Description: Fusing abnormally low temperature detection (center)
Detected temperature of the heating roller thermistor (TH2; center) goes below a given temperature for a given period of time consecutively after warm up is completed.
Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the open/close operation of the right door. 3 Check the fusing unit CN30-PRCB CN16, fusing unit-relay CN4AC-DCPU CN2 for proper connection and correct or change as necessary. 4 Change fusing unit 5 Change PRCB 6 Change DCPU
Code: 0511
Description: Fusing abnormally low temperature detection (edge)
