Hello, this is Emily.
If the scanner doesn't work but the copy feature works, then I would definitely help make sure it is not a driver issue, as scanner requires its own driver in addition to the printer driver, or you need the full feature driver (includes both).
However, copier doesn't require driver and it is a feature you do directly on the device, without needing the computer. So if it is not copying, considering both scanner and copier requires the mirror and its components, I think this is a hardware issue directly on the HP device. In that case, troubleshooting here as a Windows or Microsoft issue is not the right direction. You need to get in touch with HP support in this case. https://support.hp.com/us-en
