Hey @laceyahrens,
Welcome to the HP Support Forums!
I understand that you are having some issues with an error code on your Envy 4500 e-All-in-One Printer. I can help you with that.
First, make sure the printer is plugged directly into a wall outlet and not a surge protector. Once that is done this document would outline how to troubleshoot error messages on your printer, however it sounds like you have already performed all troubleshooting steps.
The last thing to do would be to contact HP Support by clicking on this link and filling out the form at the bottom to discuss options based on your warranty.
Please let me know if this resolves your issues or if you have any other questions. Otherwise, have a great week!
If this resolves your issues, please help other users find this thread by clicking on Accept Solution below my post.
