Hello bnewt, and welcome to the HP Forums, I hope you enjoy your experience!
I see you are having scan issues. I would love to try and help you, but I do need a little information first. I am linking an HP Support document below that will show you how to find your product number. With the product number we can provide you with accurate information.
How Do I Find My Model Number or Product Number?
Please let me know when you have gathered the information. Thanks for posting on the HP Forums.
