When I am prompted with entering my serial number, it is deemed invalid, even though it is correct.

Note, this support menu does not allow me to select printer scanning, faxing, etc. but rather forces me to select notebooks.

Hi @John_Staley,

Welcome to the HP Support Community. 

I'd be happy to help you! 

Are you trying to register the printer from the HP website?

Or are you trying to check the warranty of the printer?

To be able to answer you effectively, we need some information.

May I have the exact product name and serial number? Refer to this document for steps to find the product details. Do not share any of your personal information such as serial, phone number, email ID, etc.
