• Code: E-0905, E-2309
• Description: Fuser Over-Temp at Thermistor 2 Error
• Causes: 1. Thermistor 2 detects that the Fuser Temperature is over 200 deg C. 2. The signal from FPGA on PW13555 (Fuser Thermistor 2 High-temperature Abnormality) shows "H" for longer than 1 second.
• Remedy: Output Check Mode No. 00600 SSR1 (H1: Center) Output Check Mode No. 00601 SSR2 (H2: Side) Information Mode No. 00013 Detection Temp1 Information Mode No. 00014 Detection Temp2 Check if relevant “IR Lamp” is possible to operate in Output Check Mode.
  1. In case the Item is Inoperative. (IR Lamp lights but not turn OFF) Wiring Harness 1 Following connectors and wires are OK. J224 on PW13520, TB1 to TB4 on SSR1/SSR2, TB101 to TB108 on AC Terminal PW14210, TB0 to TB8 on RY2. No Correct SSR1 2 If IR Lamp (H1: Center) is lighting while Output Check No. 00600 SSR1 status is “Inactive”. Please check voltage between SSR1-3 and SSR1-4. (Also between SSR1-4 and F-GND.) Yes In Case SSR1-3 and SSR1-4 is 0V DC, replace SSR1. In Case SSR1-4 and F-GND is 0V DC replace PW13520 or check the wiring. SSR2 3 If IR Lamp (H2: Center) is lighting while Output Check No. 00601 SSR2 status is “Inactive”. Please check voltage between SSR2-3 and SSR2-4. (Also between SSR2-4 and F-GND.) No In Case SSR2-3 and SSR2-4 is 0V DC, replace SSR2. In Case SSR2-4 and F-GND is 0V DC replace PW13520 or check the wiring. PW13555 4 Replacing PW13555 PCB recovers the error condition.
