Hi @Jkayross,
Welcome to HP Forums, this is a great place to get support, find answers and tips.
Thank you for posting your query, I'll be more than glad to help you.
I understand that you are unable to scan or copy from your HP ENVY 4502 e-All-in-One Printer.
This issue could occur if the scanner mechanism is not working.
Let's go through a few steps to troubleshoot this issue.
In order to isolate the issue between the software and the hardware of the unit, I suggest that you make a copy from the control panel of the unit.
You may check this link on how to make a copy: Copying Documents
If the copy is fine, then it is a software issue else a hardware issue with the scanner.
If the copy is fine, then you may follow the steps in the links below depending on how it is connected to the computer:
1. USB Scanner Connection Error (Windows)
2. Network Scanner Connection Error (Windows)
Let me know how this works.
You have a good day ahead.
