Description: IOT Fuser Failure The Temp Sensor detected abnormally high temperature. Open circuit of the Temp Sensor was detected. The Temp Sensor detected abnormally low temperature. The FUSER ASSY did not reach the setting temperature within the specified time. When the motor was stopped after the FUSER ASSY had reached the setting temperature, the Heater Lamp remains ON for 10 seconds.
Remedy: 1 Check the installation of the FUSER ASSY Is the FUSER ASSY installed properly? Go to Step 2 Reinstall the FUSER ASSY 2 Check the connection of the FUSER ASSY Check the connections between FUSER ASSY and MCU PWB, between FUSER ASSY and LVPS, as well as between LVPS and MCU PWB. Are P/J4410, P/J12, P/J32, P/J33, and P/J21 connected securely? Go to Step 3 Connect P/J4410, P/J12, P/J32, P/J33, and P/J21 securely 3 Check the conductivity of the HARNESS ASSY FSR Is the wire between P/J4410 <=> P/J32 conducting properly? Go to Step 4 Replace the HARNESS ASSY FSR 4 Check the conductivity of the HARNESS ASSY MAIN FRM Is the wire between P/J4410 <=> P/J12 conducting properly? Go to Step 5 Replace the HARNESS ASSY MAIN FRM 5 Check the conductivity of the HARNESS ASSY PS Is the wire between P/J33 <=> P/J21 conducting properly? Go to Step 6 Replace the HARNESS ASSY PS 6 Check after the replacement of FUSER ASSY Replace the FUSER ASSY. Does an error occur? Go to Step 7 Procedure is complete 7 Check after the replacement of LVPS Replace the LVPS. Does an error occur? Replace the MCU PWB Procedure is complete

Description: Fuser Life Warning The FUSER ASSY needs to be replaced soon. (The number of printed sheets had exceeded the specified number.
Causes: FUSER ASSY (PL8.1.11) MCU PWB (PL11.1.3)
Remedy: 1 Check after the replacement of FUSER ASSY Replace the FUSER ASSY with a new one. Enter the CE mode and execute the following menus to clear the FUSER ASSY life counter. Parameter / Life Counter / Fuser / Trans / Reset Counter Does an error occur? Replace the MCU PWB Procedure is complete
