50.4 Fuser Error on HP Color LaserJet CP2025
If you are seeing a 50.4 Fuser Error on your HP Color LaserJet CP2025, you probably need to replace the fuser. The printer is registering a "fuser heater wire failure". Fusers are a consumable part; it is expected over the life of the printer you will replace the fuser several times. HP estimates average fuser life to last about 100,000 pages; but a fuser can fail much earlier depending on printing conditions, heavy paper jams, and the quality of the fuser installed.
For a temporary fix, you can try turning the printer off and back on again, sometimes the reboot will reset the fuser so you can continue printing a few more pages. If the 50.4 Fuser Error returns, you should replace the fuser.
See the links below for information on purchasing a replacement fuser and for installation instructions. Keep in mind that on this model replacing the fuser is considered an involved procedure.
