Solution:

1. Turn the printer off and allow it to cool down. 2. Reinstall the fuser, and check the connector (J100) that connects the fuser and the printer. Replace the connector if it is damaged. 3. Turn the printer off and remove the fuser. Measure the resistance between the connector pins on the fuser. If resistance does not meet the following guidelines, replace the fuser. J100LB-5 to J100LB-6: 300 - 500 KOhms J100LB-1 to J100LB-2: less than 1 KOhm 4. Check for continuity between connector pins J100-5 and J100-6. If there is no continuity, replace the fuser. 5. Replace the fuser power supply PCB. 6. Replace the DC controller PCB. Calibrate the printer after replacing the DC controller. See Calibrate now (HP Color LaserJet 5500 models only).
