESS ASSY MAIN.
