My advice for the HP CP4025 and CP4525 50.1 Fuser Error Message

  1. Turn the machine off then back on. Unplug the machine and let it sit 15 to 20 minutes then plug back in and try again.
  2. Check the power source. Make sure the machine in plugged into a wall outlet and no other large devices are plugged into the same circuit. This happens more in older homes and buildings.
  3. No powerstrips or battery back ups. Battery backups can put a huge strain on the power supply.
  4.  Remove and reseat the fuser. Check the connectors on the heating element and make sure they are fully seated.
