Error Code:

Code: C3452
Description: Press. heater trouble
• When the warm up started, if the temperature detected by the fusing pressure roller thermistor/1 (TH2) is at the specified value or under, and lower than the temperature detected by the heating roller thermistor/1 (HT1) for a specified degree, the highest temperature and the lowest temperature detected by the fusing pressure roller thermistor/1 (TH2) are compared for the specified period of time. The malfunction will be detected if the temperature difference is either lower than specified or at the specified value or over. • Voltage for the fusing pressure roller heater lamp (H3) at the time of stand-by after the warm up will be measured to be set as the reference value. After the temperature adjustment for the fusing pressure roller, if the temperature detected by the fusing pressure roller thermistor/1 (TH2) is lower than the specified, the voltage will be measured again to be compared with the reference value. The malfunction will be detected when the difference between the reference value and the measured value is at the specified value or over for the specified period of time.
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, MFPB and DCPU for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change MFPB. 6 Change DCPU.
