Code: C3426
Description: Fusing temperature increase malfunction (TEM1: edge) • Detected temperature of the fusing temperature sensor/1 (TEM1: center and edge) does not go up a given range of temperature even after a lapse of given period of time at warm up. • The warm-up is not completed even after the set period of time has elapsed after the warm-up is started.
Causes: • Fusing unit • C3421: Fusing temperature sensor/1 (TEM1: center) • C3426: Fusing temperature sensor/1 (TEM1: edge) • DC power supply (DCPS) • MFP board (MFPB)
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 CN13E, DCPS CN2 for proper connection and correct as necessary. 4. Replace the fusing unit. 5. Replace MFPB. 6. DCPS F102 conduction check 7. Replace DCPS.

Code: C3722
