• Code: C3425
• Description: Fusing warm-up trouble. • Detected temperature of the heating roller temperature sensor (TEMS) does not go up a given range of temperature even after a lapse of given period of time at warm up. • The temperature detected by the heating roller temperature sensor (TEMS) does not shift from the pre-standby state or the post-print color printing-enable wait state even after the lapse of a predetermined period of time after the completion of warm-up.
• Causes: • Fusing unit • Heating roller temperature sensor (TEMS) • DC power supply (DCPU) • 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 connector between the fusing unit-relay CN3-DCPU CN002 for proper connection and correct as necessary. 4. Check the connector between the fusing unit-relay CN4-MFPB CN16E for proper connection and correct as necessary. 5. Replace the fusing unit. 6. Replace MFPB. 7. Replace DCPU.
